| # Context: Code Signals (Static Code Inspection) | |
| ## What it is | |
| A static code inspection capability (`code_signals_search_tool`) used **only to resolve ambiguity about a repository's purpose** — i.e., when README and SDE context are insufficient to determine relevance. Hosted on the `Code_Signal` MCP server (`developing-purple-wallaby.fastmcp.app/mcp`). | |
| ## Role in the pipeline | |
| - **Step 4 (conditional):** invoked only when README and SDE context cannot determine relevance. The agent references file paths or function names and must NOT include full code excerpts (read-only inspection; see `guardrails/read-only-no-execution.md`). | |
| ## Specification status | |
| The tool's input/output schema is confirmed by the deployed tool interface; see `tools/code_signals_search_tool/input-output.md`. | |
