AdCP Measurement Agents

Measurement agents are first-class provider identities without requiring AdCP to become a universal measurement-data transport.

Calling basics — authentication, idempotency, error recovery, and account resolution live in skills/call-adcp-agent/SKILL.md. This skill covers measurement-specific semantics.

Role

A measurement agent can:

1. publish the metrics it computes through get_adcp_capabilities.measurement.metrics[];
2. declare measurement.produces_performance_feedback: true when it produces optimizer-ready assertions;
3. obtain buyer-approved data from an orchestrator through its get_media_buy_delivery task; and
4. return compact assertions through its provide_performance_feedback task, after which the orchestrator decides what to send to each seller.

The measurement agent never needs seller credentials. The orchestrator controls cohort consistency, seller-ID mapping, normalization, and disclosure. report_usage is a vendor-service consumption and billing task, not general measurement interchange.
