Conciseness

The six-line body is lean and directive — e.g. '保存到用户操作系统的临时目录，不要保存到当前 workspace' and '改用 path 或 URL 引用它们' — with no padding and no explanation of concepts Claude already knows. Every instruction earns its place, matching the anchor 'lean and efficient; assumes Claude's competence'.

Actionability

Guidance is concrete and executable: a specific save location (OS temp directory, not the workspace), a required named section ('suggested skills' with Skill-tool invocation), an explicit redaction list ('API keys、passwords、personally identifiable information'), and argument handling. It is not 5 because no document template or structure is given, leaving the handoff's shape partly to guesswork; it is above 3 since every instruction is directly executable without pseudocode.

Workflow Clarity

This is a simple single-task skill whose core action (write a handoff document satisfying the stated constraints) is unambiguous, with a coherent implicit order. It is not 5 because minor gaps remain — no filename convention for the temp file and no checkpoint confirming the handoff is sufficient for a fresh agent to resume.

Progressive Disclosure

At under 50 lines with no bundle files (references/, scripts/, assets/ are absent) and nothing that belongs in a separate file, the body is appropriately self-contained and cleanly organized as one instruction per paragraph. It is not 5 because the body uses no section headers or labeled structure, so navigation relies on reading the whole (short) text.

Specificity

The description states one concrete action — '把当前对话压缩成交接文档' (compress the current conversation into a handoff document) — with a clear outcome ('让另一个代理接手'), matching the anchor 'names domain and 1-2 concrete actions, but not comprehensive'. It stays at 3 rather than 4 because it lists only a single action and omits what the document contains or where it is saved.

Completeness

The 'what' is clearly stated (compress the conversation into a handoff document for a successor agent), but there is no 'Use when...' clause or equivalent trigger guidance, which caps completeness at 3 per the judging guidelines. It is not 4 because the 'when' is entirely absent rather than merely implicit or imprecise.

Trigger Term Quality

Terms like '对话' (conversation), '交接文档' (handoff document), and '代理' (agent) are relevant to the domain, but common user phrasings such as 'handoff', '新会话' (new session), or '接手/继续工作' (take over / continue) are absent, matching 'some relevant keywords but missing common variations or synonyms'. It is not 2 because the present keywords are domain-specific rather than generic.

Distinctiveness Conflict Risk

The agent-handoff niche ('交接文档', '另一个代理接手') is mostly distinct, with only minor overlap risk against conversation-summarization or session-continuation skills, matching 'mostly distinct; minor overlap risk with closely related skills'. It is not 5 because no explicit trigger phrases are given to fully disambiguate it from those neighbors.
