Conciseness

The ~45-line body is lean with no concept explanations, but the trigger phrases appear twice (intro list and the 执行原则 mapping) and the 自动化 section partially re-states the one-sentence-entry idea, so a few tokens could be trimmed. Not 5 because of this minor duplication; not 3 because there is no unnecessary explanation or padding beyond it.

Actionability

Concrete, executable orchestration guidance: an explicit phrase→time-range mapping table, sequenced sub-skill invocations with paths (e.g. '执行 [daily-papers-fetch](../daily-papers-fetch/SKILL.md)，传入时间范围'), and a specified final report. Not 5 because '检查通过' and how the time range is passed to each sub-skill are left unspecified; not 3 because the guidance is genuinely executable, not pseudocode or high-level hints.

Workflow Clarity

Clear 5-step sequence with an explicit inter-stage gate ('只有当前阶段的预期文件已生成且检查通过，才进入下一阶段') and failure handling ('记录阶段和原因，保留已完成产物'). Not 5 because the check itself is never operationalized (which files, what check) and there is no retry loop or user-facing failure report — step 5 only covers the success path; not 3 because the validation checkpoint is explicit, not implicit.

Progressive Disclosure

A short, well-sectioned overview (Language / 执行环境 / 执行原则 / 重要约束 / 自动化) that delegates all actual work one level deep via clearly signaled references to the three sub-skills and shared files; nothing that belongs elsewhere is inlined. The sibling paths (../_shared/*, SKILL.en.md, ../daily-papers-*/SKILL.md) are cross-skill references outside this bundle, so the delegation structure itself is what is scored here.

Specificity

Names the domain and several concrete actions — 'Recommend today's papers or papers from the past N days/week; run discovery, review, and priority-paper notes' plus '论文抓取、推荐生成、重点论文笔记' — but the actions are pipeline stage names without saying what they produce. Not 5 because coverage has minor gaps (no mention of outputs/artifacts); not 3 because more than 1-2 concrete actions are listed.

Completeness

Explicitly answers both what ('run discovery, review, and priority-paper notes', '自动串联论文抓取、推荐生成、重点论文笔记三步') and when ('English triggers: ...'; '用户说…时使用') with concrete trigger phrases in both languages, in third-person voice. Matches the anchor for clearly and explicitly answering both; not 4 because the 'when' is explicit and specific, not merely present.

Trigger Term Quality

Good bilingual coverage of natural phrases a user would say: 'recommend papers', 'daily papers', 'papers from the past week' and 今日论文推荐 / 过去3天论文推荐 / 过去一周论文推荐 / 最近3天论文 / 看看这周有啥论文 (including a casual synonym). Not 5 because English coverage misses common variations like 'past 3 days papers' or 'recent papers'; not 3 because synonyms and multiple time-range variants are present.

Distinctiveness Conflict Risk

A clear niche (one-sentence daily-paper-recommendation pipeline entry) with distinct umbrella trigger phrases, but the ecosystem contains three closely related sub-skills (fetch/review/notes) whose triggers could overlap, and the boundary clarification lives in the body rather than the description. Not 5 due to this minor overlap risk with closely related skills; not 3 because the triggers are specific and the orchestrator role is stated.
