Conciseness

The body is lean and instructional with no explanation of concepts Claude already knows; the SHA commands, placeholder table, and worked example all earn their tokens. Minor trim opportunities exist: the Critical/Important fix rules and the rebut-with-technical-reasons guidance each appear twice (in 处理反馈 and again in 红线), and the rationalization table is partly motivational padding. This fits anchor 4 ('efficient; minor instances that could be trimmed'), not 5 (the duplication keeps it from being fully lean) and not 3 (there is no genuinely unnecessary explanation).

Actionability

Concrete, executable guidance throughout: exact shell commands for BASE_SHA/HEAD_SHA, a defined placeholder schema ({DESCRIPTION}, {PLAN_OR_REQUIREMENTS}, {BASE_SHA}, {HEAD_SHA}), explicit feedback triage rules, and a filled-in worked example. The gap keeping it from anchor 5 is that the core dispatch step depends entirely on the code-reviewer.md template, which is referenced but not present in the bundle, so the prompt cannot be copy-paste assembled from this skill alone.

Workflow Clarity

The three-step sequence (get SHAs → dispatch reviewer → triage feedback) is clearly numbered with executable commands, explicit checkpoints (Important issues must be fixed before continuing), and error-recovery handling for a mistaken reviewer. It falls short of anchor 5 because the loop is not closed: after fixing Critical/Important issues the skill proceeds directly to the next task (as the example shows) without a re-review checkpoint to confirm the fixes. No destructive/batch operation is involved, so the workflow cap does not apply.

Progressive Disclosure

A single well-organized file with clear sections (when / how / example / red lines) and one clearly signaled, one-level-deep reference ("参见模板：requesting-code-review/code-reviewer.md") — matching anchor 4 ('good structure; references mostly clear; minor organization gaps'). It does not reach 5 because the referenced template file does not exist in the bundle (no references/ directory), leaving the pointer dangling rather than resolving to actual content.

Specificity

The only action stated is the generic "验证工作成果是否符合要求" (verify work output meets requirements), which names a domain but offers no concrete actions — it never mentions dispatching a review subagent, reviewing a diff, or any mechanism. It fits anchor 2 ('names the domain but actions are minimal or generic'), not 3 (which requires 1-2 concrete actions) and not 1 (a domain and an action are present).

Completeness

The 'when' is explicit (after task completion, after major features, before merge), but the 'what' is vague — "验证工作成果是否符合要求" says nothing about what the skill actually does (dispatch a code-review subagent with BASE_SHA/HEAD_SHA over a diff). Anchor 4 requires a real 'what' alongside the 'when'; anchor 2 is ruled out because a 'when' clause is present, leaving 3.

Trigger Term Quality

Trigger phrases "完成任务" (task completion), "实现重要功能" (implementing features), and "合并前" (before merge) are semi-natural, but the most obvious user phrases — "代码审查", "review", "审查代码" — are entirely absent, so a user asking for a code review would not naturally trigger this skill. This matches anchor 3 ('some relevant keywords but missing common variations or synonyms'), not 4 (good coverage) and not 2 (more than two relevant keywords exist).

Distinctiveness Conflict Risk

The pre-merge/task-completion framing ties it to development workflows, but "验证工作成果是否符合要求" (verify work output meets requirements) could equally describe testing, QA, or validation skills, giving moderate overlap risk. It is more specific than anchor 2 ('helps with document files' level breadth) but less distinct than anchor 4, which would require naming the concrete review mechanism.
