The body is mostly efficient, command-dense guidance that does not lecture Claude on known concepts, but it repeats the same `transition ... verify-fail` block and '立即执行' directives across Steps 1, 1b, 2a and 2b and could be tightened — placing it at 'mostly efficient but could be tightened' rather than the lean level-3 anchor.

It provides fully executable, copy-paste-ready commands (`node "$COMET_STATE" check/scale/transition/set ...`, `git diff --stat "$BASE_REF"...HEAD`) with concrete parameters and shell snippets, matching the 'fully executable code/commands; copy-paste ready' anchor; it is well above the pseudocode/incomplete level 2.

Steps are clearly sequenced (0a→0b→1→1b→2a/2b→3→4) with explicit validation checkpoints (entry check, pass/fail decision block, exit conditions, phase guard) and a real feedback loop with a 3-retry cap, satisfying the 'clear sequence with explicit validation steps; feedback loops for error recovery' anchor.

External references are clearly signaled and one level deep (`comet/reference/scripts.md`, `decision-point.md`, `dirty-worktree.md`, etc.), but the SKILL.md itself is a long, fairly monolithic procedure with substantial inline detail (scale-assessment rules, dirty-worktree special handling) that could live in referenced files — matching 'some structure but content that should be separate is inline' rather than the cleanly split level-3 anchor. No bundle files exist under references/scripts/assets to verify the referenced paths against.

The description lists multiple concrete actions — '验证实现' (verify implementation), '处理验证失败决策' (handle verification-failure decisions), '完成分支收尾' (complete branch wrap-up) — matching the 'lists multiple specific concrete actions' anchor; it is not the level below which only names a domain and a single action.

It explicitly answers both 'what' (verify implementation, handle failure decisions, finish branch) and 'when' via the explicit 'Use when Comet change 已完成 build 阶段...' trigger clause, satisfying the 'clearly answers both what AND when with explicit triggers' anchor; the 'Use when' clause is present so it is not capped at 2.

It includes relevant trigger keywords tied to workflow state ('已完成 build 阶段', '验证', '分支收尾') but these are workflow-internal jargon rather than the natural varied phrasings a user would commonly say, so it sits at 'some relevant keywords but missing common variations' rather than the full coverage of level 3.

The trigger is tightly scoped to 'Comet change' in a specific lifecycle state ('已完成 build 阶段'), giving it a clear niche unlikely to fire for unrelated skills; it is distinguishable rather than the 'somewhat specific but could overlap' level 2.
