medley

claudecodex

[DEV CHANNEL — Medley dev team only] Prerelease Medley builds, used to test engine and daemon upgrades before they reach the stable channel. Expect breakage. Install this INSTEAD of the stable medley plugin, never alongside it: the two share ~/.medley, port 8730, and one background daemon. Missions inside Claude Code: give /mission a goal and Medley plans the work, then supervises execution until the goal is met.
