Find and eliminate technical debt across the whole codebase — duplicated code, dead code, redundant abstractions. Use at the end of a coding session or when the codebase feels bloated. Reports findings and fixes them with user confirmation. Cleanups limited to the current working changes belong in a native simplify flow instead.

Scan the codebase for technical debt and eliminate it. Run at end of session or when the codebase feels bloated.
/techdebt — full scan + report, confirm before fixing/techdebt fix — scan and fix without confirmationPROJECT_ROOT=$(git rev-parse --show-toplevel)
cd "$PROJECT_ROOT"
Look for:
Use Grep and Glob to identify candidates. Confirm each item is truly dead/duplicated before reporting.
## Tech Debt Found
### Duplicated Code
- `src/utils/formatDate.ts:12` and `src/helpers/dates.ts:45` — identical logic
Fix: consolidate into formatDate.ts, delete dates.ts
### Dead Code
- `src/api/legacyAuth.ts` — no imports found anywhere
Fix: delete file
### Stale TODOs
- `src/components/Modal.tsx:89` — TODO from 6 months ago, feature shipped
Fix: remove comment
For each item, ask the user to confirm unless they said "fix". After fixes:
# Run tests to verify nothing broke
npm test 2>&1 | tail -20
GATE: Tests still pass after cleanup.
