Conciseness

The body is mostly efficient — tables, terse imperatives, no concept explanations Claude doesn't need — but the 'Rationalization Table' and 'Red Flags — STOP and Verify' sections repeat the same items ('I'm confident' and the subagent-excuse rows appear in both), which could be merged. Only one padded theme keeps it above anchor 2.

Actionability

Concrete, executable guidance throughout: the 5-step gate (IDENTIFY/RUN/READ/VERIFY/ONLY THEN), the claim-to-evidence table, real bash commands for the synthesis-file checks, and correct/incorrect output examples. The general-case verification command is necessarily project-specific and left implicit, a minor gap that keeps it below the copy-paste-ready bar of a 5.

Workflow Clarity

The Gate is a clearly sequenced 5-step procedure that is itself a validation sequence (READ full output, check exit code, count failures, VERIFY the output confirms the claim). The red-green regression example is an explicit feedback loop (revert fix → fail → restore), and the Evidence and When-to-Apply tables act as checklists.

Progressive Disclosure

A single-file skill (~130 lines) with clear, well-ordered section headers and no nested references — content is appropriately placed inline for its size. Minor gap: the host note and 'Integration with Other Skills' reference files (skills/blocks/codex-host-adapter.md, flow-develop.md, skill-tdd.md) that are not present in the bundle.

Specificity

The description names the trigger situation concretely ('declare work complete, fixed, passing, or done') but states no actions the skill performs — there is no verb describing what it does (verify, gate, run). It is not pure abstract language (ruling out 1), but it lists none of the skill's concrete actions (ruling out 3).

Completeness

Only a 'when' clause is present ('Use when about to declare work complete, fixed, passing, or done'); the 'what' — that the skill gates completion claims behind fresh verification evidence — is entirely absent and must be inferred. This matches anchor 2 ('only when is present without what') exactly; anchor 3 requires a clear 'what', and none is explicitly stated.

Trigger Term Quality

'complete, fixed, passing, or done' gives good natural coverage of completion-claim synonyms an assistant or user would actually say. Missing verification-adjacent terms like 'verify', 'tests pass', or 'before committing', so it falls short of the comprehensive synonym coverage of a 5.

Distinctiveness Conflict Risk

The trigger moment is somewhat specific, but 'about to declare work complete' fires at the end of nearly every task and overlaps with verification-type skills (e.g., a project's own verify/test skill). It could still collide with similar skills, matching anchor 3 rather than the minor-overlap profile of anchor 4.
