cmux-workspace SKILL.md skillB

cmux-workspace from basicmachines-co/basic-memory is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add basicmachines-co/basic-memory/cmux-workspace@git:20260823.9007836

Pins git:20260823.9007836 in mdr.lock. Pin the fingerprint instead.

Work inside the current cmux workspace and terminal. Use for cmux workspace, current workspace, caller surface, panes, surfaces, socket targeting, and non-interfering cmux automation.

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

# cmux Workspace

Scope work to the cmux workspace that invoked the agent.

- **Window**: a macOS cmux window.
- **Workspace**: a sidebar entry. The UI calls it a tab; CLI/socket APIs call it a workspace.
- **Pane**: a split region inside a workspace.
- **Surface**: a tab inside a pane, terminal or browser.
- **Panel**: internal content type inside a surface. Prefer CLI surface commands over panel internals.

## Default rule

Scope actions to the current caller workspace unless the user explicitly asks for another workspace, another window, or global state. Do not assume the visually focused workspace is the right target: an agent can run in one workspace while the user looks at another.

```bash
printf 'workspace=%s\nsurface=%s\nsocket=%s\n' \
  "${CMUX_WORKSPACE_ID:-}" "${CMUX_SURFACE_ID:-}" "${CMUX_SOCKET_PATH:-}"
cmux identify --json
```

`CMUX_WORKSPACE_ID` is the default workspace anchor and `CMUX_SURFACE_ID` the default caller terminal anchor. If they are missing, fall back to `cmux identify --json` and say explicitly that you are using the currently focused context.

## Non-disruptive automation

How to install

The exact contents, by fingerprint
mdr add basicmachines-co/basic-memory/cmux-workspace@sha256:1c8e787a74c4694a

The line at the top of this page pins the label git:20260823.9007836, 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.
