name	CodeLookup
description	Forces AI Agent to search for callers, dependents, and linked systems before making changes.

Always check impact before changing codebase. Code changes can break dependent systems. Follow this checklist.

Action Protocol

BEFORE editing, creating, or deleting code (functions, classes, files, variables, tables, config):

1. Run Dependency Pre-Check:

   • Run workspace local node bin/pre-check.js (or global npx codelookup-check / local npm run check) to scan Git changes, trace dependencies, and map the blast radius.
   • If .codelookup/graph.json does not exist or is outdated, run node bin/generate-graph.js first.
   • Always output the generated Mermaid blast radius flowchart in your response analysis.

2. Verify Callers:

   • Inspect files identified by the pre-check tool.
   • Trace contract, return type, schema, or signature changes.

3. Plan Cascade Updates:

   • Ensure all affected callers and linked systems are modified in the same change step. No partial commits.

4. Run Integration Tests:

   • Run tests covering both the modified file and its dependent files.
