Prefactor launches real-time AI agent evaluation layer

Prefactor is a real-time evaluation layer designed for engineering teams deploying AI agents to end users. It continuously scores agent runs in real time, exposes queryable execution traces, and establishes runtime governance boundaries to catch regressions and contain high-risk actions.

// ANALYSIS

Offline evaluations are no longer sufficient for non-deterministic AI agents, making continuous production scoring the new standard for reliability.

–Evaluates every live agent run in real time to spot quality regressions and behavioral drift before users do.
–Provides runtime safety boundaries that restrict or flag unvalidated agent actions during feature rollouts.
–Offers queryable execution traces across popular AI frameworks like OpenAI, Claude, LangChain, and MCP servers.
