Phinq

In plain words

Phinq is an open source runtime governance layer that intercepts AI agent tool calls to prevent harmful actions. It classifies each call by risk level, allowing safe actions to proceed while requiring human approval for irreversible operations. Every decision is recorded in a tamper-evident audit log, providing verifiable proof of human oversight. The tool sits at the network boundary, ensuring agents cannot bypass its controls. It is designed for teams deploying AI agents who need to prevent unintended or dangerous actions.

From the sources

Phinq is an open source runtime governance layer for AI agents. It intercepts every agent tool call, classifies it by risk, lets safe actions pass, holds irreversible actions for human approval, and records each decision in a tamper-evident hash-chained audit log.

Your agent does things you'd never approve. Phinq stops the dangerous ones before they happen. And asks you first. Your agent tries to do something. Phinq sees it before it happens. Your phone buzzes. Approve or deny. Denied means the agent never even got to run it. People asked an agent to run something safe. Then it tried something it shouldn't. Phinq stopped it. Most tools watch your agents. Phinq proves a human was in the loop. Every decision on a tamper-evident log you can verify. A prompt asks the agent nicely. Phinq sits at the network boundary. The agent cannot ignore it. Paste the setup prompt into your agent. It installs Phinq, connects itself, verifies it works. No control plane…from phinq.co

  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…
