# Requirements Gate

For any skill that depends on external skill sets (e.g., Superpowers), enforce these rules:

## Mandatory Prerequisite Section in SKILL.md

Include a `Prerequisites` section that states:

- required dependency repo
- required skill names
- what happens if requirements are missing
- exact remediation steps

## Runtime/Flow Behavior

If requirements are missing:

1. Stop execution.
2. Return a concise blocking message.
3. Provide exact install/setup steps.
4. Ask for confirmation once requirements are installed.

## Suggested Block Message

```text
Cannot run <skill-name> yet.
Missing required Superpower skills: <list>
Install from: https://github.com/obra/superpowers
After installation, tell me "requirements ready" and I’ll continue.
```

## Compatibility Requirement

Each skill must declare support for:

- Codex
- Claude Code
- OpenCode

If one platform is unsupported, state it explicitly.
