name	verify
description	Lightweight project verification. Runs typecheck, lint, prettier (auto-fix), and build. Reports pass/fail status and offers to auto-fix lint issues. Use for quick verification before commits or after changes.

Verify Project

Run the core verification suite with live progress reporting.

Progress Tracking

Use TodoWrite to create and update a todo list so the user can see progress:

- Typecheck (yarn typecheck)
- Lint (yarn lint)
- Prettier (yarn prettier)
- Build (yarn build)

Mark each todo as in_progress before running, and completed or note failure immediately after.

Steps

Phase 1 (parallel)

Run these three checks in parallel (they are independent). Mark all three as in_progress, then run the Bash commands in a single message:

• yarn typecheck
• yarn lint
• yarn prettier (always auto-format, NOT prettier:check)

After each completes, immediately mark its todo as completed (or note failure). Output a one-line status for each (e.g., "Typecheck: PASS", "Lint: FAIL - 3 errors").

Phase 2 (after Phase 1)

Mark Build as in_progress, then run:

• yarn build

Mark completed and output status.

Auto-Fix Behavior

• Prettier: Always auto-fixed (Phase 1 runs yarn prettier, not prettier:check).
• Lint: If lint fails, ask the user: "Lint found N issues. Want me to run yarn lint --fix to auto-fix?" If yes, run yarn lint --fix, then re-run yarn lint to check for remaining issues.
• Typecheck/Build: Cannot be auto-fixed. Report errors and suggest fixes.

After Auto-Fix

If lint auto-fix was applied, re-run the full verification suite to confirm everything passes.

Final Report

After all steps, output:

|------------|--------|
| Typecheck  | PASS/FAIL |
| Lint       | PASS/FAIL |
