Tips & gotchas
- Extend your assistant. Custom skills are how you add capabilities beyond the built-in set.
- Fully automated. The assistant writes the code, tests it, and packages it — you just describe what you want.
- High-risk classification. Skill source file modifications always require approval to prevent privilege escalation.
- Review before approving. Check the generated code before granting approval. You can also edit skill files directly if you prefer.
