Conciseness

Every line is an executable command or a terse instruction; no concepts Claude already knows are explained, so each token earns its place.

Actionability

Three copy-paste-ready, fully-qualified cargo commands with exact flags (e.g. `cargo clippy --locked --all-targets --all-features -- -D warnings`) plus a concrete fix action for step 1.

Workflow Clarity

A clearly sequenced numbered list with an explicit fix-and-retry loop on the formatting step; these are non-destructive checks, so the simple-skill allowance applies and the sequence is unambiguous.

Progressive Disclosure

Under 50 lines, single-purpose, with no need for external references; the well-organized numbered-list structure satisfies the simple-skill bar for progressive disclosure.

Specificity

"Run Rust fmt, clippy, and unit tests" lists three concrete, specific actions rather than vague language, matching the score-3 anchor of multiple specific concrete actions.

Completeness

It states what ("Run Rust fmt, clippy, and unit tests") and an explicit when clause ("Use after making Rust code changes"), clearly answering both halves.

Trigger Term Quality

Natural Rust terms users would say — "Rust fmt", "clippy", "unit tests", "Rust code changes" — give good coverage of the phrasing a developer uses when asking for local checks.

Distinctiveness Conflict Risk

Scoped to Rust-specific check tooling with a distinct trigger (post-code-change), making it unlikely to fire for unrelated skills.
