Conciseness

The body is dense tabular data ("3晚，可加晚，不可减晚", "每团8人") with zero concept explanations or padding, and the closing scope note "每日安排只写到框架这一层，不写具体餐馆、景点开放时间或价格" efficiently sets boundaries. Every token earns its place.

Actionability

Guidance is concrete: "高铁二等座或经济舱", "单程超过6小时的，首末日为交通日", "接送站（可加购）" give executable constraints and add-on options. Not a 5 because departure cities are unspecified, lodging is only loosely defined ("经济型酒店或精品青旅"), and no total price is given — minor gaps for a spec whose job is answering customer questions.

Workflow Clarity

This is a single-purpose reference skill, and the daily framework ("第1天…第2天…第3天…加晚的每一天…最后一天") is an unambiguous, clearly sequenced structure; no destructive or batch operations exist, so no validation checkpoints are needed. The simple-skill exception applies.

Progressive Disclosure

Sections (包含/不含/目的地清单/每日安排框架) are well organized and the skill is self-contained and under 50 lines. Not a 5 because "（按 SOP 选择矩阵）" points to an external artifact that is neither bundled nor explained — an unclear reference and minor organization gap.

Specificity

The description enumerates six concrete content items — "基础3晚", "适用对象、包含与不含", "目的地清单", "每日安排框架", "人数上限" — plus the product code HL-P-01. It lists several specific items with minor gaps, but describes contents rather than concrete actions/capabilities, so it is not a 5.

Completeness

The 'what' is explicit and specific (a product spec covering nights, inclusions/exclusions, destinations, itinerary framework, group size), but there is no 'Use when…' clause or equivalent trigger guidance, which caps completeness at 3 per the judging guidelines. Not a 2 because the 'what' is clear, not vague.

Trigger Term Quality

Relevant domain keywords are present ("经济游", "产品说明", "HL-P-01"), but common natural variations a customer or agent would actually say (e.g. 低价游, 穷游, 特价, 省钱) are missing, matching the 'some relevant keywords but missing synonyms' anchor rather than the good-coverage anchor.

Distinctiveness Conflict Risk

"海岚旅行经济游产品说明（HL-P-01）" names a unique company and product code, giving a clear niche with minimal generic conflict. Not a 5 because it lacks explicit trigger phrases to distinguish it from sibling product skills (e.g. comfort/premium tiers HL-P-02+) in the same line.
