Conciseness

The body is lean (~55 lines): a Quick Reference table, tight forbidden/correct code pairs, and a short Related Skills list. It assumes Claude's competence and explains nothing the model already knows, so every token earns its place.

Actionability

The three rule sections give concrete, copy-adaptable forbidden/correct TypeScript pairs ('await apiCall();', 'string.toLowerCase()', 'const { x } = await CoreSDKLoader();'). It falls short of 5 because of '...' path placeholders in the imports and because date formatting and error handling have no inline example, deferring entirely to references.

Workflow Clarity

This is a rules-lookup skill rather than a multi-step workflow, and each rule is unambiguous via the forbidden/correct pairing, so the single action (apply these patterns) is clear. It is not a 5 because there is no guidance on when to consult which reference beyond the table, and no verification step for confirming compliance.

Progressive Disclosure

The Quick Reference table clearly signals five one-level-deep references under references/rules/, all of which exist and are appropriately split out of the overview. It is not a 5 because the bundle also contains unreferenced date-formatting.md and error-handling.md files at the references/ root that differ from the rules/ versions, which is a minor organization gap that could mislead navigation.

Specificity

The phrase 'OneKey coding patterns for TypeScript, React, promises, date formatting, and error handling' names the domain and enumerates five concrete topic areas, but describes topics with nouns rather than concrete actions (no verbs like 'enforce' or 'apply'). It sits between anchor 2 (domain named, actions generic) and anchor 3 (domain plus concrete actions), and the enumerated topics give it more information than the anchor-2 example.

Completeness

The 'what' is clear (OneKey coding patterns across five named areas), but there is no 'Use when...' clause or equivalent explicit trigger guidance, which caps completeness at 3 per the judging guidelines. It is not a 4 because 'when' is entirely absent rather than merely implicit.

Trigger Term Quality

'TypeScript', 'React', 'promises', 'date formatting', and 'error handling' are natural terms users would say, giving good keyword coverage. A few natural variations are missing (e.g. 'async/await', 'hooks', 'imports', 'linting'), so it does not reach comprehensive synonym coverage.

Distinctiveness Conflict Risk

The 'OneKey' prefix establishes a clear niche unlikely to trigger for unrelated skills, but 'coding patterns' covering broad topics like React and promises carries minor overlap risk with closely related code-quality or architecture skills.
