Conciseness

The body is mostly operational, but the 14-step "Execution checklist (agent)" restates earlier sections nearly wholesale (session setup, dialogue gate, QA loop), the dialogue-confirmation instructions appear twice in full, and dated changelog entries sit inline ("confirmed 2026-04-09", "~~Seedance 2.0 audio+image 500 regression~~ — RESOLVED 2026-04-14") rather than in a deprecated section, which the rubric explicitly penalizes. It is above 2 because there is no teaching of concepts Claude already knows — the padding is duplication, not filler.

Actionability

Guidance is fully executable throughout: copy-paste curl ("curl -u \"$ARCADS_API_KEY:\" \"$ARCADS_BASE_URL/v1/products\""), exact JSON bodies for folders/projects, exact ffmpeg commands ("ffmpeg -f concat -safe 0 -i list.txt -c copy output.mp4", "chromakey=0xff00ff:0.10:0.05"), the npx hyperframes sequence, and per-model duration enums with word-count tables. Common cases are covered concretely, matching the copy-paste-ready anchor.

Workflow Clarity

The 14-step checklist gives a clear sequence with explicit validation checkpoints and feedback loops: the dialogue approval gate ("Never assume approval from earlier confirmations"), the credit-cost confirmation gate ("Do not generate until the user confirms"), the image-QA loop with retry cap and revised-prompt regeneration, polling to terminal status, and a 401/404/422/500 error-recovery table. Batch generation (N parallel calls) is paired with logging and post-hoc verification, matching the anchor's validate-fix-retry pattern.

Progressive Disclosure

References are one level deep and well signaled via the decision table and the "Supporting files" index, and heavy API detail is correctly deferred to reference.md — but the 335-line body still inlines multi-step workflows that belong in the referenced files (the full captions pipeline, the dialogue presentation template, duration tables), and the referenced paths (reference.md, prompting/*, ../../shared/skills/*) are absent from the provided bundle, so navigation cannot be verified end-to-end. It sits above 3 because structure and signaling are genuinely clear, below 5 because of the inlined detail and unverifiable references.

Specificity

Quotes: "Creates and retrieves AI video and image-related assets", "respects HTTP Basic auth from ARCADS_API_KEY, and polls assets/videos until ready", "Loads prompts from the bundled prompting guide and model library" — five concrete, third-person actions with no meaningful coverage gaps, matching the comprehensive-coverage anchor; a 4 would require minor gaps, which are absent.

Completeness

Both questions are explicitly answered: a concrete "what" (create/retrieve assets, auth, prompt loading, polling) followed by "Use when the user mentions Arcads, external-api.arcads.ai, Seedance..." with concrete trigger phrases — exactly the score-5 anchor shape; not 4 because the "when" is fully explicit, not merely present.

Trigger Term Quality

Quotes: "Arcads, external-api.arcads.ai, Seedance, Sora2, Veo, Kling, Nano Banana, b-roll, UGC scripts, or generating marketing creative through Arcads" — natural user phrasing plus synonyms (Seedance/Seedance 2.0, Veo/Veo 3.1) and the API hostname, matching the comprehensive-coverage anchor.

Distinctiveness Conflict Risk

Quotes: "via the Arcads external API" and "generating marketing creative through Arcads" — a clear niche with vendor- and model-specific triggers (Seedance, Nano Banana, Kling) that no generic skill would claim, matching the minimal-conflict anchor.
