Generate, review, or refactor Swift code using modern language features from Swift 6.0 through 6.2.3. Use when writing new Swift code, reviewing existing code for outdated patterns, migrating from Swift 5.x to 6.x, debugging concurrency warnings, or answering questions about current Swift idioms. Covers concurrency, typed throws, noncopyable types, observation, testing, and more.

Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is an excellent skill description that hits all the marks. It provides specific actions, comprehensive trigger terms including version numbers, an explicit 'Use when...' clause with multiple scenarios, and clear distinctiveness through Swift version specificity. The description is concise yet thorough, covering both capabilities and use cases effectively.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'Generate, review, or refactor Swift code' and covers specific technical areas like 'concurrency, typed throws, noncopyable types, observation, testing.' Uses third person voice correctly. | 3 / 3 |
Completeness | Clearly answers both what ('Generate, review, or refactor Swift code using modern language features') AND when with explicit 'Use when...' clause covering five specific trigger scenarios: writing new code, reviewing, migrating, debugging, and answering questions. | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural terms users would say: 'Swift code', 'Swift 6.0', 'Swift 5.x to 6.x', 'concurrency warnings', 'Swift idioms', 'refactor', 'review', 'debugging'. Includes version numbers users would naturally reference. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with clear niche: Swift 6.x specifically, with version ranges (6.0-6.2.3) and migration from 5.x. Unlikely to conflict with generic coding skills or other language-specific skills due to explicit Swift version targeting. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
100%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is an exemplary skill file that demonstrates mastery of all evaluation dimensions. It provides comprehensive Swift 6.x guidance in a highly structured, token-efficient format with clear workflows, actionable checklists, and appropriate progressive disclosure to reference files. The SE-proposal traceability and version tagging add significant value for practical use.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Extremely lean and efficient. No unnecessary explanations of what Swift is or how programming works. Every section delivers actionable information with SE proposal citations. The quick reference table is particularly token-efficient. | 3 / 3 |
Actionability | Highly actionable with specific patterns, exact compiler flags, SE proposal numbers, and clear old→new mappings. The workflow decision tree provides concrete guidance for each use case, and the review checklist is immediately usable. | 3 / 3 |
Workflow Clarity | Excellent workflow structure with a decision tree covering 5 distinct scenarios (generate, review, migrate, debug, answer questions). The review checklist provides explicit validation checkpoints. Debug section maps specific error messages to solutions. | 3 / 3 |
Progressive Disclosure | Perfect progressive disclosure with clear overview in SKILL.md and well-signaled one-level-deep references to version-specific files (SWIFT_6_0.md, SWIFT_6_1.md, etc.) and MIGRATION.md. Navigation is explicit and organized by purpose. | 3 / 3 |
Total | 12 / 12 Passed |
