The Agent Memory Interchange (AMI) spec is out: an open format for portable AI agent memory

[Fmarzochi]

Every AI coding tool builds a memory of your project, and every one of them locks that memory inside itself. Switch tools and you start from zero.

Today EGC ships the first draft of the Agent Memory Interchange (AMI) specification: an open, plain-text format for portable AI agent memory.

What it defines

• One Markdown document per memory scope (project, branch, user-wide global)
• Five sections: Context, Active Decisions, Do Not Repeat, Preferences, Next Session
• Deterministic merge semantics: prepend with caps, Next Session replaced on every update
• Scope precedence: branch over project over global
• Export and import behavior, with mappings for CLAUDE.md, AGENTS.md, GEMINI.md, Cursor native memories and free-form notes

EGC is the reference implementation: the spec documents the exact format egc-memory already ships in production. The spec exists so it does not have to be the only implementation.

Read it: docs/spec/agent-memory-interchange.md

Feedback is very welcome, here or in issues. If you maintain another agent tool and want it to speak AMI, the conformance section (Section 9) was written for you. The reference egc export / egc import pair is next on the roadmap.

Your agent's memory should belong to you, not to your tooling vendor.
