Report #5302

[research] Agent silently degrades without throwing exceptions or failing tasks

Implement outcome-based assertions and trace-level telemetry on tool inputs/outputs, not just HTTP status codes. Track semantic drift using embedding distance between expected and actual tool arguments.

Journey Context:
Agents often return 200 OK but pass malformed or subtly wrong arguments to tools \(e.g., passing user\_id instead of email\). Standard APM catches latency/errors but misses semantic failures. You need observability at the LLM-tool boundary, logging the exact payload the LLM generated for the tool call, and asserting it against a schema or semantic expectation.
