Conciseness

The ~10-line body is lean and operational: every sentence adds information Claude would not infer (config field location, call format, receipt semantics, failure handling). It assumes Claude's competence with no padding or background explanation, matching the "every token earns its place" anchor.

Actionability

Guidance is mostly executable — the exact config field (`media` in config.json), a concrete call template `message(action="send", media="...")`, and explicit status values to act on. It stops short of a 5 because the accompanying-text `message` parameter is only described in prose rather than shown in the call signature, leaving a minor gap.

Workflow Clarity

As a simple single-action skill the flow is unambiguous (check config, configure if empty, send, then interpret the receipt), and it includes a feedback loop for `failed`/`unknown` states (retain receipt, query, do not blindly resend). It is not a 5 because "查询结果" does not specify how to query the result, leaving that checkpoint's mechanism implicit.

Progressive Disclosure

The skill is under 50 lines, needs no external references, and no bundle files exist, so containing everything in a short, logically ordered SKILL.md is the correct structure. Per the simple-skill guidance, this matches the top anchor: well-organized, self-contained, easy to navigate.

Specificity

The description names the domain and one concrete action — "Send configured product demo material" — but lists no other capabilities, matching the anchor for 1-2 concrete actions without comprehensive coverage. It is not a 4 because no additional specific actions (e.g., what happens after sending, which channels) are enumerated.

Completeness

It clearly answers both "what" (send configured demo material) and "when" (three explicit trigger conditions), which satisfies the both-present anchor. It falls short of a 5 because the trigger phrases are abstract restatements of intent rather than the concrete, literal phrasings users would actually say.

Trigger Term Quality

Triggers like "ask about concrete usage", "want to understand the product", and "need a visual reference" are relevant scenarios but are abstract paraphrases rather than natural phrases users say, and common synonyms such as "demo", "example", or "show me" are missing. This matches the anchor for some relevant keywords while missing common variations, rather than the good coverage of a 4.

Distinctiveness Conflict Risk

The niche — sending pre-configured demo media — is a distinct action with mostly distinct triggers, matching the "mostly distinct; minor overlap risk" anchor. It is not a 5 because triggers like "want to understand the product" could overlap with general product-explanation or onboarding skills.
