Medley
About Medley
Medley is a plugin for Claude Code and Codex that transforms a single prompt into a structured multi-agent plan. It breaks down complex tasks into sequential or parallel steps, assigning each to an appropriate agent such as Claude Code, Codex, Cursor, OpenCode, Kimi, or Pi. The tool provides a terminal command, /mission or $medley:mission, to initiate the process and generates a URL for viewing the task tree, status, and handoffs in a browser. Medley integrates with popular development and productivity tools like GitHub, GitLab, Slack, Notion, Linear, and AWS, enabling workflows that extend beyond a single coding session. It is designed for users who need to coordinate multiple agents to achieve goals such as research, outreach, documentation, or project management without requiring a separate application. The plugin operates within the existing terminal environment, adding multi-agent decomposition and execution capabilities to the user’s current workflow.

Frequently asked questions about Medley
What does /mission actually do?
The /mission command takes a user prompt, such as 'get my first 10 customers,' and converts it into a structured multi-agent plan. It defines the target, budget, deadline, and initial checks before coordinating a team of agents to execute the steps.
Is Medley a replacement for Claude Code?
No, Medley is a plugin that enhances the existing tools you already use, such as Claude Code or Codex. It adds multi-agent decomposition, parallel execution, and a visual mission board without requiring a separate application.
Why does /mission beat a single model?
Medley runs a coordinated multi-agent plan, which can involve parallel agents or different models for different steps. This approach outperforms a single model working alone by distributing tasks and leveraging specialized capabilities.
Does Medley act without my permission?
No, Medley operates within guardrails set by the user. It requests permission before performing sensitive actions such as publishing, sending outbound messages, spending, or contacting people. Users can grant more autonomy as they become comfortable.
What does it cost?
Medley itself is free to use. It relies on the models you already have access to in Claude Code or Codex, so there are no additional costs for the models themselves.
How do I install Medley?
Installation involves adding the Medley plugin to your existing environment. For Claude Code, use the marketplace command to add the plugin, then install and reload it. For Codex, follow similar steps with the Codex-specific commands.
