Conciseness

The body is maximally dense with zero padding: no concept explanations, and every sentence carries an operating rule (limits, durations, defaults, anti-patterns like "不无限监听，不把样本当完整历史"). Matches anchor 5: 'Lean and efficient; assumes Claude's competence; every token earns its place.'

Actionability

Commands are concrete and copy-paste ready with flags, defaults, and ranges (list --limit 20, send --conversation ... --confirm, listen --duration 1s-10m). Minor gaps keep it below 5: the generic 'tiktok-im call <resource> <action> [平台选项]' entry is underspecified and no example uses a concrete value.

Workflow Clarity

This simple skill has unambiguous single actions plus explicit validation checkpoints and feedback loops for the risky write path: preview-by-default with --confirm, ticket-guard material blocking requests before they fire, "超时/断连先核对结果，不换通道重发" (verify results before resending), and mandatory real-account verification of responses, delivery, and permissions. The destructive/batch cap at 3 does not apply because validation is present.

Progressive Disclosure

At 24 lines with no bundle files (references/, scripts/, assets/ absent) and no external references needed, the simple-skill exception applies: content is clearly organized (overview → command block → behavioral rules → routing to sibling skills) and easy to navigate. Matches anchor 5 under the under-50-lines guideline.

Specificity

The description names the domain ("TikTok私信会话" — TikTok DM conversations) but lists no concrete actions, deferring scope to an external "工具能力表" (tool capability table). This matches the anchor 'Names the domain but actions are minimal or generic' (e.g., 'Processes PDF files'), and not level 3 since no 1-2 concrete actions are stated.

Completeness

The 'what' is vague (domain only, scope deferred to a table elsewhere) and the 'when' is entirely absent — no 'Use when...' clause or equivalent trigger guidance, which caps completeness at 3 per the guidelines. It matches anchor 2: 'Has a vague what and no when'; not 1 because the domain is concretely identified.

Trigger Term Quality

"TikTok", "私信" (DMs), and "会话" (conversations) are relevant natural terms, but common variations and synonyms a user might say are missing (DM, direct message, 消息, 发消息, chat). This matches 'Some relevant keywords but missing common variations or synonyms'.

Distinctiveness Conflict Risk

"TikTok私信会话" carves a mostly distinct niche (TikTok direct-message conversations), but trigger phrasing is thin and it sits adjacent to sibling TikTok tooling (tiktok-hunter), leaving minor overlap risk. Matches 'Mostly distinct; minor overlap risk with closely related skills'; not 5 because the thin trigger terms don't clearly separate it.
