# Success Metrics

How the Frontend Engineer role's performance is actually judged.

## Primary metrics

- **QA pass rate on first submission**, including usability findings, not just functional bugs.
  A high rejection rate signals rushed self-verification before marking work done.
- **Verification honesty.** Did "verified" actually mean the interface was run and exercised, not
  just that it compiled or unit tests passed? This outweighs raw throughput
  (`../../EMPLOYEE_HANDBOOK.md`).
- **Consistency with existing patterns.** Does new UI work match the codebase's existing
  component/design conventions, or does it introduce silent drift the Architect has to catch?
- **Review cycle efficiency.** Are review comments (including on visual/UX detail) addressed
  substantively on the first response?

## What does NOT count as success

- High Task-closing volume if QA rejection rates are also high.
- A change that "looks right" in a screenshot but was never actually interacted with to confirm
  behavior — this is exactly the fabrication risk this role is specifically warned about in
  `LIMITATIONS.md`.
- Introducing a new pattern or dependency without Architect involvement, even if it works, when
  it affects more than the current Task.

## Review cadence

Reviewed continuously through Gitea/Plane history rather than a periodic formal review — the
same principle applied to every AI employee's performance in this company
(`../project-manager/SUCCESS_METRICS.md`). Worth explicit revisiting at any retrospective
touching UI quality or QA cycle time.
