cmux is a macOS multiplexer that organizes agent sessions into a topology of windows, workspaces, panes, and surfaces, where a surface can be a terminal or a browser panel. The 22-skill cluster documents operating it end to end: browser panels, testing, dev workflow, backend, customization, diagnostics, keyboard shortcuts, and release/billing internals. The core skill defines the topology explicitly: window → workspace → pane → surface.

CorpusIQ Use Cases¶
| Use Case | How |
|---|---|
| Agent workstation layout | Window/workspace/pane/surface topology for running research alongside browser inspection |
| Browser panels | cmux-browser as a lightweight alternative to separate browser windows during agent work |
| Dev workflow reference | cmux-dev-workflow and cmux-testing patterns for structured agent development loops |
| Multi-surface monitoring | Side-by-side terminal + browser panels for cron debugging sessions |
Integration with CorpusIQ¶
CorpusIQ is the connector layer that lets AI assistants read the systems a business already runs on - accounting, payments, CRM, email, files and analytics - and answer with the source named. It is read-only by design: it retrieves data and never writes to, or acts in, a connected system, which is what makes it safe to point at live accounts.
This page is part of the CorpusIQ directory, the reference we maintain for the MCP server and agent-skill ecosystem. Run alongside CorpusIQ, a third-party server like this one can be combined with a company's own business data in a single answer.
Limitations / Verification¶
- macOS only - no Linux or Windows surface
- Value requires running cmux itself; the skill cluster documents the tool
npx skills add manaflow-ai/cmux --skill cmux # verify install works
