## What it does

The skill provides reference setups and templates for analyzing source code without executing it. It covers ESLint for JavaScript and TypeScript, Python type checking with pylint and mypy, SonarQube integration, and custom AST analysis.

It also details pipeline automation with pre-commit hooks and CI/CD checks. Overly strict rules from day one hurt productivity, so the skill recommends enabling rules incrementally. Custom lint rules should always have clear documentation for the team.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill static-code-analysis -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/static-code-analysis/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/static-code-analysis/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill static-code-analysis -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/static-code-analysis/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill static-code-analysis -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/static-code-analysis/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aj-geddes/useful-ai-prompts static-code-analysis
```

2. **Manually: put the files in place**
- File: `.github/skills/static-code-analysis/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill static-code-analysis -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aj-geddes/useful-ai-prompts --path skills/static-code-analysis
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/static-code-analysis/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill static-code-analysis -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/aj-geddes/useful-ai-prompts/tree/HEAD/skills/static-code-analysis/SKILL.md

## When to use it
- set up ESLint rules to block dangerous patterns like `eval` and object injection
- configure Python static analysis with pylint and strict mypy type checking
- prevent committing broken syntax or style issues using pre-commit hooks
- integrate automated vulnerability scanning into CI/CD pipelines
- build custom AST analysis scripts to check project-specific architecture rules

## Example prompts
- "Generate an `.eslintrc.js` config with TypeScript and security plugins following the skill"
- "Set up mypy and pylint configuration files for a Python project"
- "Create a pre-commit config to run linters automatically before git commit"

## Overview

Use automated tools to analyze code without executing it, catching bugs, security issues, and style violations early.

## When to Use

- Enforcing coding standards
- Security vulnerability detection
- Bug prevention
- Code review automation
- CI/CD pipelines
- Pre-commit hooks
- Refactoring assistance

## Quick Start

Minimal working example:

```javascript
// .eslintrc.js
module.exports = {
  extends: [
    "eslint:recommended",
    "plugin:@typescript-eslint/recommended",
    "plugin:security/recommended",
  ],
  plugins: ["@typescript-eslint", "security", "import"],
  rules: {
    "no-console": ["warn", { allow: ["error", "warn"] }],
    "no-unused-vars": "error",
    "prefer-const": "error",
    eqeqeq: ["error", "always"],
    "no-eval": "error",
    "security/detect-object-injection": "warn",
    "security/detect-non-literal-regexp": "warn",
    "@typescript-eslint/no-explicit-any": "warn",
    "@typescript-eslint/explicit-function-return-type": "error",
    "import/order": [
      "error",
      {
        groups: [
          "builtin",
          "external",
          "internal",
// ... (see reference guides for full implementation)
```

## Best Practices

### ✅ DO

- Run linters in CI/CD
- Use pre-commit hooks
- Configure IDE integration
- Fix issues incrementally
- Document custom rules
- Share configuration across team
- Automate security scanning

### ❌ DON'T

- Ignore all warnings
- Skip linter setup
- Commit lint violations
- Use overly strict rules initially
- Skip security scans
- Disable rules without reason
