AgentGuard
Governance kernel for AI agents trust, approvals, audit logs
What it does
If your agent can break AgentGuard, Bitcoin has bigger problems than AgentGuard. AI agents can access databases, move money, and operate critical systems. Most teams give them broad permissions with little oversight. AgentGuard adds trust scoring, capability-based permissions, approval gates, and immutable audit logs, ensuring every action is verified, accountable, and governed before it happens. Control your AI before your AI controls your business.

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, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
