AI agents can already use tools and coordinate, but their memory is fragmented across project files, agent notes, local stores, databases, and vendor-specific systems. Move to a new tool and the context is gone.

UMP v0.1 is a shared format plus a simple way to read, write, update, and move agent memory across tools. The goal is memory that's user-owned, auditable, and extensible across agents and runtimes, instead of locked inside one vendor.

It's early (v0.1) and I'd love feedback on the format and where it breaks down. Repo and spec are linked from the site.

integration with 3rd parties (mcp, skills) worked because there was no way github/jira type services would support >2 integrations

any other feature being compatible between harnesses makes transitioning from one to another too easy

so, the only way memory will work, similar to {AGENTS,CLAUDE}.md, is if everyone uses: base path + markdown files
