Conciseness

The body avoids explaining concepts Claude already knows and stays on service-specific rules, but the consent/authorization theme is restated many times across sections ("prior human authorization", "Registration alone does not authorize...", "Joining or installing this skill is not publication permission", "Never expand approval or treat silence as consent", "the owner's existing explicit authorization"), and long dense paragraphs like the registration/handle one could be tightened. This fits 'mostly efficient but includes some unnecessary explanation or could be tightened' rather than the 'several padded sections' of a 2, since each repetition carries some new context.

Actionability

Concrete, executable guidance dominates: named endpoints ("GET /api/v1/feed?q=YOUR_TECHNIQUE", "POST /api/v1/saves" with payload {"kind":"post","id":"PUBLIC_ID"}), a handle rule ("3–24 lowercase letters, digits or underscores"), a 409-retry rule, and an Idempotency-Key convention. It stays at 4 rather than 5 because the agent credential's transmission format (e.g., Authorization header) and example response shapes are never specified, leaving minor gaps before the guidance is fully copy-paste ready.

Workflow Clarity

The body sequences the multi-step flow clearly — search/review sources, join only with authorization, save/recommend, publish only within approved scope — and includes explicit checkpoints and recovery loops: "A 409 requires another handle", "Reuse a stable Idempotency-Key after a publication timeout", and the service-unavailable fallback "continue the owner's work and state that limitation". It falls short of 5 because some verification steps are stated as principles rather than explicit procedural checkpoints (e.g., the publication review is described but not sequenced as a validate-then-act step).

Progressive Disclosure

The single-file skill is well organized with clear section headers, and it defers deep detail to well-signaled one-level-deep remote documents ("read https://reels.1human.tech/discover.md", "read https://reels.1human.tech/join.md and the protocol") rather than inlining them; no bundle files exist and no local paths are referenced. It is a 4 rather than 5 because over 50 lines of inline policy detail — particularly the ~15-line registration/password onboarding section — could be split out to keep SKILL.md a leaner overview.

Specificity

The description lists three concrete actions — "Find animation and video references on 1human", "consult a human-agent shared library", and "contribute public creations only with prior owner permission" — which matches the 'several specific actions; minor gaps in coverage' anchor. It is not comprehensive (saves, follows, comments, feed search, and recommendations from the body are absent), keeping it below 5, while the presence of multiple concrete actions puts it above the '1-2 concrete actions' anchor at 3.

Completeness

The 'what' is clear (find references, consult a shared library, contribute creations with permission), but there is no 'Use when...' clause or equivalent explicit trigger guidance anywhere in the description, which caps completeness at 3 per the judging guidelines. It sits at the 'clear what, when missing or only weakly implied' anchor rather than 4, which requires an explicit — even if imperfect — 'when' statement.

Trigger Term Quality

It includes natural terms a user would say — "animation", "video", "references", "creations" — giving good keyword coverage, but misses common variations and synonyms used in the body itself such as "motion", "motion effect", "generative art", and "short video". This fits 'good keyword coverage; a few natural terms missing' rather than the comprehensive synonym coverage of a 5.

Distinctiveness Conflict Risk

The phrases "on 1human" and "human-agent shared library" tie the skill to a specific service and niche, making it mostly distinct with only minor overlap risk against generic animation/video-creation skills. It falls short of the 5 anchor's 'distinct triggers; minimal conflict risk' because the leading terms "animation and video references" could still plausibly fire for unrelated video or stock-footage requests.
