Prelint reads every PR against your specs, ADRs and prior decisions, and explains what the agent chose and why it matters — before merge. On teams already running other AI reviewers, ~40% of pre-merge fixes come from Prelint.

We just launched Prelint on Product Hunt 🚀

The bug isn't the scary part of AI-written code. Working code that quietly builds the wrong product is.

I've watched changes pass human review AND CI, then turn out to have broken an architectural pattern, added an unapproved dependency, or changed a permission rule nobody ever decided to change.

Nothing failed. It just wasn't what we agreed to build.

How to TDD

1. Write the code
2. Write the tests
3. git rebase -i to reorder your commits

Learning to disassemble other apps and system frameworks to understand how they work has to be one of the most underestimated skills in app development.

@speirin @talixocom @Zendesk I guess you won't receive any photos. As far as I am concerned Talixo doesn't have the office in Monaco, or am I wrong?

My friend left her MacBook Pro on a Manhattan park bench.

Timeline:

Within 5 minutes: laptop gone
Within 6 hours: laptop in Bronx
After 7 days: in the Dominican Republic

Fascinating how stolen electronic logistic networks work, and how they don’t properly reset the hardware
