## What it does

The skill covers code generation techniques: template engines, AST manipulation, scaffolding and automated boilerplate. Inside you get a short guide plus reference files in the `references/` directory — template engines, AST-based generation, project scaffolding, OpenAPI client generation, database model generation, GraphQL code generation and the Plop.js generator.

The quick start shows a Handlebars component template: a props interface, the component itself, and the `pascalCase` and `kebabCase` helpers. From there the skill advises keeping templates configurable, versioning them, including tests and docs in generated code, and validating inputs before generation. A separate list covers what to avoid: hardcoded values in templates, mixing business logic into templates, building generators for one-off cases.

The skill installs through `npx skills add` and runs in Claude, Codex, Cursor, GitHub Copilot, Gemini CLI and OpenCode. It is a set of instructions, not a ready-made generator — you still build the working CLI yourself from the references. If your project already has a code generator, this skill will overlap with it, so it is worth checking whether extending the existing one is simpler.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill code-generation-template -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/code-generation-template/SKILL.md

## When to use it
- scaffold a new project or component
- generate repetitive boilerplate code
- create CRUD operations automatically
- build an API client from an OpenAPI spec
- generate TypeScript types from JSON Schema

## Example prompts
- generate a React component from `templates/component.hbs` with name and type props
- scaffold a new TypeScript project
- generate an API client from an OpenAPI spec

## Overview

Comprehensive guide to code generation techniques including template engines, AST manipulation, code scaffolding, and automated boilerplate generation for increased productivity and consistency.

## When to Use

- Scaffolding new projects or components
- Generating repetitive boilerplate code
- Creating CRUD operations automatically
- Generating API clients from OpenAPI specs
- Building code from templates
- Creating database models from schemas
- Generating TypeScript types from JSON Schema
- Building custom CLI generators

## Quick Start

Minimal working example:

```typescript
// templates/component.hbs
import React from 'react';

export interface {{pascalCase name}}Props {
  {{#each props}}
  {{this.name}}{{#if this.optional}}?{{/if}}: {{this.type}};
  {{/each}}
}

export const {{pascalCase name}}: React.FC<{{pascalCase name}}Props> = ({
  {{#each props}}{{this.name}},{{/each}}
}) => {
  return (
    <div className="{{kebabCase name}}">
      {/* Component implementation */}
    </div>
  );
};
```
