It intercepts Anthropic requests before they are sent and ensures a native `web_fetch_*` tool is present for `anthropic-messages` payloads.\n\n| Case | Result |\n|------|--------|\n| API is `anthropic-messages` and no native `web_fetch_*` tool exists | injects `{ type: \"web_fetch_20260309\", name: \"web_fetch\" }` |\n| Existing native `web_fetch_*` tool exists | preserves it (no duplication) |\n| Function variants named `webfetch` or `web_fetch` are present | strips function variants and keeps native variant |\n| Non-Anthropic API payload | leaves payload unchanged |\n\nSet `PI_ANTHROPIC_WEB_FETCH_MAX_USES` (positive integer) to include `max_uses` on injected native web-fetch tools.\n\nIt also appends a system-prompt section for Anthropic sessions indicating native `web_fetch` availability.\n\n## Installation\n\nThe package targets the [`pi`](https://github.com/badlogic/pi-mono/tree/main/packages/coding-agent) coding agent. Pi loads extensions from `~/.pi/agent/extensions/`, project `.pi/extensions/`, or via the `--extension` / `-e` CLI flag.\n\n```bash\n# From npm (once published)\npi install npm:pi-anthropic-web-fetch\n\n# From git\npi install git:github.com/code-yeongyu/pi-anthropic-web-fetch\n\n# Manual placement\ngit clone https://github.com/code-yeongyu/pi-anthropic-web-fetch ~/.pi/agent/extensions/pi-anthropic-web-fetch\ncd ~/.pi/agent/extensions/pi-anthropic-web-fetch \u0026\u0026 npm install\n\n# Dev / one-shot test\npi -e /path/to/pi-anthropic-web-fetch/src/index.ts\n```\n\nAfter installation, restart pi or run `/reload` inside an interactive session.\n\n## Development\n\n```bash\nnpm install\nnpm test\nnpm run typecheck\nnpm run check\npi -e ./src/index.ts\n```\n\nThe test suite uses vitest. TypeScript is strict, Node-only, and uses ESM imports with `.js` suffixes.\n\n## Origin\n\nPorted from `packages/coding-agent/src/core/extensions/builtin/anthropic-web-fetch/index.ts` in `code-yeongyu/senpi-mono`.\n\n## License\n\n[MIT](LICENSE).\n\n## Related\n\n- [senpi](https://github.com/code-yeongyu/senpi) — the fork/runtime these extensions are extracted from.\n- [Ultraworkers Discord](https://discord.gg/PUwSMR9XNk) — community link from the senpi README.\n- [Dori](https://sisyphuslabs.ai) — the product powered by senpi under the hood.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcode-yeongyu%2Fpi-anthropic-web-fetch","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcode-yeongyu%2Fpi-anthropic-web-fetch","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcode-yeongyu%2Fpi-anthropic-web-fetch/lists"}
