Use when creating, developing, building, publishing, migrating, or reasoning about SpacetimeDB database modules. Covers local development, module build/publish flow, transactions, automatic migrations, incremental migrations, and the database cheat sheet. Triggers on: database module, spacetime publish, build module, migration, transaction, atomicity, developing module.
Use when writing SpacetimeDB reducers, lifecycle reducers, scheduled reducers, reducer context code, table mutations, indexed lookups, reducer isolation logic, or reducer error handling. Triggers on: reducer, ReducerContext, ctx, sender, client_connected, client_disconnected, init, scheduled reducer, insert row, delete row, update row.
Use when migrating from SpacetimeDB 1.0 to 2.0 or fixing code affected by 2.0 breaking changes. Covers reducer callbacks, event tables, event type changes, subscription API, table accessor naming, database-name connections, `sender()` method, update methods, scheduled functions, private codegen, light mode, `CallReducerFlags`, and confirmed reads. Triggers on: upgrade, migrate, 1.0, 2.0, breaking changes.
Use when implementing SpacetimeDB authentication or authorization, including SpacetimeAuth, Auth0, Clerk, OIDC, auth claims, subject/issuer checks, custom claims, roles, row-level security, and rejecting client connections. Triggers on: auth, authentication, authorization, SpacetimeAuth, Auth0, Clerk, OIDC, claims, RLS, row-level security.
Use when running or explaining SpacetimeDB CLI commands and standalone configuration. Covers `spacetime init`, `build`, `publish`, `generate`, `call`, `sql`, `logs`, `describe`, `dev`, `server`, `start`, login/logout, and `config.toml`. Triggers on: spacetime CLI, spacetime publish, spacetime generate, spacetime sql, spacetime logs, spacetime server.

Use this skill for C# and Unity client implementation.
Generate C# bindings and use the generated DbConnection, RemoteTables, and RemoteReducers names from the user's project:
spacetime generate --lang csharp --out-dir client/module_bindings --module-path spacetimedb
var conn = DbConnection.Builder()
.WithUri(new Uri("ws://localhost:3000"))
.WithDatabaseName("my-database")
.OnConnect((conn, identity, token) =>
{
conn.SubscriptionBuilder().SubscribeToAllTables();
})
.OnConnectError((ctx, err) => Log.Error(err.ToString()))
.OnDisconnect((ctx, err) => Log.Info("Disconnected"))
.Build();
conn.FrameTick() from the main loop or Unity update path; callbacks and cache updates will not be applied otherwise.FrameTick() on a background thread while main-thread code reads conn.Db.conn.Db.<Table>.Iter(), Count, and generated unique/index handles.OnInsert, OnDelete, and OnUpdate; OnUpdate requires a primary key.conn.Reducers.<ReducerName>(...) and register generated reducer events when needed.| Need | Open |
