SDK
One ergonomic surface, six languages
The SDK speaks the language of an agent remembering things. Each verb maps 1:1 to an operation in the OMEM standard. There are no hidden semantics, and you can always drop to the raw operations when you need to.
The verbs
Verb

remember(agent, *, about, claim, because=None)

Prototyping offline? Client(embedded=True) runs the reference engine in-process: identical semantics, zero network, no key. Flip to cloud by removing one argument.
