getvibekits/vibe-coding-rules

Free, copy-paste AGENTS.md, CLAUDE.md and Cursor rules (.cursor/rules/.mdc) for 30 beginner project types: games, bots, web apps, websites, mobile apps, scripts, AI agents and backends, plus sets made for Lovable, Bolt, Replit Agent and Base44 projects.
Each set gives your AI coding tool (Claude Code, Cursor, OpenAI Codex, GitHub Copilot, Lovable, Bolt) the same working rules: one task at a time, a short plan before code, the smallest change that works, secrets kept out of code, no destructive commands without asking, plus 6 rules specific to the stack.
Browse the full library, with an explanation of why each rule exists, at getvibekits.com/rules, or build a custom file in the free rules generator (runs in your browser, no signup).

## Quick start
1. Find your project type in the table below.
2. Copy its AGENTS.md into the root of your project and fill in the [brackets].
3. Using Claude Code? Also copy CLAUDE.md (it just imports AGENTS.md).
4. Prefer Cursor Project Rules? Copy the .cursor/rules/ folder instead of AGENTS.md.
5. Commit the files, so every session (and every teammate) gets the same rules.
