Supported Agents

New to agents? Agents explains what an agent is, and Creating your own agent writes one. Every agent below runs on any sandbox provider and calls the model endpoint in [model].

Claude Code is the default agent, so any step that doesn't name an agent deploys it. It needs a model endpoint that speaks Anthropic's API, such as a LiteLLM gateway, and the agents README covers the rest.

{"id": "assistant", "type": "deploy_agent", "env_ids": ["email"], "a2a_agent_id": "pi"}

[agents]
default_a2a_agent_id = "pi"   # every step and agent judge that names no agent

pi is Earendil's open-source coding agent, and it works with any model endpoint that speaks the OpenAI API. Give it a model with [model] default, and the pi README covers the rest.

{"id": "assistant", "type": "deploy_agent", "env_ids": ["email"], "a2a_agent_id": "openhands"}

OpenHands is an open-source coding agent, which AgentEnv runs through the OpenHands SDK, and it calls its model through a LiteLLM endpoint. Give it a model with [model] default, and the OpenHands README covers the rest.
