What it does
AI agents are deployed everywhere but nobody knows what they'll cost or how much damage they could cause. AgentShield predicts cost, scores risk, and estimates blast radius BEFORE execution. - Risk Score: 0-1000 safety score per agent - Cost Prediction: know the cost before spending a token - Blast Radius: estimate max damage from permissions - Real-time Detection: flags hallucinations and leaks - Approval gates for high-risk actions LangChain, CrewAI, OpenAI SDK. 3 lines of Python. Free tier

AgentGuard – Auto-kill AI agents before they burn through your budget2025 · github.com · ▲47Your 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…

Agent Shield 2025 · kya.vouched.id · ▲15Hey HN, AI agents are all the buzz right now, but how many of them are accessing your website today? That's what we built AgentShield to answer.

Feedback welcome: What else would you want to know about AI agents visiting your site?
AgentShieldJan 2026 · github.com · ▲5Hey, I'm Gong Chao, currently working at Zai. Last weekend after playing football and heading home, an idea suddenly popped into my head. I got the urge to build it and spent the whole weekend hacking it out — *AgentShield* . Nowadays everyone's using Cowork, Claude Code, or various AI agents to manipulate files and write code. It's awesome, but sometimes AI goes "crazy" and messes up your files, making it impossible to revert to the original state (don't ask me how I know... ). For code, you have Git, but that requires commits, and it's not friendly for large files. AgentShield puts a…
