Conciseness

The body is ~19 lines with zero padding: no concept explanations, no boilerplate — every sentence carries operational facts ("--record-id 是 published-track 表行 ID", "默认只取 20 条，最大 100 条", "null 不写、不覆盖历史值"). This matches 'Lean and efficient; assumes Claude's competence; every token earns its place'.

Actionability

Four copy-paste-ready commands with concrete flags cover the full command surface (check/list/fetch/daily), and the prose supplies executable specifics: the exact matching keys (完整发布 URL, notes.platform_runtime 中的创作者作品 ID), the downstream call (published-track update-metrics), write semantics (只写非负整数，真实 0 保留), and result fields (source、captured_at、分页信息). This matches 'Fully executable; copy-paste ready commands; specific examples cover the common cases'.

Workflow Clarity

The pipeline is described (在线核验当前用户 → 获取本人作品列表 → 匹配 → update-metrics) and includes real matching guardrails (只更新真实匹配的记录，没取到的返回 skipped；不用标题猜匹配；存在作者字段时再核对), but the intended order of the four subcommands is never stated, `check` and `daily` are unexplained, and there is no error-recovery/feedback loop for what is a batch database-write operation. Because this is a batch update workflow without full validation checkpoints or failure handling, it fits 'Steps listed but validation gaps' and the batch-operation cap keeps it at 3 rather than 4.

Progressive Disclosure

The skill is under 50 lines with no references/, scripts/, or assets/ directories, and it needs none — all guidance fits inline. Per the rubric's simple-skill note, a sub-50-line skill with no need for external references scores 5 with well-organized content, and the body is cleanly organized (title, command block, then a matching-semantics paragraph and an update-limits/non-goals paragraph).

Specificity

The description names its domain ("快手本人已发布作品") and exactly two concrete actions ("数据获取" and "指标回填") plus a non-goal clause ("不负责发布或其他账号数据分析"), which matches the anchor 'Names domain and 1-2 concrete actions, but not comprehensive'. It does not reach 4 because it does not list several specific actions (e.g., listing works, matching records, updating metrics are only implied), and it is clearly above 2 since the actions are concrete rather than generic.

Completeness

The 'what' is clear (fetch own published-works data and backfill metrics, with explicit exclusions), but there is no 'Use when...' clause or equivalent trigger guidance — the 'when' is at best weakly implied by the domain naming. Per the judging guidelines a missing 'Use when...' clause caps completeness at 3, and the description is not vague enough to fall to 2.

Trigger Term Quality

"快手" is a strong natural keyword a user would say, and "作品" / "指标" are relevant domain terms, but common variations users would naturally use — 播放量, 点赞/评论, 视频数据, 数据回填 — are absent. This fits 'Some relevant keywords but missing common variations or synonyms' rather than 4, since keyword coverage is thin beyond the platform name.

Distinctiveness Conflict Risk

The description carves a clear niche — one platform (快手), one account scope (本人已发布作品), one function (指标回填) — and explicitly disclaims adjacent functions ("不负责发布或其他账号数据分析"), which actively prevents wrong-skill triggering. Conflict risk with generic or sibling skills is minimal, matching the 'Clear niche with distinct triggers; minimal conflict risk' anchor; it is not a 4 because the boundary statements leave no meaningful overlap with closely related skills.
