# repopedia

repopedia builds a **code knowledge graph** from a source repo (tree-sitter AST → SQLite): symbols, calls, imports, inheritance. Query it structurally instead of guessing from text search. Every answer cites `file:line`. MIT-licensed, local-first, no Docker, no server.

## When to use repopedia vs alternatives

| Question | Best tool |
|---|---|
| "Who calls `Engine.run`?" / "What breaks if I change this?" | **repopedia** (`get_callers`, `blast_radius`) — needs the call graph, text search can't do this |
| "Where is the retry logic?" (keyword-ish) | **repopedia** (`search_codebase`: BM25 + one graph hop) or ripgrep for exact strings |
| "What does this function do?" (semantics) | vector RAG / LLM reading the file — repopedia gives structure, not meaning |
| Multi-hop: "who mentors the engineer leading Project Phoenix?" | **repopedia** — joins across files via graph traversal |

Rule of thumb: **structure questions → repopedia; meaning questions → LLM; exact strings → ripgrep.**

## Quickstart

```bash
pip install repopedia
repopedia index /path/to/repo        # builds .repopedia/graph.db
repopedia blast-radius pkg.mod.func  # what breaks if this changes?
```

## MCP tools (via `repopedia mcp --repo /path/to/repo`, stdio)

| Tool | One-line |
|---|---|
| `find_symbol` | symbols by qualified/short name, each citing `file:line` |
| `get_callers` / `get_callees` | one `calls` hop each way (unresolved sites marked, not hidden) |
