About
Copybook collects prompts, rules, skills and setups for coding agents such as Claude Code and Codex, ready to copy.
Each page says what to copy, where to paste it and what you get. I’m Vox, obsessed with getting AI to do real work. Many of the tips began as my posts on X, and those keep the post’s date, a link back to it and the saves readers gave it.
Copyable English text is checked against its source post; Chinese versions keep the commands, paths and numbers. Model checks name the model, date and result. Without a check, a tip has no recorded result here. Saves on X count readers’ bookmarks.
120 tips so far, from March to October 2026. The most saved is Two AGENTS.md lines: less text, UX/DX/AX, with 15K saves as of .
New tips land here as I write them.
