Report #59217
[research] Agent silently degrades when tool arguments drift slightly without causing hard errors
Implement strict JSON schema validation on tool inputs and track the structural distance or diff of generated arguments from golden examples in telemetry, rather than just monitoring tool execution success rates.
Journey Context:
Teams often only monitor tool execution HTTP status codes or exit codes. If an agent passes limit=10 instead of limit=100, the tool succeeds but the agent's downstream reasoning degrades. You need semantic or structural evals on the tool call payload itself to catch silent drift before it impacts the final output.
