Usage:
  create-skill.sh <skill-name> [--minimal|--full] [--output <dir>] [--force]

Notes:
  - <skill-name> MUST be lowercase, start with a letter, and only contain letters, digits, and hyphens
  - Default mode: --full
  - Default output: current directory (creates ./<skill-name>/)

Examples:
  ./skills/claude-skills/scripts/create-skill.sh postgresql --full --output skills
  ./skills/claude-skills/scripts/create-skill.sh my-api --minimal

## Quick Links

- Getting started: \`getting_started.md\`
- API/CLI/config: \`api.md\` (if applicable)
- Examples: \`examples.md\`
- Troubleshooting: \`troubleshooting.md\`

## Notes

- Put long-form content here: excerpts, evidence links, edge cases, FAQ
- Keep \`SKILL.md\` Quick Reference short and directly usable

## Goals

- Define the 10 most important terms in this domain
- Provide the shortest path from zero to working

## Suggested Structure

- Organize by use case, not alphabetically
- Key parameters: defaults, boundaries, common misuse
- Common errors: message -> cause -> fix steps

# Long Examples

Put examples longer than ~20 lines here, split by use case:
