- 根包恢复 file:./pi-subagents 依赖与 extensions/subagents.ts 加载 （排在 permission-system 之后、Tool Search 之前），并刷新根锁文件； Agent / get_subagent_result / steer_subagent 权限设为 allow， 子 Agent 内的实际操作仍逐个经权限系统并转发主会话。 - 新增 config/prompt/subagent/：执行者角色 preamble 与组合包自带的 general-purpose / Explore / Plan 定义（替换上游内置，去掉 bash find 冲突规则与写死的 Haiku 模型）。 - pi-subagents 新增 basePrompt / bundledAgentsDir / excludedExtensionPaths 选项：子 Agent 不再嵌入父会话提示词，身份标记置于开头；子会话排除 pi-ask-user。未传选项时保持上游行为。 - system-prompt.ts：customPrompt 自带开场白时不再覆盖（修复子 Agent 角色 与 <active_agent> 身份被抹掉）；仅凭 customPrompt 上的 <active_agent> 识别子会话，routing 规则支持 scope，sections 支持 subagentExclude （子会话去掉 memory_policy 与 chrome_profile_bridge）。 - pi-hermes-memory：子会话只读，记忆/skill 写入工具返回错误，后台整理、 纠错检测、会话 flush 与索引写入全部跳过。 Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com>

/**
|
|
* subagent-mode.ts — subagent sessions are read-only for memory and skill
|
|
* writes. All automatic write-related work (background review, correction
|
|
* detection, session flushes, session indexing) is skipped as well.
|
|
*
|
|
* A child session is identified by the `<active_agent name="..."/>` identity
|
|
* tag that pi-subagents stamps into every child prompt
|
|
* (permission-system-bridge.ts): the tag arrives via
|
|
* `systemPromptOptions.customPrompt`. The tag is only trusted on that field —
|
|
* never in the rendered system prompt, which a main session can legitimately
|
|
* contain through project docs.
|
|
*
|
|
* Membership is tracked per session by its sessionManager identity: the same
|
|
* process hosts the parent and its children concurrently, so a global boolean
|
|
* would let a child's turn flip the parent's session into read-only mid-turn.
