Conciseness

The body is dense and operational with no padding that explains concepts Claude already knows, but it is noticeably repetitive: "If a code block below conflicts with this section, this section wins" appears three times (lines 21, 23, 25), the safest-to-riskiest order rule is stated twice (lines 190 and 222), and the WORKING/BLOCKED mailbox protocol is duplicated (lines 29 and 241). It fits anchor 3 (mostly efficient but could be tightened) rather than 2 because there is no concept-explaining fluff, and rather than 4 because the redundancy exceeds minor instances.

Actionability

Guidance is fully executable and copy-paste ready: exact scope command `git diff $(git merge-base main HEAD)..HEAD --name-only`, the `awk` pure-LOC measure, `bun run <programming skill dir>/scripts/typescript/check-test-junk.ts`, a complete `mutation-proof.ts` invocation with flags, a verbatim per-file `task(...)` prompt template, and a full output report format. This matches the 5 anchor with no gaps.

Workflow Clarity

Phases 0-6 are clearly sequenced with explicit validation throughout: behavior locked by green regression tests before any cut (Phase 2), a five-gate quality table, safety/behavior/quality checklists, and a fix-revert-revalidate feedback loop ("Repeat until all gates green AND checklist clean") with escalation after three failures. For a destructive/batch skill this matches the 5 anchor's explicit checkpoints and error-recovery loops.

Progressive Disclosure

No bundle files exist (no references/, scripts/, or assets/), so all ~367 lines live inline in SKILL.md: the ten-category catalog with KEEP/REFACTOR rules, the harness-compatibility tables, and the report template are all inlined rather than split into referenced files. Section headers are clear, matching anchor 3's "some structure but could be better organized", but not 4 since substantial reference material that should be separate is inline and the only file paths referenced belong to a different skill (programming/references/testing/...).

Specificity

The description lists multiple concrete actions — "Removes AI-generated code smells from branch changes or an explicit file list", junk-test classes "(prose pins, source greps, copied inventories, mock echoes)" each "proven by its class's rule before a cut" — giving comprehensive, specific coverage of what the skill does. It fits the 5 anchor rather than 4 because there are no notable gaps in the action coverage.

Completeness

Both questions are answered explicitly: the first sentence gives a concrete "what" (smell and junk-test removal behind regression tests with per-class proofs), and the second gives an explicit "when" with concrete trigger phrases. This matches the 5 anchor exactly; a 4 would require the when-clause to be less explicit.

Trigger Term Quality

"Use when the user asks to clean up, deslop, remove AI-slop patterns, or prune tests from recent changes" covers the natural phrasings a user would say, including synonyms (clean up / deslop / remove AI-slop / prune tests). Not 4: common variations are already covered, matching the comprehensive-coverage anchor.

Distinctiveness Conflict Risk

"deslop", "AI-slop patterns", and "prune tests from recent changes" define a clear niche with distinct triggers and minimal conflict risk. "clean up" is slightly generic but is scoped by "from recent changes", so this sits at the 5 anchor rather than the 4 anchor's "minor overlap risk".
