- 15 tests for config resolution, tool version, and server tool building
- 3 tests for stream wrapper (injection, dedup, non-anthropic passthrough)
- All 18 tests green
Add initial implementation for Anthropic's server-side web_search_20260209
tool as a search provider option. This includes:
- Web search provider plugin (extensions/anthropic/src/)
- Stream wrapper to inject server tool into API payload
- Provider registration in anthropic extension
- Added to bundled web search plugin list
WIP: Still needs wrapStreamFn wiring, compat flag integration,
config schema, tests, and pi-ai server tool support verification.
