Discovery
85%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 a solid skill description that clearly identifies its domain (Zig programming), lists specific capabilities (tagged unions, error sets, comptime validation, memory management), and includes an explicit trigger clause. Its main weakness is slightly limited trigger term coverage—it could mention file extensions like '.zig' and alternative phrasings users might use.
Suggestions
Add file extension '.zig' as a trigger term to catch users referencing files by extension
Include additional natural trigger terms like 'Zig code', 'Zig programming', or 'Zig project' to improve matching coverage
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions/concepts: tagged unions, explicit error sets, comptime validation, memory management, and type-first development patterns. These are concrete, well-defined Zig language features. | 3 / 3 |
Completeness | Clearly answers both 'what' (provides Zig patterns for type-first development with tagged unions, explicit error sets, comptime validation, and memory management) and 'when' ('Must use when reading or writing Zig files') with an explicit trigger clause. | 3 / 3 |
Trigger Term Quality | Includes 'Zig files' and 'Zig' as natural keywords, plus domain-specific terms like 'tagged unions', 'comptime', and 'error sets'. However, it misses common variations like '.zig', 'Zig code', 'Zig programming', or 'Zig project'. The technical terms are appropriate for the audience but coverage of natural user phrasing is limited. | 2 / 3 |
Distinctiveness Conflict Risk | Zig is a specific programming language with a clear niche. The description targets Zig files specifically, making it very unlikely to conflict with skills for other languages or general coding tasks. | 3 / 3 |

Implementation
72%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a solid, comprehensive Zig best practices skill with excellent actionability through numerous executable code examples and good progressive disclosure via linked advanced guides. Its main weaknesses are moderate redundancy across sections (duplicate examples for comptime validation and switch patterns) and a lack of explicit compile-validate-fix workflow steps that would help Claude catch errors when writing Zig code.
Suggestions
Remove duplicate examples: the comptime buffer validation and processStatus switch appear in multiple sections—consolidate them to reduce token usage.
Add an explicit compile-test workflow checkpoint, e.g., '1. Write code → 2. Run `zig build` → 3. Fix compiler errors → 4. Run `zig build test` → 5. Verify no leaks' to improve workflow clarity.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is generally efficient but has some redundancy—several patterns are shown twice (e.g., comptime buffer validation appears in both 'Type-First Development' and 'Comptime Patterns'; processStatus switch appears twice). Some instructional bullets restate what the code examples already demonstrate. The 'Avoiding anytype' section could be folded into the comptime section. However, it avoids explaining basic Zig concepts Claude would know. | 2 / 3 |
Actionability | Nearly every guideline is backed by executable, copy-paste-ready Zig code examples with good/bad comparisons. The code is concrete, uses real standard library APIs, and covers practical patterns like error handling, memory management, config loading, and testing with leak detection. | 3 / 3 |
Workflow Clarity | The type-first development workflow at the top provides a clear 4-step sequence, but lacks explicit validation checkpoints or feedback loops. The Instructions section is a flat bullet list without sequencing. For a skill that involves writing Zig files, there's no compile-test-fix loop or verification step mentioned. | 2 / 3 |
Progressive Disclosure | The skill has a clear structure with well-organized sections, and appropriately defers specialized topics (generics, C interop, debugging) to linked files. The 'Advanced Topics' section provides one-level-deep references with clear descriptions. External references to official docs are included at the end. | 3 / 3 |
Total | 10 / 12 Passed |
