Use when adding or testing flutter_rust_bridge feature flags, especially flags that require coverage for both enabled and disabled states or should have package-level config plus item-level #[frb(...)] overrides.

92%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is a tight, well-structured instruction-only skill that gives concrete file paths and mechanism guidance with no wasted tokens. Its only gap is the absence of executable code examples, which is acceptable for an instruction-only skill but keeps actionability just below the top anchor.

Dimension	Reasoning	Score
Conciseness	Lean and efficient with no padding or re-explanation of concepts Claude already knows — every line is direct guidance, matching the 'lean and efficient; every token earns its place' anchor.	5 / 5
Actionability	Concrete, actionable guidance naming specific artifacts ('flutter_rust_bridge.yaml', the CLI, 'frb_example/pure_dart', item-level '#[frb(...)]' overrides); as an instruction-only skill it is mostly executable with only minor gaps, fitting the 4 anchor below the fully copy-paste-ready 5.	4 / 5
Workflow Clarity	A simple, single-purpose skill under 50 lines with clearly sequenced API-surface and test-coverage guidance and no destructive/batch operations requiring validation, so the simple-skill exception applies and clarity is unambiguous.	5 / 5
Progressive Disclosure	Well under 50 lines with no need for external references (none of references/scripts/assets are present) and cleanly organized sections, satisfying the guideline that simple skills can score 5 with well-organized sections alone.	5 / 5

Description

78%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is specific, well-triggered, and clearly distinct, explicitly pairing a 'Use when' clause with concrete capability statements about both-state coverage and config/override handling. The only shortfall is that trigger keyword coverage is strong rather than exhaustive.

Suggestions

Add a couple of natural synonyms (e.g. 'toggling', 'enabling/disabling flags') to push trigger_term_quality toward exhaustive coverage.

Tighten the 'what' clause into a crisp capability list first, then the 'Use when' trigger, to mirror the top completeness anchor.

Dimension	Reasoning	Score
Specificity	Names the domain and several concrete actions — 'adding or testing flutter_rust_bridge feature flags', 'coverage for both enabled and disabled states', 'package-level config plus item-level #[frb(...)] overrides' — with only minor gaps in full flag-operation coverage, fitting the 'several specific actions; minor gaps' anchor rather than the comprehensive 5 or the 1-2-actions 3.	4 / 5
Completeness	Explicit 'Use when...' trigger plus a clear 'what' (feature flags needing both-state coverage and config/override handling) — both present with the 'when' concrete but slightly elaborated rather than maximally explicit, fitting the 4 anchor above the 3 (which lacks 'when').	4 / 5
Trigger Term Quality	Good natural coverage with 'adding or testing ... feature flags', 'coverage', and 'enabled and disabled states', plus the domain name 'flutter_rust_bridge'; it lacks only a few synonyms, matching the 'good keyword coverage; a few natural terms missing' anchor and not the near-complete 5.	4 / 5
Distinctiveness Conflict Risk	A tightly scoped niche — flutter_rust_bridge feature flags with both-state coverage and #[frb(...)] override handling — gives clear distinct triggers and minimal conflict risk, matching the 'clear niche with distinct triggers' anchor.	5 / 5
