## When to Create a Skill

Create a skill when:
- A pattern is used repeatedly and AI needs guidance
- Project-specific conventions differ from generic best practices
- Complex workflows need step-by-step instructions
- Decision trees help AI choose the right approach

**Don't create a skill when:**
- Documentation already exists (create a reference instead)
- Pattern is trivial or self-explanatory
- It's a one-off task

---

## Skill Structure

```
skills/{skill-name}/
├── SKILL.md              # Required - main skill file
├── assets/               # Optional - templates, schemas, examples
│   ├── template.py
│   └── schema.json
└── references/           # Optional - links to local docs
    └── docs.md           # Points to project documentation
```

## SKILL.md Template

```markdown
---
name: {skill-name}
description: >
  {One-line description of what this skill does}.
  Trigger: {When the AI should load this skill}.
license: MIT
metadata:
  author: edoriban
  version: "1.0"
  scope: [root]
  auto_invoke: "{Action that triggers this skill}"
---

## When to Use

{Bullet points of when to use this skill}

## Critical Patterns

{The most important rules - what AI MUST know}

## Code Examples

{Minimal, focused examples}

## Commands

```bash
{Common commands}
```

## Resources

- **Templates**: See [assets/](assets/) for {description}
- **Documentation**: See [references/](references/) for local docs
```

## Naming Conventions

| Type | Pattern | Examples |
|------|---------|----------|
| Generic skill | `{technology}` | `pytest`, `playwright`, `typescript` |
| Project-specific | `{project}-{component}` | `myapp-api`, `myapp-ui` |
| Testing skill | `{project}-test-{component}` | `myapp-test-sdk` |
| Workflow skill | `{action}-{target}` | `skill-creator`, `skill-sync` |

---

## Decision: assets/ vs references/

```
Need code templates?        -> assets/
Need JSON schemas?          -> assets/
Need example configs?       -> assets/
Link to existing docs?      -> references/
Link to external guides?    -> references/ (with local path)
```

---

## Frontmatter Fields

| Field | Required | Description |
|-------|----------|-------------|
| `name` | Yes | Skill identifier (lowercase, hyphens) |
| `description` | Yes | What + Trigger in one block |
| `license` | Yes | License type (e.g., `MIT`) |
| `metadata.author` | Yes | Your identifier (e.g., `edoriban`) |
| `metadata.version` | Yes | Semantic version as string |
| `metadata.scope` | Yes | Which AGENTS.md files to update |
| `metadata.auto_invoke` | Yes | Action that triggers this skill |

---

## Content Guidelines

### DO
- Start with the most critical patterns
- Use tables for decision trees
- Keep code examples minimal and focused
- Include Commands section with copy-paste commands

### DON'T
- Add Keywords section (agent searches frontmatter, not body)
- Duplicate content from existing docs (reference instead)
- Include lengthy explanations (link to docs)
- Add troubleshooting sections (keep focused)

---

## Registering the Skill

After creating the skill, run the sync command:

```bash
./bin/sync
```

This will automatically update AGENTS.md with your new skill.
