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.

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

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

# Install any plugin by name
/plugin install < plugin-name > @claude-settings

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

Codex installs plugins from a local marketplace rather than a direct shell install command.

1. Clone this repo locally and open it in Codex.
2. This repo already includes .agents/plugins/marketplace.json.
3. If Codex was already open when you added or changed that file, restart Codex.
4. In Codex, open /plugins.
5. 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.

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

gemini extensions install --path ./plugins/<plugin-name>

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

cursor plugin install < plugin-name > @claude-settings

Plugins

<details> <summary><strong>intelligent-compact</strong> - PreCompact hook that preserves high-signal context in auto-compact summaries</summary>

Claude Code's auto-compact summarizes long sessions to fit the context window, but the default summary routinely drops the highest-signal facts: file paths under investigation, confirmed root causes, remaining tasks, unanswered questions, metrics and IDs, and findings from expensive subagent runs. This plugin ships a single PreCompact hook that injects A-F fidelity requirements on top of the 9-section default compact prompt, so those categories survive every /compact (manual) and every auto compaction. Active on Claude Code only; Codex, Cursor, and Gemini CLI do not yet expose a PreCompact hook.

Hooks:

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