## What is PandaProbe?

PandaProbe is an open-source agent engineering platform that gives you deep observability into AI agent applications. Use it to trace, evaluate, monitor, and debug your AI agents in development and production — and, with the harness, let your agents heal themselves.

## Why PandaProbe?

PandaProbe is a unified platform for the full agent development lifecycle — from first run to continuous improvement. 

PandaProbe provides:

  <Card title="Tracing" icon="route">
    Capture LLM calls, MCP calls, tool usage, workflow steps, and custom agent logic as structured traces and spans.
  </Card>
  <Card title="Evaluation" icon="drafting-compass">
    Score traces and sessions to measure quality, reliability, regressions, and agent behavior over time.
  </Card>
  <Card title="Monitoring" icon="clock">
    Schedule recurring evaluations so new traces and sessions are checked automatically in production.
  </Card>
  <Card title="Self-Healing Harness" icon="shield-check">
    Wrap your agent in an operational envelope that detects quality degradations, lets the agent diagnose its own failures, and validates the operating rules it learns — automatically, with no human in the loop.
  </Card>

## Three layers of tracing

1. **LLM Providers** — zero-code wrappers for major providers
2. **Agent Frameworks** — automatic integrations for agent frameworks
3. **Manual instrumentation** — full control when you need it
