What it is

Claude‑Codex‑Settings is a collection of plug‑ins that add extra skills, hooks and agents to several AI‑coding assistants – Claude Code, Anthropic Codex, Gemini and Cursor. The repo bundles ready‑to‑install extensions that make these tools smarter, safer and more consistent when you write or edit code.

Main features

Plugin	What it does	Where it works
simplify	Reviews a diff for reuse, over‑engineering and inefficiency, then can apply the suggested clean‑ups.	Claude Code, Codex CLI, Gemini CLI
humanize	Scans new text for AI‑style buzzwords, clichés and “machine‑written” markers and blocks the write until they are replaced with plain language.	Claude Code, Gemini CLI
fable‑advisor	Sends the current conversation to Claude Fable 5.1 for a second opinion before a commit.	Claude Code, Codex CLI, Gemini CLI
codex‑advisor	Same idea but uses the GPT‑6 Astra model via the Codex CLI.	Claude Code, Codex CLI, Gemini CLI
adhd‑output‑style	Forces a low‑token, step‑by‑step reply format (short actions, time estimates, concise insights).	Claude Code (auto), Codex CLI, Gemini CLI
intelligent‑compact	Improves Claude Code’s automatic session summaries by preserving file paths, root‑cause notes and open questions.	Claude Code only
claude‑telemetry‑hooks	Emits per‑project session IDs and categorises rejection reasons for a usage dashboard.	Claude Code, Gemini CLI
anthropic‑office‑skills / openai‑office‑skills	Adds PDF, Word, PowerPoint and Excel processing capabilities using the official Anthropic or OpenAI skill libraries.	Claude Code, Codex CLI, Gemini CLI

Each plug‑in ships a skill (the command you invoke, e.g. /simplify), optional hooks that run automatically (e.g. guard against committing without a simplify run), and sometimes agents that talk to a remote model.

How to install

1. Add the marketplace for the tool you use (Claude Code, Codex CLI, Gemini CLI, or Cursor).
2. Install a plug‑in by name, for example:

   claude plugin install simplify@claude-settings   # Claude Code
   codex plugin add simplify@claude-settings       # Codex CLI
   

3. Some plug‑ins provide a ZIP file with the skill definition that can be loaded into other editors (VS Code, etc.).

Who might use it

• Developers who already use Claude Code, Codex or Cursor and want extra automated code‑review, style enforcement, or document‑processing capabilities.
• Teams that need consistent behaviour across different AI‑coding environments (the same /simplify command works in Claude, Codex and Cursor).
• Anyone looking to add telemetry or enforce “human‑like” writing standards in AI‑generated code or documentation.

Limitations

• Some plug‑ins only work in Claude Code (e.g., intelligent‑compact).
• The “advisor” plug‑ins require access to the respective remote models (Claude Fable 5.1, GPT‑6 Astra) and appropriate authentication.
• The repository does not contain the AI models themselves – it only provides the glue that connects existing tools to them.

---

In short: Claude‑Codex‑Settings is a curated marketplace of extensions that make AI‑coding assistants more disciplined, less verbose, and better at handling office documents, all via simple install commands.
