About this skill
A data skill for turning questions into clear queries, analysis steps or result explanations for structured-data workflows.
Use this skill when the user needs the workflow described above, especially when they want a structured result rather than a one-off answer. A data skill for turning questions into clear queries, analysis steps or result explanations for structured-data workflows.
Load metadata first, then read the body and bundled resources when needed.
Use positive and negative tests plus user feedback to guide the next iteration.
Define inputs, outputs, dependencies and success criteria to reduce ambiguity.

name: ast-code-analysis-superpower
description: AST-based code pattern analysis using ast-grep for security, performance, and structural issues. Use when (1) reviewing code for security vulnerabilities, (2) analyzing React hook dependencies or performance patterns, (3) detecting structural anti-patterns across large codebases, (4) needing systematic pattern matching beyond manual inspection.

# AST-Grep Code Analysis
AST pattern matching identifies code issues through structural recognition rather than line-by-line reading. Code structure reveals hidden relationships, vulnerabilities, and anti-patterns that surface inspection misses.
## Configuration
- **Target Language**: ${language:javascript}
- **Analysis Focus**: ${analysis_focus:security}
- **Severity Level**: ${severity_level:ERROR}
- **Framework**: ${framework:React}
- **Max Nesting Depth**: ${max_nesting:3}
## Prerequisites
```bash
# Install ast-grep (if not available)
npm install -g @ast-grep/cli
# Or: mise instalnameAST Code Analysis SuperpowerdescriptionUse this skill when the user needs the workflow described above, especially when they want a structured result rather than a one-off answer.

- 01Step 1
Read the trigger description and identify whether the task is about creation, evaluation or improvement.
- 02Step 2
Open SKILL.md and confirm the input, output and bundled resource requirements.
- 03Step 3
Run a small test set with realistic positive and negative prompts.
- 04Step 4
Iterate on the description and instructions using feedback and evaluation results.
Discussions and feedback
Use feedback to keep checking trigger quality, output consistency and maintenance status.
