About skill-creator

A guide for creating reusable agent skills, with conventions for structure, naming, content, references, and registration. It is aimed at contributors building project-specific or general skills, especially within Prowler repositories.

Key features

  1. 01Skill creation criteria
  2. 02SKILL.md structure and fields
  3. 03Naming conventions
  4. 04Assets and references guidance
  5. 05Content and checklist guidance
  6. 06AGENTS.md registration

Use cases

  1. 01Creating a reusable project skill
  2. 02Choosing assets versus references
  3. 03Defining skill triggers and metadata
  4. 04Registering a skill for agents

Install

Copy the command and run it in a terminal.

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

## 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

Naming Conventions

TypePatternExamples
Generic skill{technology}pytest, playwright, typescript
Prowler-specificprowler-{component}prowler-api, prowler-ui, prowler-sdk-check
Testing skillprowler-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

FieldRequiredDescription
nameYesSkill identifier (lowercase, hyphens)
descriptionYesWhat + Trigger in one block
licenseYesAlways Apache-2.0 for Prowler
metadata.authorYesprowler-cloud
metadata.versionYesSemantic 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) |

Checklist Before Creating

  • Skill doesn't already exist (check skills/)
  • Pattern is reusable (not one-off)
  • 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

  • Templates: See assets/ for SKILL.md template
