Conciseness

The body is lean and operational — a 5-command workflow block, terse rules, and a failure-modes list with almost no concept explanation Claude wouldn't know. Minor trimming is possible: the opening paragraph re-describes the visual signature already stated in the frontmatter ("the illuminated poster-frame look of a shop, café, cinema or metro — the setting and wall are chosen per video"), which is padding by the 4 anchor 'minor instances of over-explanation' rather than the fully lean 5.

Actionability

Fully executable guidance throughout: a copy-paste bash block with real commands and arguments (`recrop.py 0.72 0.13`, `build_video.sh $RUN/concat.txt $RUN/music.mp3 out.mp4 13.05 1.0`), a named config to copy (`scripts/config.example.json`), and failure modes with concrete fixes ("shadow_strength ~0.85", "toggle with opacity, not display", "present as a photo-tile, don't corner-flood-fill"). Matches the 5 anchor's copy-paste-ready coverage of common cases.

Workflow Clarity

The five steps are clearly ordered in the bash block with per-step comments, and validation is explicit: "Then `watch` the master (music-only, every poster legible, shadow falls across the art, end card holds)" is a concrete acceptance checklist, and the Failure Modes section supplies the error-recovery feedback loop (symptom → cause → fix). This matches the 5 anchor's explicit validation plus feedback loops; no destructive or unvalidated batch operation caps it.

Progressive Disclosure

The body is a concise overview that defers detail to clearly signaled one-level-deep references — "Schema + per-file working-dir layout are documented in `scripts/PIPELINE.md`" and "See `scripts/PIPELINE.md` for adapting `scene.html` per brand" — and every referenced bundle file exists (PIPELINE.md, config.example.json, scene.html, and all five scripts). Content is appropriately split with nothing inlined that belongs elsewhere; PIPELINE.md does not nest further references. Matches the 5 anchor.

Specificity

The description lists multiple concrete actions with comprehensive coverage: "Render a 'brand identity reveal' video from a config", plate generation, "real-DOM HTML frame-stepped via Playwright", "perspective-composited into the detected frame quad", "multiplied back onto each poster", "sequenced by FFmpeg". Every pipeline stage is named with its mechanism, matching the top anchor rather than the 'several specific actions with minor gaps' anchor at 4.

Completeness

The 'what' is fully explicit and detailed, and a 'when' clause exists ("Use for the brand-identity-reveal format"), so both are present — but the trigger is a single terse clause naming an internal format rather than concrete user-side triggers ('when the user asks for a brand identity reveal video'). This matches the anchor 'has both what and when; when could be more explicit or specific' at 4, not the 5 anchor's 'concrete trigger phrases'.

Trigger Term Quality

Relevant keywords exist ("brand identity reveal", "poster mockups", "video", "brand end card") but coverage leans on internal jargon a user would never say ("create-image-fal", "create-music-elevenlabs", "real-DOM HTML", "detected frame quad") and misses natural synonyms like "brand reveal video", "logo reveal", or "identity video". This fits the anchor 'some relevant keywords but missing common variations or synonyms' — not 4, since a user asking for a brand-reveal or logo-reveal video would not naturally match these terms.

Distinctiveness Conflict Risk

It occupies a clear niche — a specific video format with a distinctive visual signature (single poster frame, hard-cut mockup sequence, brand end card) — and the explicit "Use for the brand-identity-reveal format" trigger makes confusion with generic video or image skills unlikely. Minimal conflict risk, matching the 5 anchor.
