# Skill Sandbox & Testing

> Test skills in isolation before publishing.

Use the sandbox API to test a skill without publishing it:

```bash theme={null}
POST /api/v1/skills/sandbox
```

The sandbox executes the skill's system prompt extension and tools against a test prompt, returning the result without billing or persisting anything.

## Local Testing

1. Create your skill with `defineSkill()`
2. Run `theo skill validate` to check the manifest
3. Use per-request skills to test without installing:

```typescript theme={null}
const res = await theo.complete({
  prompt: "Test: check stock for SKU-123",
  skills: ["my-skill-slug"],
});
```
