Install felix 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 felix@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 “felix” remain stable.

Codex: felix@agent-plugin-marketplace → felix@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/felix/.

Included Skills1

use-felix-cliskills/use-felix-cli/SKILL.md

Use when the user asks about Felix, agent scaffolding, agent standards, maintainer agents, repo health for an agent, pre-scaffold interviews, have/want/dont-want framing, AGENTS.md wakeup files, plugin setup placement, or whether a new agent should exist. This skill tells Codex to call the installed `felix` CLI first and use `felix-of-felix` only for maintaining public Felix itself.
