Conciseness

The body is dense and operational — tables map subagents to agents/templates/outputs/logs, and it never explains concepts Claude already knows. Minor redundancy keeps it below anchor 5: the '回退默认保留代码' rule is restated in 前置条件, §5, and 可重入约定, and the round-increment rule appears twice (§3 and the 可重入约定 table).

Actionability

Guidance is concrete and executable within its orchestration context: explicit tables for subagent dispatch, verdict-aggregation decisions ('四份全 LGTM，且无 CRITICAL/HIGH finding → 跳过修复'), fix routing by affected file path, and the interface-contract attribution rules with a stated judgment standard. As an instruction-only skill, deferring the actual commands to the referenced template file is a deliberate split with only minor gaps, so it sits at anchor 4 rather than 5.

Workflow Clarity

The multi-step process is clearly sequenced (four parallel validations → aggregation decision → in-place fix → state update → rollback) with explicit validation checkpoints and a full feedback loop: fix is followed by re-running all four validations (round +1), capped at '同 attempt 内最多 3 个 round', with forced escalation to rollback re-entry when retries are exhausted. This matches the anchor-5 pattern of validate → fix → re-validate with explicit retry and escalation rules.

Progressive Disclosure

The body acts as an overview that defers command/report-template detail to one-level-deep references with precise section pointers (§2.6–§2.10) and a dedicated 参考资料 section — good structure per anchor 4. It is not anchor 5 because no bundle files exist in this skill directory (no references/, scripts/, or assets/); the referenced paths ('../references/subagent-prompt-template.md', 'agents/code-reviewer.md', 'skills/bk-security-redlines/') point outside the bundle and cannot be verified, and references appear both inline and in the closing list.

Specificity

The description lists several concrete actions — '四维度并行校验（架构 / 安全 / CodeReview / 测试覆盖）', '按受影响文件路径分派 backend-developer / frontend-developer', '日志写入独立 process-validate-*.log', '回退默认保留代码' — with broad coverage of the stage's capabilities. It falls short of anchor 5 because the framing is internal pipeline jargon ('迭代执行流水线校验阶段') rather than fully concrete capability statements.

Completeness

The 'what' is clear and detailed (four-dimension parallel validation plus in-place fix plus rollback semantics), but there is no 'Use when...' or equivalent explicit trigger guidance — the 'when' is only weakly implied by '迭代执行流水线校验阶段'. Per the judging guidelines, a missing explicit trigger clause caps completeness at 3.

Trigger Term Quality

Relevant domain keywords exist ('校验', '修复', '安全', '测试覆盖', 'CodeReview'), matching anchor 3's 'some relevant keywords', but natural trigger phrasing a user would say is absent and the description leans on internal jargon like 'subagent', 'LGTM', and '迭代执行流水线'. Not anchor 2, since it does name the validation domain and its four dimensions rather than being purely generic.

Distinctiveness Conflict Risk

The description occupies a clear niche — the validate stage of a specific pipeline, with named subagents, log file patterns, and template section pointers — making it mostly distinct with minor overlap risk with sibling pipeline stages (implement/plan). It is not anchor 5 because its triggers are not distinct natural phrases but internal stage terminology.
