Examples, not opinions
When Breakspec finds a problem, it shows you the simplest example that breaks your code. You can run it yourself.
How Breakspec compares
AI reviewers read your code and tell you what might be wrong. Breakspec runs it and shows you an example that breaks it.

What you get with Breakspec
You decide what correct means
Your agent can suggest rules. Only a person can approve them, and only approved rules can block a merge.
No AI bill per pull request
Rechecking your rules doesn’t use AI, and gives the same answer every time. A busy repository costs the same as a quiet one.
Fixes get checked
Breakspec reruns the example that failed, keeps it for every future run, and notices a fix that only special-cases it.
Works with any agent
Claude Code, Cursor, Codex or code written by hand. Run it from your terminal, on every commit, or on every pull request.
Your code stays yours
Checks run on your machine or in your CI, cut off from the internet. AI requests use your own key, and only after you say yes.
