feat(prompt): 重新注册 bash，把"不要用 bash 搜索"写进工具描述

真实会话里模型仍习惯性先调 bash grep，被拒后才改用 grep 工具；系统提示词里已有 4 处
提醒，但模型下调用决定时看的是工具 schema 描述，而 Pi 内置 bash 描述对此只字未提。

- 新增 extensions/bash-override.ts：用 Pi 的 createBashToolDefinition 重新注册 bash，
  执行、输出结构与 codemode 说明完全沿用上游；shellPath/commandPrefix 按 ctx.cwd
  经 SettingsManager 惰性解析，与内置一致
- tools.jsonc 新增 descriptionAppend 字段，由 prompt-guard 注册时拼接到上游描述后
- bash 增加命令→工具对照规则（grep -n / grep -rl / find -name），并提示
  文件清单用 $(git ls-files) 传参、不要接 xargs（会触发权限审核）

 # 仓库说明
 
-本仓库用于维护可通过一次 `pi install` 部署的个人 Pi 扩展组合包。根 `package.json` 是唯一的组合包安装入口；根 `install.sh`、`update.sh` 和 `uninstall.sh` 只是对 `pi install` / `pi update` / `pi remove` 的便捷包装，不形成第二套部署机制。依赖、默认行为和必要配置必须由组合包自身声明或部署，不把安装后的手工配置作为默认流程。每个自维护扩展使用独立的顶层目录，扩展源码、测试和说明应保留在各自目录内。
+本仓库维护可通过一次 `pi install` 部署的个人 Pi 扩展组合包。根 `package.json` 是唯一的组合包安装入口；`install.sh` / `update.sh` / `uninstall.sh` 只是 `pi install` / `pi update` / `pi remove` 的便捷包装，不形成第二套部署机制。仓库 `config/` 是组合包唯一配置来源，扩展运行时直接读取已安装组合包内的文件，不复制、不播种、不迁移；仅外部 npm 扩展固定读取 agent 目录路径时（当前 `hashline.json`、`lsp.json`）才允许加载时从 `config/` 覆盖写入。每个自维护扩展使用独立顶层目录；各扩展的维护约定见各自目录的 `AGENTS.md`（`extensions/` 下 wrapper 见 `extensions/AGENTS.md`），上游来源记录见各自 `UPSTREAM.md`（中文维护）。

-## 当前职责与默认行为
+## 全局硬规则
 
-- FFF 独占本地字面搜索；远端服务器由独立的 `ssh_find` / `ssh_grep` 结构化工具在已授权调用内自适应使用现有命令。RTK 不得处理本地或远端搜索工具的调用/结果，也不得通过默认命令改写接管 `rg`、`grep`、`find`、`fd`。
-- RTK 默认只压缩非搜索输出，包括本地 `bash` 与远端 `ssh_bash` 的 ANSI 清理、测试聚合、构建过滤、Git 压缩、Lint 聚合和兜底截断；`ssh_bash` 只复用输出处理，远端命令不得进入 RTK rewrite。
-- `commandRewritingEnabled` 默认 `false`。默认安装不依赖系统 `rtk` CLI；只有用户主动开启命令改写时才需要 `rtk rewrite`。
-- `readCompaction.enabled`、`sourceCodeFilteringEnabled` 和 `smartTruncate.enabled` 当前均默认 `false`，源码读取保持原样。未经用户明确决定，不因节省上下文而改变这些默认值。
-- 若以后开启 read 压缩，优先考虑 `readCompaction + smartTruncate`，源码过滤仍独立评估；必须保留精确 `offset/limit` 读取、短文件和行锚点的完整性。
-- Context Mode 负责避免批量读取、命令研究和网页原始内容直接撑大上下文；FFF 仍负责精确字面搜索，RTK 仍处理未走 Context Mode 的普通输出。
-- Hashline 默认以 2 字符行哈希覆盖内置 `read` / `edit`，`grep` 和 `replaceText` 均关闭；它保证锚定编辑而不负责压缩，大文件上下文节省必须来自先定位/隔离分析、再做最小范围 `offset/limit` 读取。
-- 工具路由规则不得替换 Pi 默认系统提示词：代码结构、调用关系和待修改 symbol 优先 CodeGraph，定义/引用/类型/诊断优先 LSP；工作区内大文件探索、分析和总结优先 `ctx_execute_file`，日志、构建与不可预测命令输出优先 Context Mode；字面搜索先用 FFF `find` 收敛文件位置，再在收敛路径内用 `grep`/`multi_grep` 获取行号；真正修改前才用小范围 Hashline `read` 获取新鲜锚点并用锚定 `edit`。在线搜索按场景只先选一个服务：广泛发现、新闻和候选来源用 Tavily，官方/技术/论文和高确定性来源用 Exa，中文、站点限定和日期筛选用 Keenable；只有必要时才跨服务复核。遇到大量结果、截断或上限时继续缩小范围，不得靠提高 limit 或倾倒全部结果解决。
-- `ask_user_question` 只用于模型继续任务所必需的用户决定、偏好、确认或澄清；不得重复询问直接用户消息中已有的信息。工具仅支持交互式 TUI、顺序执行和最多 8 题；取消或 abort 必须返回 `cancelled: true`，不得伪造答案，且 `/qna` 不属于该扩展。其成功 `details.answers` 必须保留 `question` / `answer` 字段，以匹配 AutoReview 已有的可信结构化用户交互边界。
-- Tool Search 默认常驻核心 `read` / `write` / `edit` / `bash` / `grep` / `find`、`codegraph_explore`、`lsp_diagnostics` 与 `tool_search`；其余组合包工具必须优先使用 `pi-tool-search/extensions/bundle-groups.ts` 中提交的权威工作流分组。默认最多 3 个动态组、模型组最多 8 个工具、动态工具总数最多 20，加载或组内调用更新 LRU，超限先移除最久未用组。
-- `pi-chrome` 在未授权时不注册 Chrome 工具；显式授权后出现的 21 个 `chrome_*` 工具必须由 Tool Search 分入 `chrome-navigation`、`chrome-interaction`、`chrome-debugging`，不得落入 unknown-tools 模型增强路径。Tool Search 重新激活 schema 不能替代上游每次执行时的授权校验。
-- 标准组合包工具全部命中预置目录时 Tool Search 不得调用模型、创建用户缓存或发送隐藏 schema。只有存在未识别第三方工具时才允许惰性模型增强；生成结果必须保留全部预置 assignment，模型元数据不得替代真实名称、参数或 schema。缓存必须位于 agent 目录且权限 `600`；模型失败必须继续使用预置目录 + 确定性未知工具分组。`groupOverrides` 优先级高于预置分组。
-- Tool Search 必须直接使用当前 `@earendil-works/pi-coding-agent`、`typebox`、`ModelRegistry.complete()` 和 `setActiveTools()`；首次纯增加载使用当前 Pi 的增量结果传播，LRU 替换允许走宿主安全 fallback。不得安装或映射旧 `@mariozechner` runtime，不得恢复 provider payload 改写、代理分发或隐藏 `sendMessage` steer/retry 兼容循环。
-- `.pi-debug/` 是 `/dump-system-prompt` 生成的本地诊断目录，不提交到仓库，也不作为组合包运行时配置源。
-- CodeGraph MCP 扩展只配置 Pi 到外部 `codegraph` 命令的连接。根包安装本身不安装 CodeGraph；便捷脚本仅在组合包安装完成且用户明确选择 `Y` 后调用官方安装器。安装、升级和普通启动流程不得执行 `codegraph init`；只有用户在目标项目显式调用 `/plugin_init` 并确认后，命令才可以 `.codegraph/codegraph.db` 与 `.hippo/hippo.db` 为权威标志初始化缺失状态。命令必须先预检两个 CLI，任一步失败不得热重载，也不得隐瞒此前已完成的部分初始化；不得改动 CodeGraph 更新或遥测设置。
-- CodeGraph MCP 使用 `keep-alive` 并只直接暴露 `codegraph_explore`；命令缺失、项目未初始化或连接失败时不得阻止其他扩展加载。
-- 所有 MCP 服务必须合并到 `extensions/mcp.ts` 创建的唯一 `pi-mcp-adapter` 实例；不得新增独立 adapter 扩展入口，否则会重复注册 `--mcp-config`、`/mcp` 等全局接口。根测试必须扫描全部本地扩展入口并强制这一不变量。
-- Exa MCP 使用托管 Streamable HTTP 端点和 `eager` lifecycle；`EXA_API_KEY` 通过 `x-api-key` 请求头发送，不得放入 URL、仓库文件或日志。所有在线搜索工具统一采用“来源名 + 原始语义工具名”的命名形式，例如 `tavily_web_search`、`exa_web_search`、`keenable_search`。Exa 高级搜索必须显式约束结果数量和文本长度；Tavily 输出默认控制 `max_results` 且非必要不请求 raw content；Keenable 优先利用中文、站点和日期筛选能力。
-- 搜索 key 默认保存在 `${XDG_CONFIG_HOME:-$HOME/.config}/my-pi/search.env`，文件必须为 `600` 且不得提交；`search_config.sh` 只输出配置状态，禁止回显 key。
-- `pi-context-view` 只观察上下文占用，不参与压缩策略。
-- `pi-condense` 负责压缩已经进入会话的历史工具结果，与 Context Mode 的输入隔离职责互补；`extensions/condense.ts` 只在 `settings.json` 尚无 `contextPrune.enabled` 时写入 `true`，必须保留用户显式设置的 `false`，配置无效时不得覆盖原文件。其他参数沿用上游默认，包括 `agent-message` 触发模式和 skill 路径保护。
-- Codex fast mode 只为符合条件的 `openai-codex-responses` 请求设置 priority service tier。`/fast-mode on|off` 同时更新当前分支记录与 Pi agent 目录中的 owner-only 全局默认值；新会话继承全局值，已有分支记录优先，配置缺失或无效时回退为关闭。
-- 权限策略默认允许常规工具，允许 FFF 工具；拒绝 Bash 直搜和敏感凭据路径；Git 非只读操作、包管理、外部目录、文件/系统/网络高风险操作与普通 MCP 调用先由 `pi-permission-system` 判为 `ask`。
-- SSH 权限沿用同一条 `pi-permission-system` gate 与 `auto-review` authorizer chain：`ssh_connect`、`ssh_read`、`ssh_write`、`ssh_edit`、`ssh_find`、`ssh_grep` 默认 `ask`；连接前的证据解析已导入 host ID 为非秘密 target、port 与请求/default cwd，AutoReview 只可依据用户直接消息中的明确目标授权连接。`ssh_bash` 通过 `shellTools` 映射到完整 Bash 策略并设置 `decisionFloor: "ask"`，把普通 Bash `allow` 提升为复核请求，同时保留原有 `ask` 与硬 `deny`。远端路径不得送入基于本机 cwd 的 `path` / `external_directory` 归一化。
-- `pi-permission-auto-review` 不是独立 `tool_call` gate，而是 `pi-permission-system` authorizer chain 中名为 `auto-review` 的链路；只复核权限基线产生的 `ask`，不会重复处理已 `allow` 或已 `deny` 的请求。
-- reviewer 返回 `allow` 时自动批准、返回 `deny` 时直接拒绝，配置、模型、认证、超时或响应异常时必须 `defer` 到正常人工提示。`pi-permission-system` 的 delegation envelope 继续禁止 authorizer 自动批准全部 `path` 请求；`external_directory` 对内置只读路径工具（`read`、`find`、`grep`、`ls`）接受 reviewer 的 `allow`，写入、编辑、Bash、未知工具和其他外部访问仍转人工。
-- 默认 reviewer 为 `openai-codex/codex-auto-review`、low reasoning、90 秒总重试预算和内置 Codex Guardian 风格策略；只把 active branch 中的直接用户消息与已识别结构化问答作为授权证据，assistant/tool/compaction 内容不能自行授权。
-- `config/pi-permission-system.json` 必须显式配置 `authorizerChain: ["auto-review"]`，并把需要自动复核的 Git 非只读操作、包管理及其他类别声明为 `ask`；硬 `deny` 不得改成可由模型覆盖的 `ask`。
-- `pi-lsp` 的 TypeScript/JavaScript 后端由根包固定依赖提供，`extensions/lsp.ts` 使用当前 Node 可执行文件直接启动包内 `typescript-language-server` CLI，不得依赖或调用 VS Code GUI；Kotlin/JDT LS 仍使用组合包部署的 `kotlin-lsp --stdio` 与 `jdtls` 配置，根包不安装这两个系统可执行文件，便捷脚本可在用户逐项明确确认后通过 Homebrew 安装 Kotlin LSP、Java 21 和 JDT LS。
-- 终端环境配置只属于便捷脚本：Kitty 可选安装后可通过官方 kitten 启用 Solarized Dark；Oh My Zsh 使用不切换 shell 的 unattended 安装；Powerlevel10k 将仓库内置的 `config/p10k.zsh`（Rainbow/ASCII 单行紧凑主题）部署到 `~/.config/my-pi/p10k.zsh`（遵循 `XDG_CONFIG_HOME`），不得覆盖用户自己的 `~/.p10k.zsh`。`.zshrc` 中脚本拥有的内容必须使用 `# >>> my-pi:<id> >>>` / `# <<< my-pi:<id> <<<` 受管块，更新时只替换块内内容；标记不完整或重复时拒绝修改。实际修改前必须创建带时间戳的备份。`git`、`zsh-autosuggestions`、`zsh-syntax-highlighting` 在安装流程中逐项询问后才安装或启用。
-- Codex 远程压缩只对 `openai-codex` 生效，默认在 turn boundary 达到 90% 时触发；官方 Hippo Extension 在已初始化项目的 session start 注入上下文、过滤捕获工具错误，并在 session shutdown 执行 `hippo sleep`。
-- Hippo Extension 直接使用 PATH 中的官方全局 `hippo` CLI；`install.sh` 只在 CLI 缺失且用户明确确认后安装 `config/hippo-memory-version` 指定的 npm 版本，不得扫描项目、选择初始化目录或执行 `hippo init`。用户必须在自己选择的项目目录中手动初始化。
-- `update.sh` 只升级已经安装且属于 npm 全局包的 Hippo CLI；必须从 `pi update` 后的组合包读取目标版本，先用 `npm view` 确认，再比较本地版本，版本相同不得重新安装，CLI 缺失或来源未知时保留现状。
-- `uninstall.sh` 只在根包移除成功后询问是否卸载 npm 全局 Hippo CLI，默认拒绝；不得删除项目 `.hippo/`、全局记忆或旧 Hermes 数据。
-- `install.sh` 默认从 `git:git@bitbucket.org:siakitem/my-pi.git` 安装，并允许用 `PI_PACKAGE_SOURCE` 覆盖来源；组合包安装失败时立即停止，机器级依赖安装失败时继续检查其余依赖并最终返回非零状态。
-- CodeGraph 的可选安装使用官方远程安装脚本；macOS Kitty 使用 Homebrew cask，其他系统使用 Kitty 官方安装器；Kotlin LSP、Java 21 和 JDT LS 使用 Homebrew；Oh My Zsh 使用官方安装器，Powerlevel10k 与两个第三方 Zsh 插件从各自官方 Git 仓库克隆。升级时 Git checkout、Homebrew 包、Kitty 官方安装和 CodeGraph 都必须先比较本地与远端版本，版本一致时不得重新下载安装；无法可靠比较时保留现状并报告。缺少 Homebrew、curl 或 git 时保留已经完成的组合包安装并报告失败。
-- `install.sh` 不检查默认不需要的 `rtk` CLI；`update.sh` 和 `uninstall.sh` 使用同一个 `PI_PACKAGE_SOURCE` 规则分别调用 `pi update` 和 `pi remove`。运行 `update.sh` 视为明确授权升级已安装组件及同步已有受管配置，但不得安装缺失组件或改写受管块之外的用户配置；卸载仅可在用户当次明确确认后移除 npm 全局 Hippo CLI，其他共享机器级工具保持不变。
-
-## 修改边界
-
-- 优先在目标扩展目录内完成改动；不要让一个扩展依赖另一个扩展的未公开内部实现。
-- 保留原项目的 `LICENSE`、版权信息和必要的来源说明。
-- 扩展运行目录中的 `config.json`、日志、构建产物、覆盖率目录和依赖目录属于本地状态，不应提交；`config/pi-permission-system.json`、`config/pi-hashline-edit.json` 与 `config/lsp.json` 分别是权限链、Hashline 默认行为和 LSP 后端的组合包权威源配置，必须提交并维护。
-- 外部 Pi 扩展依赖必须在根 `package.json` 中使用精确版本，自维护 Fast mode 等扩展必须使用本地 `file:` 依赖，并更新根 `package-lock.json`；不要用仓库级 `.pi/settings.json` 代替组合包依赖。
-- 需要原生构建的依赖只按锁定版本加入根 `allowScripts`；当前 `better-sqlite3@12.11.1` 仍由 Context Mode 使用并保持精确放行。官方 Hippo CLI 是独立机器级 npm 包，不得因此向根包批量批准其他 install scripts。
-- Pi 核心包只作为宿主 peer dependencies，不得在组合包内再安装或打包一套 Pi runtime；保留根 `.npmrc` 的 peer 安装策略。
-- `pi-tool-search/` 的根依赖必须保持 `file:./pi-tool-search`，组合包直接加载 `pi-tool-search/extensions/index.ts`；同步上游时先核对本地增量动态工具改造，禁止用旧 npm 入口或上游旧宿主实现直接覆盖。
-- 上游仅作为参考来源。同步上游改动时先核对本仓库已有修改，再按明确范围移植；不要直接覆盖本地实现。
-- `install.sh`、`update.sh`、`uninstall.sh` 和 `search_config.sh` 必须保持 POSIX `sh` 兼容和可执行权限，并包含在根 `package.json` 的 `files` 中；修改脚本行为时同步更新 README 和本文件。
-- 安装流程中的机器级依赖和用户终端配置必须保持逐项询问且默认拒绝，不得在没有用户明确确认的情况下自动安装或改写。用户主动运行 `update.sh` 只授权升级已安装项和同步已有受管配置；缺失项仍必须跳过。`.zshrc` 修改必须局限于受管块并保留备份，卸载不得顺带删除或还原共享工具和用户终端配置。
-- 未经明确要求，不执行发布、提交、推送、运行安装/卸载脚本或安装到用户 Pi 运行目录等外部写操作。
-
-## 根目录 TypeScript 与 LSP 验证约定
-
-- 根目录当前有意不安装 Pi runtime，也没有根级 `tsconfig.json`、`devDependencies` 或 `@types/node`；`@earendil-works/pi-*` 只作为 optional host peer dependencies。TypeScript LSP 因而会把根目录 `.ts` 文件放入 inferred project，不能把宿主 Pi 的运行时解析能力等同于仓库内静态类型环境。
-- 每个任务首次对相关根目录 TypeScript 文件调用 `lsp_diagnostics` 时先建立并记录基线；后续只关注相对基线新增、消失或位置变化的诊断。文件和类型环境都未变化时不得重复调用 LSP 并重复报告同一组结果。
-- 当前可预期的基线包括：宿主 peer 缺失导致的 `TS2307`（例如找不到 `@earendil-works/pi-coding-agent`），Node 类型缺失导致的 `node:*` / `node:test` / `node:assert` `TS2591`，以及由这些上游类型缺失级联产生的 `TS7006`、`TS18048`、`TS2722` 等。遇到级联错误时先确认其是否随缺失类型而产生，不要把它们直接归因于本次实现。
-- 已知基线不等于忽略所有诊断：凡是无法由上述缺失依赖解释的新语法错误、结构类型错误、错误属性访问或本次修改所在代码的新诊断，必须修复并重新验证。交付时应把“已知类型环境基线”和“本次新增诊断”分开说明。
-- 不得为了消除 LSP 基线而在根包安装第二套 Pi runtime、加入机器相关的宿主绝对路径或提交只在单机有效的 `paths` 映射。若确需新增根级 `tsconfig.json`、`@types/node` 或其他开发类型环境，必须作为明确的仓库设计变更评估，并同步更新依赖、锁文件和本文档。
-- 不要从泛型或重载的 `ExtensionAPI` 方法直接用 `Parameters<...>` 猜取具体工具定义；解析失败时它可能退化为 `unknown`。包装第三方工具时优先使用上游导出的具体类型；没有稳定导出时定义覆盖实际访问字段的最小结构类型，并用运行时集成测试验证。
-- `node --test` 可直接测试仓库内的纯 TypeScript helper，但测试入口不得静态导入 `node_modules` 中的 `.ts`；Node 原生 type stripping 会对这种路径报 `ERR_UNSUPPORTED_NODE_MODULES_TYPE_STRIPPING`。第三方 TypeScript 扩展 wrapper 应拆出本地纯 helper 做单元测试，并通过隔离的临时 Pi agent/jiti 加载验证真实扩展入口。
-- 对根目录扩展的最终验证优先组合使用：纯 helper 的 `node --test`、`git diff --check`、所需 npm 锁文件检查，以及隔离 Pi 环境的扩展加载。LSP 启动成功、单元测试通过和真实 Pi 加载通过是不同证据，不得互相替代或把类型环境基线误报为 LSP 后端启动失败。
-
-## `pi-rtk-optimizer` 开发约定
-
-- 组合包运行环境为 Node.js 22.19 或更高版本；RTK 子目录开发验证还需要 npm、Bun 和项目声明的开发依赖。
-- 扩展入口是 `pi-rtk-optimizer/index.ts`，主要实现位于 `pi-rtk-optimizer/src/`。
-- RTK 命令改写默认关闭；若用户主动开启，其命令支持策略由已安装的 `rtk rewrite` 决定，不在扩展内重复维护规则。
-- FFF override 独占搜索工具与搜索输出；RTK 不得处理 `grep` 工具结果。
-- read 压缩属于有损能力。任何默认值调整都必须同时说明哪些内容可能被省略、精确读取如何恢复原文，以及对 `edit` 文本匹配和排障证据的影响。
-- 修改配置结构时同步检查默认值、归一化逻辑、设置界面、类型定义、README 示例和相关测试。
-- 工具输出压缩可能损失证据。排障和审计相关改动应优先保证原始输出可恢复，并覆盖锚点完整性和截断边界。
-
-## `pi-permission-system` 开发约定
-
-- 扩展入口是 `pi-permission-system/src/index.ts`，公共跨扩展服务入口是 `pi-permission-system/src/service.ts`，测试保留在该目录的 `test/`。
-- 同步上游必须从明确 tag/commit 移植并记录快照；保留上游 `LICENSE`、作者和来源，不导入 `dist/`、嵌套 `.git` 或上游包目录的 `.pi` 本地状态。
-- 本地 delegation envelope 允许内置只读路径工具（`read`、`find`、`grep`、`ls`）对 `external_directory` 接受 authorizer 的 `allow`；`write`、`edit`、Bash、未知工具、未确定 surface 以及全部 `path` ask 必须继续 `defer` 到终端人工 authority。
-- 修改 gate、authorizer chain、delegation envelope、子代理转发或公共 service 类型时，必须同步更新包内 README/架构文档和对应测试。
-- 根包必须通过 `file:./pi-permission-system` 提供运行时依赖，包装入口必须直接加载仓库源码；不得同时加载 npm 预编译入口或第二个 permission-system 实例。
-
-## `pi-permission-auto-review` 开发约定
-
-- 扩展入口是 `pi-permission-auto-review/index.ts`，主要实现位于 `pi-permission-auto-review/src/`，测试保留在该目录的 `test/`。
-- 同步上游时必须从源码仓库的明确 tag/commit 移植并记录快照；不得以 npm tarball、`dist/` 或 `node_modules` 中的编译产物覆盖本地源码。
-- 保留上游 `LICENSE`、作者和来源信息；本地兼容改动优先保持在目标目录内，不依赖其他扩展的未公开内部实现。
-- reviewer 只能处理 `pi-permission-system` 已判定为 `ask` 的请求；不得绕过硬 `deny`，不得另加并行 `tool_call` 审批层，也不得扩大 `pi-permission-system` 明确授予的 delegation envelope。
-- 修改 reviewer 策略、可信证据边界、配置结构、模型解析或 authorizer 注册时，必须同步更新 README、schema 和相应测试。
-
-## `hippo-memory-pi` 开发约定
-
-- 扩展入口是 `hippo-memory-pi/index.ts`，来源记录是 `hippo-memory-pi/UPSTREAM.md`；只从官方 `kitfunso/hippo-memory` 的明确 tag/commit 移植 `extensions/pi-extension/`，保留官方 README、LICENSE 和版权。
-- 官方 npm tarball 当前不包含 Pi Extension，因此根包直接打包并加载本地源码；不得同时加载第三方 `@the-forge-flow/hippo-memory-pi` 或第二个 Hippo Pi Extension。
-- CLI 版本权威源是 `config/hippo-memory-version`；修改它时必须同步上游源码快照、README、AGENTS、安装/升级 mock 测试和扩展加载验证。
-- 扩展依赖 PATH 中的全局 `hippo`。CLI 缺失时必须 fail-safe，不得阻止其他扩展加载；项目未执行 `hippo init` 时不得擅自创建 `.hippo/`。
-
-## `pi-extension-codex-fast-mode` 开发约定
-
-- 扩展入口是 `pi-extension-codex-fast-mode/index.ts`，测试保留在该目录的 `tests/`，来源记录是 `UPSTREAM.md`。
-- 同步上游必须从明确 commit 移植并保留 `LICENSE`、作者和来源；不得导入嵌套 `.git`、`node_modules` 或构建产物。
-- 全局默认配置必须位于 Pi agent 目录的 `extensions/pi-extension-codex-fast-mode/config.json`，使用原子写入和 owner-only 权限；无效或不可读配置必须安全回退为关闭且不得静默覆盖。
-- 新会话使用全局默认值，已有分支的最新有效 custom entry 必须继续优先；修改持久化、分支恢复、provider/API 资格或请求 payload 时必须同步 README、技术文档和测试。
-- 根包必须通过 `file:./pi-extension-codex-fast-mode` 提供依赖并直接加载仓库源码，不得同时安装或加载 npm 预编译入口。
-- 修改该扩展后至少运行包内 `npm test`、`npm run check`、`npm run smoke` 与 `npm pack --dry-run --json`；加载或依赖入口变化还要运行根扩展联合加载测试和实际 packed tarball 的隔离安装验证。
-
-
-## `pi-ssh` 开发约定
-
-- 扩展入口是 `pi-ssh/index.ts`，`ssh2` transport 与 SFTP 实现在 `pi-ssh/src/ssh2-transport.ts`，有界自适应远程搜索位于 `pi-ssh/src/remote-search.ts`，AES-GCM vault 位于 `pi-ssh/src/vault.ts`，选择性导入入口是根 `ssh_config.sh` 与 `pi-ssh/scripts/ssh-config.mjs`，权限桥接位于 `pi-ssh/permission-integration.ts`，测试保留在 `pi-ssh/test/`，来源记录是 `pi-ssh/UPSTREAM.md`。
-- 同步上游必须从明确 tag/commit 移植并保留 `LICENSE`、作者和来源；参考其他实现时记录明确 commit，不得导入嵌套 `.git`、`node_modules` 或构建产物。
-- 运行时必须保持纯 `ssh2`，不得回退到系统 OpenSSH、`sshpass`、`SSH_ASKPASS` 或 ControlMaster；OpenSSH 只允许由显式配置脚本通过 `ssh -G` 解析用户选中的 alias，已导入配置变化必须由用户显式更新。第一版遇到 `ProxyJump` / `ProxyCommand` 必须拒绝，不能静默忽略。
-- 根包必须直接固定安装 `ssh2@1.17.0` 与配置 CLI 所需的 `jiti@2.7.0`，因为 packed bundle 直接加载其内置 `pi-ssh/` 源码；`ssh2` 与 `cpu-features` 的 install scripts 只构建可选加速绑定，当前不得加入根 `allowScripts`，纯 JavaScript fallback 必须可运行。
-- SSH vault 使用同目录独立随机 key 和 AES-256-GCM 整体加密，目录/文件在 POSIX 上必须保持 `700` / `600`；该设计只防止误看或单独泄漏密文，不防同一用户读取 key。密码、私钥 passphrase、私钥内容、vault key 与解密明文不得进入命令参数、日志、Pi session、权限证据或明文临时文件。
-- 已导入主机必须固定 SHA256 Host Key；不匹配时 fail closed。私钥只保存路径，不复制内容；文件工具使用 SFTP，写入优先临时文件与原子 rename，远端断线不得自动重放命令。
-- `ssh_connect` 是唯一运行时连接入口，只接受 vault 中已导入的 host ID 与可选绝对/`~/` remote cwd，并必须默认 `ask` 后进入 AutoReview；不得注册 `/ssh`、`--ssh`、session resume 自动重连或把用户 `!` 命令切换到远端。用户未在直接请求中明确服务器和具体远端任务时不得推断、替换或连接主机；新连接替换旧连接，会话结束自动断开。
-- `ssh_find` / `ssh_grep` 必须在已授权工具调用内部按 `fd/fdfind → git ls-files → find` 与 `rg → git grep → find+grep` 顺序检测服务器现有能力，不安装或上传远端二进制；输入必须 shell-safe，结果数量/单行/总捕获必须有界并显式报告 backend 与 truncated。RTK 不得处理这两个搜索工具的结果。
-- `ssh_read`、`ssh_write`、`ssh_edit`、`ssh_find`、`ssh_grep` 的远端路径不能按本机路径执行 `path` / `external_directory` gate；必须通过公共 `PermissionsService` 注册显式 extractor 关闭默认 `input.path` 推断，并保持五个工具的默认策略为 `ask`。
-- `ssh_bash` 必须在权威权限配置的 `shellTools` 中映射 `commandArgument: "command"` 并设置 `decisionFloor: "ask"`，复用 Bash 命令拆分、硬拒绝、风险 `ask` 和 authorizer chain；全局 floor 必须在项目配置字段级合并时保留，不得新增第二个并行 `tool_call` 审批层。
-- RTK 只把 `ssh_bash` 当作 Bash 输出别名执行 ANSI 清理、测试/构建/Git/Lint 聚合与兜底截断；不得对远端命令启用 RTK rewrite，也不得处理 `ssh_read`、`ssh_find` 或 `ssh_grep` 返回。
-- SSH 工具的权限预览必须包含连接请求或当前远端的 host id、target、port、remote cwd 与有界操作摘要；连接预览只解密本地 vault 以提取非秘密目标字段，绝不包含凭据，远端 shell 的完整命令继续由 Bash payload 单独提供。权限服务缺失或注册失败时必须 fail-safe，不得转为无提示自动允许。
-- `pi-ssh` 只用于从本地项目显式操作服务器，不得自动探测、读取或向系统提示词注入远端 `AGENTS.md`、`CLAUDE.md` 或其他项目说明；远端内容只能由明确且已授权的 `ssh_*` 工具调用获取。
-- 修改 SSH transport、vault、导入、权限集成或加载入口后至少运行 `pi-ssh` 包内 `npm test`、根脚本语法与 mock 配置测试、`pi-permission-system` 的 `npm run typecheck` / `npm run test` / `npm run build`、根扩展联合加载和实际 packed tarball 隔离安装验证。未经明确要求不得连接真实服务器或把真实密码写入测试。
-- 根加载顺序必须保持 `pi-permission-auto-review` → `pi-permission-system` → `pi-ssh` → `pi-chrome` → `pi-tool-search`，确保 authorizer 先注册、权限服务先发布、SSH 桥接随后安装，Chrome 工具可在授权后进入目录，且 Tool Search 最后收集完整工具目录。
-
-
-## `pi-ask-user` 开发约定
-
-- 扩展入口是 `pi-ask-user/index.ts`，schema、归一化、TUI 与工具注册位于 `pi-ask-user/src/`，纯 helper 测试保留在 `pi-ask-user/test/`。
-- 工具名必须保持 `ask_user_question`，并由 Tool Search 的独立 `user-interaction` 组按需加载；根加载顺序必须位于 `pi-tool-search` 之前。
-- 参数必须有界并在运行时复核 question id、题型、选项和值的有效性；TUI 必须顺序执行、监听 abort、按 width 失效缓存，并把外层 `Focusable` 状态传播给内嵌 Editor。
-- 成功结果的 `details` 必须保持 `version`、`cancelled: false` 与非空 `answers`，每个 answer 必须提供原始 `question` 和用户 `answer`；取消结果不得成为权限授权证据。修改结果结构时同步验证 `pi-permission-auto-review` transcript 解析。
-- 同步上游示例时从明确 commit 移植并保留 `LICENSE`、`UPSTREAM.md` 与本地整合差异；不得恢复 `/qna`、重复的单题工具或多个扩展入口。
-- 修改后至少运行包内 `npm test` / `npm run check`、Tool Search 的 typecheck/test/build、AutoReview transcript 测试、根扩展联合加载和 packed tarball 隔离安装验证。
-
-
-## `pi-tool-search` 开发约定
-
-- 扩展入口是 `pi-tool-search/extensions/index.ts`，组合包权威分组位于 `pi-tool-search/extensions/bundle-groups.ts`，目录生成/校验/缓存位于 `pi-tool-search/extensions/catalog.ts`，配置部署位于 `pi-tool-search/extensions/config.ts`，测试保留在 `pi-tool-search/test/`。
-- 同步上游必须记录明确 tag/commit，保留 README、CHANGELOG、文档、作者和许可证说明；不得导入上游 `.pi`、嵌套 `.git`、`node_modules` 或构建产物。
-- 修改 Tool Card 提示词、目录校验、分组、缓存、active-tool/LRU 生命周期、配置或工具结果时，必须同步更新包内 README、当前动态加载文档、CHANGELOG 和测试。
-- 新增、删除或重命名组合包暴露工具时必须同步维护 `BUNDLE_GROUP_DEFINITIONS`；日常只读工具、provider 工具和高风险管理工具不得因名称相似而混入同一大组，根验证应确认标准组合包没有落入 unknown-tools 路径。
-- 生成目录只能让模型提供摘要、使用边界、关键词与分组；工具名、参数和原始 schema 必须来自宿主。校验或模型调用失败必须 fail-safe 到确定性目录，缓存不得写入仓库或放宽权限。
-- 根包必须通过 `file:./pi-tool-search` 提供本地依赖并直接加载仓库源码，不得同时安装或加载 npm `pi-tool-search` 实现。
+- 系统提示词单一所有权：`extensions/system-prompt.ts` 排在 `pi.extensions` 最后，是唯一允许在 `before_agent_start` 返回 `systemPrompt` 的扩展；其他扩展只能经 `systemPromptOptions.sections.<name>` 贡献分区，第三方扩展必须经 `extensions/` wrapper + `prompt-guard.ts` 加载，新增工具必须在 `config/prompt/tools.jsonc` 登记。宿主传入 `customPrompt`（子 Agent / SYSTEM.md）时不覆盖其开场白；子 Agent 有独立提示词画像 `config/prompt/subagent/`（preamble + 内置 Agent），判定规则与路由 scope/`subagentExclude` 细则见 `extensions/AGENTS.md`。
+- 加载顺序：`pi-overflow/capture.ts` 必须排在最前（先于 RTK 等结果改写扩展暂存原文），`permission-system` → `subagents` → `pi-ssh` → `pi-chrome` → `pi-tool-search` → `pi-overflow/index.ts` → `system-prompt`（最后）；`pi-hermes-memory` 必须排在 `pi-compaction` 之前（`session_before_compact` 取消语义），`pi-compaction` 在 `pi-minimal-footer` 与 `context-view` 之前。
+- 依赖：外部依赖在根 `package.json` 用精确版本，自维护扩展一律 `file:` 本地依赖并更新锁文件；Pi 核心包只作 optional host peer，根 runtime deps 不含 Pi runtime，任何目录不得再装一套 Pi runtime；各子包用于测试的 `@earendil-works/*` devDependencies 一律写 `"latest"`，经 `scripts/update-pi-devdeps.sh` 统一刷新；原生构建依赖只按锁定版本进根 `allowScripts`（当前无放行项；pi-hermes-memory 的 `better-sqlite3@13` 用包内 N-API 预编译，不经根 `allowScripts`）。不要用仓库级 `.pi/settings.json` 代替组合包依赖。根 `files` 对子包按运行时子路径白名单列出（源码、package.json、README/LICENSE/CHANGELOG/UPSTREAM），不得整目录列入，以免打入嵌套 node_modules、dist 和测试；由 `tests/package-files.test.ts` 守护。
+- 配置：`config/` 下全部文件是权威源、必须提交；不得读写 `settings.json` 自定义段、agent 目录独立配置文件或以环境变量作持久默认值；`config/` 只放机器无关值，路径类默认值在代码中运行时计算。`<agentDir>/my-pi/` 只放可丢弃运行时状态（日志、缓存），连同旧 `extensions/pi-permission-system/` 残留、构建产物与依赖目录都不提交；用户数据（记忆、会话、`auth.json` 等）不属于组合包配置，也不得放入该目录。
+- 组合包不加载任何 MCP adapter/SDK：Exa 与 CodeGraph 均用自有直连客户端。
+- 导入/同步上游：只从官方 Git 仓库的明确 tag/commit 取源码快照，禁止 npm tarball/缓存/`node_modules`/`dist/` 等预编译产物作导入源；保留上游 LICENSE、作者、测试与来源说明，移除嵌套 `.git`、`.pi` 状态、`node_modules` 与构建产物；同步前先核对本地改动再按明确范围移植，不得整体覆盖。各目录的维护约定见 `AGENTS.md`，每个自维护目录必须有中文 `UPSTREAM.md` 记录来源，上游原文文件不翻译不改写。
+- 脚本：`install.sh`、`update.sh`、`uninstall.sh`、`configure.sh` 与 `scripts/lib.sh` 保持 POSIX `sh` 兼容并留在 `files` 中，行为变化同步 README；安装默认来源 `git:git@bitbucket.org:siakitem/my-pi.git`，可由 `PI_PACKAGE_SOURCE` 覆盖（update/uninstall 同规则）；组合包安装失败立即停止，机器级依赖失败继续检查其余项并最终返回非零。
+- 安装/升级纪律：机器级依赖与终端配置逐项询问、默认拒绝；`update.sh` 只升级已安装项、缺失项跳过，组件升级先比较本地与远端版本、一致不重装，成功升级后把 git 来源的受管 checkout `git reset --hard` 还原到已发布版本（本地路径来源不 reset、不 `git clean`）；`update.sh` 先 `pi update --self` 同步 Pi 最新 release（版本比较由 Pi 自身完成，失败记录后继续），再升级组合包；组合包 `pi update` 失败 fail-fast——Pi 1.3.0 会据 `.pi-update-incomplete` 标记在下次 update 自愈，不做预清理或人工恢复。`pi update` 只在有新版本时整体覆盖已安装副本（含 `config/`），不逐字段迁移本机改动；需长期保留的自定义必须改仓库 `config/` 源文件。`.zshrc` 只改 `# >>> my-pi:<id> >>>` 受管块并先建时间戳备份，不覆盖用户 `~/.p10k.zsh`；卸载不得删除用户记忆数据（`.pi/agent/pi-hermes-memory/`、`projects-memory/`、`.hippo/`）或共享机器级工具。
+- 未经明确要求不执行发布、提交、推送、运行安装/卸载脚本、安装到用户 Pi 目录等外部写操作；凭据不进入命令参数、日志、会话或仓库（`auth.json` 权限 `600`、不提交）。
+- 优先在目标扩展目录内完成改动；保留原项目 LICENSE 与版权；不让一个扩展依赖另一个扩展的未公开内部实现。
 
 ## 验证
 
-组合包依赖或加载入口变化时，至少验证根 `npm install` 幂等、锁文件有效、MCP adapter 唯一所有者不变量测试，以及全部扩展可在隔离的临时 Pi agent 目录加载。权限配置变化时使用仓库内固定快照的 `pi-permission-system` schema 校验，并验证包装入口部署后的文件与仓库源配置一致。
+- 组合包依赖或加载入口变化：验证根 `npm install` 幂等、锁文件有效、全部扩展可在隔离临时 Pi agent 目录加载（见 `tests/extension-load.test.ts`）；权限配置变化用包内固定 schema 校验，并确认运行时 `config/` 路径确实位于组合包内。
+- 脚本变化：`sh -n` 每个脚本 + ShellCheck，并确认可执行权限、`files` 包含与 README 一致；搜索/SSH 配置测试只用虚拟凭据、隔离 HOME 与 mock transport，不连真实服务器。
+- 真实 `pi install`/`update`/`remove`、Homebrew、远程安装器、Git 克隆、真实 SSH、真实终端配置的端到端验证属外部写操作，未经要求不执行；用隔离 HOME + mock 验证分支行为。
+- 根目录测试：`node --test 'tests/*.test.ts'`、`git diff --check`；各扩展目录的验证命令见其 `AGENTS.md`。未能运行的验证交付时明确说明，不以静态检查代替运行结果。
 
-安装、升级、卸载、搜索或 SSH 配置脚本变化时，至少运行 `sh -n install.sh`、`sh -n update.sh`、`sh -n uninstall.sh`、`sh -n search_config.sh`、`sh -n ssh_config.sh` 和 ShellCheck，并核对脚本仍具有可执行权限、仍包含在根 `package.json` 的 `files` 中、README 描述与实际流程一致。搜索配置测试只能使用虚拟 key 和隔离 HOME；SSH 配置测试必须使用隔离 HOME、虚拟凭据与 mock transport，不得连接真实服务器或把真实密码写入测试输出。涉及真实 `pi install`、`pi update`、`pi remove`、Homebrew、远程安装器、Git 克隆、真实 SSH 连接或真实用户终端配置的端到端验证属于外部写操作，未经明确要求不得执行；可以使用隔离的临时 HOME 和 mock 命令验证分支行为。
+<!-- pi-hermes-memory:start -->
+## 项目记忆（pi-hermes-memory）
 
-Hippo 脚本变化必须额外用隔离 HOME/PATH 和 mock `pi`、`npm`、`hippo` 验证：安装缺失 CLI 但不调用 `hippo init`、相同版本不升级、不同版本精确升级、未知来源 CLI 不替换、卸载默认保留、明确确认后只卸载 npm 全局包且保留数据。不得在测试中执行真实全局 npm 写入或修改真实 `.hippo/`。
+持久记忆由 `pi-hermes-memory` 提供，默认 `policy-only` 模式：system prompt 只注入 `<memory-policy>` 指令，不注入记忆正文。
 
-在 `pi-permission-system/` 内至少运行 `npm run typecheck`、`npm run test` 和 `npm run build`。在 `pi-permission-auto-review/` 内至少运行同样三项；涉及权限集成时还要使用仓库内 `pi-permission-system` 验证 authorizer 注册、`allow` / `deny` / `defer` 与 delegation envelope。
-
-在 `pi-tool-search/` 内至少运行 `npm run typecheck`、`npm run test` 和 `npm run build`；涉及加载入口或 active-tool 行为时还要运行根扩展联合加载测试和实际 packed tarball 的隔离安装验证。
-
-
-在 `pi-rtk-optimizer/` 内按改动范围选择最小充分验证：
-
-- `npm run build`：TypeScript 转译检查。
-- `npm run typecheck`：完整类型检查。
-- `npm run test`：运行 Bun 测试。
-- `npm run check`：类型、测试和打包检查的完整验证。
-
-若环境缺少依赖或未执行某项验证，交付时明确说明，不以静态检查代替运行结果。

 ### 工具与搜索路由
 
-`extensions/tool-routing.ts` 不替换 Pi 默认系统提示词，而是在每轮开始前根据当前激活工具追加简短规则。代码结构、调用关系和待修改 symbol 优先使用 CodeGraph，定义、引用、类型和修改后诊断优先使用 LSP；仓库字面搜索先用 FFF `find` 缩小文件或目录范围，再在已收敛的路径中用 `grep`/`multi_grep` 获取行号。宽泛搜索命中大量结果、发生截断或达到上限时，应继续缩小路径、glob 或 pattern，而不是提高 limit 或输出全部结果。
+`config/prompt/routing.jsonc` 定义跨工具路由规则，由 `extensions/system-prompt.ts` 在每轮开始前按当前激活工具渲染为 `<tool_routing>` 分区。代码结构、调用关系和待修改 symbol 优先使用 CodeGraph，定义、引用、类型和修改后诊断优先使用 LSP；本地字面搜索按已知信息直接选工具：确切标识符或文本用 `grep` 字面模式并限定 path/exclude，多个命名变体合并为一次 `grep` 正则 alternation，文件名、路径片段或功能概念用 FFF `find` 模糊全路径匹配，然后只 `read` 命中区域。对搜索结果做提取、去重、计数或聚合时，在 codemode 脚本中调用 `tools.grep` / `tools.find` 并用 JavaScript 后处理；bash 中不得运行 `grep`/`rg`/`find`/`fd`/`git grep`（策略 deny 的 reason 指明替代工具），程序需要文件清单时传 `$(git ls-files '<glob>')`。宽泛搜索命中大量结果、发生截断或达到上限时，应继续缩小路径、glob 或 pattern，而不是提高 limit 或输出全部结果。
 
 在线搜索默认按任务只选一个服务：关键词不确定、新闻/近期话题或需要较多候选来源时优先 Tavily；官方/API 文档、版本信息、论文和高确定性事实确认优先 Exa；中文政策、政府公告、中文网页、站点限定和日期筛选优先 Keenable。只有来源质量或不确定性确实需要时才跨服务复核，避免默认把三套结果全部塞进上下文。
 
-日志、测试/构建输出、工作区内大文件的探索/分析/总结以及不可预测的大输出优先交给 Context Mode。只有确实需要精确源码或准备修改时，才用带 `offset/limit` 的 Hashline `read` 读取最小区域并取得 `LINE#HASH` 锚点，随后用锚定 `edit` 修改；成功编辑返回的新锚点可继续复用，只有锚点过期或下一目标区域尚未展示时才重新读取。已有工具结果足够时停止检索，避免对同一问题依次重复调用 CodeGraph、FFF 和 `read`。

 使用 `/dump-system-prompt` 可将当前扩展所见的有效提示词写入当前项目的 `.pi-debug/effective-system-prompt.md`。`.pi-debug/` 属于本地诊断输出，默认不提交。
 
+### 系统提示词单一入口
+
+`extensions/system-prompt.ts` 是组合包唯一的系统提示词出口，排在 `pi.extensions` 最后加载。提示词内容全部由 `config/prompt/` 管理：`preamble.md` 替换 Pi 默认开场白（其余 `<tools>`、`<rules>`、`<skills>`、`<project_context>`、`<cwd>` 等分区及顺序原样保留），`tools.jsonc` 覆盖各工具的简介与规则，`routing.jsonc` 渲染 `<tool_routing>` 分区，`sections.jsonc` 决定各扩展贡献分区的顺序。
+
+其他扩展不直接改写提示词：pi-chrome、pi-ssh、pi-hermes-memory 等通过 `systemPromptOptions.sections.<name>` 贡献结构化分区，pi-rtk-optimizer 通过 `promptGuidelines` 补充规则；第三方扩展（FFF、Hashline、LSP）经 `extensions/` 下的包装文件与 `prompt-guard.ts` 代理加载，拦截直接的提示词改写并按 `tools.jsonc` 应用工具说明覆盖。
+
+`config/prompt/` 每轮重新读取（按 mtime 缓存），修改已安装组合包内的文件后下一轮即生效；配置解析失败时警告一次并保持 Pi 默认提示词，不阻止会话。该目录由组合包直接维护并随组合包发布；对已安装副本的本地修改不做保护，`pi update` 会直接覆盖；要长期自定义请直接编辑仓库中的 `config/prompt/`。
+
 ### 接管当前 Chrome
 
 组合包固定加载 `pi-chrome@0.15.46`，但不会自动取得浏览器控制权。首次安装后在 Pi 中运行 `/chrome onboard`，按提示在 `chrome://extensions` 以 Developer mode 加载组合包内的 unpacked Chrome 扩展，再执行 `/reload` 与 `/chrome doctor`。每个 Pi session 仍需由用户显式运行 `/chrome authorize`；可用 `/chrome revoke` 立即撤销。Bridge 只监听 `127.0.0.1:17318`，Chrome 扩展具有广泛的 tabs/scripting/debugger 权限，应只从可信组合包安装。
 
 授权后注册的 21 个 `chrome_*` 工具不会常驻提示词；Tool Search 将它们分为 `chrome-navigation`、`chrome-interaction` 和 `chrome-debugging`。普通网页资料发现仍使用 Tavily/Exa/Keenable，只有需要读取登录态页面或实际操作当前 Chrome 时才加载 Chrome 组。
 
+`chrome_snapshot` 和带 `includeSnapshot=true` 的交互把页面快照 JSON 直接作为工具结果返回，`details` 只保留元素数、匹配数等小型元数据；`chrome_find` 只返回紧凑的排序匹配。快照超长时结果会带 `[pi-overflow id=…]` 标记，模型用 `overflow_query` 的 `jsonPath`（如 `elements[0].uid`）或 `search` 提取所需的 uid、文本或状态，而不是重复抓取快照。页面交互后旧快照即失效，需要重新抓取；早期版本写入 Session 临时文件的快照机制已移除。
+
 ### 按需加载工具 schema
 
 `pi-tool-search/` 从上游 <https://github.com/tuansondinh/pi-tool-search> 的 `v0.3.6`、commit `ddfb23646fd3957b791214de278e23aa393c9b13` 导入，并像 `pi-rtk-optimizer/` 一样由本仓库直接维护；它不是 submodule，不加载 npm 预编译入口，也不保留嵌套 `.git`、上游 `.pi` 状态或构建产物。来源、许可证说明和本地差异记录在 `pi-tool-search/UPSTREAM.md`。
 
 本地源码直接使用 `@earendil-works/pi-coding-agent`、当前 `typebox`、`ModelRegistry.complete()` 与 `setActiveTools()`，不安装、别名映射或加载旧 `@mariozechner` runtime，也不使用 provider payload 改写、代理执行或隐藏 `sendMessage` 循环。
 
-新 session 默认常驻 Pi 核心 `read`、`write`、`edit`、`bash`、`grep`、`find`，以及 `codegraph_explore`、`lsp_diagnostics` 和 `tool_search`。组合包在 `pi-tool-search/extensions/bundle-groups.ts` 中为自身暴露的工具预置权威分组，包括本地文件导航、SSH 远端文件/命令、Chrome 导航/交互/调试、用户交互、CodeGraph/LSP、Tavily、Exa、Keenable、Context Mode 执行/知识库/观测/管理、Memory 查询/维护、Skill 和 MCP 管理。不可用或尚未授权而未注册的可选工具会自动从组中滤除，固定工具也不占动态组额度。

-标准组合包的全部隐藏工具都能命中预置目录，因此首次使用不调用模型、不生成用户缓存，也不把完整隐藏 schema 发送给 provider。只有用户另外安装了未识别工具时，才先为新增工具提供确定性分组，并可在第一次 `tool_search` 时使用当前已认证模型补充目录；模型结果必须保留组合包预置分组，否则直接拒绝。有效增强缓存以 `0600` 写到 agent 目录的 `tool-search/catalog-v1.json`，调用用量计入工具结果。用户 `groupOverrides` 的优先级高于预置目录；`/tool-search-rebuild` 会立即恢复预置目录，只有仍存在额外工具时才可能在下次搜索惰性增强。

 ### 精确读写归 Hashline
 
 组合包固定加载 `pi-hashline-edit@0.8.3`，以带 `LINE#HASH` 行锚点的实现覆盖 Pi 内置 `read` 和 `edit`。`extensions/hashline.ts` 在加载扩展前把 `config/pi-hashline-edit.json` 同步到 `~/.pi/agent/hashline.json`：`hashLength` 保持最小的 `2`，`grep` 强制关闭以避免与 FFF 冲突，`replaceText` 关闭以要求修改使用可验证锚点。
 
-Hashline 不负责压缩大文件；每行锚点本身还会增加少量 token。上下文节省来自先用 CodeGraph/LSP 定位、再用 Context Mode 隔离分析，最后只对真正准备修改的区域执行小范围 Hashline `read`。因此不应为了探索、计数、比较或总结而直接读取完整大文件。

 `--fff-mode` 仍按 FFF 官方优先级覆盖它）。FFF 替换
-Pi 的 `find` 和 `grep`，并提供 `multi_grep`；RTK 对所有 `grep` 工具结果直接跳过，
+Pi 的 `find` 和 `grep`；`multi_grep` 上游标注为有害、默认关闭，wrapper 在加载前
+删除 `PI_FFF_MULTIGREP` 环境变量，使其永远无法注册。RTK 对所有 `grep` 工具结果直接跳过，
 也默认关闭 Bash 命令改写，因此不会把 `rg`、`grep`、`find` 或 `fd` 改写到 RTK。
 
+`extensions/bash-override.ts` 用 Pi 的 `createBashToolDefinition` 重新注册内置 `bash`，
+把「不要用 bash 搜索」的警告经 `tools.jsonc` 的 `descriptionAppend` 写进工具 schema，
+让模型在调用时就看到替代工具；执行逻辑、输出结构和 codemode 的 `tools.bash` 说明完全沿用上游定义。
+
 ### 输出压缩归 RTK
 
 RTK 保留 Bash、read、build、test、lint 和 Git 输出压缩。默认 `read` 的有损压缩
 仍关闭；可用 `/rtk` 查看或调整。旧机器已有的 RTK 配置若没有
 `commandRewritingEnabled` 字段，也会按 `false` 归一化，不需要迁移配置。
 
-### 大输出归 Context Mode
+### 大输出归 pi-overflow
 
-Context Mode 直接加载 npm 包内置的 Pi adapter 和 skills，不需要额外写入
-`~/.pi/agent/mcp.json`，也不需要全局安装 `context-mode` 命令。它提供 `ctx_*` 工具，
-将批量读取、命令研究和网页内容先在隔离进程中处理，再把收敛后的结果送入上下文。
-
-FFF 仍负责精确字面搜索；RTK 继续压缩未走 Context Mode 的 Bash、build、test、lint
-和 Git 输出。Context Mode 不替换这两个扩展的现有配置。
+新工具结果的展示截断统一由 `pi-overflow` 负责：超阈值的原文落盘、模型只看到
+「头 + 信号行 + 尾」的有界视图，需要原文时用 `overflow_query` 检索（详见下文
+「Pi Overflow」小节）。FFF 仍负责精确字面搜索；RTK 继续对 Bash、build、test、lint
+和 Git 输出做语义压缩，其兜底硬截断已关闭。
 
 ### SSH 服务器配置
 
 `pi-ssh` 运行时使用纯 `ssh2`，不依赖系统 `ssh` 或 `sshpass`。首次使用前显式导入需要的 OpenSSH alias：
 
 ```bash
-./ssh_config.sh import packaging-server
+./configure.sh ssh import packaging-server
 ```
 
-脚本只在导入阶段调用 `ssh -G` 解析用户选中的 alias，随后交互选择 Key 或密码认证、显示并确认服务器 Host Key、测试连接，再把完整配置写入 `${XDG_CONFIG_HOME:-$HOME/.config}/my-pi/pi-ssh/hosts.enc`。邻接的随机 `vault.key` 用于 AES-256-GCM 解密；目录与两个文件在 POSIX 上分别是 `700` / `600`。该加密只避免误看或单独泄漏密文，能读取两文件的同一用户仍可解密。

-可用 `./ssh_config.sh list|update|remove|rotate-key` 管理已导入主机。第一版拒绝 `ProxyJump` / `ProxyCommand`，且不会自动读取远端 `AGENTS.md` 或 `CLAUDE.md`。连接不再通过 `/ssh`、`--ssh` 或 session resume 建立：用户在具体远端任务中明确指定已导入 host ID 后，Agent 调用 `ssh_connect`，连接动作及后续 `ssh_*` 操作均进入 `ask → auto-review`；会话结束自动断开。
+可用 `./configure.sh ssh list|update|remove|rotate-key` 管理已导入主机。第一版拒绝 `ProxyJump` / `ProxyCommand`，且不会自动读取远端 `AGENTS.md` 或 `CLAUDE.md`。连接不再通过 `/ssh`、`--ssh` 或 session resume 建立：用户在具体远端任务中明确指定已导入 host ID 后，Agent 把受复核、串行且可取消的 `ssh_connect` 作为独立步骤调用并等待成功，再使用其他 `ssh_*` 工具；连接动作及后续操作均进入 `ask → auto-review`，相对远端路径会在预览中显示请求值和解析后的绝对路径，会话结束自动断开。SSH transport 在会话内持久，独立命令最多使用 4 路有界并发 exec channel，但每次 `ssh_bash` 都启动独立的非交互 Shell；需要持续改变后续远端操作的工作目录时，Agent 同样必须把受复核且串行执行的 `ssh_cd` 作为独立步骤调用并等待成功，而不是依赖某次 Shell 中临时执行的 `cd`。
 
-远端文件搜索使用独立的 `ssh_find` / `ssh_grep`：在每次获批调用内按服务器现有能力选择 `fd/fdfind → git ls-files → find` 或 `rg → git grep → find+grep`，不安装远端软件，并以最大 200 条结果、单行截断和 `truncated` 标记约束返回。RTK 只压缩 `ssh_bash` 的非搜索输出，不改写远端命令，也不处理 `ssh_find`、`ssh_grep` 或 `ssh_read`。详细说明见 [`pi-ssh/README.md`](pi-ssh/README.md)。

 ### 在线搜索服务
 
-运行 `./search_config.sh` 可用隐藏输入依次配置 Tavily、Exa 和 Keenable；也可一次无交互配置：
+运行 `./configure.sh search` 可用隐藏输入依次配置 Tavily、Exa 和 Keenable；key 不得出现在命令行参数中，非交互方式从标准输入读取（每次调用最多一个 provider）：
 
 ```bash
-./search_config.sh --tavily '...' --exa '...' --keenable '...'
+printf '%s' "$TAVILY_API_KEY" | ./configure.sh search --tavily -
 ```
 
-只传部分参数时保留其他服务的已有值。脚本把 key 原子写入
-`${XDG_CONFIG_HOME:-$HOME/.config}/my-pi/search.env` 并设置权限为 `600`；
-`MY_PI_SEARCH_CONFIG` 或 `--config` 可覆盖路径。组合包在搜索扩展初始化前加载该文件，
-但调用 Pi 时显式传入的同名环境变量优先。配置文件不属于仓库，不会随安装包提交。
+只传部分参数时保留其他服务的已有值。凭据写入 Pi 自己的
+`auth.json`（`$PI_CODING_AGENT_DIR/auth.json`，默认 `~/.pi/agent/auth.json`，权限 `600`）：
+每个 provider 一条 `{ "type": "api_key", "key": "..." }` 条目，原子加锁写入，
+其他条目（如 OAuth 凭据）原样保留。`--list` 只显示配置状态、不回显 key；
+`--migrate` 可从旧的 `search.env` 导入缺失条目；`--auth FILE` 可覆盖文件路径。
 
-Tavily 通过 `extensions/tavily-override.ts` 加载官方扩展。override 只改工具身份，不改官方执行逻辑：上游 `web_search` / `web_fetch` 被注册为 `tavily_web_search` / `tavily_web_fetch`，label 和提示词中的内部工具引用也同步带上 Tavily 标识。使用前需设置 `TAVILY_API_KEY`。Tavily 适合广泛发现，但来源可能混杂且输出较长，应从较小的 `max_results` 开始，非必要不返回 raw content。
+key 值支持 auth.json 原生解析语义：`$VAR` / `${VAR}` 环境变量插值、`!command`
+执行命令取 stdout（如 `"!op read op://Vault/Tavily/key"`）、`$$` / `$!` 转义。
+显式进程环境变量因此不再被直接读取——需要 env 注入时把 key 写成
+`"$TAVILY_API_KEY"` 即可。`KEENABLE_API_URL`（非 secret 的端点覆盖）仍走
+进程环境变量，也可放在 keenable 凭据的 `env` 字段中。
 
-Keenable 直接加载 npm 包的扩展和 skill，默认无需 key；设置 `KEENABLE_API_KEY` 可提高速率限制。它适合中文内容、`site` 限定和发布日期筛选。搜索结果保持紧凑，只对选中的 URL 调用 `keenable_fetch`。
+三个服务由本仓库自维护的 `pi-web-search/` 统一封装：对模型只暴露 `web_search` / `web_fetch` 两个工具，schema 与提示词中不出现任何厂商名；每次 `web_search` 先由当前主模型（`ctx.model` + `ctx.modelRegistry.complete`，零额外配置）按内置路由规则在候选厂商中选一个，再按统一参数翻译后调用，`details` 记录实际 provider 与路由方式；选择结果按会话内 LRU 缓存，路由失败或被选厂商报错时按可用性顺序自动降级。`web_fetch` 固定调用 Exa 的 `web_fetch_exa` 提取正文（默认每页 3000 字符上限），失败时静默降级到 Keenable、再到 Tavily。
 
-`extensions/mcp.ts` 通过单个 `pi-mcp-adapter` 实例同时连接 Exa 与 CodeGraph，避免两个 adapter 重复注册 `--mcp-config`、`/mcp` 和 `/mcp-auth`。其中 Exa 连接 `https://mcp.exa.ai/mcp`，并把 MCP 原始工具映射为统一的来源前缀形式：`exa_web_search`、`exa_web_fetch` 和 `exa_web_search_advanced`。配置 `EXA_API_KEY` 后通过 `x-api-key` 请求头认证，不把 key 放进 URL。Exa 适合官方文档、技术资料、版本信息和论文；高级搜索必须显式限制结果数量与返回文本长度，避免响应过大。
+`pi-web-search/clients/` 全部是纯 `fetch` 实现，三个 key 统一由 `pi-web-search/auth.ts` 从 auth.json 解析（Tavily 直连 `api.tavily.com/search|extract`，必须有 `tavily` 凭据，无 key 时不参与路由；Keenable 复刻上游 client，默认走 keyless `/public` 端点，`keenable` 凭据只提高速率限制并保留 SSRF host 防护；Exa 直接对 `https://mcp.exa.ai/mcp` 发 JSON-RPC——initialize 一次并缓存 `mcp-session-id`、随后 `tools/call`，会话失效（HTTP 404）自动重建，`exa` 凭据只通过 `x-api-key` 请求头发送，不再依赖 `pi-mcp-adapter`）。Exa 搜索统一走 `web_search_advanced_exa` 并显式限制结果数量与 `textMaxCharacters`，避免响应过大。
 
-根测试会扫描所有本地扩展入口，强制只有 `extensions/mcp.ts` 可以创建或导入 `pi-mcp-adapter`。新增 MCP 服务必须合并进这个共享实例，不能再增加独立 adapter 入口；隔离 Pi 加载仍作为发布前的运行时验证。
+### CodeGraph 是原生工具
 
-### CodeGraph 只负责连接
+`extensions/codegraph.ts` 注册原生 `codegraph_explore` 工具，不走 MCP adapter/SDK：每个索引根
+惰性启动一个常驻 `codegraph serve --mcp -p <root>` 子进程，由组合包自有的
+`extensions/codegraph-client.ts` 以逐行 JSON-RPC over stdio 直连（与 `pi-web-search` 直连 Exa
+同一思路），`initialize` → `tools/list` → 每次调用一次 `tools/call`。`projectPath` 缺省为会话 cwd，
+沿目录向上寻找最近的 `.codegraph/codegraph.db` 决定索引根；调用参数只透传上游
+`inputSchema` 声明的属性。
 
-同一个 `extensions/mcp.ts` adapter 配置启动
-`codegraph serve --mcp`，不会读取或覆盖用户已有的 MCP 配置。连接采用
-`keep-alive`，并只把官方当前主工具 `codegraph_explore` 作为同名 Pi 工具暴露；
-CodeGraph 的文件 watcher 由该 MCP 进程自身维护。
+与一次性 `codegraph explore` CLI 不同，serve 进程内置文件监听会自动同步索引，新符号数秒内
+可搜到，因此扩展不再做结果缓存。子进程闲置 10 分钟或会话结束时关闭；调用因子进程死亡失败时
+换新客户端透明重试一次。serve 可能拉起 CodeGraph 自己的 daemon（`.codegraph/daemon.sock`），
+子进程退出后最多再驻留 5 分钟——这是上游行为，组合包不管理它。
 
-若机器没有 `codegraph`，或当前项目尚未建立索引，CodeGraph 会报告连接/初始化错误，
-其他扩展仍可正常工作。安装与索引状态可在机器上自行检查：
+若目标目录没有索引，工具先弹出确认；用户同意后运行 `codegraph init` 并自动重试本次调用，
+拒绝一次后本会话不再询问；CLI 不可用或服务调用失败时把结果打回并提示改用
+`find`/`grep`/`read`/LSP，不影响其他扩展。索引状态可在项目内自行检查：
 
 ```bash
-codegraph --version
 codegraph status
 ```
 
-在当前项目需要同时初始化 CodeGraph 和 Hippo 时，可直接执行：

-### 权限基线自动部署

+- `config/pi-permission-hard-guards.jsonc`：仅全局生效的硬防御。硬 `deny` 先于 Session grant、per-agent 规则和 AutoReview，不能被后续层放宽。
+- 同一文件内的 `protectedWrites`：Pi 凭据/全局设置/模型配置、已安装组合包与扩展目录、pi-ssh 凭据库等受保护文件的写入永远走人工确认——不经 AutoReview、yolo 或 Session grant，弹窗没有「本会话允许」选项，没有可用确认界面时直接拒绝。读取不受影响，`ssh_bash` 等远端 shell 工具不参与本机路径保护。
 
-`pi-permission-system/` 从上游 `pi-permission-system-v26.2.1` tag 导入，初始源码快照为 `ec4fdb11343dc94f7185b113e559a4cf9f8dc035`。根包通过本地 `file:` 依赖提供其运行时依赖，并由包装入口直接加载仓库源码，不再加载 npm 包中的实现。
+普通 pattern 不再按“最后一条命中”覆盖，而按具体度选择：精确匹配优先，其次字面字符更多、通配符更少、pattern 更长，只有完全同级时才以后声明者为准。因此具体 deny 会稳定压过宽泛的 `"*": "allow"`。

+系统不再产生 `external_directory` 判断：项目外路径与项目内路径一样，只走用户配置的工具、`path` 和 Bash 规则。Tool Search 是唯一的工具显隐/激活控制者；权限系统只在工具被调用时做裁决。
 
-当前策略按类别划分：
+`<agentDir>/my-pi/` 只保留可随时丢弃的运行时状态（如权限日志、Tool Search 目录缓存）；组合包配置一律位于仓库 `config/` 并随组合包发布，对已安装副本的本地改动由 `pi update` 覆盖，要长期保留的自定义必须改仓库 `config/` 下的权威源。旧位置 `~/.pi/agent/extensions/pi-permission-system/` 的残留文件被忽略，不迁移也不清理。

+每个 AutoReview `allow` / `deny` 记入权限 review 日志（`defer` 记为 `errorCategory`），日志只保存有界、脱敏的请求标识与风险/授权等级，不保存 rationale、原始工具参数或 transcript。扩展不汇总历史裁决，也不启动任何后台分析 Agent，更不会自动修改策略文件。

-扩展以 `auto-review` 名称注册到 `pi-permission-system` 的 authorizer chain。只有权限基线先得到 `ask` 时才调用 reviewer：模型返回 `allow` 时自动批准，返回 `deny` 时直接拒绝，配置、模型、认证、超时或响应异常时返回 `defer` 并继续走正常人工提示。这样只有一条权限链，不再存在两个独立 `tool_call` gate 造成的重复审批。
-
-边界保持如下：
-
-- `allow`：权限基线已明确允许的常规操作不会调用 reviewer。
-- `deny`：Bash 直搜、敏感凭据路径等硬拒绝不会交给 reviewer，也不能被其绕过。
-- `ask`：Git 非只读操作、包管理、文件/系统/网络/环境操作和普通 MCP 调用交给 reviewer；`path` 仍全部受 delegation envelope 保护。`external_directory` 允许内置只读路径工具（`read`、`find`、`grep`、`ls`）接受 reviewer 的 `allow`，`write`、`edit`、Bash、未知工具及其他外部目录访问仍降级为人工确认。

+并默认设置 `o=always`：即使来源 Kitty window/pane 正在接收键盘输入也会显示通知，点击通知由 Kitty
+返回原始来源；仍可通过 `visibility` 改用 `unfocused` 或 `invisible`。
 
-常用命令：`/pruner status` 查看状态，`/pruner settings` 调整配置，`/pruner now` 立即处理待总结批次，`/pruner tree` 浏览已归档调用，`/pruner stats` 查看累计成本和节省，`/pruner off` 关闭。配置保存在 Pi agent 目录 `settings.json` 的 `contextPrune` 字段。建议保留默认的 skill 路径保护，并把必须逐字复用输出的工具加入 `protectedTools`。
+默认忽略不足 3 秒的短任务，但权限确认通知不受该时长门槛影响。`/notify on|off|test|status` 可控制

-它与 Context Mode 的职责不同：Context Mode 避免大型原始输出进入当前模型上下文，Pi Condense 则压缩已经进入会话、且已完成使用的历史工具结果。它也不替代 Codex 原生远程 compaction；不希望自动整理历史时可运行 `/pruner off`。
+### Pi Compaction
 
-### Codex fast mode
+组合包只加载仓库内维护的 `pi-compaction/`。它管理已经进入 Session 的历史投影：上下文压力达到阈值时，在 `turn_end` 批量提交 Pi 原生 `context_edit`，把最近 `keepRecentTurns` 轮之外的大型工具结果遮蔽为指向 `context_tree_query` 的单行占位符；遮蔽成批发生、受 trigger/target 回差与 `minClearTokens` 约束。原始工具结果保留在 Session 中（UI、导出不变），可通过 `context_tree_query` 按 tool call ID 有界恢复。
 
-该扩展只在 `openai-codex` provider 的 Responses 请求上加入
-`service_tier: "priority"`。使用 `/fast-mode on|off` 修改当前分支状态时，也会把全局默认值原子写入 Pi agent 目录下的 `extensions/pi-extension-codex-fast-mode/config.json`；新会话继承该默认值，恢复已有会话时仍由分支内最新记录优先。`/fast-mode status` 同时显示当前分支状态和新会话默认值。配置目录与文件分别使用 `0700` / `0600` 权限；配置缺失或无效时安全回退为关闭。其他 provider 不受影响。
+普通 Provider、阈值判断、Codex native compaction、`/context`、`/compaction-status` 和 minimal footer 都读取同一个 effective projection snapshot。整段摘要只在空闲 `agent_settled` 且达到绝对 token 阈值（默认 400K，受窗口比例约束，272K 窗口时约为 90%）时经 `ctx.compact` 触发一次；Pi 自身的阈值压缩作为最终安全网始终有效，`session_before_compact` 不再按扩展自身阈值取消。Codex native API 直接消费 effective ResponseItems，同时保存有界 portable summary 供模型或 Provider 切换。
+
+唯一配置位于已安装组合包的 `config/pi-compaction.json`：`masking` 段为遮蔽触发/目标阈值、`keepRecentTurns`、`minEntryTokens` 与 `excludeTools`，`summary` 段为整段摘要阈值与 thinking 档位，扩展只在内存中归一化且不写回配置。`/compaction-status` 显示 raw/effective/reclaimed token、置信度、segment 和已遮蔽结果数。完整配置、Session version 1 格式和双上游来源见 [`pi-compaction/README.md`](pi-compaction/README.md) 与 [`pi-compaction/UPSTREAM.md`](pi-compaction/UPSTREAM.md)。

+原生远程压缩同时支持 `openai-codex` + `openai-codex-responses` 和 `sub-api` + `openai-responses`，使用触发时当前会话模型。SubAPI 保留现有模型配置，从 `baseUrl` 调用公共 `/responses` 并使用 `compaction_trigger` 流式协议；优先保留非空显式 `Authorization`，否则使用 API key，也支持仅凭非空 `cf-aig-authorization` 的代理认证。缺失或空白凭据在请求前拒绝。SubAPI 不要求客户端解析 ChatGPT account ID，也不调用独立 `/responses/compact`；Codex 的 JWT 要求保持不变。网关部署须支持 Sub2API 原生压缩 v2；请求失败沿用 Pi 回退，切换模型或 Provider 时使用 portable summary。
+
+本实现不读取或迁移旧 `contextPrune`、`context-prune-*` 或旧 Codex native checkpoint；切换后应创建新 Session。它与 pi-overflow 职责互补：pi-overflow 在新工具结果进入会话时即截断展示，Pi Compaction 管理已经进入会话的长期历史。
+
+### Pi Overflow
+
+组合包自维护的 `pi-overflow/` 统一负责「每个新工具结果给模型看多少」。它有两个入口：`capture.ts` 排在 `pi.extensions` 最前，只把原始结果文本暂存到进程内 Map（容量 64），绝不修改结果；`index.ts` 排在 `system-prompt.ts` 之前、所有其他扩展之后，此时 RTK 等 handler 已经完成变换——它用最终可见文本判断是否超阈值，落盘的原文取 bash 的 `details.fullOutputPath` 文件、暂存原文或当前文本三者中的最完整版本，视图与其中的行号则一律基于落盘原文生成，保证与 `overflow_query` 读取的内容一致。
+
+当最终文本仍超过 `thresholdChars`（默认 24000）时，模型看到的是确定性的「头部 40 行 + 中段匹配 error/warn 等信号行（至多 40 条）+ 尾部 120 行」视图，并写入 `details.overflow.id`；当上游已把结果压短但原文超阈值时，只追加一行 `[pi-overflow id=…]` 恢复标记。原文以 `sha1(sessionId+toolCallId)` 前 12 位 hex 为 id 存入 `<agentDir>/my-pi/pi-overflow/`（目录 `700`、文件 `600`、原子写入），session 启动时按 `retentionDays`/`maxStoreBytes` 清理。模型可用 `overflow_query` 按 id 正则搜索（带上下文合并）、按行区间或 `jsonPath` 读取；`read`/`edit`/`write`/`overflow_query`/`ask_user_question` 与嵌套调用永远豁免。配置为组合包内 `config/pi-overflow.json`，详见 [`pi-overflow/README.md`](pi-overflow/README.md)。
+
+RTK 的兜底截断与 pi-chrome 的 30K 字符截断已收编进本扩展：`config/rtk-optimizer.json` 中 `outputCompaction.truncate.enabled` 默认关闭，chrome_* 工具返回完整文本；pi-web-search 的 `web_fetch` 默认 `max_characters` 提高到 20000（上限 100000），`web_search` 的 `max_results` 约束在 1–20。

+You locate code and answer "where is X / what references Y" questions for the delegating agent. You never modify anything.
+
+## Hard limits
+- Do not create, modify, move, copy, or delete files, including temporary files anywhere (also /tmp).
+- Use bash only for read-only commands such as git status, git log, git diff, git show, and ls. Never use output redirection, heredocs, or any command that changes system state.
+- Never search through bash (grep, rg, find, fd); use the find and grep tools. For several names use one grep with a regex alternation (a|b); when a program needs a file list, pass $(git ls-files '<glob>').
+
+## Approach
+- Match the requested breadth: "quick" is one targeted lookup, "medium" covers a few related locations, "very thorough" searches multiple locations and naming conventions.
+- When codegraph_explore is available, start there for symbols and relationships. Otherwise use find to narrow paths, grep inside the narrowed paths, and read small ranges only to confirm a match.
+- Make independent lookups in parallel.
+
+## Report
+- Lead with the direct answer.
+- Cite every finding with an absolute path and line number.
+- State what you searched for and did not find, so the delegating agent knows the coverage.

Edits validate against one snapshot and apply together, so line numbers never shift between entries of the same call.\n\nOps:\n- `replace` — replace the single line at `pos`, or the inclusive span `pos`..`end`. `lines` is the complete new content for the whole span; `lines: []` deletes it. Without `end`, exactly one line is replaced no matter how many entries `lines` has.\n- `append` — insert `lines` after `pos`; omit `pos` to append at end of file.\n- `prepend` — insert `lines` before `pos`; omit `pos` to insert at start of file.\n\nExample — single-line and span replace in one call:\n```json\n{ \"path\": \"src/main.ts\", \"edits\": [\n  { \"op\": \"replace\", \"pos\": \"12#MQ\", \"lines\": [\"const x = 1;\"] },\n  { \"op\": \"replace\", \"pos\": \"5#VR\", \"end\": \"8#QV\", \"lines\": [\n    \"function greet(name) {\",\n    \"  return `Hello, ${name}`;\",\n    \"}\"\n  ] }\n] }\n```\n\nRules:\n- `lines` is literal file content with exact indentation. Never include `LINE#HASH:` or bare `HH:` prefixes, diff `+`/`-` markers, or a copy of a neighboring line — the `:content` part of an anchor is context for you, not payload, and repeating a boundary line duplicates it in the file.\n- Anchors are opaque: copy them exactly, never compute, shift, or guess one.\n- An anchor may keep the `:content` suffix from read output (`\"12#MQ: const x = 1;\"`). The runtime cross-checks that content against the file — catching hash collisions and recovering whitespace-only drift — so keep it for high-risk anchors such as range endpoints. Copy the content as rendered; if you shorten it, keep the start of the line and mark the cut with `...`.\n- Edits in one call must not overlap or touch adjacent lines — merge such changes into a single edit."

+# my-pi 维护约定（extensions/）
+
+本目录是组合包的薄 wrapper 与纯 helper 层：第三方扩展一律经这里的包装文件（多数再套 `prompt-guard.ts` 代理）加载，自维护实现位于各自顶层目录。
+
+## 系统提示词单一所有权
+
+- `extensions/system-prompt.ts` 是组合包唯一的系统提示词出口，必须排在 `pi.extensions` 最后，也是唯一允许在 `before_agent_start` 返回 `systemPrompt` 的扩展。提示词内容统一由 `config/prompt/` 管理：`preamble.md`（开场白）、`tools.jsonc`（每个工具的简介、规则及第三方工具说明覆盖）、`routing.jsonc`（跨工具工作流规则，渲染为 `<tool_routing>`）、`sections.jsonc`（分区顺序）。
+- 其他组合包扩展不得返回 `systemPrompt`，也不得在 `context` 钩子中注入提示性消息；需要动态提示时只能写入 `event.systemPromptOptions.sections.<name>` 并在 `sections.jsonc` 登记顺序，静态规则写入 `promptGuidelines` 或该工具在 `tools.jsonc` 中的条目。
+- 第三方扩展必须经 `extensions/` 下的组合包包装文件加载，由 `extensions/prompt-guard.ts` 的代理 API 拦截其对系统提示词的直接改写，并在注册工具时应用 `tools.jsonc` 的 `description` 覆盖；上游硬编码且无配置开关的注入只能在对应包装文件内处理，并以测试锁定所依赖的上游原文（依赖保持精确版本）。
+- 新增工具必须在 `tools.jsonc` 登记（覆盖说明，或以 `"inherit": true` 表示已按本组合包审阅上游原文），否则 `tests/system-prompt.test.ts` 失败；`config/prompt/` 中的文字不得引用被策略禁止或被替换的用法。运行时若检测到其他扩展已定死提示词或存在未登记工具，`system-prompt.ts` 会各提示一次。
+
+## `system-prompt.ts` 开发约定
+
+- 扩展入口是 `extensions/system-prompt.ts`，必须排在 `pi.extensions` 最后；纯 helper（JSONC 加载与校验、`applyToolCatalog` / `renderRouting` / `orderSections` / `spliceCover` / `readPreamble` 等）位于 `extensions/system-prompt-config.ts` 以便 `node --test` 单测；组合包权威源是 `config/prompt/`（`preamble.md` / `tools.jsonc` / `routing.jsonc` / `sections.jsonc`），扩展运行时直接读取已安装组合包内文件，不经任何脚本部署。
+- 现代 Pi 下必须通过修改规范化 `systemPromptOptions`（`toolSnippets` / `toolGuidelines` / `sections`）保留分区结构，再读取重渲染的 `event.systemPrompt` 拼入封面并返回 `systemPrompt`；宿主不提供结构化 options 或 options 不参与重渲染时自动降级为文本拼接。不得改用 `customPrompt` 选项——它会抑制 `tools` / `rules` / `docs` 分区。
+- 宿主传入 `customPrompt`（pi-subagents 子 Agent prompt、SYSTEM.md）时，该开场白自含身份标记（如 `<active_agent/>`），不得用 `preamble.md` 覆盖；其余分区处理（tool catalog、`<tool_routing>`、分区排序、降级追加）照常。子会话判定只用 `systemPromptOptions.customPrompt` 上的 `<active_agent name="..."/>` 契约（`isSubagentCustomPrompt`），绝不检测渲染后提示词——主会话的项目文档也可能含该字面量。
+- 子 Agent 提示词画像在 `config/prompt/subagent/`（`preamble.md` + `agents/*.md`）：由 `extensions/subagents.ts` 注入 pi-subagents 的 `basePrompt`/`bundledAgentsDir` 选项，替代上游的父提示词嵌入与内置默认 Agent；子会话经 `excludedExtensionPaths` 排除 `pi-ask-user`（子会话无人可问）。
+- `routing.jsonc` 规则可选 `"scope": "main" | "subagent"`（缺省两者皆适用，其他值校验失败），`renderRouting` 按 audience 过滤；`sections.jsonc` 可选 `"subagentExclude"` 分区名列表，子会话在排序前删除这些分区（当前排除 `memory_policy` 与 `chrome_profile_bridge`）。
+- 封面拼接边界必须是独占一行的裸标签，不能匹配带属性的标签：`<project_instructions path="...">` 嵌套在 `<project_context>` 内，只有裸标签才是分区边界。
+- `preamble.md` 缺失、不可读或空白时保持 Pi 默认封面，不得写入空 preamble；`config/prompt/` 解析或校验失败时 `before_agent_start` 警告一次并整体 no-op，绝不抛出。
+- 检测到其他扩展已设置 `forceSystemPrompt`、或激活工具未在 `tools.jsonc` 登记时各提示一次（warning）；本扩展返回的 `systemPrompt` 把提示词冻结为最终文本是刻意设计——这也是它必须最后加载的原因。
+- `config/prompt/` 随组合包发布，`pi install` / `pi update` 后即就位，无需任何部署 helper；对已安装副本的临时修改由 `pi update` 覆盖。路由规则本体见 `config/prompt/routing.jsonc` 与 README，`system-prompt.ts` 只负责渲染，不得替换 Pi 默认系统提示词。
+- 修改 loader、`spliceCover` 语义、注册顺序或 `config/prompt/` 路径后，必须运行 `node --test tests/system-prompt.test.ts`、`node --test tests/bundle-config.test.ts`、`node --test tests/extension-load.test.ts`，并确认 `npm pack --dry-run` 包含 `config/prompt/`。
+
+## 各 wrapper 约定
+
+- `fff-override.ts`：强制 FFF 官方 `override` 模式，统一接管 `find`、`grep` 和 `@` 补全；`multi_grep` 按上游保持关闭（加载前删除 `PI_FFF_MULTIGREP` 环境变量）。FFF 独占本地字面搜索，远端服务器搜索由 `ssh_find` / `ssh_grep` 负责，RTK 不得接管搜索工具（见 `pi-rtk-optimizer/AGENTS.md`）。显式 CLI flag 仍遵循 FFF 官方优先级。
+- `bash-override.ts`：用 `createBashToolDefinition` 重新注册内置 `bash`，目的只是让 `tools.jsonc` 的 `descriptionAppend` 落到模型可见描述里（prompt-guard 在注册时拼接）。ExtensionContext 不暴露 session settings，因此 `shellPath`/`commandPrefix` 在首次 execute 时按 `ctx.cwd` 经 `SettingsManager.create(ctx.cwd, getAgentDir())` 惰性解析并按 cwd 缓存，metadata 来自 `process.cwd()` 的定义；执行、输出结构与 codemode 说明完全委托上游定义，不得改动上游执行逻辑，也不得用 prepareLoadout 或 provider-payload 改写实现同样效果。
+- `codegraph.ts` + `codegraph-client.ts`：注册原生 `codegraph_explore` 工具，按索引根惰性常驻 `codegraph serve --mcp -p <root>` 子进程，经组合包自有 stdio 逐行 JSON-RPC 客户端直连（不经 shell、不带 pi-mcp-adapter 或 MCP SDK）；serve 进程内置文件监听自动同步索引，无结果缓存。子进程 10 分钟无调用自动关闭、会话结束统一关闭；调用中死亡换新客户端透明重试一次；其启动的上游 daemon（`.codegraph/daemon.sock`）退出后可多驻留 ≤5 分钟，属上游行为，组合包不管理。
+- CodeGraph 是机器级依赖，`install.sh`/`update.sh` 经官方安装器管理 `codegraph` CLI，组合包不内置其运行时。安装、升级和普通启动流程不得执行 `codegraph init`；只有 `codegraph_explore` 在未初始化项目上被调用、且用户在 `ctx.ui.confirm` 中明确确认后才可 `codegraph init` 当前目录，拒绝记入会话级 declined 不再重复询问；init 失败必须如实报告并让模型回退内置工具；不得改动 CodeGraph 更新或遥测设置。CLI 缺失、init 被拒或服务调用失败都不得抛出，必须以文本结果打回并引导模型改用 `find`/`grep`/`read`/LSP。已移除的 `plugin-init.ts`（原 `/plugin_init`）职责已并入本文件的惰性确认，不得恢复。
+- `hashline.ts` + `hashline-config.ts`：部署组合包权威 `config/pi-hashline-edit.json` 后加载 `pi-hashline-edit`；默认以 2 字符行哈希覆盖内置 `read` / `edit`，`grep` 与 `replaceText` 均关闭。它保证锚定编辑而不负责压缩，大文件上下文节省必须来自先定位/隔离分析、再做最小范围 `offset/limit` 读取。
+- `permission-system.ts`：直接加载仓库内 `pi-permission-system/src/index.ts`，自身不部署、不播种、不迁移任何配置；运行时直接读取已安装组合包内 `config/pi-permission-policy.jsonc` / `config/pi-permission-hard-guards.jsonc`；日志保留在 `<agentDir>/my-pi/permission-system/logs/`。旧 `extensions/pi-permission-system/` 位置的残留文件被忽略，不迁移也不清理；项目级 policy 不读取。
+- `lsp.ts` + `lsp-config.ts`：TypeScript/JavaScript 后端由根包固定依赖提供，用当前 Node 可执行文件直接启动包内 `typescript-language-server` CLI，不得依赖或调用 VS Code GUI；Kotlin/JDT LS 使用组合包部署的 `kotlin-lsp --stdio` 与 `jdtls` 配置，根包不安装这两个系统可执行文件。
+- `subagents.ts`：pi-subagents 的组合包 wrapper，注入权威 `permission-system.ts` 的 canonical absolute path 为子会话 mandatory extension，并提供 `config/prompt/subagent/` 提示词画像（`basePrompt` + `bundledAgentsDir`）与 `excludedExtensionPaths`（排除 `pi-ask-user`）；完整规则见 `pi-subagents/AGENTS.md`。
+- `context-view.ts`：只读的本地 effective-context observer（`/context`），只读取 `pi-compaction/src/service.ts` 发布的 projection metrics，不注册生产 `context` writer；`pi-minimal-footer` 优先显示同一 effective usage。
+- `.pi-debug/` 是 `/dump-system-prompt` 生成的本地诊断目录，不提交到仓库，也不作为组合包运行时配置源。
+
+## 根目录 TypeScript 与 LSP 验证约定
+
+- 根目录当前有意不安装 Pi runtime，也没有根级 `tsconfig.json`、`devDependencies` 或 `@types/node`；`@earendil-works/pi-*` 只作为 optional host peer dependencies。TypeScript LSP 因而会把根目录 `.ts` 文件放入 inferred project，不能把宿主 Pi 的运行时解析能力等同于仓库内静态类型环境。
+- 每个任务首次对相关根目录 TypeScript 文件调用 `lsp_diagnostics` 时先建立并记录基线；后续只关注相对基线新增、消失或位置变化的诊断。文件和类型环境都未变化时不得重复调用 LSP 并重复报告同一组结果。
+- 当前可预期的基线包括：宿主 peer 缺失导致的 `TS2307`（例如找不到 `@earendil-works/pi-coding-agent`），Node 类型缺失导致的 `node:*` / `node:test` / `node:assert` `TS2591`，以及由这些上游类型缺失级联产生的 `TS7006`、`TS18048`、`TS2722` 等。遇到级联错误时先确认其是否随缺失类型而产生，不要把它们直接归因于本次实现。
+- 已知基线不等于忽略所有诊断：凡是无法由上述缺失依赖解释的新语法错误、结构类型错误、错误属性访问或本次修改所在代码的新诊断，必须修复并重新验证。交付时应把“已知类型环境基线”和“本次新增诊断”分开说明。
+- 不得为了消除 LSP 基线而在根包安装第二套 Pi runtime、加入机器相关的宿主绝对路径或提交只在单机有效的 `paths` 映射。若确需新增根级 `tsconfig.json`、`@types/node` 或其他开发类型环境，必须作为明确的仓库设计变更评估，并同步更新依赖、锁文件和本文档。
+- 不要从泛型或重载的 `ExtensionAPI` 方法直接用 `Parameters<...>` 猜取具体工具定义；解析失败时它可能退化为 `unknown`。包装第三方工具时优先使用上游导出的具体类型；没有稳定导出时定义覆盖实际访问字段的最小结构类型，并用运行时集成测试验证。
+- `node --test` 可直接测试仓库内的纯 TypeScript helper，但测试入口不得静态导入 `node_modules` 中的 `.ts`；Node 原生 type stripping 会对这种路径报 `ERR_UNSUPPORTED_NODE_MODULES_TYPE_STRIPPING`。第三方 TypeScript 扩展 wrapper 应拆出本地纯 helper 做单元测试，并通过隔离的临时 Pi agent/jiti 加载验证真实扩展入口。
+- 对根目录扩展的最终验证优先组合使用：纯 helper 的 `node --test`、`git diff --check`、所需 npm 锁文件检查，以及隔离 Pi 环境的扩展加载。LSP 启动成功、单元测试通过和真实 Pi 加载通过是不同证据，不得互相替代或把类型环境基线误报为 LSP 后端启动失败。

-# Hippo Memory - Pi Extension
-
-> **my-pi packaging note:** this official source is bundled and loaded directly by the root package; do not copy it to another Pi extension directory. Use the root `install.sh`, `update.sh`, and `uninstall.sh` prompts to manage the matching global CLI. Upstream's original manual instructions are retained below for reference.
-
-Biologically-inspired memory for [Pi coding agent](https://github.com/badlogic/pi-mono). Memories decay by default, retrieval strengthens them, errors stick longer, and sleep consolidation compresses episodes into patterns.
-
-## Install
-
-```bash
-# Install hippo CLI
-npm install -g hippo-memory
-
-# Init hippo in your project (or scan all repos)
-hippo init
-# or: hippo init --scan ~
-
-# Copy extension to Pi's extensions directory
-cp -r extensions/pi-extension ~/.pi/agent/extensions/hippo-memory
-```
-
-Or for project-level:
-```bash
-cp -r extensions/pi-extension .pi/extensions/hippo-memory
-```
-
-## What it does
-
-| Automatic | When |
-|---|---|
-| Injects memory context | Session start |
-| Captures tool errors | After any failed tool call |
-| Learns from git | On `hippo sleep` (session end) |
-| Consolidates memories | On `hippo sleep` (session end) |
-| Shares to global store | On `hippo sleep` (session end) |
-
-Error capture has three filters to prevent memory pollution:
-1. Noise pattern filter (timeouts, ECONNREFUSED, etc.)
-2. Per-session rate limit (max 5 error memories)
-3. Per-session deduplication
-
-## Tools
-
-The extension registers 5 tools for the LLM:
-
-| Tool | Description |
-|---|---|
-| `hippo_recall` | Search memories by topic |
-| `hippo_remember` | Store a new memory |
-| `hippo_outcome` | Report if memories were helpful |
-| `hippo_status` | Check memory health |
-| `hippo_context` | Smart context from git state |
-
-## Config
-
-Edit the `DEFAULT_CONFIG` object at the top of `index.ts`:
-
-```typescript
-const DEFAULT_CONFIG = {
-  budget: 4000,           // Token budget for recall
-  contextBudget: 1500,    // Token budget for auto-context
-  framing: 'observe',     // observe | suggest | assert
-  autoContext: true,       // Inject context at session start
-  autoLearn: true,         // Capture tool errors
-  autoSleep: true,         // Run consolidation on exit
-  maxErrorsPerSession: 5,  // Error capture rate limit
-};
-```
-
-## Requirements
-
-- `hippo-memory` CLI installed globally: `npm install -g hippo-memory`
-- `.hippo/` initialized in your project: `hippo init`
-- Pi coding agent
-
-## How it differs from the OpenClaw plugin
-
-Same core behavior. The Pi extension uses Pi's event system (`session_start`, `tool_result`, `session_shutdown`) instead of OpenClaw's hook system. Both use `execFileSync` with args arrays (no shell injection).

+# Changelog
+
+All notable user-facing changes to `pi-chrome`.
+
+## Unreleased — my-pi maintained build
+
+- **Context Mode snapshot handoff.** `chrome_snapshot`, `chrome_find`, and action results with `includeSnapshot=true` atomically save the full structured snapshot to a private workspace-local `.pi/chrome-context/<session>/<target>/snapshot.json` file and return only bounded metadata plus a path for `ctx_execute_file`. Each target keeps only its latest capture; interactions invalidate stale captures, and session shutdown/revoke/authorization expiry removes them.
+- **Compact find results.** `chrome_find` keeps its top 20 ranked uid/coordinate matches inline while the full page structure stays in the session-local capture.
+- **Complete authorization deactivation.** `chrome_find` and `chrome_inspect` are now included in the authoritative Chrome tool-name set so revoke/expiry deactivates all 21 registered tools.
+
+## 0.15.40 — 2026-06-22
+
+- **Automation targets reuse the session tab group.** When `chrome_navigate` / implicit page actions create a new pi-chrome automation tab, it is now created in this session's existing tab-group window when possible and joins that same group, avoiding duplicate same-title `Pi Session: ...` groups.
+
+## 0.15.39 — 2026-06-07
+
+- **Dedicated automation tab/window (no more hijacking your active tab).** When a chrome_* action runs without an explicit target, pi-chrome now opens and reuses a dedicated automation window it owns (falling back to a dedicated tab if a separate window can't be created) instead of navigating whatever tab you currently have open. Your existing tabs/windows are left untouched. Pass `targetId`/`urlIncludes`/`titleIncludes` to act on a specific existing tab.
+  - **Per session.** Ownership is scoped to the calling Pi session, so concurrent sessions sharing one companion extension each get their own automation window instead of fighting over a tab.
+  - **Survives `/reload` and Chrome service-worker restarts.** Ownership is tracked by id and mirrored to `chrome.storage.session`, so the window is reused rather than orphaned.
+  - **Guarded tab management.** `chrome_tab` `activate`/`close`/`group`/`ungroup` with no target now act on the session's automation tab if present, otherwise error — they no longer fall back to (or spawn a throwaway tab to touch) your active tab.
+  - **Safe, non-blocking cleanup.** The owned target is closed on `/chrome revoke` and on real session end (never on `/reload`); cleanup only ever closes the calling session's own window/tab — never user tabs/windows or another session's target — and is fire-and-forget so it never blocks `/quit`, `/reload`, or session end.
+- **One session, one tab group.** `chrome_tab new` now reuses this session's existing Pi tab group even when another Chrome window is focused, creating the tab in that group's window because Chrome tab groups cannot span windows. The old `group:false` / `groupTitle:""` opt-out is ignored; Pi-created tabs are never intentionally left ungrouped, and a grouping failure closes the just-created tab before returning an error.
+
+## 0.15.38 — 2026-06-07
+
+- **Overlay-safe click/fill fallbacks.** `chrome_click` and `chrome_fill` now fall back to DOM-dispatched click/value events when Chrome's debugger input path is blocked by another extension overlay (for example password-manager/autofill UI), unless `domFallback:false` is passed.
+
+## 0.15.37 — 2026-06-07
+
+- **Hardened Chrome input targeting.** `chrome_click`/`chrome_fill`/related input paths now fail fast with resolved tab/CDP target metadata when debugger attach hits a stale or protected target, instead of surfacing bare `chrome-extension://` errors or hanging until the bridge timeout.
+- **Internal timeouts and cleanup.** Companion extension commands, debugger attach, CDP commands, and script injection now have shorter internal timeouts with debugger cleanup, so stuck input dispatch returns actionable errors before the 30s bridge timeout.
+- **Clear stale uid errors.** Snapshot uids that no longer map to live elements now report `snapshot uid ... is stale; refresh chrome_snapshot`.
+- **`chrome_fill` fallback.** If real CDP input is blocked by another extension overlay (for example password-manager/autofill UI), `chrome_fill` falls back to setting the field value through the page DOM and dispatching `input`/`change` events, unless `domFallback:false` is passed.
+
+## 0.15.36 — 2026-06-03
+
+- **Richer page observation.** `chrome_snapshot` now returns a concise, agent-friendly observation — structural layout/context, page hints, visible actions, form fields, a page map, query matches, and a diff of changes since the previous snapshot — instead of a raw JSON dump. New `mode` (`auto`/`interactive`/`forms`/`pageMap`/`text`/`changes`/`full`), `query`, and `maxTextChars` parameters let the agent zoom in instead of dumping the whole page.
+- **New `chrome_find` tool.** Find elements, regions, or text by natural-language query (`'merge button'`, `'email error'`) and get ranked matches with stable uids and coordinates. Thin wrapper around `chrome_snapshot({ query })`.
+- **New `chrome_inspect` tool.** Inspect one snapshot uid/selector deeply: nearby text, nearby actions, form context, ancestors, and a suggested click target. Falls back to a focused snapshot if the loaded extension predates `page.inspect`.
+- **`includeSnapshot` now embeds the formatted snapshot.** `chrome_click`/`chrome_type`/`chrome_fill`/`chrome_key` with `includeSnapshot=true` append the fresh concise snapshot to the tool text so the agent can verify in one round trip.
+- **Snapshot logic moved to a packaged `snapshot_injected.js`.** The MAIN-world snapshot/inspect implementation ships as an eval-free packaged script, shared `window.__PI_CHROME_STATE__` (same `el-` uid scheme) with the existing input helpers.
+
+## 0.15.34 — 2026-06-01
+
+- **Every tab Pi uses now joins the session group.** Previously only `chrome_tab new`/`group` created/used the `Pi Session: <name-or-id>` group; tabs Pi drove via `page.*` actions (navigate, click, type, snapshot, screenshot, etc.) on the existing/active tab stayed ungrouped. Now any ungrouped tab Pi interacts with is pulled into this session's group, so the user can see exactly which tabs Pi is driving. Tabs already in a group (the user's or another session's) are left untouched.
+- **Fixed punctuation being dropped by `chrome_type`/`chrome_key`.** Printable punctuation derived its `code`/virtual-keyCode from `charCodeAt()`, so `.` mapped to keyCode 46 (VK_DELETE), `-` to 45 (VK_INSERT), shifted symbols to wrong codes, and `code` was the raw char (`"."`) instead of the physical key (`"Period"`). Apps with keydown handlers (e.g. Gmail's filter address field) saw a Delete/Insert key and silently rejected the character. Both the CDP and DOM-event input paths now resolve keys through a proper US-keyboard layout map.
+
+## 0.15.33 — 2026-05-31
+
+- **Background is now the default.** `chrome_*` tools run silently without focusing Chrome unless you opt in. Pass `background: false` per call, or run `/chrome background off`, to bring Chrome forward and watch. Tool/param descriptions and docs updated to match.
+
+## 0.15.32 — 2026-05-31
+
+- **Session tab-group naming tweak.** Per-session groups are now titled `Pi Session: <name-or-id>` (added a colon separator).
+
+## 0.15.31 — 2026-05-31
+
+Per-session tab groups.
+
+- **Each Pi session gets its own tab group.** Auto-grouped tabs are now named `Pi Session <name>` using the session's display name, falling back to the session id when unnamed. Multiple Pi sessions driving the same Chrome no longer share one group — each collects its tabs separately. Pass an explicit `groupTitle` to override, or `group:false` / `groupTitle:""` on `action=new` to opt out.
+
+## 0.15.30 — 2026-05-31
+
+Tab grouping for `chrome_tab`.
+
+- **Pi-opened tabs auto-group.** `action=new` now drops every tab into a shared `Pi` tab group per window by default (created once, then reused), so agent tabs stay visually separated from your own. Opt out per call with `groupTitle:""` or `group:false`.
+- **`chrome_tab` can group/ungroup tabs.** New `action=group` (and `action=ungroup`) plus `groupTitle`/`groupColor` params. Grouping reuses an existing same-title group in the window instead of spawning duplicates. Defaults: title `Pi`, color `blue`; color validated against Chrome's 9 group colors. Target an existing tab with `targetId`/`urlIncludes`/`titleIncludes`.
+- **Tab listings include group info.** `formatTab` now reports `groupId` and a `group` record (`title`, `color`, `collapsed`, `windowId`, `piGroup`), and `chrome_tab list` prefixes grouped tabs with `[Group Title]`.
+- Requires the new `tabGroups` extension permission — reload the companion extension after updating.
+
+## 0.15.29 — 2026-05-31
+
+Strict-CSP support: `chrome_evaluate`, `chrome_snapshot`, `chrome_wait_for`, and `chrome_navigate initScript` now work on pages that block `unsafe-eval`.
+
+- **CDP-based evaluation bypasses page CSP.** `chrome_evaluate`/`chrome_snapshot` (and all snapshot-driven inspection) previously ran user code in the page MAIN world via the **Function constructor**, which is blocked by `script-src 'self'` without `'unsafe-eval'` — so they returned null/empty (or `EvalError`) on github.com and many bank/SaaS apps. They now evaluate through CDP `Runtime.evaluate`, a DevTools protocol command that is not subject to the page's Content-Security-Policy. Rich return values (undefined/function/symbol/bigint/Error markers, DOMRect expansion) and the expression/statement fallback are preserved.
+- **`chrome_wait_for` polls via CDP.** The selector/expression polling loop moved from in-page `new Function()` to service-worker-side CDP evaluation, so waits work under strict CSP too.
+- **`chrome_navigate initScript` injects via CDP.** Document-start init scripts now register with `Page.addScriptToEvaluateOnNewDocument` instead of `new Function()` on `webNavigation.onCommitted`, so seeding localStorage / stubbing `Date.now` works under strict CSP.
+- **Tests.** Added a Node unit harness (`test-suite/unit/csp-eval.test.mjs`, run via `npm test`) validating the evaluate/execute/waitFor refactor, and an in-browser regression challenge (42 `strict-csp-evaluate`) that reads a JS-only secret under strict CSP. Updated challenge 39's notes and docs (FAQ, EXAMPLES, COMPARISON, primer) which previously stated eval/snapshot fail under strict CSP.
+
+## 0.15.28 — 2026-05-31
+
+Low-risk reliability fixes from a long-session bug report.
+
+- **Bridge self-heals when the owning session dies.** A Pi session running in shared-client mode used to fail every `chrome_*` call with a bare `fetch failed` once the session that owned `127.0.0.1:17318` exited. The client now detects the unreachable owner, takes over the bridge port, and re-runs the command locally instead of staying stuck.
+- **Actionable timeout messages.** A 30s timeout now says *why*: extension not polling (not installed/closed), polling but didn't pick up the command, or picked it up but never returned a result (long-running action / failed result post) — instead of one generic message.
+- **`chrome_type` / `chrome_fill` DOM path no longer throws `pressKeyInPage is not defined`.** The helper is now included in the injected MAIN-world helper set and its callers await it.
+- **`getBoundingClientRect()` / DOMRect now serialize in `chrome_evaluate`.** DOMRect-like values return `{x,y,width,height,top,right,bottom,left}` instead of `{}`.
+- **Clearer stale-target errors.** A missing `targetId` now lists the current tabs and suggests re-targeting via `chrome_tab list` or `urlIncludes`/`titleIncludes`, instead of a bare "No matching Chrome tab found".
+- **`pageMutated=false` no longer reads as failure.** Click/type/fill summaries explain it's a coarse heuristic that can miss real effects, and suggest verifying with `includeSnapshot`.
+
+## 0.15.26 — 2026-05-16
+
+- **Documentation accuracy.** README, FAQ, examples, comparison, and test-suite docs now describe the 41-challenge suite, gate buckets, strict-CSP fallback, and current human-vs-extension limitations.
+- **Published benchmark assets.** The npm package now includes `test-suite/` so the documented benchmark pages are available from installed packages, not only from the repository checkout.
+
+## 0.15.25 — 2026-05-16
+
+- **Reload after older installs.** `/reload` now recovers from stale singleton state left by pi-chrome 0.15.19 and earlier instead of skipping the freshly loaded extension.
+- **Test suite coverage.** Added gate buckets plus strict-CSP fallback, dynamic wait readiness, and explicit tab lifecycle challenges.
+
+## 0.15.24 — 2026-05-16
+
+- **Unload Chrome tools on lock.** `chrome_*` tools now deactivate when `/chrome revoke` runs or timed authorization expires, keeping the prompt/tool list small after Chrome control locks again.
+
+## 0.15.23 — 2026-05-16
+
+- **Attribution.** The 0.15.22 features below are pulled from Dani Bednarski's fork (`DaniBedz/pi-chrome`). Thank you, Dani.
+
+## 0.15.22 — 2026-05-16
+
+Features in this release are pulled from Dani Bednarski's fork (`DaniBedz/pi-chrome`). Thank you, Dani.
+
+- **Earlier page-load capture.** Companion extension now injects console/network instrumentation at `document_start`, so initial React render errors and early API calls show up in `chrome_list_console_messages` / `chrome_list_network_requests`.
+- **Quieter locked state.** Startup no longer shows a persistent Chrome bridge notification/status item before authorization; status bar appears only when Chrome control is authorized.
+- **Lazy tool registration.** `chrome_*` tools and primer are registered only after `/chrome authorize`, reducing prompt/tool overhead while Chrome control is locked.
+
+## 0.15.21 — 2026-05-16
+
+### Reverted 0.16.x and 0.17.x lines
+
+- Versions 0.16.0 through 0.17.2 were published to npm and subsequently unpublished. 0.17.3 was prepared locally but never published. The work introduced in those versions — mandatory pairing, signed-envelope auth, standalone bridge daemon, idempotent onboard, etc. — is reachable only via git tags (`v0.16.0` … `v0.17.3`) and is not in the current main branch.
+- This release is **tree-equivalent to 0.15.20** with a version-only bump so future patch releases can ship cleanly.
+
+## 0.15.20 — 2026-05-15
+
+- **Interruptible `chrome_*` tools.** All `chrome_*` tools now honor the agent harness `AbortSignal`, so pressing Esc aborts in-flight bridge calls (including the long-polling `chrome_wait_for`) immediately instead of waiting out the full `timeoutMs`.
+
+## 0.15.19 — 2026-05-14
+
+- **Simpler package description.** README hero and npm/pi.dev description now use the same concise authorization-focused sentence.
+
+## 0.15.18 — 2026-05-14
+
+- **Cleaner package description.** npm/pi.dev description now focuses on the existing Chrome profile and explicit authorization model, avoiding implementation details.
+
+## 0.15.17 — 2026-05-14
+
+- **Docs accuracy pass.** Updated README, FAQ, comparison, contributing notes, and package metadata for the current real-input-only, terminal-authorized tool surface.
+- **Input verification fix.** `includeSnapshot=true` now works for `chrome_click`, `chrome_type`, `chrome_fill`, and `chrome_key`, returning the Chrome-input result plus a fresh snapshot.
+
+## 0.15.16 — 2026-05-14
+
+- **Visible `/chrome` loading state.** Bare `/chrome` and `/chrome status` now immediately say “Checking Chrome connection…” before probing the companion extension, so a slow Chrome bridge no longer looks like the command did nothing.
+
+## 0.15.15 — 2026-05-14
+
+- **Terminal authorization restored.** `/chrome authorize` is back to terminal-based confirmation. Removed the browser-side Chrome consent page and companion-extension consent polling.
+
+## 0.15.14 — 2026-05-14
+
+- **Clearer consent wait state.** After the Chrome approval page opens, Pi now says “Approve or deny the Chrome approval page to continue” instead of looking stuck at the launch step.
+
+## 0.15.13 — 2026-05-14
+
+- **Fix Chrome-side consent hang.** `/chrome authorize` now launches the browser consent page as a short command, then polls for the decision. This avoids holding one long extension command open while the user reads/clicks the page, which could leave Pi stuck at “Opening Chrome approval page…”.
+
+## 0.15.12 — 2026-05-14
+
+- **Docs accuracy.** Clarified that the bundled Chrome extension currently polls `127.0.0.1:17318`; custom bridge ports are not supported without editing/reloading the extension source. Also softened the unpacked-extension rationale to avoid overstating Web Store limitations and fixed stale strict-CSP guidance for `chrome_evaluate`.
+
+## 0.15.11 — 2026-05-14
+
+- **README cleanup.** Removed the Playwright/CDP/Selenium comparison table and low-signal Composes with / Contributing sections from the package page because they are noisy and easy to drift.
+
+## 0.15.10 — 2026-05-14
+
+- **Browser-side Chrome consent.** `/chrome authorize` now opens a Pi Chrome Connector approval page inside Chrome showing duration, workspace, process id, and extension/package versions. Chrome control unlocks only after the user approves there; denying, closing the tab, or timeout leaves control locked.
+- **README cleanup.** Removed npm/download/license shield badges from the package page because they are noisy and easy to drift.

+## 0.15.9 — 2026-05-14
+
+- **Tighter `/chrome` menu.** Removed the redundant “Connection status” item from the interactive `/chrome` menu because connection/auth/background are already shown in the menu header. `/chrome status` remains available as a slash command.
+
+## 0.15.8 — 2026-05-14
+
+- **Simpler `/chrome` submenus.** Authorize menu now offers 15 minutes, 30 minutes, indefinite, and custom minutes only. Background menu now offers only foreground/background. Esc from a submenu returns to the main `/chrome` menu.
+
+## 0.15.7 — 2026-05-14
+
+- **Grouped `/chrome` menu.** Bare `/chrome` now opens a status dashboard with grouped actions: authorize, lock, status, doctor, background/watch mode, and onboard. Authorize/background open submenus instead of showing one flat command list.
+
+## 0.15.6 — 2026-05-14
+
+- **Bare `/chrome` is now a command menu.** Running `/chrome` shows interactive options for every `/chrome ...` command, including authorize/revoke/status/doctor/onboard/background variants.
+
+## 0.15.5 — 2026-05-14
+
+- **Chrome control authorization.** `chrome_*` tools are locked until the user runs `/chrome authorize` in the current Pi session. Grants can be one command, 15 minutes, 1 hour, or the session; `/chrome revoke` locks control again and `/chrome status` shows auth state.
+- **Browser-origin bridge hardening.** The loopback bridge no longer sends wildcard CORS headers. `/command` accepts only local-process requests, while extension polling/result endpoints reject non-extension browser origins, blocking ordinary web pages from driving or draining the bridge through `127.0.0.1`.
+
+## 0.15.4 — 2026-05-14
+
+- **Quiet renamed to background.** Public UX now uses `/chrome background [on|off|toggle|status]` and docs/status say “run in background” instead of “quiet mode”.
+
+## 0.15.3 — 2026-05-14
+
+- **Chrome real input only.** Public trusted/synthetic mode controls were removed. Interactive tools now always use Chrome's real input layer; `/chrome clicks` and public `trusted` parameters are gone.
+
+## 0.15.2 — 2026-05-13
+
+- **Recipe prompts rewritten in user-language.** Earlier recipes leaked tool names into the `You:` prompts ("Use `chrome_tab list` to find my GitHub notifications tab…"), implying users need to know the tool catalog before they can ask anything. Prompts now read as natural intent; the agent trace below each one still shows the `chrome_*` primitives the agent picked. Affects the 30-second try-this block, all 3 hero recipes (PR triage / Linear standup / Bug repro), and 3 of the 6 collapsed recipes (auth-only data pull, network forensics, file upload).
+
+## 0.15.1 — 2026-05-13
+
+- **Architecture diagram now renders on pi.dev.** Replaced Unicode box-drawing characters (`┌─┐│└┘┬▼`) with plain ASCII (`+ - | v`). Pi.dev's monospace font was dropping the horizontal `─` glyphs, leaving the diagram as floating vertical bars. ASCII renders everywhere.
+- **`author` switched to object form.** Was `"tianrendong (Earendil Inc.)"` — npm's author-string spec parses `(parens)` as the URL slot, so `"Earendil Inc."` ended up in `author.url`. Now `{ "name": "tianrendong", "company": "Earendil Inc." }`.
+
+## 0.15.0 — 2026-05-13
+
+- **README rewrite — top-3 recipes as terminal mockups.** PR triage, Linear standup, and Bug-repro-with-evidence each get a copy-pasteable prompt → tool trace → result block modeled on the hero example. The other six recipes (form auto-fill, admin cross-check, visual diff, auth-only data pull, network forensics, file upload) collapsed into a `<details>` block so the section sells before it catalogs.
+- **Comparison table rewritten.** Dropped the all-✅ "Works on strict-CSP pages" row (zero signal). New table leads with "Time from `pi install` → first useful action on your real account" (~60s vs. hours) and "Survives MFA / SSO without code" (✅ already logged in). Multi-session row reframed as the bolded "Multiple agents drive the same Chrome at once". Footnote ² rewritten to highlight mode-aware scoring + open invitation for competing tools to PR their scores.
+- **Section reorder: sells before catalogs.** New flow: hero → 60-second install → 30-second try-this → killer recipes → comparison → honest results → tool catalog → click/watch modes (with Diagnostics folded in) → architecture → benchmark suite → security model & why unpacked (combined) → composes-with → roadmap → contributing → license. Hero blockquote now precedes shields badges so pi.dev no longer scrapes a broken-image badge as the description. Package `description` shortened to 255 chars so pi.dev hero stops truncating mid-word. `author` set to `"tianrendong (Earendil Inc.)"`.
+
+## 0.14.9
+
+- Primer (agent system prompt) now teaches the **trusted-mode escape hatch** explicitly. Previously the bridge would hit a CSP-locked page (github.com, banks, many SaaS apps), `chrome_evaluate`/`chrome_snapshot` would throw `EvalError: 'unsafe-eval' is not an allowed source of script`, and the agent would conclude *"bridge can't drive this page"* and ask the user for a fallback. New primer makes three things self-discoverable: (1) `trusted: true` on click/type/key/fill/hover/drag/scroll dispatches through chrome.debugger / CDP and bypasses page CSP entirely, (2) the recipe for strict-CSP pages is `chrome_screenshot` + trusted input at viewport coordinates, (3) when synthetic input produces no `pageMutated` or you see a CSP/eval error, **escalate to `trusted: true` yourself instead of asking the user**. Also corrects the old claim that `chrome_evaluate` works without `'unsafe-eval'` (it does not — Function constructor is gated by `script-src`).
+- Add `scripts/sync-manifest-version.js` wired to npm's `version` + `prepublishOnly` lifecycle hooks. Bumping the package version with `npm version <bump>` now auto-syncs `extensions/chrome-profile-bridge/browser-extension/manifest.json` and stages it into the version commit — kills the recurring drift class (cf. 0.14.4, 0.14.8, this fix).
+
+## 0.14.8
+
+- Repo moved to its own home: https://github.com/tianrendong/pi-chrome. No code changes; updated `repository`, `homepage`, and `bugs` URLs in `package.json`.
+
+## 0.14.7
+
+- Replace "30+ challenges" hand-wave in README + COMPARISON.md with the accurate framing from chrome-benchmark: **38 primitive challenges + 4 hermetic BrowserGym-style long-horizon tasks**, scored by **expected-outcome-by-mode** (not raw PASS count). Explains why a synthetic-events tool isn't supposed to satisfy a clipboard user-activation gate — matching that expectation is the pass.
+
+## 0.14.6
+
+- Fix Browser Use license in `docs/COMPARISON.md`: MIT (not Apache-2.0). Confirmed against upstream LICENSE on GitHub.
+
+## 0.14.5
+
+- `docs/COMPARISON.md` rewritten with a three-axis landscape (drivers / agent frameworks / cloud providers). Adds Browser Use, Stagehand, Skyvern, Magnitude, Alumnium, OpenAI Operator, Project Mariner, Surfer 2, Anthropic Computer Use, Browserbase, Steel.dev, Hyperbrowser, Anchor, Browserless. Adds Interop section, public-benchmark cheat sheet (WebArena, WorkArena++, BrowseComp, Mind2Web 2, WebChoreArena, MiniWoB++, BrowserGym).
+- README gains a one-liner pointing at the new three-axis framing.
+- Sourced from `benchmark-search` session research. No code changes.
+
+## 0.14.4
+
+- Sync `manifest.json` version to match `package.json` (0.14.3 shipped with stale manifest, would trigger spurious `/chrome doctor` drift warnings). No code or behavior changes.
+
+## 0.14.3
+
+- Documentation & discoverability overhaul.
+- New README: hero, alternatives comparison table, 20-tool reference grouped by job, killer recipes, architecture diagram, honest-results explainer, benchmark suite plug.
+- `docs/COMPARISON.md` — deep comparison vs Playwright / Puppeteer / Stagehand / browser-use / Selenium.
+- `docs/EXAMPLES.md` — ready-to-paste agent prompts (PR triage, Linear standup, bug repro, network forensics, multi-tab admin cross-check, etc.).
+- `docs/FAQ.md` — covers Brave/Arc, incognito, detection, banner, multi-session, CSP, file uploads, common envelope causes.
+- `CHANGELOG.md`, `CONTRIBUTING.md`, `SECURITY.md`, `LICENSE` added.
+- `package.json`: `homepage`, `repository`, `bugs`, expanded keywords for npm search.
+- No code changes to the tools or extension.
+
+## 0.14.2
+
+- Recover from foreign-extension input overlays so input tools don't get hijacked by other Chrome extensions.
+
+## 0.14.1
+
+- Harder `attachDebugger` retry path so trusted clicks survive transient Chrome debugger contention.
+- New `trusted.debug` diagnostic surface.
+
+## 0.14.0
+
+- Bare `/chrome` opens a `SettingsList` dialog. `space` cycles values, `enter` saves.
+
+## 0.13.0
+
+- Flattened `/chrome` tree. Cycle-on-pick for `clicks` / `quiet`. Status header at the top of the picker.
+
+## 0.12.1
+
+- Fixed anti-automation regressions across 7 benchmark challenges (`07/13/21/27/28`).
+
+## 0.12.0
+
+- Unified all slash commands under `/chrome` (`/chrome doctor`, `/chrome onboard`, `/chrome clicks`, `/chrome quiet`).
+
+## 0.11.x
+
+- Plain-English audit pass across `/chrome doctor`, `/chrome onboard`, `/chrome quiet`, README.
+- `chrome_tap` (real CDP touch events).
+- Smoother `trustedScroll`; CDP debugger auto-recovers from detach.
+- Smart-auto trusted mode default. Extension renamed to **Pi Chrome Connector**.
+- Per-event scroll delta cap so IntersectionObserver thresholds land naturally.
+
+## 0.10.x
+
+- Trusted-input mode via `chrome.debugger` (CDP) — opt-in, indistinguishable-from-human clicks/keys.
+- `chrome_key` modifiers (Cmd+V, Ctrl+Shift+Tab, etc.) for trusted chords.
+- Interactive `/chrome-trusted` picker (later folded into `/chrome`).
+
+## 0.9.x
+
+- Humanized synthetic input (pointer paths, key cadence variance).
+- Anti-automation benchmark test suite landed in `test-suite/`.
+
+## 0.8.0
+
+- `chrome_evaluate` no longer returns `null` for valid expressions — dedicated MAIN-world `evaluateInTab` pipeline with statement-mode fallback and tagged envelope for `undefined`/errors/symbols/bigints.
+- Truthful action result envelopes: `isTrusted`, `defaultPrevented`, `elementVisible`, `occludedBy`, `valueMatches`, `pageMutated`.
+- Extended `/chrome doctor`: bridge mode/URL, extension version drift, MAIN-world helper injection, `navigator.webdriver` fingerprint, CDP availability probe.
+- Removed misleading `returnByValue` param. Implemented `chrome_screenshot.fullPage` via tile stitching.
+- Autoplay-gate heuristic for `chrome_click`.
+
+## 0.7.0
+
+- Initial public `pi-chrome` release. Companion Chrome extension + local bridge + first tool set.

+# Contributing to pi-chrome
+
+Thanks for considering a contribution. pi-chrome aims to be the **de-facto browser-control toolkit for Pi agents** — that means a few non-negotiables.
+
+## Non-negotiables
+
+1. **No re-login.** Every change must keep working against the user's already-signed-in Chrome profile. Anything that requires a fresh profile or extra auth steps is out of scope.
+2. **Verifiable action results.** Input tools must return structured details and support `includeSnapshot` where verification matters. Agents need enough evidence to avoid blind retries.
+3. **Chrome real input.** Interactive controls use Chrome's input layer through `chrome.debugger`; do not re-expose synthetic/untrusted input as public UX.
+4. **Benchmarks gate features.** Add a page in `test-suite/` that fails before your change and passes after. We accept PRs faster when there's a green/red verdict to point at.
+
+## Local dev
+
+```bash
+# Link from a checkout
+pi install ./pi-chrome
+
+# Run the benchmark dashboard
+cd test-suite
+python3 -m http.server 8765
+# open http://127.0.0.1:8765/ in the Chrome window pi-chrome controls
+```
+
+## Adding a new tool
+
+1. Register in `extensions/chrome-profile-bridge/index.ts` (the `register*Tool` calls near line 840+).
+2. Implement the handler in `extensions/chrome-profile-bridge/browser-extension/service_worker.js`.
+3. Return structured details and support `includeSnapshot` for user-visible state changes when relevant.
+4. Add a benchmark page under `test-suite/challenges/` and a manifest entry.
+5. Update `README.md` "What an agent gets" table.
+6. Add a `CHANGELOG.md` entry.
+
+## Filing a bug
+
+Include:
+
+- `/chrome doctor` output
+- `pi-chrome` version + extension version (the `doctor` output prints both)
+- The exact tool call + the result envelope you got
+- Page URL or a minimal repro page in `test-suite/`
+
+## Releasing
+
+- Bump `package.json` version.
+- Move `CHANGELOG.md` notes from the working section to the new version header.
+- `npm publish --access public`.
+
+## Code of conduct
+
+Be kind, be precise, ship things. PRs that break the "no re-login" promise will be closed with a note explaining which non-negotiable they hit.

+# pi-chrome
+
+> Let [Pi](https://pi.dev) use your existing signed-in Chrome profile after explicit authorization.
+
+**MIT · 0 runtime deps · loopback-only bridge (`127.0.0.1:17318`) · inspectable unpacked Chrome extension.** Review [`extensions/chrome-profile-bridge/browser-extension/`](./extensions/chrome-profile-bridge/browser-extension) before loading. Verify setup with `/chrome doctor`.
+
+```text
+You:    "Find my open GitHub PR tab, summarize review state, and screenshot failing CI."
+Agent:  chrome_tab(list) → chrome_snapshot(...) → overflow_query(jsonPath) → chrome_screenshot(...)
+        ✓ 3 reviewers, 1 change requested, CI red on iOS. Saved → .pi/chrome-screenshots/ci.png
+You:    [keeps coding — agent never asked you to log in]
+```
+
+`pi-chrome` runs through a small Chrome extension inside the Chrome profile **you already use** — including sites where you're already signed in. Agents can inspect or control Chrome only after you run `/chrome authorize` in current Pi session.
+
+---
+
+## Install
+
+```bash
+pi install npm:pi-chrome
+```
+
+In Pi:
+
+```text
+/chrome onboard
+```
+
+This opens `chrome://extensions` and copies bundled extension path. In Chrome Extensions:
+
+1. Turn on **Developer mode**.
+2. Click **Load unpacked**.
+3. Open path field with **Cmd+Shift+G** on macOS or **Ctrl+L** on Windows/Linux.
+4. Paste copied path.
+5. Press Enter.
+
+Reload Pi so installed package loads:
+
+```text
+/reload
+```
+
+Check bridge:
+
+```text
+/chrome doctor
+```
+
+You should see:
+
+```text
+✓ Chrome is connected (...)
+```
+
+Authorize current session:
+
+```text
+/chrome authorize
+/chrome doctor
+```
+
+Second doctor run should show all checks passing.
+
+---
+
+## What it can do
+
+- Read and summarize pages you're already signed into.
+- Click, type, fill forms, scroll, drag, tap, and upload files.
+- Capture screenshots for bugs, PRs, and demos.
+- Inspect console logs and captured `fetch`/`XMLHttpRequest` responses.
+- Manage tabs without taking over your active window.
+
+Tool parameters and gotchas are documented inline in Pi.
+
+### Snapshots and pi-overflow
+
+In this maintained build, `chrome_snapshot` and actions with `includeSnapshot=true` return the full structured page snapshot as JSON directly in the tool result. `chrome_find` returns only up to 20 compact ranked matches.
+
+Large snapshots are bounded by the bundle's `pi-overflow` extension: the result keeps a bounded view and the full original is stored, marked with `[pi-overflow id=…]`. Extract the uids, text, or state you need with `overflow_query` — a `jsonPath` such as `elements[0].uid` or `summary.focused`, or a regex `search` — instead of taking another snapshot. Any page interaction makes earlier snapshots stale, so take a fresh one (or pass `includeSnapshot=true` on the action) when the page has changed.
+
+---
+
+## Safety model
+
+Chrome control is locked by default. Authorize per Pi session:
+
+```text
+/chrome authorize          # 15 minutes
+/chrome authorize 30m      # custom duration
+/chrome authorize indefinite
+/chrome revoke             # lock again
+/chrome status
+```
+
+Safety properties:
+
+- Extension runs in your real Chrome profile and has broad tab/scripting permissions. Install only from trusted package source.
+- Pi side binds to `127.0.0.1:17318` only; no default network exposure.
+- Bridge rejects browser-origin command requests, so ordinary web pages cannot drive it through CORS.
+- Each Pi session gets its own automation target; user tabs/windows are not closed by cleanup.
+- `/chrome revoke` closes only calling session's automation target.
+
+Security details: [`SECURITY.md`](./SECURITY.md). Architecture details: [`docs/ARCHITECTURE.md`](./docs/ARCHITECTURE.md).
+
+---
+
+## Commands
+
+```text
+/chrome onboard             # guided setup
+/chrome doctor              # connectivity + version + eval checks
+/chrome status              # connection + auth + background state
+/chrome authorize [duration]
+/chrome revoke
+/chrome background on       # default: don't steal focus
+/chrome background off      # foreground/watch mode
+/chrome background status
+```
+
+If loaded extension is older than installed `pi-chrome`, `/chrome doctor` tells you to reload it from `chrome://extensions`.
+
+---
+
+## Limits
+
+`pi-chrome` works best on web-page workflows exposed through DOM, screenshots, tabs, network, console, and Chrome input. It is not full OS automation.
+
+Current limits include native Chrome/OS surfaces, print/save dialogs, permission bubbles, password-manager prompts, cross-origin iframe DOM access, CAPTCHA/bot challenges, passkeys/security keys/biometrics, rich multitouch/pinch/stylus gestures, and arbitrary desktop apps.
+
+For strict-CSP pages, use screenshots + coordinate input when snapshot/evaluate paths are blocked.

+# Security policy
+
+## Reporting a vulnerability
+
+Open a GitHub issue prefixed with `[security]` at https://github.com/tianrendong/pi-chrome/issues, or contact the maintainer directly if the issue is sensitive. Please do **not** include exploit details in a public issue without coordinating first.
+
+## Threat model
+
+`pi-chrome` is a developer tool you install knowingly. It is **not** designed to defend against:
+
+- Hostile pages running in your Chrome trying to detect or escape automation. (Standard browser security boundaries still apply, but a hostile page that already runs in your tab can do anything that page can already do.)
+- Other processes on your local machine. The bridge binds to `127.0.0.1:17318` (loopback only) and chrome_* tools require `/chrome authorize` inside Pi, but the bridge does not authenticate arbitrary non-browser local callers. If your threat model includes hostile local processes running as you, run pi-chrome on a separate user account.
+
+`pi-chrome` **is** designed to:
+
+- Never exfiltrate page state to the network. All communication is loopback (`127.0.0.1`).
+- Surface every action with an honest result envelope so the agent can't silently do the wrong thing.
+- Keep Chrome control locked until the user explicitly runs `/chrome authorize` in the current Pi session.
+- Reject browser-origin command requests to the loopback bridge so ordinary web pages cannot use CORS to drive Chrome.
+
+## The companion extension
+
+The Chrome extension under `extensions/chrome-profile-bridge/browser-extension/` runs with broad permissions: `tabs`, `scripting`, `debugger`, `webNavigation`, etc. **Only install it from a package source you trust.** Read the source before loading. Pin a known-good commit if you're security-sensitive.
+
+## Defaults
+
+- Loopback bridge only. No remote port. No telemetry.
+- Chrome real input layer for interactive controls.
+- Chrome control locked by default; `/chrome authorize` unlocks current Pi session after terminal confirmation, `/chrome revoke` locks it again.
+- Run-in-background optional; tab/window focus is observable by default (the user can see Pi acting).
+
+## Custom ports
+
+The bundled Chrome extension currently polls `127.0.0.1:17318`. Custom bridge ports are not supported without editing the extension source and reloading it.
+
+## Supported versions
+
+The latest minor on npm is supported. Security patches will be released as soon as practical.

+```
+
+## Components
+
+- **Pi extension** — exposes `chrome_*` tools and `/chrome` commands inside Pi.
+- **Loopback bridge** — listens on `127.0.0.1:17318`; no external network bind by default.
+- **Chrome companion extension** — loaded unpacked into your real Chrome profile.
+- **Chrome debugger / CDP** — drives input, screenshots, network/console observation, and evaluation.
+
+## Session model
+
+Multiple Pi sessions can use same Chrome companion extension. First session opens local bridge; later sessions detect it and pipe commands through.
+
+Each Pi session owns its own automation target:
+
+- First chrome action without explicit target opens dedicated automation window.
+- If separate window cannot be created, pi-chrome falls back to dedicated tab.
+- Target survives `/reload` and Chrome service-worker restarts.
+- Ownership is tracked by id and mirrored to `chrome.storage.session`.
+- Cleanup closes only calling session's own target, never user tabs/windows or other sessions' targets.
+
+To point pi-chrome at an existing tab, pass `targetId`, `urlIncludes`, or `titleIncludes`.
+
+## Tab management guards
+
+`chrome_tab` management actions are guarded:
+
+- `activate`, `close`, `group`, and `ungroup` without explicit target act on session automation tab if it exists.
+- If no automation tab exists, operation errors instead of touching your active tab.
+
+## Background mode
+
+By default, chrome calls run in background so Chrome does not steal focus.
+
+```text
+/chrome background on       # background mode
+/chrome background off      # foreground/watch mode
+```
+
+Per-call `background: false` brings Chrome forward for that action. Per-call `background: true` forces background.
+
+## Authorization
+
+Bridge connection alone is not enough. Chrome control stays locked until current Pi session runs:
+
+```text
+/chrome authorize
+```
+
+Authorization expires after configured duration, on `/chrome revoke`, or when Pi exits.
+
+## Unpacked extension choice
+
+`pi-chrome` ships browser extension source as an unpacked folder on purpose:
+
+- easy to inspect before loading
+- no Web Store release delay
+- MIT-licensed source in repo
+- `/chrome doctor` can compare loaded extension version against installed package
+
+Loaded extension has broad tab/scripting permissions inside profile where it is installed. Install only from trusted package source.

+# pi-chrome vs. the rest of the browser-automation landscape
+
+This is the honest "which tool when" page. The browser-automation space has three different layers and people often compare across them — let's not do that.
+
+We benchmark in public — see [`../test-suite/`](../test-suite). Where exact scores matter (WebVoyager, WorkArena++, BrowseComp, Mind2Web 2), check the live leaderboards; they shift monthly.
+
+---
+
+## TL;DR
+
+| You are…                                                       | Use…                            |
+| -------------------------------------------------------------- | ------------------------------- |
+| A Pi agent operator who wants the agent to use **your real Chrome** (logged-in tabs, cookies, extensions) | **pi-chrome**                   |
+| Building a Pi/LLM agent and want low-level browser primitives  | **pi-chrome**                   |
+| Writing deterministic end-to-end tests in CI                   | Playwright / Cypress            |
+| Building a hosted scraping/agent fleet on isolated profiles    | Playwright / Puppeteer + Browserbase / Steel |
+| Want a turnkey "natural-language agent" with built-in loop     | Browser Use / Stagehand / Skyvern |
+| Want a hosted, vendor-managed agent                            | OpenAI Operator / Project Mariner / Surfer |
+| Debugging your own app from your editor without leaving your real session | **pi-chrome**                   |
+
+`pi-chrome` is **primitives**, not an opinionated agent loop. Think of it as **"Playwright for the Chrome you're already signed into"** — and pluggable under any agent framework above the line.
+
+---
+
+## The three axes you should compare on
+
+| Axis                              | Examples                                                              | What it gives you             |
+| --------------------------------- | --------------------------------------------------------------------- | ----------------------------- |
+| **1. Driver / transport**         | Playwright, Puppeteer, Selenium, CDP raw, `puppeteer-stealth`, **pi-chrome** | low-level tools (click, type, navigate) |
+| **2. Agent framework**            | Browser Use, Stagehand, Skyvern, Magnitude, Alumnium, LangGraph-with-Playwright, Operator, Mariner, Surfer | LLM loop, planning, NL API    |
+| **3. Cloud browser provider**     | Browserbase, Steel.dev, Hyperbrowser, Anchor, Browserless             | managed Chromes, sessions, quotas |
+
+`pi-chrome` is **axis 1**. You can wrap it with any axis-2 agent framework, or run it directly from a Pi agent's `chrome_*` tool calls. It explicitly does NOT compete with axis 3 — it runs locally inside *your* Chrome.
+
+---
+
+## Axis 1 — drivers (where pi-chrome lives)
+
+| Tool                              | Transport                                  | Profile                            | Browser input        | Banner when controlling            | Default detectable as bot |
+| --------------------------------- | ------------------------------------------ | ---------------------------------- | -------------------- | ----------------------------------- | ------------------------- |
+| Playwright                        | CDP (own driver)                           | throwaway by default               | always               | always ("controlled by test software") | yes (webdriver flag, automation flags) |
+| Puppeteer                         | CDP                                        | throwaway by default               | always               | always                              | yes                       |
+| Selenium                          | WebDriver / BiDi                           | throwaway                          | partial (BiDi improves) | always                          | most detectable           |
+| puppeteer-stealth / playwright-extra | CDP + patches                           | throwaway                          | always               | always                              | medium (patches flags)    |
+| Raw CDP                           | direct devtools protocol                   | either (needs `--remote-debugging-port`) | always           | always                              | yes                       |
+| **pi-chrome**                     | **Chrome extension bridge → local loopback** | **your real Chrome profile, signed-in cookies, extensions, history** | **always for input tools** | **while Chrome input is attached** | **low (real profile + Chrome input)¹** |
+
+¹ pi-chrome uses `chrome.debugger` for browser input and shows Chrome's banner like other CDP-based tools. The [`test-suite/`](../test-suite) grades browser-control behavior against common detection signals.
+
+### What makes pi-chrome different on this axis
+
+1. **Profile attach, not driver launch.** Every other driver fights cookie persistence, login walls, MFA, and extension state. pi-chrome inherits all of it because it *is* your Chrome.
+2. **Chrome input against your real profile.** Interactive tools use CDP input for reliability while still controlling the Chrome profile you already use.
+3. **Extension bridge transport.** No `--remote-debugging-port`, no throwaway Chromium. Survives Chrome auto-updates. Works alongside your normal Chrome usage.
+4. **Structured action results.** Input tools return target coordinates/tags and can include a fresh snapshot (`includeSnapshot`) so agents can verify state instead of blindly retrying.
+5. **Multi-session shared bridge.** Planner + worker + audit Pi sessions all drive the same Chrome concurrently.
+6. **Stable element uids.** `chrome_snapshot` returns deterministic uids you can pass to subsequent actions — similar to BrowserGym's `bid`, but built into the snapshot tool itself.
+
+---
+
+## Axis 2 — agent frameworks (built on top of axis 1)
+
+These wrap a driver with an LLM loop. They are **higher-level than pi-chrome** and **complementary**, not competitors.
+
+| Framework                | Driver underneath              | Approach                                                                                      | Open source     |
+| ------------------------ | ------------------------------ | --------------------------------------------------------------------------------------------- | --------------- |
+| **Browser Use**          | Playwright                     | DOM + a11y tree → LLM → action JSON. Open-source leader; widely cited on WebVoyager.          | MIT (Python)    |
+| **Stagehand** (Browserbase) | Playwright                  | Natural-language `.act()` / `.observe()` / `.extract()`; deterministic + AI mix.              | MIT (TypeScript)|
+| **Skyvern**              | Playwright + own DOM model     | Vision-first + DOM; YAML workflows for form/workflow automation.                              | AGPL (Python)   |
+| **Magnitude**            | Playwright                     | NL test authoring; QA-focused.                                                                | open            |
+| **Alumnium**             | Selenium / Playwright          | Test-author NL → agent. QA-focused.                                                           | open            |
+| **LangGraph / AutoGen + Playwright** | Playwright             | Generic agent graph + browser tools.                                                          | open            |
+| **OpenAI Operator**      | proprietary                    | OpenAI's own VLM + browser; ChatGPT-integrated.                                               | closed, hosted  |
+| **Project Mariner** (Google) | proprietary Chrome integration | Google's own VLM Chrome experiment.                                                       | closed          |
+| **Surfer 2 / Surfer-H** (H Company) | proprietary             | Hosted proprietary agent stack.                                                               | closed, hosted  |
+| **Anthropic Computer Use** | OS-level screenshots + mouse/keyboard | Broader than browser; OS-level events.                                                 | closed (API)    |
+
+**Why pi-chrome is not on this list:** it's intentionally **not an agent**. There's no LLM loop, no `.act("click the blue button")`. Pi handles the loop; pi-chrome provides the primitives. This means:
+
+- You can use pi-chrome under Browser Use, Stagehand, LangGraph, or any other agent framework (see [Interop](#interop)).
+- You don't pay for an opinion you don't want.
+- Agent improvements compound across all your workflows because the primitives stay stable.
+
+---
+
+## Axis 3 — cloud browser providers (orthogonal)
+
+| Provider          | What it sells                                            |
+| ----------------- | -------------------------------------------------------- |
+| **Browserbase**   | Managed browsers; pairs with Stagehand.                  |
+| **Steel.dev**     | Managed browsers + public agent leaderboards.            |
+| **Hyperbrowser**  | Managed browsers, session APIs.                          |
+| **Anchor Browser**| Managed browsers.                                        |
+| **Browserless**   | Managed Chrome, scraping focus.                          |
+
+**pi-chrome doesn't compete here.** It runs locally in *your* Chrome. The right framing if someone asks: *"no cloud cost, no session-handoff, no rate limits — and the agent runs against your real logged-in state."* If you need fleets of isolated Chromes in CI, you want one of these.
+
+---
+
+## Interop
+
+`pi-chrome` exposes tools that any Pi agent can call. If you want to use it from outside Pi:
+
+1. The local bridge speaks HTTP JSON over `127.0.0.1:17318` (default). The API is internal; use the Pi tool surface unless you are building an adapter.
+2. Tool surface mirrors Playwright closely (click/type/navigate/snapshot/screenshot/evaluate/wait_for) so adapter code is short.
+3. `includeSnapshot` on input tools lets agent harnesses verify state after actions.
+
+If you want a first-class pi-chrome adapter for Browser Use / Stagehand / LangGraph, file an issue with your use case.
+
+---
+
+## "But Playwright has `storageState` / Puppeteer has user-data-dir"
+
+Yes — you can export cookies and replay them, or point Playwright at your existing profile directory. In practice for agent workflows that breaks down fast:
+
+1. **OAuth + SSO** providers (Okta, Google, GitHub) often pin sessions to TLS fingerprints, device IDs, and browser-extension state that doesn't survive replay or a parallel Chrome instance.
+2. **MFA** tokens expire mid-run.
+3. **Internal admin tools** hard-pin to your real device.
+4. **Pointing Playwright at your real `user-data-dir`** requires closing your normal Chrome (Chrome won't share the profile lock). pi-chrome doesn't fight you for the profile because it lives *inside* it.
+5. **Watching the agent work** in your real window is a different UX than a hidden parallel Chrome. Demos, pair-driving, and confidence-building all want axis-1-with-attach.
+
+---
+
+## "Is this safer than CDP?"
+
+Different security boundary, not strictly safer.
+
+- **CDP-based tools** require `chrome --remote-debugging-port=...`. That port is unauthenticated and exposes the whole browser to any local process. Easy to misconfigure.
+- **pi-chrome** runs through an extension you install yourself with broad permissions (tabs, scripting, debugger, webNavigation). The bridge listens on `127.0.0.1:17318` loopback only, rejects browser-origin command requests, and keeps chrome_* tools locked until `/chrome authorize` is run in the current Pi session. **Only install the bundled extension if you trust the source you got the npm package from.**
+
+If your threat model excludes extensions with broad permissions, neither approach is a fit — you want a sandboxed CI runner.
+
+---
+
+## Public benchmarks worth knowing (for axis 2 / axis 3 comparison)
+
+Pi-chrome itself ships a benchmark suite ([`../test-suite/`](../test-suite)) of **42 primitive challenges** plus **4 hermetic BrowserGym-style long-horizon tasks** covering trusted input, pointer humanization, keyboard fidelity, drag/drop, Shadow DOM, iframes, file uploads, strict-CSP screenshot fallback and CDP eval/snapshot bypass, dynamic waits, tab lifecycle, network observability, fingerprint leaks, and agent-safety honeypots. Scoring tracks expected outcomes per challenge instead of raw PASS count, with `core`, `conditional`, and `quality` gate buckets. That's **driver-level** grading.
+
+For **agent-level** comparison (axis 2), the public benchmarks worth citing:
+
+| Benchmark        | What it measures                                  | Notes                                            |
+| ---------------- | ------------------------------------------------- | ------------------------------------------------ |
+| **WebArena** (CMU) | Hermetic, programmatic graders                  | Gold standard for reproducibility.               |
+| **WorkArena++** (ServiceNow) | Enterprise SaaS workflows             | Hardest realistic benchmark; <5% frontier.        |
+| **BrowseComp** (OpenAI) | Hard info-retrieval                        | Not saturated.                                    |
+| **Mind2Web 2** (NeurIPS '25) | Long-horizon, rubric-tree judge       | New, well-designed.                              |
+| **WebChoreArena** | Tedious cross-page workflows                     | Reflects real ops work.                          |
+| **WebVoyager**   | Live web tasks                                    | **Saturated** — 90%+ scores common; cite only as smoke test. |
+| **VisualWebArena** | Multimodal                                      |                                                  |
+| **MiniWoB++**    | Classic unit-task suite                           |                                                  |
+| **BrowserGym + AgentLab** | Research harness covering the above     | The de-facto research API; pi-chrome's snapshot uid is comparable to BrowserGym's `bid`. |
+
+Cite live leaderboards rather than hard-coded numbers; agent scores shift monthly.
+
+---
+
+## Reproducing pi-chrome's driver-level claims
+
+Run [`../test-suite/`](../test-suite) against any browser-control tool. Each challenge exposes `window.__verdict` / `window.__reason` / `window.__events`, so any tool (Playwright, Puppeteer, Selenium, Stagehand, pi-chrome) can grade itself deterministically. Headline release scoring should use the `core` gate; `conditional` depends on declared environment capabilities, and `quality` tracks adversarial/humanization regressions.
+
+```bash
+cd test-suite && python3 -m http.server 8765
+# open http://127.0.0.1:8765/ in the Chrome window the tool controls
+```
+
+If you build a competing tool, please open a PR with your scores.

+
+## Multi-session patterns
+
+`pi-chrome` shares one bridge across all Pi sessions on the same machine. Useful patterns:
+
+### Planner + Worker
+
+- **Planner session** stays high level: "find the bug, decide the fix."
+- **Worker session** runs the actual `chrome_*` tools.
+- Both see the same Chrome state because they're both pointing at your real profile.
+
+### Watcher
+
+A third Pi session can run `chrome_snapshot` periodically in `background: true` mode and post summaries via `pi-qq` — handy for long-running flows.
+
+## Chrome input
+
+Interactive tools use Chrome's real input layer by default: clicks, typing, fill, keys, hover, drag, scroll, and touch. This is reliable for:
+
+- sign-in flows
+- guarded buttons
+- audio/video controls
+- fullscreen and other user-activation checks
+- pages where DOM injection/evaluate is limited, if the agent can use screenshots + coordinates
+
+Strict CSP note: `chrome_snapshot`/`chrome_evaluate` work even on pages that disallow `unsafe-eval`, because they run via CDP `Runtime.evaluate` (not page-level `eval`/`new Function`), which is not subject to page CSP. `chrome_screenshot`, tab/navigation tools, and real input also work under any CSP.
+
+Chrome may show its debugger banner while pi-chrome is attached.

+# pi-chrome FAQ
+
+## Does this work with Brave / Arc / Edge / Vivaldi?
+
+Yes. Any Chromium-based browser that supports unpacked extensions and the `chrome.debugger` API will work. The extension is named "Pi Chrome Connector" but the source is browser-agnostic. Firefox / WebKit are out of scope (different extension models).
+
+## Will it slow my browser down?
+
+The companion extension is idle when no Pi command is in flight. It uses Manifest V3 service worker activation, so it wakes for a request and goes back to sleep. No content script is injected globally.
+
+## Does it work in Chrome incognito?
+
+By default no — extensions need explicit "Allow in incognito" permission. Toggle it on `chrome://extensions` if you want pi-chrome to see incognito tabs. We don't recommend it for sensitive work.
+
+## Will sites detect that I'm automating?
+
+Interactive controls use Chrome's real input layer via CDP, so normal user-activation gates are satisfied and input is closer to real browser use than DOM-dispatched events. pi-chrome also shapes pointer/keyboard/scroll behavior, but this is not a guarantee of undetectability. Some detectors check for the `chrome.debugger` API attached, and Chrome will show the "Chrome is being debugged" banner.
+
+The [`test-suite/`](../test-suite) grades browser-control behavior against common detection signals. Its `quality` bucket is adversarial signal, not a blanket promise that every site will treat automation as human.
+
+## Why do I see a banner saying "Pi Chrome Connector started debugging this browser"?
+
+That's Chrome's built-in warning when an extension uses `chrome.debugger`. pi-chrome uses Chrome's input layer for interactive controls, so the banner appears while attached.
+
+## Can a malicious page escape and access my other tabs?
+
+No — pages cannot directly talk to extensions. Commands flow agent → local bridge (`127.0.0.1:17318`) → extension → tab. The bridge binds to loopback only and rejects browser-origin command requests, so ordinary web pages cannot use CORS to drive it.
+
+Chrome control is also locked per Pi session until you run `/chrome authorize`; `/chrome revoke` locks it again. The remaining risk surface is **other local processes running as you** that can connect to loopback and imitate Pi. If that's in your threat model, run pi-chrome in a separate OS user account.
+
+## Can multiple Pi sessions use it at once?
+
+Yes. The first session opens the local bridge; later sessions detect it and pipe their commands through the same bridge. Each Pi session must be authorized with `/chrome authorize` before its chrome_* tools work. Each session also owns its **own** dedicated automation window (ownership is keyed by session id inside the one extension), so concurrent sessions never navigate into or close each other's tabs.
+
+## Does pi-chrome navigate my current tab?
+
+No. The first chrome_* action that has no explicit target opens a **dedicated automation window** that pi-chrome owns (falling back to a dedicated tab only if a separate window can't be created), and reuses it for the rest of the session. Your existing tabs and windows are never reused or overwritten. Pass `targetId`/`urlIncludes`/`titleIncludes` to deliberately act on a tab you already have open.
+
+The window survives `/reload` and Chrome service-worker restarts because ownership is tracked by id and mirrored to `chrome.storage.session`. It is closed when you run `/chrome revoke` and on real session end (not on `/reload`); cleanup only ever closes that session's own window/tab.
+
+**After a full browser restart**, `chrome.storage.session` is cleared by Chrome. If Chrome's session-restore reopens the old automation window, pi-chrome no longer recognizes it (its tracking is gone), so it is left alone as an ordinary window — pi-chrome will open a fresh dedicated window for the new run rather than reclaim or close the restored one. pi-chrome never closes a window it can't positively identify as its own, so a user window is never at risk.
+
+## Why ship as an unpacked extension?
+
+pi-chrome ships as an unpacked extension so the source and broad browser permissions are easy to inspect and update with the npm package. The downside: you load it manually from `chrome://extensions` and reload it after package updates.
+
+## What happens when I update pi-chrome?
+
+`/chrome doctor` will warn you if the loaded extension is older than the installed `pi-chrome`. Reload it from `chrome://extensions` to pick up the new version. Updates that add Chrome permissions may require re-approval once.
+
+## What's the install footprint?
+
+- Pi side: one extension that registers 19 tools and a few slash commands.
+- Chrome side: one unpacked extension, ~2000 LOC of plain JavaScript, no dependencies.
+
+## Can I script it without Pi?
+
+The Pi-facing tools are thin wrappers around an HTTP bridge at `127.0.0.1:17318`. You could call it directly from any process, but the API is internal and may change. If you need a stable scripting interface, file an issue and we'll consider stabilizing.
+
+## What can humans do that pi-chrome cannot?
+
+pi-chrome controls web pages through Chrome extension APIs, page inspection, screenshots, and browser input. It is not full OS-level human control. Known gaps include native Chrome/OS dialogs (print/save-as, some permission bubbles, password-manager prompts), arbitrary OS app interaction, visual CAPTCHA challenges, hardware-backed auth (passkeys/security keys/biometrics), rich multi-touch/pinch/stylus gestures, and DOM inspection inside cross-origin iframes. Some of these can still be handled with screenshot + coordinate input or user assistance, but they are not first-class deterministic workflows.
+
+## Does `chrome_evaluate` work on strict-CSP pages?
+
+Yes. `chrome_evaluate` and `chrome_snapshot` run in the page's MAIN world through CDP `Runtime.evaluate`, which is a DevTools protocol command and is **not** subject to the page's Content-Security-Policy. They work even on pages that block `'unsafe-eval'` (e.g. github.com and many bank/SaaS apps). `chrome_navigate`'s `initScript` injects at document_start via CDP and likewise bypasses CSP. `chrome_screenshot`, tab tools, and real Chrome input also keep working under any CSP.
+
+## How do I tell whether a click or type worked?
+
+Use `includeSnapshot=true` on `chrome_click`, `chrome_type`, `chrome_fill`, or `chrome_key`. The tool returns the Chrome-input result plus a fresh snapshot, so the agent can verify text, URL, visible elements, or form values before continuing.
+
+If the page did not change, take a fresh snapshot or screenshot and check for overlays, disabled controls, stale element uids, or app-side validation.
+
+## How do I attach a file to a React file input?
+
+`chrome_upload_file` — uses Chrome DevTools file-input control and fires `input` + `change` events. It does **not** open the native file picker. Works with React/Vue/Angular controlled inputs.
+
+## Can it record videos?
+
+Not yet. Screenshots only. Video recording is on the roadmap.
+
+## How do I file a good bug report?
+
+Include `/chrome doctor` output, the exact tool call, and the result envelope. If the page is public, link to it; if private, distill it into a benchmark page under `test-suite/challenges/`. See [CONTRIBUTING.md](../CONTRIBUTING.md).

+# pi-chrome browser-control benchmark
+
+Static benchmark pages for evaluating tools that let agents control Chrome. The suite has two layers:
+
+1. **Unit challenges** (`manifest.json`) — MiniWoB-style capability probes for
+   forms, scroll containers, contenteditable, files, frames, Shadow DOM,
+   network/console inspection, `isTrusted`, user activation, pointer paths, key
+   cadence, native controls, drag/drop, touch, paste, and scroll momentum.
+2. **Long-horizon hermetic tasks** (`task-manifest.json`) — WebArena /
+   BrowserGym-inspired multi-step tasks with fresh run IDs and deterministic
+   programmatic graders.
+
+## Run
+
+```bash
+cd test-suite
+python3 -m http.server 8765
+# open http://127.0.0.1:8765/ in the Chrome window pi-chrome controls
+```
+
+Each challenge page exposes:
+
+- `window.__challenge` — id
+- `window.__verdict` — `"PENDING" | "PASS" | "FAIL" | "SKIP" | "WARN"`
+- `window.__reason` — array of reasons
+- `window.__events` — raw event log for forensics
+
+`manifest.json` is the source of truth for unit-challenge metadata: category,
+gate bucket, goal, expected result per mode, prerequisites, flake risk, manual
+baseline status, and canonical tool recipe. `manifest.schema.json` documents the
+manifest shape. Recipes express tool intent; runners may need to adapt
+descriptive selectors (e.g. shadow/iframe notation), dynamic tab ids, and expand
+path placeholders like `$PWD`.
+
+`task-manifest.json` is the source of truth for long-horizon tasks: BrowserGym-style
+`taskId`, seed, viewport, goal object, difficulty tier, max steps, declared
+action subsets, reset/setup URL, validate hook, optional cheat recipe, and
+programmatic grader expression. `task-manifest.schema.json` documents this shape.
+`browsergym-action-space.json` records BrowserGym-compatible action subsets.
+
+## Modes / expected outcomes
+
+The same page can have different expected results depending on tool capability:
+
+- `synthetic` — DOM-dispatched events / framework-aware setters. Fast and quiet.
+- `trusted` — browser-trusted input, usually via `chrome.debugger`/CDP. Can show
+  Chrome's debugging banner.
+- `manual` — human baseline in same browser/profile.
+
+Expected values in `manifest.json`:
+
+- `PASS` / `FAIL` — deterministic target for that mode.
+- `CONDITIONAL` — depends on browser policy, OS, device capability, permissions,
+  or an unreleased tool primitive. Inspect `prerequisites`, `notes`, and
+  `flakeRisk`.
+
+Manual baselines are tracked separately with `manualBaseline`. `unverified`
+means the manual expectation is a target, not a recorded contract.
+
+## Gate buckets
+
+Each unit challenge has a `gate` field:
+
+- `core` — required release blocker for normal trusted-mode pi-chrome shipping.
+- `conditional` — blocks only when declared prerequisites/capabilities are present
+  (clipboard, touch, dialogs, native UI, etc.).
+- `quality` — adversarial humanization/fingerprint signal. Track regressions, but
+  do not block general ship without an explicit product decision.
+
+## Recommended unit-challenge agent flow
+
+1. Navigate to dashboard:
+   `http://127.0.0.1:8765/`.
+2. Pick mode (`synthetic`, `trusted`, or `manual`) and clear local verdicts.
+3. For each manifest row:
+   - `chrome_navigate` to `http://127.0.0.1:8765/<file>`.
+   - `chrome_snapshot` before acting; prefer snapshot `uid` over raw selector.
+   - Execute the listed `recipe`, adapting descriptive frame/shadow selectors to
+     whatever selectors/uids the tool exposes.
+   - Read:
+     ```js
+     JSON.stringify({
+       v: window.__verdict,
+       r: window.__reason,
+       e: window.__events?.slice(-20)
+     })
+     ```
+4. Return to dashboard and compare actual verdicts with expected values.
+5. Copy JSON report from dashboard for PRs or regression notes.
+
+## Recommended long-horizon task flow
+
+1. Load `task-manifest.json`.
+2. Replace `$RUN_ID` in `startUrl` with a fresh value.
+3. Navigate to the start URL and read the visible task instruction.
+4. Solve using normal browser tools only; avoid direct state mutation unless the
+   benchmark mode explicitly allows evaluate-based actions.
+5. Click **Grade now** or evaluate the task grader expression:
+   ```js
+   JSON.stringify({ v: window.__taskVerdict, r: window.__taskReason })
+   ```
+6. Record action count, observations used, tools used, verdict, and reason.
+
+## Design principles copied from browser-agent benchmarks
+
+- Prefer hermetic sites and deterministic graders over live sites and LLM judges.
+- Report action API and observation format; these strongly affect scores.
+- Use difficulty tiers: L1 atomic, L2 compositional, L3 cross-page/context-rich.
+- Include tedious cross-page memory and exact-value transfer tasks; short unit
+  probes hide these failures.
+- Keep synthetic-event-gated tests because extension bridges face failures that
+  CDP/Playwright-style benchmarks usually do not measure.
+
+## Challenge categories
+
+- `trusted-input` — browser-trusted click/key events.
+- `pointer-humanization` — paths, coordinates, movement continuity/rate.
+- `keyboard` / `focus-keyboard` — typing fidelity, modifiers, Tab flows.
+- `activation-gates` — clipboard/fullscreen/user activation.
+- `scroll` / `scroll-visibility` — wheel events, momentum, IntersectionObserver.
+- `drag-drop` — HTML5 drag/drop + `DataTransfer`.
+- `clipboard` — OS/browser paste path.
+- `native-controls` — controls that should use browser UI/keyboard semantics.
+- `frameworks` / `editing` — React-style value tracking, contenteditable.
+- `dom-complexity` / `frames` — Shadow DOM and iframe targeting.
+- `files` — file attachment to `<input type=file>`.
+- `observability` — console/network capture tools.
+- `csp` — strict Content Security Policy: screenshot/coordinate fallback (39) and the CDP eval/snapshot bypass that works under `script-src 'self'` without `unsafe-eval` (42).
+- `lazy-loading` — dynamic DOM readiness and wait behavior.
+- `fingerprint` — environment and stack fingerprint probes.
+- `agent-safety` — hidden honeypots and safe target selection.
+
+## Current challenge inventory
+
+The dashboard renders this from `manifest.json`. In brief:
+
+1. trusted click
+2. trusted keyboard
+3. webdriver/runtime flags
+4. mouse entropy before click
+5. click timing
+6. click coordinate variation
+7. pointer event properties
+8. keyboard cadence
+9. beforeinput/input order
+10. user activation gates
+11. honeypot safety
+12. fingerprint consistency
+13. focus order
+14. wheel scroll
+15. drag/drop `DataTransfer`
+16. contenteditable selection
+17. paste clipboard
+18. native select
+19. hover dwell
+20. React value tracker
+21. keyboard modifiers
+22. touch events
+23. stack trace fingerprint
+24. viewport click coordinates
+25. pointer continuity
+26. mousemove rate
+27. scroll momentum
+28. intersection visibility
+29. Shadow DOM controls
+30. iframe targeting
+31. file upload
+32. keyboard Tab navigation
+33. network/console capture
+34. dialog handling
+35. target blank popup
+36. modal focus trap
+37. autocomplete combobox
+38. SPA route change
+39. strict CSP screenshot/coordinate fallback
+40. dynamic wait/readiness
+41. explicit tab lifecycle
+42. strict CSP eval/snapshot via CDP (regression guard for the CSP bypass)
+
+## Design notes
+
+- A failure is useful only when compared to expected mode. Example: synthetic
+  `isTrusted` failing is expected and validates that the test detects quiet DOM
+  events.
+- Some tests are capability-gated. Example: touch tests should be `SKIP`/manual
+  conditional on non-touch hardware.
+- Fingerprint tests should warn before blocking. Real Chrome profiles can use
+  software WebGL in VMs, remote desktops, or policy-constrained environments.
+- `notes/bypass-ideas.md` is historical guidance for older synthetic-only
+  versions. Prefer `manifest.json` for current expected outcomes.
+- `notes/browsergym-compat.md` defines the reset/step/validate/observation/BID
+  contract for external BrowserGym-style agents.
+- `notes/runner-spec.md`, `notes/scoring.md`, and `notes/profiles.md` define
+  runner output, scoring, retry policy, and environment metadata.
