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 • Configuration • References
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.
# Add marketplace (one time)
/plugin marketplace add fcakyon/claude-codex-settings
# Install any plugin by name
/plugin install < plugin-name > @claude-settings
Codex installs plugins from a local marketplace rather than a direct shell install command.
.agents/plugins/marketplace.json./plugins.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.
gemini extensions install --path ./plugins/<plugin-name>
cursor plugin install < plugin-name > @claude-settings
Create symlinks for cross-tool compatibility:
ln -sfn CLAUDE.md AGENTS.md
ln -sfn CLAUDE.md GEMINI.md
| Claude Code | Codex CLI | Gemini CLI |
| ----------------------------------------------------- | ----------------------------------------------------------------------------- | ---------------------------------------------------------------- |
| /plugin install intelligent-compact@claude-settings | Open /plugins -> Claude & Codex Settings -> install intelligent-compact | gemini extensions install --path ./plugins/intelligent-compact |
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:
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| Claude Code | Codex CLI | Gemini CLI |
| -------------------------------------------------------- | --------- | ------------------------------------------------------------------- |
| /plugin install claude-telemetry-hooks@claude-settings | n/a | gemini extensions install --path ./plugins/claude-telemetry-hooks |
Adds the two missing pieces Claude Code's telemetry needs to power a usage dashboard:
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_iduser_prompt_reject_feedback.py - UserPromptSubmit hook that categorizes tool-rejection reasons| Claude Code | Codex CLI | Gemini CLI |
