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

## 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}

• Templates: See assets/ for {description}
• Documentation: See references/ for local docs

## Naming Conventions

| Type | Pattern | Examples |
|------|---------|----------|
| Generic skill | `{technology}` | `pytest`, `playwright`, `typescript` |
| Prowler-specific | `prowler-{component}` | `prowler-api`, `prowler-ui`, `prowler-sdk-check` |
| Testing skill | `prowler-test-{component}` | `prowler-test-sdk`, `prowler-test-api` |
| Workflow skill | `{action}-{target}` | `skill-creator`, `jira-task` |

---

## 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)

**Key Rule**: `references/` should point to LOCAL files (`docs/developer-guide/*.mdx`), not web URLs.

---

## Decision: Prowler-Specific vs Generic

Patterns apply to ANY project? → Generic skill (e.g., pytest, typescript) Patterns are Prowler-specific? → prowler-{name} skill Generic skill needs Prowler info? → Add references/ pointing to Prowler docs

---

## Frontmatter Fields

| Field | Required | Description |
|-------|----------|-------------|
| `name` | Yes | Skill identifier (lowercase, hyphens) |
| `description` | Yes | What + Trigger in one block |
| `license` | Yes | Always `Apache-2.0` for Prowler |
| `metadata.author` | Yes | `gentleman-programming` |
| `metadata.version` | Yes | Semantic version as string |

---

## 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)
- Use web URLs in references (use local paths)

---

## Registering the Skill

After creating the skill, add it to `AGENTS.md`:

```markdown
| `{skill-name}` | {Description} | [SKILL.md](skills/{skill-name}/SKILL.md) |

• Name follows conventions
• Frontmatter is complete (description includes trigger keywords)
• Critical patterns are clear
• Code examples are minimal
• Commands section exists
• Added to AGENTS.md
