What it does
coldstart gives a coding agent persistent, self-maintaining memory of your codebase — a notebook it writes itself, plus a fast static index to find the right file without wasted reads. No embeddings, no API key — it runs on the model you already pay for. It is a a single‑purpose tool for codebase memory & navigation by building a knowledge graph.

coldstart gives it persistent memory of your codebase — a notebook it writes itself, so what one session figures out, the next already knows — plus an exact index to find the right file without three wrong reads . No embeddings, no API key: it runs on the model you already pay for. An agent writes down what it learns while it works. The next one starts where that one finished instead of searching for it again, checked against the code so a stale note never passes as fact. Persists a map tile and its geometry. save() is the single write path — it stamps bbox from the geometry before insert, so callers must never set bbox by hand. Commit the notebook to your repo and the whole team feeds one…from coldstartmcp.dev

Clipto MCP▲655Hey 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…

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…
