AdCP Sponsored Intelligence (SI) Protocol

What it does

Provides a concise implementation and reference for the AdCP Sponsored Intelligence (SI) Protocol so an agent can start brand conversations, preview product offerings, exchange messages in-session, and cleanly terminate sessions. Includes field-level guidance for consent-aware identity, offering tokens, placements, and error handling for real conversational commerce flows.

When to use it

Use this skill when a user needs to engage with a brand agent for product exploration, transactional handoffs, or any conversational commerce scenario where explicit consent and session lifecycle management are required. Also use when building host integrations that must preview offerings before requesting PII.

What's included

• Scripts: none detected in repo (has_scripts=false) — this is primarily a protocol reference
• References: none detected (has_references=false) — the SKILL.md contains task-level examples and request/response schemas
• Instructions: detailed task reference for four tasks (si_get_offering, si_initiate_session, si_send_message, si_terminate_session), consent model, placements, and common error codes

Compatible agents

Best suited for agents that can call structured APIs or follow task schemas (Copilot/Codex-style or server-backed agents). Works well in environments that can manage session state and tokens (server-side or agent runtimes).
