The Leaked AI Tool Prompts

The real system prompts behind Cursor, Claude Code, Devin, v0, Lovable, Windsurf and 22 more tools are sitting in one public GitHub repo with 142,000 stars. Here is how to actually use them instead of just starring it.

01Free, GPL-3.0
Open the repo
It is x1xhlol/system-prompts-and-models-of-ai-tools on GitHub. 28 tools, one folder each, still being updated (last commit 12 July 2026). Nothing to buy, nothing to sign up for.
02Start with one
Pick the tool closest to what you build
Building a coding agent? Read Cursor and Claude Code. Building a site generator? Read v0 and Lovable. Doing research or browsing? Read Perplexity or Comet. One folder, not all 28.
03The real lesson
Read the structure, not the words
Do not copy their text. Notice the shape: who the model is, what it must never do, how tools are described, how the output format is pinned down, and how edge cases get handled before they happen.
04Where it pays off
Move the structure into your own setup
Put those same sections into your CLAUDE.md, your custom GPT, or your agent's system prompt. That is the difference between a prompt that works once and one that works every time.
The skeleton almost every one of them uses
# 1. identity You are X. You do Y for Z.
# 2. hard rules Never do A. Always do B.
# 3. tools When to call each one, and when not to.
# 4. output Exact format, with an example.
# 5. edge cases If unclear, ask. If blocked, say so.
