What it does

Most AI agent security tools filter inputs before they reach the model. Sentinely works inside the pipeline, scoring every action before it executes. It detects prompt injection, tracks each agent's behavioral baseline and flags drift, quarantines suspicious memory writes, and catches multi-agent manipulation. Every action is logged with a full audit trail for SOC2 and EU AI Act compliance. 3-line integration. Works with LangChain, CrewAI, OpenAI, and Vercel AI SDK.

    Hi HN! We’re the team behind Fiddler, and we recently built an Agent Cache feature. It works by capturing an LLM request/response pair and, once caching is enabled, serving subsequent matching calls locally so duplicate requests never hit the provider. It’s meant to reduce three pains that show up together in agent development: token cost, feedback-loop latency, and output non-determinism. We’d love to hear your thoughts.
