三个搜索 key 改为 auth.json 中的 tavily/exa/keenable api_key 凭据， pi-web-search/auth.ts 复刻上游 resolve-config-value 语义（!command、 $VAR 插值、credential env 优先、$$/$! 转义）并在每次调用时读取， 进程环境变量与 search.env 不再被直接读取。search_config.sh 重写为 scripts/search-auth.mjs 的薄封装：加锁原子写、权限 600、保留其他 凭据条目，支持 --migrate 从旧 search.env 一次性导入。 Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com>

# pi-web-search
|
|
|
|
Unified web search and fetch for Pi. The main model only ever sees two tools —
|
|
`web_search` and `web_fetch` — provider selection happens inside the extension.
|
|
|
|
- `web_search(query, max_results?, site?, published_after?, published_before?, depth?)`
|
|
routes each query to Tavily, Exa, or Keenable using the session's current main
|
|
model (`ctx.model` + `ctx.modelRegistry.complete`), guided by per-provider
|
|
rules. Results include `details.provider` / `details.routedBy` for debugging.
|
|
- `web_fetch(urls, max_characters?)` always reads pages via Exa
|
|
(`web_fetch_exa`), degrading silently to Keenable then Tavily.
|
|
|
|
## Providers (`clients/`)
|
|
|
|
Plain `fetch` calls — no MCP adapter, no upstream extension wrappers:
|
|
|
|
- `clients/tavily.ts` — `POST api.tavily.com/search|extract`, Bearer key.
|
|
Requires a `tavily` credential.
|
|
- `clients/keenable.ts` — `api.keenable.ai`, keyless `/public` endpoints by
|
|
default, a `keenable` credential raises rate limits. Adapted from
|
|
`@keenable/pi-search`.
|
|
- `clients/exa.ts` — JSON-RPC over `mcp.exa.ai/mcp` (Streamable HTTP):
|
|
`initialize` once, cache `mcp-session-id`, `tools/call` per request, re-init
|
|
on session expiry. An `exa` credential is optional (`x-api-key` header).
|
|
|
|
Keys live in Pi's `auth.json` as one `api_key` credential per provider
|
|
(`tavily`, `exa`, `keenable`), read by `auth.ts` with upstream resolution
|
|
semantics — literal values, `$VAR`/`${VAR}` interpolation, and `!command`
|
|
indirection (e.g. `"!op read op://Vault/Tavily/key"`). `search_config.sh`
|
|
writes them (atomically, mode 600, preserving all other entries); process
|
|
environment variables are not read directly — use `"key": "$TAVILY_API_KEY"`
|
|
to indirect through env. `KEENABLE_API_URL` stays env-only, or can be stored
|
|
in the keenable credential's `env` map.
|
|
|
|
## Routing
|
|
|
|
`router.ts` asks the current model to answer with exactly one provider name,
|
|
given a prompt containing the per-provider strengths and the query's requested
|
|
filters. Decisions are cached per session (LRU, 32 entries). Failure paths are
|
|
deterministic: an unroutable answer or a dead provider falls back across the
|
|
remaining available providers — never a heuristic choice over the model.
