| description | Search callers, dependents, and linked systems before changing code. |
Before editing code, check impact.
- Run
node bin/generate-graph.js when .codelookup/graph.json is absent or stale.
- Run
node bin/pre-check.js, npx codelookup-check, or local project equivalent.
- Inspect changed code callers, return contracts, schemas, and linked systems.
- Apply required cascade updates in same change.
- Run integration tests covering changed code and dependents.
If checker unavailable, use rg to trace imports, callers, and dependent tests. Report Mermaid blast radius before editing.
