Conciseness

The body is mostly efficient (imperative bullets, dense tables, no explanations of concepts Claude already knows), but the fal.ai model guidance is restated three ways — the 'Regra Default' table, the full model pricing table, and the 'Decisao rapida' tree — and it embeds time-sensitive pricing ('atualizado 2026-05', '$0.020/img') outside any deprecated/reference section. This matches 'mostly efficient but could be tightened'; not 4 because the triplicated model info and volatile pricing are real trimming targets.

Actionability

Fully executable, copy-paste-ready commands are given: 'node scripts/generate-image.mjs --prompt "minimalist hero, blue gradient" --aspect 16:9 --out public/hero.jpg' with --ref, --model, --list variants, auth env vars (FAL_AI_API_KEY), and concrete output-path preferences. Model defaults, overrides, and cost estimates cover the common cases — the top anchor.

Workflow Clarity

The workflow is clearly sequenced: an ordered 5-step context analysis, a pre-generation checklist, decision rules (t2i vs i2i), and an explicit validation feedback loop — 'abrir o arquivo gerado e confirmar visualmente... Se nao corresponder, ajustar o prompt... e regenerar. Nunca commitar um asset que nao foi aberto ao menos uma vez.' Evidence-of-completion and handoff checklists close the loop, matching the explicit-validation anchor.

Progressive Disclosure

References are clearly signaled and one level deep ('Ver docs/skill-guides/image-generator-models.md (carregado sob demanda)'), but no bundle files exist (no references/, scripts/, assets/) so every referenced path — scripts/generate-image.mjs, models/image-models.json, the model guide — lives outside the skill, and a ~40-line pricing table the body itself says is documented more granularly elsewhere is inlined. This sits between 'content that should be separate is inline' (2) and 'good structure, references mostly clear' (4).

Specificity

The capability statement is 'Skill para geracao e adaptacao de assets visuais' — the domain plus two concrete actions (generate, adapt/derive existing images), with asset types enumerated. It matches the 'names domain and 1-2 concrete actions' anchor; a score of 4 would require several specific actions in the capability statement itself, and the concrete operations like 'remover fundo' appear only as triggers, not stated capabilities.

Completeness

It explicitly answers both: what ('geracao e adaptacao de assets visuais') and when ('Use quando o projeto precisar de hero image, background, ilustracao, icone, favicon, mascote ou derivacao de imagem existente'), plus a concrete 'Trigger em:' phrase list. This matches the top anchor; a 4 would require the 'when' to be less explicit than this.

Trigger Term Quality

The trigger list 'gerar imagem, criar imagem, hero image, background image, favicon png, icone, mascote, illustration, remover fundo, transparent icon, tauri icons' covers natural phrases users would say, in both Portuguese and English, including synonyms and a file format — matching the comprehensive-coverage anchor. Only trivial omissions (e.g., 'logo', 'OG image') keep it from being perfect, which is not enough to drop to 4.

Distinctiveness Conflict Risk

The niche (visual asset generation/adaptation) is clear and triggers are image-specific, but 'favicon' is listed as a trigger even though the body delegates favicons/OG/PWA assets to skill 36 (Web Asset Generator) — a minor overlap risk with that closely related skill. Not a 5 (minimal conflict) because of this favicon/social-card overlap; clearly not a 3 since the skill's core scope is unmistakable.
