Conciseness

The 340-line body is heavily padded with repetition: "COZE" appears 59 times, the no-local-dependency rule is restated in 前置准备, 整体流程说明, every step, and 注意事项, and each of the 10 agent sections repeats the same 角色定位/触发条件/输入要求/输出标准/协同规则 boilerplate. It does not explain concepts Claude already knows, which keeps it above anchor 1, but the duplicated boilerplate clearly matches anchor 2.

Actionability

Concrete parameters are given (30秒3-5句 copy counts, 2-5s per shot, 1080P, JPG/PNG, MP3, 25fps, 0.3-0.5s transitions, retry ≤3), but the single most important action — calling the COZE API — has no executable guidance: no endpoint, request format, command, or code example anywhere in the body. The bundle compounds this with scripts/video_composer.py and scripts/image_quality_checker.py that use the very libraries (moviepy, opencv, mediapipe, numpy) the body forbids, leaving guidance partially incomplete and internally contradicted.

Workflow Clarity

The 10-step sequence is explicit with a flow-architecture line, per-step inputs/outputs, and genuine validation checkpoints and feedback loops (质检智能体 blocks unqualified outputs, 素材预检, API retry ≤3 with 10s timeout, 瑕疵分级 rework). It misses anchor 5 due to an internal contradiction — "并行协同：字幕师、音效师可在脚本创作师输出后并行启动" (step 6-7 can run in parallel) versus "10大智能体协同：严格按顺序执行" in 注意事项 — and the repetitive restatement obscures the critical path.

Progressive Disclosure

Six references are clearly labeled with purpose in 资源索引 (usage_limit, subtitle_format, audio_format, storyboard_format, use_cases, agent_specs), but the body inlines ~30 lines of per-agent spec per step that duplicates references/agent_specs.md (366 lines covering the same 10 agents), making the SKILL.md a 340-line monolith — content that clearly belongs in the referenced file is inline. The bundle also contains 4 reference files (development_guide, mask_video_guide, quality_standards, video_specs) and 2 scripts never referenced from the body, so discovery of the bundle's actual contents is incomplete.

Specificity

The description lists several concrete pipeline actions — "从卖点提炼、分镜生图到音效字幕，一键调用COZE API自动合成高质量商品视频" plus 质检 and 数据迭代 — which goes beyond the 1-2 actions of anchor 3. It falls short of anchor 5 because marketing fluff ("一键", "彻底告别本地代码依赖", "轻松实现...全流程闭环") pads the action list without adding concrete coverage.

Completeness

Both parts are explicit: the "what" is the 10-agent pipeline ending in COZE API video synthesis, and the "when" is an explicit trigger clause — "电商运营与自媒体创作者在为美妆、家居、智能硬件等商品制作短视频时，请使用此技能". It sits at anchor 4 rather than 5 because the when-clause names the audience/context but not concrete trigger phrasings a user would actually utter.

Trigger Term Quality

It includes natural domain terms users would say — "短视频", "商品视频", "美妆、家居、智能硬件", "电商运营与自媒体创作者", "COZE API" — giving good keyword coverage. Not 5 because common variations and synonyms are missing (e.g. 带货视频/产品视频 phrasings, or output-format terms like MP4).

Distinctiveness Conflict Risk

The niche is clear — e-commerce product short-video synthesis via the COZE API — with distinct triggers tied to 商品/电商/短视频. It is not 5 because "制作短视频" overlaps with generic video-generation skills that could also trigger on short-video requests.
