Use this skill for procedures and server-side work that is not a reducer transaction entrypoint.
Procedures are server functions that can return values and perform work that reducers should not do, including external HTTP calls. Use reducers for client-invoked transactional state changes; use procedures when the caller needs a return value or the function must do external work.
TypeScript procedure shape:
export const add_two_numbers = spacetimedb.procedure(
{ lhs: t.u32(), rhs: t.u32() },
t.u64(),
(_ctx, { lhs, rhs }) => BigInt(lhs) + BigInt(rhs),
);
Language notes:
t.* type and receive (ctx, args).#pragma warning disable STDB_UNSTABLE and use [SpacetimeDB.Procedure].unstable feature and use #[spacetimedb::procedure] with &mut ProcedureContext.SPACETIMEDB_UNSTABLE_FEATURES before including the header.ctx.withTx(...).| Need | Open |

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.
