Developer Intelligence Knowledge Graph

This project contains a knowledge graph of LLM-generated documentation for a Go codebase. Instead of reading raw source files, query the knowledge graph via MCP tools.

How to use

Always prefer the knowledge graph over reading raw files. The graph contains pre-generated English documentation for every file and relationship in the codebase.

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?" → get_dependents("path/to/file.go")
• "What does X depend on?" → get_dependencies("path/to/file.go")
• "How does X connect to Y?" → find_path("file_a.go", "file_b.go")
• "What functions does X export?" → get_file_signatures("path/to/file.go")
• "Find anything about routing" → search_docs("routing")
• "What's outdated?" → get_stale_docs()
• "How big is the graph?" → get_graph_stats()

Schema

The knowledge graph has three entity types:

• File — one per source file. Has documentation (English description of what the file does), staleness (fresh or stale), prev_documentation (previous version after a merge).
• Repo — one per repository. Has documentation (project-level summary composed from file docs).
• Relationship — import edges between files. Has documentation (how the two files interact), staleness.

Staleness

When a file changes, its documentation is regenerated immediately. All downstream relationships and the repo summary are marked stale — meaning the code has changed but the doc hasn't been regenerated yet. Stale docs are still returned but flagged with [STALE].

Tips

• Start broad (get_repo_overview) then drill into specifics (get_file_doc, get_dependents).
• Use search_docs for concept-level queries ("middleware", "authentication", "error handling").
• If a doc says [STALE], the underlying code changed since it was generated. Mention this to the user.
• get_dependents is the impact analysis tool — "what breaks if I change this file?"
• File paths are relative to the repo root (e.g., echo.go, middleware/compress.go).
