- Restore the step-0 interview as a mechanical gate the skill explicitly
depends on; add harness.md (per-harness question tools, limits,
fallbacks) and brief-interview.md (slots, question cards, rounds).
- Add 10 reference docs absorbed from external design skills
(accessibility, interaction-feel, elevation, color, icons, product-copy,
component-systems, critique, change-review, print-email) and extend
existing references.
- Add a review-only route and two hard-gate clauses (truncated content
reachability, three-flashes limit).
- design-gate: split tap targets into WCAG 2.5.8 and 44px contract layers,
run axe-core when available, and fix false positives found on a real
site (decorative alt="", stacked wordmark line count, url-only pages).
- lint-skill: fail if the interview gate section or its links disappear.
- Ship agents/openai.yaml and THIRD_PARTY_NOTICES.md.
