VinVAI
Install Vinv once, give coding agents a verification layer
What it does
Vinv is an IDE plugin that auto-exposes its MCPs to all coding harnesses on your system. It gives harnesses the same runtime information and context about the repo you are working on, connects runtime traces to the source code, provides context for the coding agents, and reruns the code to verify that the fix works. It uses Thompson sampling to figure out how much runtime context to give the agent. Everything runs locally. Open source, Apache 2.0.
Tools and Algorithms for AI agents to test, fix and optimise your codebase. Vinv runs your Python services with zero code changes, hands your agent real runtime evidence, then re-runs the code to verify the fix. 100% local, Apache 2.0.
Install once. Every agent on the repo reads the same runtime context. One install. Every agent gets the same context. Vinv is not another coding agent — it is the evidence layer under the one you already use. No editor needed. Claude Code, Codex, Gemini CLI — every Vinv tool, in whatever harness you drive. Engines build in a terminal you can watch; a one-time ~500 MB local embedding model downloads. Needs uv , Rust , and an agent CLI you already pay for. No account, no keys, about four minutes. vinv-mcp · PyPI · source Filed on scikit-learn , FastAPI , Typer , watermarks-remover , graphify . Every screenshot links to the thread. All of it driven by Cursor running Composer 2.5 with Vinv…from vinv.ai

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…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
