Battle-tested Claude Code, Claude Desktop, OpenAI Codex, and Cursor setup with skills, commands, hooks, subagents, and MCP servers, plus Kimi, MiniMax, and GLM API support.

_"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.

<details open> <summary><strong>Claude Code</strong></summary>

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

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

In Claude Code desktop, select + beside the prompt, then Plugins and Add plugin.

</details>

<details> <summary><strong>Codex CLI</strong></summary>

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

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

In the Codex desktop app, open Plugins, find the plugin, and select Install.

</details>

<details> <summary><strong>Gemini CLI</strong></summary>

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

</details>

<details> <summary><strong>Cursor</strong></summary>

# Add marketplace (one time)
cursor-agent plugin marketplace add https://github.com/fcakyon/claude-codex-settings

# Start the interactive CLI
cursor-agent

Enter /plugin, open the marketplace, and install the plugin at user or project scope. In the Cursor app, open Customize and select Install.

</details>

Want the shared agent guidance too? .claude/CLAUDE.md is the file written for your projects. Run /claude-tools:sync-claude-md to pull it into ~/.claude/CLAUDE.md, or paste it into a project as CLAUDE.md, then point the other tools at the same file:

ln -sfn CLAUDE.md AGENTS.md # Codex CLI, Cursor, Copilot
ln -sfn CLAUDE.md GEMINI.md # Gemini CLI

Plugins

<details> <summary><strong>simplify</strong> - Review changed code for reuse, redundancy, and over-engineering, then apply fixes</summary>

Run /simplify to review your staged or committed diff across four angles (reuse, simplification, efficiency, altitude) with parallel agents, then apply the cleanups. It reviews changed-code quality, not correctness bugs. It brings Claude Code's built-in /simplify to Codex, Cursor, and Gemini, which don't ship it natively, so all three get the same review and apply flow.

Skills:

• simplify - review the changed diff across four angles and apply the fixes

Hooks:

• guard.py - Require a completed /simplify run before each Claude Code or Codex commit, unless you explicitly ask to skip it for one commit

</details>

<details> <summary><strong>humanize</strong> - Write naturally and block AI buzzwords in files, commits, and messages</summary>

Before a Write or Edit saves, humanize scans the new text and blocks whatever reads like a machine wrote it, each hit paired with a plain-word swap. It reads Markdown files whole and checks comments and docstrings in code files while skipping source code and recognized code-shaped references:

• 3 marks: the em-dash, section sign, and stray semicolon (the en-dash stays)
• 53 stock words like leverage, seamlessly, vibrant, game-changing, each mapped to a plain swap
• 16 openers and cliches like in conclusion, a testament to, aims to bridge
• 10 pile-up words like crucial or significant, flagged at 3+ uses in one write

Runs on Claude Code and Gemini. Unlike a markdown rule the model can ignore, the hook checks every Write or Edit and blocks each match until it is replaced. The word list draws on Wikipedia's "Signs of AI writing".

Skills (ZIP for claude.ai, ChatGPT, Claude Code, Cursor, Codex, VS Code):

Skill	Description	ZIP
humanize	Avoid common AI writing patterns with examples

Hooks:

• humanize.py - blocks matched marks, buzzwords, and cliches before a Write or Edit lands

</details>

<details> <summary><strong>fable-advisor</strong> - Get a second opinion from Claude Fable 5.1 before big decisions</summary>

Ask a Fable 5.1 reviewer to challenge a plan or conclusion before you commit. Claude Code uses the native plugin agent, while Codex, Cursor, and Gemini call the same model through an authenticated Claude Code CLI with claude -p --model claude-fable-5-1.

Agents:

• fable-advisor - Native Claude Code reviewer with recent conversation context

Skills:

• fable-advisor - Routes Claude Code to its native agent and other tools to claude -p

</details>

<details> <summary><strong>codex-advisor</strong> - Get a second opinion from GPT-6 Astra via Codex CLI before big decisions</summary>

Ask GPT-6 Astra to challenge a plan before you build it, the cross-model check the built-in advisor cannot give you. Claude Code attaches the recent conversation, so "ask the codex advisor" is enough. Codex, Cursor, and Gemini reach the same reviewer. Needs the Codex CLI signed in.

Agents:

• codex-advisor - Sends the recent conversation to GPT-6 Astra and returns the verdict verbatim

Skills:

• codex-advisor - Routes Claude Code to its native agent and other tools to codex exec

</details>

<details> <summary><strong>adhd-output-style</strong> - Use fewer output tokens with short steps, quick insights, and clear next actions</summary>

Cuts filler and keeps output token use down with the answer or next step first, one-action-per-step lists, concrete time estimates, a single under-two-minute next action, and short teaching notes while coding. Claude Code applies the output style automatically. Codex, Cursor, and Gemini CLI expose the same instructions as an adhd-output-style skill because they do not support plugin output styles.

Output styles:

• ADHD Explanatory - Low-token ADHD formatting plus educational Insight blocks while coding

Skills (ZIP for claude.ai, Claude Code, Cursor, Codex, VS Code):

adhd-output-style	Apply the same reply format in Codex, Cursor, and Gemini CLI

</details>

<details> <summary><strong>intelligent-compact</strong> - Keep file paths, root causes, and open questions through auto-summaries</summary>

When Claude Code auto-summarizes a long session, the default summary routinely drops the highest-signal facts. This plugin tells the summarizer to keep them:

• File paths under investigation so the next turn doesn't re-discover where you were
• Confirmed root causes so you don't re-debug what's already solved
• Open questions, metrics, and IDs that prose summaries usually round away
• Findings from expensive subagent runs that took minutes to gather

Runs on every /compact (manual) and every auto compaction. Claude Code only; Codex, Cursor, and Gemini CLI don't yet expose a comparable summary hook.

Hooks:

• precompact_priorities.sh - Priority-preservation instructions for the compaction summarizer

</details>

<details> <summary><strong>claude-telemetry-hooks</strong> - Track Claude Code usage, rejections, and session stats in one dashboard</summary>

Adds the two missing pieces Claude Code's telemetry needs to power a usage dashboard:

• Sticky session ID per project: resumed conversations stay one session, not dozens
• Categorized rejection reasons (profanity, wrong target, scope drift, retry, and more): chart why Claude pushes back

Per-device data is already in Claude Code's built-in OpenTelemetry stream. Pairs naturally with openobserve-skills for the dashboard side.

Hooks:

• session_start_chat_id.py - SessionStart hook that emits a sticky per-project chat_id
• user_prompt_reject_feedback.py - UserPromptSubmit hook that categorizes tool-rejection reasons
