Report #14637

[research] Agent silently fails by passing malformed arguments to tools without throwing exceptions

Implement strict JSON schema validation on tool inputs at the orchestration layer, and log/track schema validation failure rates as a primary agent health metric.

Journey Context:
Agents often adapt to API changes by passing subtly wrong types \(e.g., string 'true' vs boolean true\) or omitting optional fields that are contextually required. These don't raise API errors but cause downstream logical errors. Relying on tool execution success/failure masks these. Schema validation catches this at the boundary before the tool executes.
