Conciseness

The 373-line body carries genuine domain knowledge Claude lacks (Douyin ad-compliance rules, oral-style constraints), but the ~55-line Step 3 analysis prompt substantially duplicates references/analysis-dimensions.md (same 7 dimensions, same hook-type taxonomy), hook-type lists are repeated again in Step 5's Part B requirements, and the personal branding footer (「花叔出品 | 公众号…」) is pure padding. This fits 'Mostly efficient but includes some unnecessary explanation or could be tightened'; it is above 2 because the verbosity is duplication rather than explaining concepts Claude already knows, and below 4 because the duplication is structural, not minor.

Actionability

Commands are copy-paste ready (`uv run SKILL_DIR/scripts/download_douyin.py --urls "URL1" "URL2" --output-dir _temp/douyin-downloads`), both script-generation prompt templates are complete with clearly marked fill-in variables, output paths are specified, and failure fallbacks (manual download, MCP fallback) cover the common failure case. This matches 'Fully executable; copy-paste ready code or commands; specific examples cover the common cases'; the SKILL_DIR placeholder is explicitly instructed to be resolved first, so it is not a gap.

Workflow Clarity

The 6 steps are strictly sequenced with two explicitly flagged user-confirmation checkpoints (Step 4 「← 用户确认节点」, Step 6), a 5-item review checklist in Step 6, error-recovery fallbacks in Step 2, parallelization guidance (run_in_background=true), and two complete alternate paths (with/without competitor videos) in 快速使用. This matches the score-5 anchor's 'explicit validation steps; feedback loops for error recovery; checklists'; there are no validation gaps to drop it to 4.

Progressive Disclosure

All five referenced bundle files exist, are one level deep, and are indexed in a 参考资源 table with per-file purpose — good navigation. It is not 5 because the Step 3 analysis prompt should live in (or defer to) references/analysis-dimensions.md instead of duplicating it inline, and Step 6 cites two sibling skills by name (「视频脚本口语化审校」skill, 「ai-taste-proofreading」skill) without paths, which is a dangling reference. It is well above 3 because the split between SKILL.md, references/, and scripts/ is otherwise appropriate and clearly signaled.

Specificity

The description enumerates a concrete end-to-end pipeline — 「下载抖音视频→Gemini视频分析→爆款公式提炼→脚本+分镜生成→AI味审校」 — five specific, distinct actions rather than vague domain language. This matches the anchor 'Lists multiple specific concrete actions; comprehensive coverage'; it is not score 4 because no meaningful capability in the workflow is left unlisted.

Completeness

It explicitly answers both questions: 'what' via the named pipeline steps and 'when' via 「当用户提到…时使用此技能」 with concrete trigger phrases — the exact pattern of the score-5 anchor example. It is not score 4 because the 'when' clause is fully explicit with enumerated triggers, not merely present.

Trigger Term Quality

It lists eight natural trigger phrases users would actually say: 「抖音脚本」「爆款拆解」「竞品分析」「带货脚本」「千川素材」「种草脚本」「视频拆解」「抖音视频分析」, covering domain synonyms across both content styles (种草/千川). This matches the comprehensive-synonyms anchor; score 4 would require noticeable missing natural terms, and none are evident.

Distinctiveness Conflict Risk

The niche is clear (Douyin e-commerce short-video scripts) and most triggers are platform-specific, but 「竞品分析」 and 「视频拆解」 are generic terms that could overlap with non-Douyin marketing-analysis or video-analysis skills. This fits 'Mostly distinct; minor overlap risk with closely related skills'; not 5 because two of the eight triggers are not domain-locked, and not 3 because the dominant triggers (抖音脚本、千川素材、种草脚本) are unmistakably specific.
