The faster your team ships with AI, the harder it becomes to keep production stable. Not anymore. Coldtea is an agentic IDE where your coding agents build, visual QA agents catch regressions, and AI monitoring watches production, so your team can keep moving at agent speed without breaking anything
This is the 2nd launch from Coldtea. View more
PR Lens by Coldtea.ai
Launched this week
PR Lens is a new way to look at code. It draws animated architecture and data flow diagrams of any codebase and every pull request, so you see the change before you read a single line of code. It runs as a GitHub Action, on the CLI, or as a skill for your coding agent. Open source under MIT.
Launch Team / Built With
PR Lens is the part I want. I ship solo with a coding agent and the hard bit is understanding what it changed before I merge. Does it make sense with no second human reviewing, or is it built for teams?

@lmfresneda For solo use, it's better to use it locally with your coding agent.
Install via the Skill and ask your agent to use the skill to explain anything.
You'd be surprised how clear and helpful the visuals are
@ohansemmanuel Thanks for the tip! I'll give it a try :)

This solves a real pain we hit building automation workflows: agents generate diffs faster than any human can read them, and the actual review bottleneck isn't diff size, it's building a mental model of what moved. Curious how the diagram holds up on changes that touch config/infra files versus pure logic changes, those tend to have very different "shapes" and I'd guess harder to render meaningfully. Starred the repo.

@pushpendraw It actually does a good job here cos its not about single entities. So you may have a diagrammed [INFRA] engine connected to the rest of the system. Give it a try, best way to see it at work :)
This is such a fantastic way to review PRs! Sifting through hundreds of lines just to grasp what actually changed can be a real drag 😅
Getting a glimpse of the architecture and data flow first adds that crucial visual element that often feels absent between the PR desscription and the code itself. Plus, the combination of the GitHub Action and the open source aspect makes it even more intriguing. I am definitely eager to see how it perrforms with larger codebases.

@jacob_hernandez4 Give it a try! Its as simple as copying a prompt and your coding agent sets it all up :)
@ohansemmanuel sure i will give it a try,good luck with the launch, i up voted for you .
I think the biggest shift here is treating code review as a comprehension problem, not just a line-by-line comparison problem. That feels increasingly important as AI-generated PRs get larger.
congrats on the launch! 🙌
the mental model part really hits. i run a few claude code agents in parallel worktrees, and after a day of merges i genuinely lose track of what moved where. scrolling the diff doesn't fix that. "watch the request travel through the system" is exactly what i keep wishing for.
adding the skill and pointing it at my last messy PR, THANKS for shipping this 👍
