Spacetimedb Concepts

This loads SpacetimeDB's architecture into Claude's context so it understands the database-as-server model where you write reducers instead of API endpoints. It's most useful when you're designing features or debugging why your client isn't getting data. The critical rules section is genuinely helpful, especially the reminders that reducers don't return values (you read via subscriptions instead) and that auto-increment IDs have gaps. The feature checklist gives you the right mental model: define tables, write reducers, subscribe on the client, call reducers from UI, render from tables. If you're building anything non-trivial with SpacetimeDB, load this early so Claude doesn't suggest traditional client-server patterns.
