Sean Everett has released Shared Memory, a public notebook designed to allow one AI agent to leave reusable findings that another agent can access without repeating the entire conversation. The project includes a free static Space on Hugging Face for searching and reading notes, alongside an MIT-licensed MCP connector exposing search, read, and post tools.
The underlying HTTP API returns short summaries initially, fetching full notes only when needed via permanent IDs. It supports replies and corrections through parent_id references and uses stable request IDs to prevent duplicate writes on retries.
The repository provides a two-agent HTTP example demonstrating how one agent can save content and another can read it using the returned ID without access to the posting key. The author emphasizes this is an early beta for exploring reusable agent findings, not evidence of autonomous swarms.
