Conciseness

The ~280-line body is dense and almost entirely non-generic domain procedure (square-grid geometry rationale, per-model timing syntax, dialogue capacity math at 3–4 字/秒), so it avoids explaining things Claude already knows. It sits at the score-4 anchor rather than 5 because there is noticeable repetition of identity-locking and reference-duty rules across sections 2–4, and some passages (e.g., the full storyboard-retake repair list) could be tightened without losing actionability.

Actionability

Guidance is highly concrete for an instruction-only skill: canonical "[Image 1]" reference syntax, a fixed annotation color legend (红色=主体运动、蓝色=摄影机运动…), numeric pacing rules (20÷4=5 字/秒 worked example, 0.3–0.8 秒 first-line entry), and exact grid mappings (2–4 格→2×2，5–9 格→3×3). It stops short of the score-5 anchor because no single complete example prompt (one full asset-sheet or video-segment output) is shown, leaving a minor gap between the structural rules and a copy-adaptable exemplar.

Workflow Clarity

The process is explicitly sequenced — §1 fact contracts → §2 asset sheets → §3 storyboards → §4 video prompts (A–E order) — and closes with a §5 pre-submission self-check of fifteen explicit validation questions. It also includes error-recovery loops (e.g., retake guidance for 串脸/复制角色, and "若实际成片首句明显延迟或第二句缺失，先改首帧和动作/对白时序…"), matching the score-5 anchor of clear sequence, explicit validation, and feedback loops.

Progressive Disclosure

There are no bundle files at all (no references/, scripts/, assets/), and all ~280 lines — including separable material like Seedance 2.0/2.5 model-specific syntax and the detailed dialogue-capacity accounting rules — are inlined in SKILL.md. Section headers are clear, but this matches the score-3 anchor ("content that should be separate is inline") rather than 4, since well-structured inline monolith is exactly what the under-50-line exception does not cover.

Specificity

The description lists multiple concrete deliverables — "编译制作级视觉资产图、电影分镜图和参考生视频 Prompt" — and enumerates subtypes ("角色身份板/设定图、关键帧或多宫格分镜、短片动作节拍、R2V/I2V/T2V 提示词") that comprehensively map to the skill's actual scope. It matches the score-5 anchor (multiple specific concrete actions, comprehensive coverage) rather than 4, since no deliverable type from the body is left out.

Completeness

It explicitly answers both questions: the "what" ("为 Creator 编译制作级视觉资产图、电影分镜图和参考生视频 Prompt") and an explicit "when" clause with concrete triggers ("适用于…尤其适合要求角色一致性、镜头语言…的任务") plus explicit exclusions ("不用于纯素材剪辑、只查询模型参数，或只评价已经生成的成片"). This matches the score-5 anchor with concrete trigger phrases and clear negative boundaries; the '适用于/尤其适合' clause is a fully explicit trigger equivalent, so the missing-'Use when' cap does not apply.

Trigger Term Quality

Natural trigger terms are present ("角色一致性、镜头语言、参考图职责、Seedance 时间段或声音设计", plus "多宫格分镜" and "关键帧"), giving good keyword coverage. It falls short of the score-5 anchor because common variations a user might say are missing (e.g., 概念图/三视图, plain-language 图生视频/视频提示词 synonyms beyond the I2V/T2V abbreviations).

Distinctiveness Conflict Risk

It occupies a clear niche (production-grade image/video prompt compilation) with distinct triggers (R2V/I2V/T2V, Seedance, 分镜/身份板) and explicit non-goals ("不用于纯素材剪辑、只查询模型参数，或只评价已经生成的成片"), which minimizes overlap with generic image, video, or editing skills — matching the score-5 anchor of a clear niche with minimal conflict risk.
