Ask Skill — Codebase Question Router

Answer a question about the codebase by routing to the most effective tool.

Don't search files manually when a smarter tool exists.

Routing Rules

Architecture / flow / how does X work / trace a call

Use mcp__codebase-memory__trace_path or mcp__codebase-memory__get_architecture. Zero file reads. 120× fewer tokens than manual exploration.

Find / search / locate / what file / which function

Use mcp__cocoindex-code__search with a semantic query. Finds code by meaning, not exact text — useful when you don't know the exact name.

Safe to change / impact / blast radius / what breaks / risk score

Use mcp__code-review-graph__detect_changes_tool with base_branch="main". Reports: risk score 0–100, blast radius, breaking changes, dependent modules.
