name: ask description: Route a codebase question to the right tool — structural graph, semantic search, or risk analysis. Use when you need to find or understand code without knowing exact file names.

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.

General code question (narrow, specific file, no plugin fits)

Read the file directly. Grep for the symbol.

Decision Logic

1. Contains architecture/flow/trace/how/explain → codebase-memory-mcp
2. Contains find/search/locate/where/what file → cocoindex-code
3. Contains safe/impact/blast/breaks/risk/change → code-review-graph
4. None of the above → read directly

Answer Format

• Tool used and why
• Finding (file path + line if applicable)
• Surprising cross-module connections revealed by the graph (if any)

If no tool gives a clear answer, fall back to reading relevant files.
