Anthropic native web search extension for the [pi coding agent](https://github.com/badlogic/pi-mono/tree/main/packages/coding-agent).

This package is the standalone extraction of senpi's former builtin `anthropic-web-search` extension.

Behavior

The extension does not register a new tool. It intercepts Anthropic requests before they are sent and ensures a native `web_search_*` tool is present for first-party Anthropic `anthropic-messages` payloads.

Case	Result
API is `anthropic-messages` on `api.anthropic.com` (or `compat.supportsWebSearch: true`) and no native `web_search_*` tool exists	injects `{ type: "web_search_20250305", name: "web_search", max_uses: 8 }`
Existing native `web_search_*` tool exists on a supported endpoint	preserves it (no duplication)
Function variant named `web_search` is present on a supported endpoint	strips function variant and keeps native variant
Anthropic-compatible endpoint without `compat.supportsWebSearch`	strips native `web_search_*` tools; leaves function-tool `web_search` untouched
Non-Anthropic API payload	leaves payload unchanged

`max_uses` is hardcoded to `8`, matching Claude Code/free-code's native web search schema. Optional domain filters can be supplied with comma-separated environment variables:
