Conciseness

Lean bullet-driven body with no padding over concepts Claude already knows; the only trim opportunity is repeated inline pointers to the same reference files across sections, keeping it just below the fully lean anchor at 5.

Actionability

Concrete, specific remediation guidance ('Narrow state scope', 'Stabilize identities for ForEach', 'Downsample images before rendering') is actionable; as an instruction-only skill the absence of code is not penalized, but it stops short of copy-paste examples that would reach 5.

Workflow Clarity

A clearly numbered six-step sequence (Intake through Verify) with an explicit verification checkpoint and an escalation feedback loop when code review is inconclusive; not a 5 because error-recovery detail and checklists are lighter than the top anchor.

Progressive Disclosure

The body is an overview with well-signaled, one-level-deep references to real bundle files (code-smells.md, profiling-intake.md, report-template.md), with content appropriately split and a consolidated References list for easy navigation.

Specificity

Names the domain (SwiftUI runtime performance) and one concrete approach ('Audit ... from code first'), but does not list multiple specific actions, matching the '1-2 concrete actions, not comprehensive' anchor rather than the multi-action anchor at 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, matching the top anchor.

Trigger Term Quality

Natural user-facing phrases ('slow rendering', 'janky scrolling', 'expensive updates', 'profiling needs') give good keyword coverage, but it omits common synonyms and file/extension variants that would warrant a 5.

Distinctiveness Conflict Risk

Targets a clear niche (SwiftUI runtime performance) with distinct diagnostic triggers, giving minimal overlap risk with other skills.
