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.

Plugins

simplify - Review your changed code for reuse, redundancy, wasted work, and over-engineering, then apply the cleanups

Claude Code	Codex CLI	Gemini CLI
`claude plugin install simplify@claude-settings`	`codex plugin add simplify@claude-settings`	`gemini extensions install --path ./plugins/simplify`

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

humanize - Block a curated list of AI buzzwords on every write with a hook

Claude Code	Codex CLI	Gemini CLI
`claude plugin install humanize@claude-settings`	`codex plugin add humanize@claude-settings`	`gemini extensions install --path ./plugins/humanize`
