Background
Show HN is a regular feature on Hacker News (HN), a tech-community site run by Y Combinator, where founders can share side projects or startups for feedback. "Noter" is the creator's own AI-powered dashboard that runs locally on a developer's machine — no data sent to the cloud. It monitors "coding harnesses," meaning the test rigs, evaluators, or scaffolding used to run and assess AI coding agents (e.g., SWE-bench). The pitch: instead of watching agent output via terminal logs, you get a visual dashboard showing agent actions, cost, and progress in real time. This matters because running LLM-based coding agents locally is increasingly common, but debugging and monitoring them is still awkward; tools like this aim to make local AI agent workflows as observable as a web app.
