Conciseness

The body is efficient and largely assumes Claude's competence, presenting a spine, manifestations, a procedure, templates, a ladder, and a worked example without explaining known concepts. A few philosophical guardrail sentences ("This is not arithmetic and not a quota", "The rule is evidence-seeking, not dramatic") could be trimmed, keeping it just below the lean/5 anchor.

Actionability

For a decision skill it gives concrete, fill-in-ready guidance: a 6-step procedure, a decision template, a UI refactor template, a 5-rung artifact ladder with when-to-use conditions, and a fully worked social sign-in example with specific deletion-prize entries. The guidance is specific and covers the common case.

Workflow Clarity

The Procedure is a clear numbered sequence with an explicit decision gate (steps 5-6) and a keep-when-load-bearing checkpoint, so validation is present rather than absent. It is a 4 rather than 5 because hard pre/post-execution verification is delegated to companion skills (refactoring counts callers; greenfield executes the break) rather than contained as an explicit validate-fix-retry loop here.

Progressive Disclosure

The file is well-organized with clear section headers and one clearly-signaled, one-level-deep external reference (the narrative article path at the end), with no nested references. It is a 4 rather than 5 because everything lives in a single ~200-line file with no bundle splitting; the worked example or detailed templates could arguably move into reference files.

Specificity

It names the domain and one or two concrete actions ("refusing a small promise", "eliminate disproportionate complexity") but describes essentially a single refusal move rather than a comprehensive list of distinct actions. It sits above the minimal/generic anchor (2) yet below the several-specific-actions anchor (4).

Completeness

It explicitly answers both: the "what" ("Identify an asymmetric win by refusing a small promise that would eliminate disproportionate complexity") and the "when" ("Use when the user asks about..."), with concrete trigger phrases. This matches the anchor that requires both with explicit triggers.

Trigger Term Quality

The "Use when..." clause lists several natural trigger phrases users would say — "asymmetric wins", "pixel perfect fidelity", "compatibility", "fallbacks", "modes", "duplicate paths" — giving good keyword coverage. It is not a 5 because synonym coverage is limited and no file-extension-style terms apply to this concept.

Distinctiveness Conflict Risk

The core concept "asymmetric wins" is a distinct niche, but several triggers ("compatibility", "fallbacks", "modes") are broad and overlap with closely related refactoring/cleanup skills the body itself composes with. It is mostly distinct with minor overlap risk, below the minimal-conflict anchor (5).
