The skill is mostly efficient and well-structured with tables and templates, but includes some content Claude already knows (e.g., the Fixer API comments listing all methods, basic explanations of when not to autofix). The utility table and archetype table are valuable domain-specific knowledge. Some sections like 'Extending an Existing Rule' add breadth that could be a separate reference.

Provides fully executable TypeScript templates for both rule and test files, concrete bash commands for running tests, specific file paths for registration, and real utility names with their locations. The templates are copy-paste ready with clear placeholder variables ($ARGUMENTS, $RULE_NAME).

Clear 4-step sequence (Choose Archetype → Check Utilities → Create Files → Register Rule) with explicit verification steps (run tests after creation and after registration). The workflow includes a feedback loop via test execution and clear validation checkpoints before proceeding.

The skill provides a clear overview with well-signaled one-level-deep references to archetype docs, style-collector guide, and schema patterns. The main SKILL.md stays focused on the workflow while pointing to specific reference files for detailed archetype information. Tables make navigation easy.

Lists multiple specific concrete actions: rule creation, test authoring, registration, and autofix implementation. These are clear, actionable capabilities.

Clearly answers both 'what' (create ESLint rules with tests, covering rule creation, test authoring, registration, autofix) and 'when' (explicit 'Use when' clause with multiple trigger phrases).

Excellent coverage of natural trigger phrases users would say: 'create a lint rule', 'add an eslint rule', 'scaffold a rule', 'write a new scraps rule', 'new design system lint rule'. These are realistic user phrasings with good variation.

Highly distinctive — targets a specific plugin (eslintPluginScraps), a specific task (ESLint rule creation), and includes domain-specific terms like 'scraps rule' and 'design system lint rule' that clearly distinguish it from general coding or linting skills.
