Conciseness

The body is ~20 lines with zero padding: a four-row command table and two concrete location facts ("E:/knowledge-base", "http://127.0.0.1:8001"), with no explanations of concepts Claude already knows. It matches the 'lean and efficient; every token earns its place' anchor, and there is nothing to trim that would push it toward 4.

Actionability

The body maps user phrases to intents ("查一下 xxx" → 搜索知识库) and gives a root path and API base URL, but provides no executable guidance for any operation — no API endpoint or request format for searching, no command or script for switching modes or feeding documents. This matches 'minimal concrete guidance; high-level hints but missing the specific steps to execute'; it is above 1 because the paths, URL, and exact command phrases are concrete, and below 3 because even pseudocode-level steps for the core actions are absent.

Workflow Clarity

No sequence exists for any operation: how a search is executed against the API, what document feeding (投喂) involves, or how mode switching takes effect is entirely unspecified, matching 'rough sequence present but many gaps; validation absent' (here the gaps swallow the sequence). It is not 1 because the command table does establish an unambiguous intent-to-action mapping for the simple lookup case, and the simple-skill exception to score 5 does not apply because the core actions are not unambiguous; the batch-like feeding operation also lacks any validation, which would cap this at 3 regardless.

Progressive Disclosure

This is a skill under 50 lines with no bundle files (references/, scripts/, assets/ do not exist) and no need for external references, and the body is organized into two well-labeled sections (使用方法, 文件位置), which per the rubric's simple-skill guidance earns a 5. There are no buried or nested references to penalize, and no inlined content that belongs in a separate file.

Specificity

The description names the domain ("本地知识库集成") and lists concrete actions ("文档检索、投喂、双轨模式切换"), matching the anchor for naming a domain with 1-2 concrete actions but not comprehensive coverage. It does not reach 4 because it omits several capabilities implied by the body (e.g., knowledge base statistics) and stays at a bare keyword list, and it is above 2 because the actions named are specific rather than generic.

Completeness

There is a recognizable 'what' (local knowledge base integration covering retrieval, document feeding, and dual-track mode switching) but no 'when' clause at all, which per the judging guidelines caps completeness at 3. It cannot be 4 without any trigger guidance, and it is above 2 because the 'what' is stated with concrete capability names rather than being vague.

Trigger Term Quality

Terms like "知识库" (knowledge base) and "文档检索" (document retrieval) are relevant keywords a user might plausibly say, matching the 'some relevant keywords but missing common variations' anchor. It is not 4 because natural user phrasings shown in the body ("查一下", "切换到本地知识库", "知识库统计") and synonyms/extensions are absent from the description, and it is above 2 because the keywords are domain-relevant rather than purely generic.

Distinctiveness Conflict Risk

"本地知识库" (local knowledge base) carves out a somewhat specific niche, but the description never names the concrete system involved (AnythingLLM appears only in the body) and could overlap with general RAG/search/document skills, matching the 'somewhat specific but could still overlap' anchor. It is below 4 because the distinctive dual-track trigger phrases are missing, and above 2 because it is not broadly generic like 'helps with documents'.
