Installation
Plugins add skills, commands, and automations to your AI coding tool. Install only what you need from the plugin list below.
Prerequisites: See INSTALL.md for setup requirements.
Claude Code
# Add marketplace (one time)
/plugin marketplace add fcakyon/claude-codex-settings
# Install any plugin by name
/plugin install < plugin-name > @claude-settings
Codex CLI
Codex installs plugins from a local marketplace rather than a direct shell install command.
- Clone this repo locally and open it in Codex.
- This repo already includes
.agents/plugins/marketplace.json.
- If Codex was already open when you added or changed that file, restart Codex.
- In Codex, open
/plugins.
- Choose
Claude & Codex Settings and install the plugins you want.
This README only covers installing this marketplace.
For generic Codex marketplace examples and maintainer docs, see CLAUDE.md.
Gemini CLI
gemini extensions install --path ./plugins/<plugin-name>
Cursor
cursor plugin install < plugin-name > @claude-settings
Create symlinks for cross-tool compatibility:
ln -sfn CLAUDE.md AGENTS.md
ln -sfn CLAUDE.md GEMINI.md
Plugins
fable-advisor - On-demand second opinion from Claude Fable 5 to pressure-test a plan, interpretation, or risky change before you commit to it
| Claude Code | Codex CLI | Gemini CLI |
|---|
/plugin install fable-advisor@claude-settings | Open /plugins -> Claude & Codex Settings -> install fable-advisor | gemini extensions install --path ./plugins/fable-advisor |
Spawn a stronger Fable 5 reviewer to pressure-test a plan or conclusion before you commit, a drop-in for the built-in advisor when the Opus-main plus Fable-advisor pairing fails with a bare "unavailable" (#73365). It checks your load-bearing claims against the actual files and returns a skeptical review, not a rewrite.
Agents:
fable-advisor - Fable 5 second-opinion reviewer, pass it the task, your approach, and the evidence
intelligent-compact - Stop Claude Code from forgetting file paths, root causes, and open questions when it auto-summarizes long sessions
