Conciseness

Largely lean and opinionated — a decision table, terse checklists, and no padding explaining basic concepts Claude already knows. Not a 5 because several sections run long for a single point (the 'Prefer Inline' section spends ~70 lines on TypeScript plus Svelte examples; the 'Collapsing Duplicate Branches' section shows two separate before/after pairs for one principle), and the opening 'Related Skills' paragraph is a dense wall of six cross-references.

Actionability

Consistently concrete: before/after TypeScript diffs, a caller-count decision table, a grep-driven straggler checklist, and labeled commit examples ('refactor: inline ValidatedEntry type...'). Not a 5 because a few examples are illustrative fragments rather than complete code — the asRichText snippet elides bodies with '/* push richtext from plaintext */' and the first collapse example's AFTER block opens with a dangling '} else {' — so they instruct rather than execute.

Workflow Clarity

A clear sequence runs audit (count callers) → decide (table) → present diff with tradeoffs → surgical commits ('edit → diagnostics → test → commit') → straggler sweep → Go-to-Definition check, with validation checkpoints between commits. Not a 5 because the entry point is implicit — the phases are presented as topic sections rather than an ordered procedure — and the 'Presenting Changes' validation (wait for reviewer approval) is stated but not looped back into the commit sequence.

Progressive Disclosure

The single ~380-line file is well-sectioned with headers, but everything lives inline — no bundle files exist, and content that would suit a reference (the straggler-sweep case study, the Go-to-Definition mechanics, the full worked examples) is not split out. Cross-skill pointers ('See post-implementation-review', 'See rethink', the ../asymmetric-wins/SKILL.md link) are signaled but point outside this bundle, so navigation to detail depends on skills not shipped here. This matches the score-3 anchor: structure present, but content that should be separate is inline.

Specificity

Names the domain ('behavior-preserving code simplifications') and three concrete techniques — 'inlining, branch collapse, and typed access boundaries' — comparable to the score-4 anchor's 'extracts text, fills forms, converts pages to images'. Not a 5 because coverage stops at three named actions and omits other capabilities the body teaches (straggler sweep, parameter objects, surgical commits).

Completeness

Explicitly answers both: what ('Apply caller-aware, behavior-preserving code simplifications such as inlining, branch collapse, and typed access boundaries') and when ('Use when cleaning up code or planning focused refactor commits'). This matches the score-5 anchor's what+when pattern with concrete trigger phrases.

Trigger Term Quality

Includes natural phrases users would actually say — 'cleaning up code', 'refactor', 'planning focused refactor commits' — plus technique keywords like 'inlining'. Not a 5 because common synonyms such as 'simplify', 'tidy', 'dead code', or 'deduplicate' are missing.

Distinctiveness Conflict Risk

Distinctive markers ('caller-aware', 'typed access boundaries', 'refactor commits') separate it from generic cleanup, review, or testing skills. Not a 5 because 'cleaning up code' overlaps with broader code-cleanup/linting skills, so a minor collision risk remains.
