Activation Contract

Use before answering or changing structural codebase questions.

Hard Rules

• Resolve the project root, confirm it is a project, then check .codegraph/.
• Initialize once only when the index is missing in a real project.
• Prefer codegraph_explore; use codegraph explore only if MCP is unavailable.
• Do not use administrative/destructive lifecycle commands in ordinary work.

Execution Steps

1. Run git rev-parse --show-toplevel || pwd.
2. Check <root>/.codegraph/; if absent, run codegraph init <root>.
3. Ask one focused explore question for symbols, path, callers/callees and blast radius.
4. Fall back to filesystem search only if CodeGraph fails; state the fallback.

Output Contract

Return the indexed evidence, call path/blast radius, and affected files. Do not claim structural facts from intuition.
