  • NEW PrysmAgentMiddleware — captures agent run execution (start/end, timing, messages, metadata).
  • NEW PrysmFunctionMiddleware — captures function/tool calls (name, arguments, result, timing).
  • NEW PrysmChatMiddleware — captures LLM chat completions (messages, options, response, tokens).

  • NEW Unified Timeline — correlated view of LLM traces, tool events, and session events.
  • NEW Tool Performance Dashboard — success rates, latency distributions, failure analysis.
  • NEW Agent Decision Explainability — trace backward to find why an agent chose a specific action.

Governance Layer & LangGraph Integration

  • NEW GovernanceSession — context manager for monitoring agent sessions with behavioral detection, code scanning, and policy enforcement via MCP.
  • NEW Early Stopping detector — catches agents that quit before completing their stated task.
  • NEW Tool Undertriggering detector — identifies when agents have tools available but fail to use them.
  • NEW Code Security Scanner — scans agent-generated code for injection flaws, hardcoded secrets, unsafe deserialization, and more.
