AdCP Governance Protocol

This skill enables you to execute the AdCP Governance Protocol with governance agents. Covers four areas: property lists (site-level targeting), collection lists (program-level targeting), content standards (brand safety rules), and campaign governance (plans, checks, outcomes, audit trail).

Buyer-side basics — idempotency replay, oneOf variants, async status:'submitted' polling, error recovery from adcp_error.issues[] — live in skills/call-adcp-agent/SKILL.md. This skill covers per-task semantics only.

Overview

The Governance Protocol provides 21 standardized tasks across four areas:

Property Lists

Collection Lists

Content Standards

Campaign Governance

Experimental in 3.0. Campaign governance may change between 3.x releases with at least 6 weeks' notice. Sellers MUST declare governance.campaign in experimental_features to participate. See experimental status.

Typical Workflow

Property Lists (site-level)

1. Create list: create_property_list with base properties and filters
2. Resolve: get_property_list with resolve: true to see matched properties
3. Refine: update_property_list to adjust filters
4. Apply: Reference list_id in create_media_buy targeting

Collection Lists (program-level, CTV)

1. Create list: create_collection_list with distribution IDs or genre filters
2. Resolve: get_collection_list with resolve: true to see matched programs
3. Apply: Reference in campaign targeting for CTV brand safety

Content Standards

1. Create standards: create_content_standards with rules
2. Calibrate: calibrate_content with test samples to validate configuration
3. Monitor: get_media_buy_artifacts + validate_content_delivery for ongoing compliance

Campaign Governance

1. Sync governance agents to seller accounts via sync_governance (lives in the Accounts protocol)
2. Register the plan: sync_plans with budget authority, channel allocation, and resolved policy IDs
3. Validate actions: check_governance on intent (pre-discovery) and execution (pre-buy). Returns an opaque governance_context token the seller echoes on subsequent checks.
4. Report outcomes: report_plan_outcome so committed/remaining budget advances
5. Audit and produce shareable views: get_plan_audit_logs filtered by governance_contexts for the requesting party. See audit trail: internal vs shareable views.
