About Claude Codex Settings

A personal open-source repository containing battle-tested configurations, plugins, hooks, subagents, and MCP servers for Claude Code, Claude Desktop, OpenAI Codex CLI, Cursor, and Gemini CLI. Includes plug-and-play plugins like 'simplify' (reviews changed code for reuse, redundancy, over-engineering, and efficiency with parallel agents) and 'humanize' (blocks AI buzzwords in comments and markdown). Supports additional AI APIs including Kimi, MiniMax, and GLM. Designed to fix common pitfalls in AI-assisted coding—such as unnecessary complexity, lack of clarity, and unchecked assumptions—by providing structured guidelines and automations.

Key Features

Plugin marketplace integration for Claude Code, Codex CLI, Gemini CLI, and Cursor
Simplify plugin: parallel-agent review of diffs for reuse, simplification, efficiency, and altitude with auto-fixes
Humanize plugin: automatically blocks AI buzzwords in markdown, comments, and docstrings on write
Cross-tool compatibility via symlinks (AGENTS.md, GEMINI.md)
Support for Kimi, MiniMax, and GLM API integration
Subagents and MCP server configurations for extended automation
Multiple configuration files (CLAUDE.md, CODE.md, GEMINI.md) for tool-specific behavior

Pros & Cons

Pros
  • Open-source and completely free to use
  • Works across four major AI coding tools (Claude Code, Codex, Cursor, Gemini)
  • Plugins address real pain points: code bloat, AI buzzwords, and missed simplifications
  • Simple installation via tool-specific marketplace commands
  • Community-driven with battle-tested configurations from daily use
  • Includes both standalone plugins and full-configuration files for quick onboarding
Cons
  • Requires manual symlink creation for cross-tool consistency
  • Primarily a personal configuration set; may not cover all team or enterprise needs
  • Plugins are tied to specific tool versions and may break with future updates
  • Documentation is limited to the GitHub README; no dedicated support or tutorials

FAQ

What AI coding tools does this repository support?
It supports Claude Code, Claude Desktop, OpenAI Codex CLI, Cursor, and Gemini CLI, with additional API support for Kimi, MiniMax, and GLM.
How do I install a plugin?
Each tool has its own marketplace command. For example, for Claude Code run `claude plugin marketplace add fcakyon/claude-codex-settings` then `claude plugin install simplify@claude-settings`. For Codex CLI use `codex plugin add simplify@claude-settings`. See the installation section in the README for all tools.
What does the simplify plugin do?
It reviews your changed code across four angles (reuse, simplification, efficiency, and altitude) using parallel agents, then applies the cleanups automatically.
What does the humanize plugin do?
Before a write or edit saves, it scans the new text and blocks a curated list of AI buzzwords (e.g., 'leverage', 'seamlessly', 'vibrant') and suggests plain-word swaps. It reads markdown files wholly and only comments/docstrings in code.
