Conciseness

The body is ~26 lines of pure signal: a prerequisite pointer, a four-row command table, and a four-item list of what lint covers. No padding, no explanation of concepts Claude already knows; every token earns its place.

Actionability

Four copy-paste-ready commands ('./frb_internal lint --fix', './frb_internal lint', './frb_internal lint-dart', './frb_internal lint-rust') cover the common cases including the recommended default and per-language variants, with a concrete enumeration of the underlying checks.

Workflow Clarity

As a simple single-purpose skill the command choice is unambiguous, but the recommended '--fix' path rewrites files across the repo with no guidance on reviewing the auto-applied changes or what to do when lint failures remain. Clear sequence, minor validation gap — fits 'clear sequence with most checkpoints' rather than the explicit-validation anchor.

Progressive Disclosure

Under 50 lines with no need for external references, and the two sections ('Quick Reference', 'What Lint Includes') are well-organized. The 'frb-dev-env' mention is a clearly signaled sibling-skill prerequisite, not a buried or nested bundle reference.

Specificity

Names the domain ('flutter_rust_bridge') and concrete actions ('run lint, format, or clippy checks'), but coverage is not comprehensive — no mention of the Dart vs Rust scope, dart analyze, cargo fmt, or auto-fix capability that the body demonstrates. Fits the 'names domain and concrete actions, not comprehensive' anchor rather than the 'several specific actions, minor gaps' level above.

Completeness

Both parts are present: an explicit 'Use when you need to run lint, format, or clippy checks' trigger plus a clear (if embedded) statement of what the skill does. Not 5 because the 'when' is nearly circular with the 'what' and offers no distinct concrete trigger scenarios; not 3 because both what and an explicit when-clause exist.

Trigger Term Quality

'lint', 'format', 'clippy', and 'flutter_rust_bridge' are natural terms a user of this repo would actually say. A few common variations are missing ('fmt', 'style checks', 'analyzer', 'dart analyze'), keeping it just below the comprehensive-synonyms anchor.

Distinctiveness Conflict Risk

Scoping to 'flutter_rust_bridge' with 'clippy' gives it a clear niche, but generic 'lint' and 'format' terms create minor overlap risk with general Rust or Dart linting skills.
