Codex Review
A cross-model review skill that sends your plan or code diff to OpenAI Codex for independent verification. The value of cross-model review is that different models have different blind spots — Codex may catch issues that Claude misses, and vice versa.
The skill operates in two modes (auto-detected):
- Plan Review: when you have an implementation plan, Codex challenges it for completeness, risks, and alternatives
- Code Review: when you have a git diff, Codex inspects the actual code for bugs, security issues, and edge cases
In both modes, Claude doesn't just relay feedback — it actively revises the plan or proposes fixes based on Codex's input, then re-submits for re-review. This continues until Codex approves or 5 rounds are reached.
Prerequisites
codexCLI installed and on PATH (npm install -g @openai/codex)- OpenAI credentials configured (API key or ChatGPT login)
Verify with: codex --version

web-fetcher
Fetch any URL as clean markdown. Use instead of WebFetch for JS-rendered pages, login-required platforms (Twitter/X, zhihu, reddit, weibo, xiaohongshu, bilibili, etc.), and complex pages. Routes known platforms through OpenCLI (browser login state), others through Jina Reader / defuddle.md / markdown.new. Invoke when the user provides a URL to read, extract, summarize, or convert to markdown.
45notion-lifeos
User's personal Notion LifeOS (PARA: tasks, notes, projects, Make Time journals) with pre-configured DB IDs + API access — required for any LifeOS interaction. Use for adding tasks, taking notes, journaling, querying todos, searching notes, creating projects, reflection. Triggers: 'add task', 'take a note', 'what do I need to do', 'search my notes', '加个任务', '查笔记', '待办', '记录想法', '反思', '目标偏移'. Not for Notion API docs or workspace admin.
6cmux
Use this skill for ANY multi-pane or multi-agent terminal orchestration in cmux. Required when the user wants to: run things in parallel in separate terminal panes, split the terminal, spawn a sub-agent (Claude Code, Codex) in another pane, fan out tasks across splits, send keystrokes or text to another pane (including ctrl-c), read terminal output from another pane, update sidebar status or progress bar, open a URL in cmux's built-in browser pane, or display markdown preview alongside the terminal. The cmux CLI is the ONLY way to do these things — Bash cannot split panes or spawn agents. Trigger phrases: 'in parallel', 'split pane', 'spawn agent', 'fan out', 'new pane', 'browser pane', 'sidebar', 'send to pane', 'read from pane', 'show the plan', 'ctrl-c to', '分屏', '并行', '开个 pane'. NOT for: single command execution, basic bash operations, or questions about tmux.
5scholar-agent
Use this skill for anything related to academic paper discovery, filtering, reading, or management. Invoke for: browsing today's papers, getting paper recommendations, rating/collecting papers, deep-reading papers via NotebookLM, adding arXiv papers to NotebookLM, asking questions about papers, or checking trending research. This skill wraps the Scholar Inbox REST API and notebooklm-py CLI (recommended to install together for deep reading). Triggers: 'scholar inbox', 'paper digest', '看论文', '读论文', '论文推荐', 'rate papers', '收藏论文', '帮我筛选论文', '今天有什么论文', 'paper reader', 'deep read paper', 'trending papers', 'arXiv'. NOT for: reading PDFs, fetching web pages, writing literature reviews, general note-taking, or managing non-paper NotebookLM notebooks.

4project-review
Strategic project review — automatically discovers and reads strategy documents (vision, roadmap, decisions, meeting notes, experiments), then generates a five-dimension analysis snapshot. Use when the user wants to review project direction, check strategic alignment, assess milestone progress, or get a quick overview before a team meeting. Triggers: 'project review', 'review the project', 'strategic review', 'where is the project at', 'project status overview', '项目全景', '审视战略', '战略 review', '项目现在什么状态', 'review 一下方向'. NOT for: code review, PR review, or any code-level review — this skill is about strategy, not code.
