Install emux for Codex and Claude Code

Installs for the current user
codex plugin marketplace add eidos-agi/eidos-marketplace
codex plugin marketplace upgrade eidos-agi
codex plugin add emux@eidos-agi

Paste and run these commands in a terminal with Codex. They add and refresh the eidos-agi catalog, then install this plugin.

Compatibility: the page URL and API slug “emux” remain stable.

  • Codex: emux@agent-plugin-marketplace → emux@eidos-agi

The installer fetches third-party code from the source repository shown on this page. This directory validates manifest structure and source location, but does not perform a security audit; review the manifest, components, and source before installing.

Get the source manually
git clone https://github.com/eidos-agi/eidos-marketplace

Clone the source repository, then follow its setup instructions to add the plugin to a compatible client. The plugin root is plugins/emux/.

Included Skills1

nested-managerskills/nested-manager/SKILL.md

Push a noisy or long-running drive loop DOWN a level so it doesn't fill your context. Spawn a manager session that itself spawns and drives a sub-session; you only talk to the manager. Use when driving a session would generate lots of capture/send churn (a long TUI task, a chatty remote build, a multi-step agent job) — especially on a remote box.

MCP servers1

emuxstdio
command
uv
args
run --directory ${CLAUDE_PLUGIN_ROOT}/. emux mcp

MCP configuration uses runtime-provided plugin path placeholders such as ${PLUGIN_ROOT} or ${CLAUDE_PLUGIN_ROOT}. Review the manifest for the runtime-specific expansion rules.
