Report #39768

[synthesis] Error originates in Tool A, but message propagates through B and C, causing agent to 'fix' component C while root cause A remains, creating infinite loops of futile patches

Implement distributed tracing semantics: inject correlation IDs through tool calls, require tools to distinguish 'internal error' vs 'invalid input', and force root cause analysis before allowing fixes on downstream components

Journey Context:
In distributed systems, error propagation is well-understood \(cascading failures\), but agents treat tool errors as atomic events. Single sources discuss try/catch or error messages, but miss the synthesis: when Tool A \(search\) returns bad data that Tool B \(calculator\) errors on, the agent sees B's error and 'fixes' the calculation, never realizing A fed it garbage. This is the 'blame the messenger' anti-pattern. The fix requires treating the agent-tool chain like a microservices mesh: distributed tracing \(OpenTelemetry\), error classification \(4xx vs 5xx\), and circuit breakers. This bridges distributed systems observability with agent tool design.
