Assessment

This issue has not been assessed yet.

Description

needs review
Is your feature request related to a specific problem?

LLM request/response content and tool arguments/responses will no longer be captured in OpenTelemetry spans unless explicitly opted in.

ADK should provide a privacy-first default to avoid UGC being accidently extracted, aligning with OTEL conventions.

Describe the Solution You'd Like

Tracing.java — The default value of the ADK_CAPTURE_MESSAGE_CONTENT_IN_SPANS environment variable should default from true → false.

Impact on your work

Various systems need to explicitly set the environment variable to false in order to opt-out of the feature.
