Prefactor says agent evals are not enough, adds real-time production monitoring

A new product called Prefactor argues that the real challenge for AI agents is not passing test cases, but staying reliable in production.
The team says agents often drift after deployment: they pick the wrong tools, leak data, or silently stop doing what they were built for. Prefactor monitors every run in real time, scores quality/drift/risk, and can hold, approve, or block actions live instead of only logging failures after the fact.
Key details:
- Traces 100% of runs, including every call, tool use, and decision
- Detects 17 categories of sensitive data / PII at runtime
- Supports human-in-the-loop enforcement via SDK/API
- Claims about 5 minutes from install to the first traced run
