AgentShield
A safety shield. One-click rollback when AI goes crazy.
What it does
Nowadays, more and more people use Cowork & Claude Code to manipulate files locally. It's powerful — but sometimes AI goes crazy and completely messes up your workspace, making it impossible to revert to the original state. AgentShield puts a safety shield around your local workspace. It monitors file changes in real time, and when things get messed up, you can rollback everything with one click — basically a regret pill for AI. Free & open source.

Your AI agent hits an infinite loop and racks up $2000 in API charges overnight. This happens weekly to AI developers. AgentGuard monitors API calls in real-time and automatically kills your process when it hits your budget limit. How it works: Add 2 lines to any AI project: const agentGuard = require('agent-guard'); await agentGuard.init({ limit: 50 }); // $50 budget // Your existing code runs unchanged const response = await openai.chat.completions.create({...}); // AgentGuard tracks costs automatically When your code hits $50 in API costs, AgentGuard stops…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
