## Developer Intelligence Knowledge Graph
This environment has access to a knowledge graph of LLM-generated documentation for your codebase via MCP tools.
**Always prefer the knowledge graph over reading raw files when answering questions about what code does or how files interact.**
### Query patterns
- "What does X do?"`get_file_doc("path/to/file.go")`
- "How do X and Y interact?"`get_relationship("file_a.go", "file_b.go")`
- "What's this project about?"`get_repo_overview()`
- "What depends on X?" / "What breaks if I change X?"`get_dependents("path/to/file.go")`
- "What does X depend on?"`get_dependencies("path/to/file.go")`
- "Find anything about routing"`search_docs("routing")`
- "What's outdated?"`get_stale_docs()`
### Staleness
Docs flagged `[STALE]` mean the code changed but the doc hasn't been regenerated yet. Mention this to the user.
### Tips
- Start broad (`get_repo_overview`) then drill into specifics.
- `get_dependents` is impact analysis — "what breaks if I change this?"
- File paths are relative to repo root (e.g., `echo.go`, `middleware/compress.go`).
