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

A highly actionable, well-sequenced procedural skill with complete code templates, explicit testing guidance, and a verification checklist. It is efficient and clearly structured, with only minor conciseness and structure-splitting room for improvement.

Suggestions

Tighten explanatory prose around the testing approaches (e.g., the 'This is faster and avoids I/O dependencies' sentence) to push conciseness toward a 5.

Consider moving the extended test-code templates and documentation-format details into a referenced file to demonstrate a clearer overview-to-detail progressive-disclosure structure.

Dimension	Reasoning	Score
Conciseness	Mostly lean code-first guidance that assumes Dart competence, with only minor over-explanatory prose such as 'This is faster and avoids I/O dependencies' that could be trimmed.	4 / 5
Actionability	Provides copy-paste-ready Dart scaffolding for the rule class, registry registration, two test approaches, and documentation updates, covering the common cases concretely.	5 / 5
Workflow Clarity	A clearly numbered step sequence (create rule, register, handle defaults) is followed by explicit validation via a testing section and a PR checklist with verification commands (dart format, dart analyze --fatal-infos, dart test).	5 / 5
Progressive Disclosure	Well-organized into clearly headed sections (implementation, testing, documentation, checklist) with no nested references, though all content is inline and the overview-to-detail split pattern is not exercised.	4 / 5

Description

87%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.

A concise, well-targeted description that clearly states both the capability and the trigger condition for a narrow internal tooling task. It is specific and distinctive, with only minor room for broader trigger-term coverage.

Dimension	Reasoning	Score
Specificity	Names the domain and several concrete actions — 'adding a new validation rule and CLI flag to dart_skills_lint' and 'create a new rule that validates aspects of skills (like frontmatter metadata)' — with only minor coverage gaps.	4 / 5
Completeness	Explicitly answers both what ('Instructions for adding a new validation rule and CLI flag to dart_skills_lint') and when ('Use this skill when asked to create a new rule that validates aspects of skills') with a concrete trigger phrase.	5 / 5
Trigger Term Quality	Includes natural trigger phrases users would say ('validation rule', 'CLI flag', 'create a new rule', 'frontmatter metadata') with good coverage, though it lacks synonyms or file extensions that would push it to 5.	4 / 5
Distinctiveness Conflict Risk	Targets a clear, narrow niche (extending the dart_skills_lint package with a new rule and flag) with distinct triggers and minimal overlap risk with other skills.	5 / 5
	Total	18 / 20 Passed
