Conciseness

The body is dense and assumes competence — no explanations of what scroll or libraries are, decision tables instead of prose, and detail explicitly deferred ('Conteudo denso... vive em `references/` — carregar sob demanda'), matching 'efficient; minor instances that could be trimmed'. Not 5: the filmic one-shot onus is stated twice (end of the grammars section and again as a Regras Duras row), and 'O que isto NAO e' carries some editorial rhetoric ('se reconhece de longe: mesmo diorama de argila...') that could be tightened without losing the taste guidance.

Actionability

Guidance is mostly executable for an instruction-only skill: the 8-grammar table, the 'Nunca | Em vez isso' hard-rules table, a measurable pre-build checklist (4+ device families, max two scrub acts, 8-14 viewport-heights), the `data-sc-*`/`--sc-p` contract with real HTML in references/devices.md, and a concrete token-theming CSS block in pipeline.md. Not 5: the central copy-paste artifact — 'engine/scrollcraft.js e engine/scrollcraft.css (do diretorio raiz desta skill)' — does not exist in the bundle, so the build step's key executable cannot actually be executed as written.

Workflow Clarity

The 5-passo pipeline is clearly sequenced (entrevista → brief/jornada → gramatica/gate/score → assets → construir/verificar) with a pre-build checklist and an explicit validation feedback loop at Passo 5 ('voltar ao Passo 2 pra reclassificar o beat — nao corrigir o HTML isolado'), plus an evidence-of-completion list — matching the anchor's 'clear sequence with explicit validation steps; feedback loops; checklists'. Not 4: validation checkpoints are explicit and the recovery path names where to go back to, not merely 'verify output'.

Progressive Disclosure

The ~200-line overview is well split across nine real, one-level-deep reference files, each signaled with what it holds and when to load it ('Detalhe completo... em `references/pipeline.md`', 'Ver references/worlds.md'), matching 'good structure; most content appropriately placed'. Not 5: scored against the actual bundle, the repeatedly referenced `engine/` directory is missing, `references/verify.md` and `references/taste.md` are surfaced only via PROVENANCE/pipeline.md rather than from the body's own verification sections, and GLOBAL.md/policies/ paths are unverifiable in this bundle.

Specificity

The 'what' is a single clear action — 'Projeta narrativas interativas acionadas por rolagem' — which names the domain plus one concrete capability, matching the '1-2 concrete actions, not comprehensive' anchor. It does not reach 4 because the description never mentions the other concrete actions the skill performs (build the HTML page, scrub video, pin sections, verify via screenshots), and it is above 2 because the action is domain-specific rather than generic.

Completeness

Both questions are answered explicitly: what ('Projeta narrativas interativas acionadas por rolagem') and when ('Trigger em:' followed by concrete trigger phrases), mirroring the anchor-5 example structure. Not 4: the 'when' is fully explicit with literal trigger phrases rather than merely implied or generic, which is what the 4 anchor requires improving.

Trigger Term Quality

Twelve trigger phrases give comprehensive natural coverage with synonyms in both English and PT-BR ('scrollytelling', 'scroll storytelling', 'scroll-driven', 'Apple-style landing page', 'video que roda com o scroll', 'landing page cinematografica'), directly matching the 'comprehensive coverage of natural terms including synonyms' anchor. Not 4: no commonly used variant is obviously missing; the one ambiguous phrase ('parece um template') is a conflict-risk concern, not a coverage gap.

Distinctiveness Conflict Risk

The scrollytelling niche is clear and most triggers ('Apple-style landing page', '3D scroll world', 'video que roda com o scroll') would not fire for other skills, matching 'mostly distinct; minor overlap risk'. Not 5: 'interactive landing page' and 'parece um template' are broad enough to collide with a general UI/UX or landing-page design skill — a boundary the body has to police explicitly.
