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

## 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/

```text
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 | `prowler-cloud` | | `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`:

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