My daily battle-tested Claude Code/Desktop and OpenAI Codex setup with skills, commands, hooks, subagents and MCP servers.

"They make wrong assumptions on your behalf and just run along with them without checking. They don't manage their confusion, they don't seek clarifications, they don't surface inconsistencies, they don't present tradeoffs. They really like to overcomplicate code and APIs, they bloat abstractions, they don't clean up dead code after themselves." -- Andrej Karpathy

This repo's guidelines are structured to fix exactly these pitfalls.

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
