Conciseness

The body is lean and telegraphic ("Investigate aggressively; delete only with evidence"), assumes Claude's competence, explains nothing the model already knows, and every sentence carries an instruction. No over-explanation exists to trim, so it fits the top anchor rather than the 4 anchor.

Actionability

The decision gate's four concrete questions and per-step directives ("move unique assertions first, then retire duplicates and unused support") give specific, executable guidance for an instruction-only skill, but the body contains no commands or worked examples — those are delegated to the reference files, leaving minor gaps. Not 3 because the guidance is concrete rather than pseudocode-level hints.

Workflow Clarity

A clearly sequenced six-step workflow (Inspect, Plan, Prove, Edit, Validate, Review) with explicit validation checkpoints at steps 3, 5, and 6, error-recovery direction ("Diagnose failures before treating them as cleanup candidates"), and the decision-gate checklist. Validation is present for this destructive operation, so the destructive-cap does not apply, and the checkpoints are explicit rather than mostly present.

Progressive Disclosure

The overview routes by scope to three real, clearly signaled, one-level-deep references (audit.md, validation.md, paperclip.md) with nothing inlined that belongs elsewhere. However, the body references NOTICE.md and CAMPAIGN.md and paperclip.md points at ../CAMPAIGN.md, yet neither file exists in the bundle — broken navigation paths that keep this below the top anchor.

Specificity

Names several concrete actions — "finding and removing redundant, vacuous, or implementation-coupled tests" and "preserving useful regression coverage" — but omits repair/consolidation/validation activities from the body and "coordinated audit campaigns" is abstract, leaving minor coverage gaps.

Completeness

Explicitly answers both: the what is "finding and removing redundant, vacuous, or implementation-coupled tests while preserving useful regression coverage" and the when is an explicit "Use for" clause with concrete trigger phrases. Not 4 because the when-clause is explicit and specific rather than merely present with room for improvement.

Trigger Term Quality

"Use for test audits, test pruning, duplicate coverage, or reducing CI test cost" provides four natural trigger phrases a user would actually say, though common variations like "test cleanup" or "remove redundant/duplicate tests" are missing.

Distinctiveness Conflict Risk

Test-suite pruning/auditing is a clear niche with distinct triggers (test audits, pruning, duplicate coverage, CI test cost) that would not naturally fire a test-writing or general code-review skill. No meaningful overlap risk with closely related skills.
