Sierra published the draft Personal Agent Protocol, called Poppy, on October 9. Its announcement names Instinct among the partners involved in the original unveiling earlier that week and adds 35 design partners. The proposal is broader than an agent-to-agent chat channel: it describes how personal agents discover a business, identify themselves, obtain customer-authorized access and carry a session across websites, APIs and a company’s own agent.
For Instinct, participation points toward more explicit ways to complete errands than navigating ordinary websites while signed in as a person. The draft supports company-defined access boundaries and builds on existing standards, including OAuth, JWTs, OpenAPI and MCP. Sierra describes forthcoming design workshops and a reference implementation, so the publication should be read as a standards-development milestone. The demonstration cited in the article used Meta’s Muse, not Instinct.
Editorial take: Shared sessions could reduce repeated logins and lost context during a complicated task. The meaningful test will be whether businesses implement the permissions consistently across channels. A partner list alone does not establish a working integration with every company named.
