claude-codex-settings: Enhance Your AI Coding Tools with Battle-Tested Configurations

Introduction

The claude-codex-settings repository by fcakyon is a comprehensive collection of battle-tested configurations, plugins, hooks, and agents designed to enhance your AI coding experience. It supports popular AI coding tools like Claude Code, OpenAI Codex, and Cursor, providing a robust framework to improve their performance and reliability. This project addresses common pitfalls in AI-generated code, such as incorrect assumptions and overcomplication, by offering structured guidelines and an extensive plugin ecosystem. Furthermore, it extends its utility by supporting Kimi, MiniMax, and GLM APIs, making it a versatile asset for developers leveraging advanced AI models.

Installation

Plugins add skills, commands, and automations to your AI coding tool. Install only what you need from the plugin list. For detailed setup requirements, refer to the project's INSTALL.md file.

Claude Code:

# Add marketplace (one time)
claude plugin marketplace add fcakyon/claude-codex-settings

# Install any plugin by name
claude plugin install fable-advisor@claude-settings

Codex CLI:

# Add marketplace (one time)
codex plugin marketplace add fcakyon/claude-codex-settings

# Install any plugin by name
codex plugin add simplify@claude-settings

Gemini CLI:

# Install any plugin by name
gemini extensions install --path ./plugins/simplify

Cursor:

# Install any plugin by name
cursor plugin install simplify@claude-settings

The repository also provides shared agent guidance in .claude/CLAUDE.md, which can be synced to your local setup for consistent behavior across tools.

Examples

The claude-codex-settings repository features a rich collection of plugins, each designed to address specific development needs. Here are a few notable examples:

Simplify

The simplify plugin helps review changed code for reuse, redundancy, and over-engineering, then applies necessary fixes. It evaluates code quality across four angles: reuse, simplification, efficiency, and altitude, using parallel agents. This plugin brings Claude Code's built-in /simplify functionality to Codex, Cursor, and Gemini, ensuring consistent code review across your preferred tools. It also includes a guard.py hook to require a completed /simplify run before each commit.

Installation Example (Claude Code):

claude plugin install simplify@claude-settings

Humanize

The humanize plugin is designed to block a curated list of AI buzzwords and cliches, ensuring your written content reads more naturally. Before a "Write" or "Edit" action, it scans new text, comments, and docstrings for common AI writing patterns and suggests plain-word swaps. This hook-based plugin runs on Claude Code and Gemini, enforcing a more human-like tone in your documentation and code comments.

Installation Example (Claude Code):

claude plugin install humanize@claude-settings

GitHub Dev

The github-dev plugin offers a suite of agents and skills for automating Git and GitHub workflows. It includes agents like commit-creator for intelligent commit messages, pr-creator for pull request generation, and pr-reviewer for code reviews. Its skills cover tasks such as committing staged changes, creating pull requests from branch diffs, reviewing PRs for bugs, and resolving comments. Hooks are also provided for commit and PR creation confirmations, and to block AI attribution lines.

Installation Example (Claude Code):

claude plugin install github-dev@claude-settings
