Conciseness

The body is dense and directive with no explanation of concepts Claude already knows, but contains minor redundancy: the git-staging rule and LSP re-verification instruction each appear twice (in the protocol and the CRITICAL section), and the example batching table is padding. This places it at efficient-with-minor-trimmables rather than the every-token-earns-its-place level 5.

Actionability

Guidance is fully executable: copy-paste-ready commands ("bunx tsc --noEmit --noUnusedLocals --noUnusedParameters", "bun run typecheck", specific git add/commit lines), a complete fill-in agent prompt template, and concrete example tables covering the common cases. Nothing remains pseudocode or abstract.

Workflow Clarity

Five phases are clearly sequenced with explicit validation checkpoints throughout: LSP verification before any removal, per-agent re-verification, typecheck gates with revert-on-failure feedback loops, a final typecheck/test/build pass, plus abort conditions and a zero-candidate stop. The destructive batch operations are fully wrapped in validation, so the workflow-clarity cap does not apply.

Progressive Disclosure

The skill is a single well-sectioned file with clear phase headers and no external references, and no bundle files exist. Structure is good, but at ~210 lines all content is inline — the sizable agent prompt template and batching example could live in a reference file — so it falls just short of the ideally-split level-5 anchor.

Specificity

"Remove unused code" is the only concrete action; "LSP-verified safety, atomic commits" are process attributes rather than distinct actions, and "ultrawork mode" is undefined jargon. This matches the anchor naming the domain with 1-2 concrete actions but not comprehensive coverage, rather than the level-4 anchor listing several specific actions.

Completeness

It explicitly answers both "what" ("Remove unused code... with LSP-verified safety, atomic commits") and "when" via the concrete trigger list ("Triggers: remove dead code, dead code, cleanup, remove unused"), matching the anchor requiring both with concrete trigger phrases.

Trigger Term Quality

"remove dead code, dead code, cleanup, remove unused" are phrases a user would naturally say, giving good keyword coverage. Common variations like "unused code", "unused imports/exports", and "dead code removal" are missing, keeping it below the comprehensive level-5 anchor.

Distinctiveness Conflict Risk

Dead-code removal is a clear niche with distinct triggers ("dead code", "remove unused"), but the generic trigger "cleanup" creates minor overlap risk with general cleanup/refactoring skills, so it sits at mostly-distinct rather than minimal-conflict.
