```

Your agent:

1. Signs you in. You approve a link on any device, and new users create an account there. The key is saved for the agent and never shown in chat.
2. Connects Autumn the way you need: MCP tools, the CLI or your project's code.
3. Checks your credits, installs the [Skill](/docs/skill), and starts on your research.

The agent's instructions are at [agent-quickstart.md](https://www.autumn.ai/agent-quickstart.md).
