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?
