## FAQ

### How does external-agents help reduce costs?

It allows your primary agent to hand off tasks to a pool of 40+ cheaper or free-tier models instead of using expensive frontier models for every task.

### What happens if a provider reaches its rate limit?

The server automatically moves to a different provider and honors that provider's specific reset time.

### Can I use this with existing CLI tools like Claude Code or Cursor?

Yes, it is designed to work with agentic CLIs like Claude Code, OpenAI Codex, Cursor, and others.

### How do I add new API keys to the pool?

You can use the local dashboard provided by the installation to paste your provider keys inline.
