Conciseness

The body is extremely dense and operational — exact paths, flags, env vars, no conceptual filler Claude already knows — but the clarification that the generic pipeline is not a fallback and that type workflows only cover Stage 1–2 is repeated three times (the three-layer table note, the Stage chain intro, and the gate discipline bullet), and the story-develop intake explanation appears twice. That is noticeable redundancy that could be tightened, matching anchor 3 rather than 4.

Actionability

Guidance is fully concrete and executable: exact subcommand compositions ("assemble --manifest segments.json --verify-fps 25 --expect-durations slots/shotdur.json", "clip-trim --pre-buffer 0.5", "normalize --locked-audio"), exact deliverable paths, named env vars with routing and exit-2 behavior, and explicit deferral of parameter detail to tool docs. Instruction-only skill whose guidance is copy-paste actionable across the common cases.

Workflow Clarity

The Stage 0→15 chain is explicitly sequenced with two hard gates (GATE A text, GATE B materials) that mandate stopping for approval, validation checkpoints with numeric thresholds (self-eval <3 必返工, slideshow_risk ≥4.0 fail, verdict=pass to continue), feedback loops (rework caps of 3, wall-time limits with escalation instead of silent spinning), and a decision audit trail. This matches the anchor-5 example's validate-fix-retry discipline.

Progressive Disclosure

The three-layer structure is declared up front and references are one level deep and clearly signaled ("见 workflows/story-develop.md", "读 tools/avatar/SKILL.md", "见 references/edit-audit.md"), but none of the referenced files (workflows/*.md, tools/*/SKILL.md, references/edit-audit.md, AGENTS.md) exist in the skill bundle, so navigation cannot be verified and is likely broken as shipped. Detail that could live in reference files (Stage 12 combination recipes, env dependency routing) is also inlined, keeping this at anchor 3.

Specificity

The description "视频制作专家技能包" is a bare domain label (video production) with no action verbs or capability statements whatsoever. The domain is concrete, so it clears anchor 1, but it lists zero concrete actions, below anchor 3's "1-2 concrete actions".

Completeness

It provides only a vague 'what' (an expert skill pack for video production) and contains no 'when to use' guidance at all — exactly anchor 2 ("Has a vague 'what' and no 'when'"). The guideline caps completeness at 3 for missing 'Use when...' clauses, and this is below even that since the 'what' carries no concrete actions.

Trigger Term Quality

The only keyword is "视频制作" (video production) — one generic term with no natural user phrasings, synonyms, or scenario triggers (e.g. "做个视频", "剪个片子", "短视频"). Matches anchor 2's "one or two generic keywords; missing the natural phrases users say".

Distinctiveness Conflict Risk

Video production is a recognizable niche, but the bare label could overlap with the sibling video skills the skill itself names (`video-edit`, `talking-head-cut`, platform publishing packs), matching anchor 3's "somewhat specific but could still overlap with similar skills". Not 4: no distinct triggers are stated to disambiguate.
