## Rename Symbol
Old name: **$1**
New name: **$2**
1. Find all occurrences:
```bash
grep -rn "\b$1\b" . --include="*.ts" --include="*.tsx" --include="*.js" --include="*.jsx" --exclude-dir=node_modules --exclude-dir=dist
```
2. Categorize occurrences:
- Definition (function/class/type declaration)
- Call sites
- Type annotations
- Imports/exports
- Test files
- Comments and documentation
- String literals (flag separately - may be API contracts)
3. Show the full list. Flag any in string literals or external-facing API contracts as risky.
4. Ask for confirmation, then rename all (except flagged ones).
5. Run type check to verify:
```bash
npx tsc --noEmit
```
Report any errors introduced.
