Drive the Rex terminal multiplexer: tabs, panes, splits, and hosts. Load this when opening a file alongside the user, starting a dev server or log tail the user should watch, reading another terminal's output, running a command on a saved host, or asking what else is running. Tab, pane, split, and host are Rex's terms. In a session Rex hosts, a request that uses one is a Rex request even when it never says Rex. New PR-bound work goes to `dispatch:dispatch`.
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
Rex hosts this session's tabs and panes. A tab is a window and a pane is a block. For general mechanics (IDs, flags, client actions), run `rex __internal skill`.
## Current Session
!`bun ${CLAUDE_SKILL_DIR}/scripts/orient.ts`
One line per tab, then one per block: ID, label, foreground cwd, and program. `*this*` marks the block running this session. If it prints a failure instead of a listing, stop here and use ordinary tools.
## Splits
Default to a sibling split of `$REX_BLOCK` under `$PWD` that leaves focus where it is:
```bash
rex split -s "$REX_SESSION" -b "$REX_BLOCK" --split=right --focus=false -c "$PWD" --json
```
Split `right` on a wide pane and `below` on a tall one, alternating direction across successive splits. A new tab, session, or host needs the user to ask for it. Take the new block from `.block_ids[0]`.
Close only blocks you opened. A pane you split for the user to read counts as theirs.
## Collaborative File Viewing
Open the file beside this pane so the user watches it change. Use `markless --watch` for markdown and `$EDITOR` for everything else:
```bash

How to install
mdr add bendrucker/claude/rex@sha256:e86f14925d91e64bThe line at the top of this page pins the label git:20261030.3e26a65, 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.
