Conciseness

The body is efficient and assumes competence — bullet lists of intake items, smell categories, and fixes with no basic-concept padding. Minor trimmable redundancy remains: the 'Workflow' list restates sections 1-6, and the same references are cited inline and again in the References section.

Actionability

Guidance is concrete and specific for an instruction-only skill (exact intake items, named smell categories like 'Unstable identity in lists and ForEach', specific fixes like 'Downsample images before rendering'), so the absence of code is not penalized. It is not fully copy-paste executable — no Swift snippets for fixes like equatable() or narrowed observation — which keeps it below the anchor-5 level.

Workflow Clarity

A clearly sequenced 6-step process with a conditional branch (profile only when code review is inconclusive) and an explicit verify step: 're-run the same capture and compare with baseline metrics'. The read-only diagnostic nature means the destructive-operation cap does not apply, and the verify step provides the feedback loop the anchor-5 example requires.

Progressive Disclosure

The body is a concise overview with well-signaled, one-level-deep references — all seven files cited (code-smells.md, profiling-intake.md, report-template.md, and four WWDC/doc references) exist in references/, and each section tells the reader exactly which file to open for detail. No nesting, no orphaned or missing paths.

Specificity

Names the domain ('SwiftUI runtime performance') and one concrete action ('Audit ... from code first'), matching the anchor for 1-2 concrete actions but not comprehensive coverage. It does not list several specific actions (e.g., profiling, remediation, verification) that would justify a 4.

Completeness

Explicitly answers both what ('Audit SwiftUI runtime performance from code first') and when ('Use when diagnosing slow rendering, janky scrolling, expensive updates, or profiling needs') with concrete trigger phrases. The 'when' clause is explicit and symptom-specific, so it exceeds the anchor-4 'could be more explicit' level.

Trigger Term Quality

Good natural keyword coverage — 'slow rendering', 'janky scrolling', 'expensive updates', 'profiling', 'performance' — but a few common user phrasings are missing (e.g., 'frame drops', 'hangs', 'laggy', 'Instruments'). Comprehensive synonym coverage of the anchor-5 example is not present.

Distinctiveness Conflict Risk

'SwiftUI runtime performance' is a clear niche with distinct triggers (rendering, scrolling, updates), unlikely to fire for general code-review or document skills. It sits at the anchor-5 example's level of niche specificity.
