# Integration Playground

## Contract

- Input: JSON fixture definition, an optional executable plus argument array, and a temporary output directory.
- Output: disposable playground directory; when a command is supplied, its exit status, stdout, stderr, and command evidence.
- Boundary: output must be under the system temporary directory; only Node.js commands run with a minimal environment and commands never pass through a shell.

Run `node .agents/skills/platform/skill-lab.mjs playground --output /tmp/quirk-playground --fixtures '{"api":{"status":"ok"}}' --command '["node","script.mjs"]'`. Never point it at a production directory or pass credentials into a playground command.
