ofa14-prog/Loop ? reverse-engineered prompt

Build me a TypeScript tool called LoopGuard that watches OpenTelemetry traces from an autonomous agent and tells me when it looks stuck or is wasting time.

I want it to catch repeated tool calls, no progress loops, bad arguments showing up over and over, and sudden token cost spikes, then turn that into a simple health score from 0 to 100. It should accept trace data over HTTP, work with both JSON and protobuf, and expose a health check and metrics endpoint too.

Please include a small terminal dashboard that shows the current score, recent spans, and live verdicts, plus a way to export results as NDJSON and JUnit XML for CI. It should also have a CLI so I can run it in server mode, evaluate a saved trace file, or generate a report. Keep the core logic dependency free if possible, and add tests so the main detection rules are covered. If you need to check anything, look up current docs online.
