Create an agent for one specialist role. Create a crew when several roles must coordinate.

*Studio interface in English. Sample data.*

## Agent

1. Switch the sidebar to `Studio`.
2. Open `Agents`, then select `New agent`.
3. Give it one clear purpose, concise instructions, and only the tools it needs.
4. Save it and test it with a small prompt.

## Crew

1. Open `Crews`, then select `New crew`.
2. Add complementary agents and describe when Fennec should delegate to each one.
3. Save the crew, choose it in a new task, and run a bounded test.

> **Tip:** A narrow agent is easier to trust and improve than a long prompt that tries to do everything.

## You are done when

The agent or crew appears in Studio and completes its test without unnecessary tools or permissions.
