# Skill Finder

Full-featured Agent Skills management tool.

## When to Use

- **Find skill**, **search skill**, **install skill**, **スキル検索**
- Looking for skills for a specific task or domain
- Finding and installing skills locally
- Managing favorites with star feature
- Checking whether the ask really calls for a skill before recommending one

## Recommendation Gate

Before searching, check whether the user really wants a **skill**.

| If the ask sounds like...              | Prefer...   |
| -------------------------------------- | ----------- |
| Single slash task                      | Prompt      |
| Always-on or file-scoped guidance      | Instruction |
| Persona, tool restrictions, delegation | Agent       |
| Deterministic enforcement              | Hook        |
| Reusable packaged workflow             | Skill       |

If the answer is not **Skill**, explain that first instead of forcing a skill recommendation.
