The leaf PR. Replaces the placeholder SKILL.md from PR 1 with the real
5-step workflow that loads the per-topic references on demand
(skill-creator's progressive-disclosure pattern), and adds a top-level
orchestrator that runs every tier and reports a pass/fail summary.
SKILL.md changes:
- Frontmatter unchanged from PR 1 (already covers the trigger phrases
and out-of-scope cases)
- Body rewritten as a 5-step workflow:
1. Lint (load escape-hatch.md if blockers)
2. Plan (load api-map.md, then per-topic references on demand)
3. Generate (HF index.html with paused GSAP timeline)
4. Validate (render_diff.sh against per-tier threshold)
5. Document gaps (TRANSLATION_NOTES.md if needed)
- Includes a "Source contains -> Load reference" table so the agent
only loads the references the source actually needs
- Documents the validated baseline numbers (T1 0.974, T2 0.985,
T3 0.953, T4 8/8) so reviewers can reproduce
- Calls out the critical Remotion encoder config (PNG + BT.709) that
avoids the ~0.05 SSIM hit from yuvj420p vs yuv420p
Orchestrator (assets/test-corpus/run.sh):
- Iterates tier-1-* through tier-4-* directories
- T1-T3: setup -> lint -> npm install (lazy) -> render Remotion ->
render HF -> SSIM diff at the fixture's expected threshold ->
generate strip on failure
- T4: validate.sh (lint-only)
- Emits run-report.json with per-tier pass/fail and aggregate counts
- Accepts a single-tier argument for fast iteration: ./run.sh tier-1-title-card
Validated end-to-end on a clean checkout:
▶ tier-1-title-card → mean SSIM 0.9739 (≥ 0.95) ✓
▶ tier-2-multi-scene → mean SSIM 0.985292 (≥ 0.95) ✓
▶ tier-3-data-driven → mean SSIM 0.952941 (≥ 0.9) ✓
▶ tier-4-escape-hatch → 8/8 cases ✓
passed 4/4, failed 0, skipped 0
Closes the 7-PR stack: scaffold, eval harness, 4 tiers of corpus,
references, and now the SKILL.md body that ties everything together.
