Runtimes and routing
Supported worker runtimes#
- Claude Code — workers spawn via the Claude Agent SDK, using your subscription auth.
- Codex — add Codex workers to the pool with the
codexCLI, logged in viacodex login. - Cursor — add Cursor workers with the
agentCLI, logged in viaagent login.
Any subset works. Medley auto-discovers whichever of these are installed and logged in, and routes only among the runtimes actually present.
What a worker inherits#
Each worker is a fresh agent session that starts with your full setup: skills, MCP servers, project memory, permission grants, and subscription auth. That is why a worker behaves like you would in that repo, not like a blank assistant.
Bring your own keys#
Medley is BYOK. Missions run on the models you already have access to. The plugin itself is free; the cost is your own agent usage.
Where routing is decided#
Routing is part of the plan you approve — each task in the graph shows the runtime and model it will use, before anything runs. See the task DAG.
