I built a tool to catch AI agents getting stuck in loops

I built AGENT-SIM — a tool for detecting AI-agent execution loops

I built AGENT-SIM, an open-source tool for analyzing AI-agent tool execution trajectories.

It can detect patterns like:

  • Repeated tool loops
  • Alternating tool loops
  • Repeated failures
  • Excessive cumulative latency

When a failure is detected, it can create a failure capsule containing the trajectory, analysis, and structural fingerprint.

It also supports replaying trajectories to check whether the same structural behavior can be reproduced.

The v2.0 release includes:

  • Authenticated telemetry gateway
  • Structural trajectory analysis
  • Failure capsules
  • Structural fingerprints
  • Replay support
  • CLI tools
  • Automated tests

I'd love feedback from developers working with AI agents: What would you want a tool like this to detect or analyze next?
