Metadata-only tracing gives AI agents privacy-first observability

Short summary

Metadata-only tracing for AI agents captures execution behavior without storing raw prompts or responses by default. The approach uses typed, operation-specific metadata schemas with controlled vocabularies to answer operational questions while keeping sensitive payloads out of traces. Every metadata field still needs a purpose, owner, and retention policy since metadata itself can be sensitive.

• •Metadata-only tracing records agent behavior without storing raw payloads by default
• •Typed schemas with controlled vocabularies prevent sensitive data leakage into trace fields
• •Versioned trace envelopes support parent-child relationships and long-term compatibility
