Use these tools before dumping whole files or grepping the tree.

1. If .codegraph/ exists, run codegraph explore "<symbol or question>" (or the CodeGraph MCP tools).
2. If graphify-out/graph.json exists, use Graphify (graphify explain, graphify path, or the Graphify MCP).
3. Regenerate Graphify with graphify extract . --backend deepseek --no-cluster (DeepSeek is the global LLM). Rust workspaces also pass --cargo.
