Manage AI agent fleets in a Rex terminal: tile root + workers in one tab, start/prompt/wait/read them, check what they do, steer fleet panes; `help` lists all. Don't use for Herdr, tmux, or one-off Rex tabs, splits or commands.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Rex Agent Build and control an AI-agent fleet in the root agent's Rex window. Keep the **root block** as orchestrator; add each **worker** as a right-hand column running the main agent's own launch profile; equalize all columns; then prompt, wait, read, monitor, steer, or tear down through the `rex` CLI and this skill's scripts. A **session** holds **windows** (tabs), and a window holds **blocks** (panes). Rex has no agent registry and no prompt-and-wait call, so the scripts add both: a worker's **name** is its block label, and its **status** is the OSC 7501 program status record its own CLI reports. For everyday Rex commands outside fleet work, `rex skill show` prints the guide that matches the installed CLI. Relay reply deltas rather than whole screens to protect the context and token budget. ## Choose the Workflow | Request | Follow | |---|---| | `help`, or what this does and how to drive it | Help in `references/help-request.md` — answer and stop | | Spawn workers beside root | Phases 1–2, then 4–6 if assigning work | | Message an existing agent | Phases 3–5 | | Give several workers different tasks | Phases 3 and 7 (`dispatch`) | …

How to install
mdr add luongnv89/skills/rex-agent@sha256:56759f10f2326492The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
