PR Lens by Coldtea.ai

In plain words

PR Lens is a tool that generates animated architecture and data flow diagrams for codebases and pull requests, allowing developers to visualize changes before reading code. It integrates with GitHub as an Action, runs on the CLI, or works as a coding agent skill. The tool uses visual elements like depth, color, and glyphs to highlight new code, modified sections, and deletions within the broader system context. It is open source under the MIT license and designed to streamline code review by emphasizing system structure over line-by-line diffs.

From the sources

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.

PR Lens draws what matters as animated architecture and data flow diagrams, inside the PR itself. Review the shape of the change, not a wall of diff.

A custom renderer built for humans. With zero cognitive overload See what truly matters before you read any line of code. Software is changing. The way we read it is as well Depth, weight, glyph and colour carry meaning. Not dark lines on white boxes. What is new, what was touched and what was taken out, visually linked. You see it before you read it. A pull request touches one part and moves several. The parts it did not touch stay on the page, so you build a model of the system rather than a patch See how the system moves and connect the dots faster.Animation is usually a distraction. Here it is intentional diff --git a/app/api/broadcasts/queue/route.ts b/app/api/broadcasts/queue/route.ts…from prlens.dev

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
