structural-search
Search code by AST structure using ast-grep. Find semantic patterns like function calls, imports, class definitions instead of text patterns. Triggers on: find all calls to X, search for pattern, refactor usages, find where function is used, structural search, ast-grep, sg.

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 a strong skill description that clearly communicates what the skill does (AST-based structural code search), how it differs from alternatives (semantic patterns vs text patterns), and when to use it (with a comprehensive 'Triggers on' clause). The description is concise, uses third person voice, and includes both tool-specific terms (ast-grep, sg) and natural language triggers.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'Search code by AST structure', 'Find semantic patterns like function calls, imports, class definitions'. Clearly distinguishes from text-based search by specifying structural/semantic pattern matching. | 3 / 3 |
Completeness | Clearly answers both 'what' (search code by AST structure, find semantic patterns like function calls, imports, class definitions) and 'when' (explicit 'Triggers on:' clause with multiple natural trigger phrases). | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural trigger terms: 'find all calls to X', 'search for pattern', 'refactor usages', 'find where function is used', 'structural search', 'ast-grep', 'sg'. These are phrases users would naturally say when needing this capability. | 3 / 3 |
Distinctiveness Conflict Risk | Clearly distinguishes itself from generic code search or text-based grep by emphasizing AST/structural search, semantic patterns, and the specific tool ast-grep/sg. The distinction from text patterns is explicitly stated, reducing conflict with regular search skills. | 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 excellent skill that is concise, highly actionable, and well-structured. It provides immediately executable ast-grep commands covering the most common use cases, with a clean quick reference table and well-organized references to deeper content. The only minor note is the slightly truncated content in the pattern syntax table (appears cut off), but the essential patterns section more than compensates.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient, using tables and code examples without unnecessary explanation. It doesn't explain what ASTs are or how ast-grep works internally—it just shows the patterns and commands. | 3 / 3 |
Actionability | Every example is a copy-paste ready command with concrete patterns. The 10 essential patterns cover real-world use cases with executable `sg` commands, and the quick reference table provides immediately usable command variations. | 3 / 3 |
Workflow Clarity | For this single-purpose search tool, the workflow is unambiguous: find patterns, optionally preview replacements, then apply. The distinction between preview (`-r`) and apply (`--rewrite`) serves as an implicit validation checkpoint for the refactoring use case. | 3 / 3 |
Progressive Disclosure | The skill provides a concise overview with essential patterns inline, then clearly signals one-level-deep references to language-specific patterns, security patterns, and advanced usage in the Additional Resources section. | 3 / 3 |
Total | 12 / 12 Passed |
