## About

## When to use this skill

Use this skill to see a complete example of a skill that keeps core instructions in `SKILL.md` and loads additional context only when needed.

## Core workflow

1. Read this file to understand the minimal, always-loaded guidance.
2. If you need detailed rules or a checklist, read `references/REFERENCE.md`.
3. If you need a template for output formatting, open `assets/skill-template.md`.
4. If you need to validate a skill folder, run `scripts/validate-skill.sh`.

## Output expectations

- The skill uses progressive disclosure correctly.
- Optional folders are used only when their content is needed.
- References are relative to the skill root and one level deep.
