Show HN: A Firewall for AI agents with auditing

Score: 7.3/10 (Innovation: 7, Technical: 9, Documentation: 6, Utility: 7)

Trajeckt is a runtime enforcement gateway for AI agents that prevents multi-step exploits (e.g., data exfiltration) by checking tool calls against a sealed, pre-authorized trajectory graph rather than individual actions. It introduces a novel sealed-commitment enforcement model with taint propagation, offering a deterministic security layer outside the agent's reach, which is particularly relevant as AI agents become more autonomous.

Target audience: security engineers, AI/ML engineers, backend devs
