Conciseness

The body is dense imperative guidance with no explanations of concepts Claude already knows — every section carries operational rules. A few constraints are repeated across sections (the post_message-vs-folded warning, the @co-creator ban, and 'don't mention overlay' each appear 2-3 times), which fits 'Efficient; minor instances of over-explanation that could be trimmed' rather than 5's 'every token earns its place'; it is well above 3 since there is no genuinely unnecessary explanation.

Actionability

Guidance is highly concrete: exact tool calls with parameter values (e.g. `cat_cafe_update_bootcamp_state(threadId, phase='phase-4-task-select')`), verbatim reply strings, a skip matrix with scripted responses, and rich-block field specs. Minor gaps remain — the 16 project-card options are categorized ('前端页面、工具脚本、小游戏、数据可视化') but never enumerated, and '给出简要计划（3-5 步）' is open-ended — matching 'Mostly executable guidance; concrete code or commands with minor gaps' rather than 5.

Workflow Clarity

The phase chain is explicitly enumerated (phase-1 → phase-11 with the sole legal phase-2→phase-4 skip), each message has an ordered step list, branching on the env-check outcome includes concrete repair commands before proceeding, the lead/teammate review-then-fix loop is defined, and ⛔ STOP markers act as explicit checkpoints. This matches 'Clear sequence with explicit validation steps; feedback loops for error recovery'. No destructive/batch cap applies.

Progressive Disclosure

No bundle files exist, and the single SKILL.md is well-organized with clear per-message sections, an iron-rules block, and tables for phase names and the skip matrix. Score 5's simple-skill exception (<50 lines) does not apply at ~230 lines, and per-phase detail (e.g. the skip matrix or Phase 7.5/10 overlay mechanics) could arguably live in one-level-deep reference files — matching 'Good structure; most content is appropriately placed; minor organization gaps' rather than 3, since nothing is buried and navigation via headers is easy.

Specificity

The description names its domain ("operator 新手训练营引导模式") but provides no concrete actions — the actual capabilities (environment check, first-project walkthrough, teammate onboarding, graduation) appear only in the body, never in the description. It matches the anchor 'Names the domain but actions are minimal or generic'; score 3 would require 1-2 concrete actions to be stated.

Completeness

It explicitly answers both parts: what ("训练营引导模式" — a guided bootcamp mode for new operators) and when ("Use when: thread 有 bootcampState", plus an explicit "Not for" exclusion). Score 5 is withheld because the 'what' is a terse mode label with no concrete capability phrases, matching 'Has both what and when; when could be more explicit' on the what-side — not score 3, since the when clause is fully explicit, not weakly implied.

Trigger Term Quality

"bootcamp", "训练营", and the natural phrase "我是新手" are relevant terms a user might say, but common variations and synonyms (新手引导, onboarding, 第一次使用/上手) are absent. This fits 'Some relevant keywords but missing common variations or synonyms' rather than 4, which expects only 'a few natural terms missing' with broader coverage.

Distinctiveness Conflict Risk

"bootcampState" / "bootcamp" / "训练营" form a clear niche trigger set, and the explicit "Not for: 非训练营线程、老用户" exclusion prevents mis-triggering on general onboarding or veteran sessions. This matches 'Clear niche with distinct triggers; minimal conflict risk'.
