Conciseness

The prose is tight, declarative, and assumes Claude's competence — it never explains what a test suite or coverage tool is, and the Meszaros/Fowler quotes carry decision weight rather than padding (so not the score-3 anchor, which requires unnecessary explanation). It falls short of the lean-every-token anchor because the same rules are restated across sections: 'Never batched' appears in the Step 1 table, Step 2, Step 4, and the anti-patterns table, and the gate conditions recur in the burden-of-proof rules, never-remove list, Step 3, and anti-patterns — deliberate reinforcement that could be trimmed without losing any decision.

Actionability

Guidance is fully executable for an instruction-only skill: the 'normalized (describe-path, normalized-setup, normalized-assertion-arguments)' signature, the four gate conditions with 'A missing input is a failed condition, not a skipped one', the executable test.each fold example, the ledger/kept-table columns, and a seven-row worked example with file:line candidates covering every class. Every rule names exactly how to apply it, matching the fully-executable anchor.

Workflow Clarity

The five-step sequence is explicit and ordered, and for a destructive batch operation the validation is built in: the delete gate is a conjunctive checkpoint where 'any failed or missing-input condition reverts the verdict to keep', the kept table records 'the failing condition named' as the feedback record, and the never-remove list plus the three-question dead-signal checklist act as checklists. This matches the explicit-validation-with-feedback-loops anchor; the worked example's gate-failure rows demonstrate the recovery path.

Progressive Disclosure

The SKILL.md holds the decision core while both referenced files exist and correctly absorb the deeper material: 'the full method per class - normalized signatures, detection heuristics, code examples, the dead-signal thresholds and reviewer checklist' in references/applying-the-removal-classes.md, and 'templates and the confidence-to-action rules' in references/removal-ledger-and-report-format.md. References are one level deep, each link is signaled with a description of its contents, and the split (decision logic in SKILL, method and recording format in references) is appropriate — matching the clear-overview anchor.

Specificity

The description lists multiple concrete actions with named mechanics: 'Sorts candidates into duplicate, tautology, trivial, dead-signal and orphan, and deletes only when all four gate conditions hold, with a written reason, coverage evidence and a named reviewer.' Five named classes plus gate conditions and evidence requirements comprehensively cover the skill's capability, matching the comprehensive-coverage anchor rather than the minor-gaps anchor below it.

Completeness

Both questions are explicitly answered: the when is 'Use when a suite has outgrown its value and someone is about to delete tests', and the what is sorting into five named classes with a four-condition delete gate plus reason/evidence/reviewer requirements. The trigger 'someone is about to delete tests' is a concrete trigger phrase, matching the explicit-both anchor; the score-4 anchor ('when' could be more explicit) does not fit since the when clause names the exact triggering situation.

Trigger Term Quality

Natural trigger phrases are present — 'a suite has outgrown its value', 'someone is about to delete tests', 'suite' — capturing what a user would say at the trigger moment. A few common synonyms are missing (e.g. 'remove tests', 'prune', 'cleanup', 'redundant tests'), which fits the good-coverage-with-a-few-missing-terms anchor rather than the comprehensive-synonyms anchor.

Distinctiveness Conflict Risk

The description carves a clear niche — deleting tests from a suite — with distinct triggers ('delete tests', the five class names) and no plausible confusion with adjacent skills like test selection or flaky-test handling. Minimal conflict risk matches the clear-niche anchor; the score-4 anchor's 'minor overlap risk with closely related skills' is not evidenced.
