Add Serverpod authentication — serverpod_auth_idp packages, initializeAuthServices, identity providers (Email, Google, Apple, etc.), Flutter sign-in UI, migrations. Use when adding authentication or a new social sign-in to a Serverpod project.
Serverpod caching — local and Redis caches, cache keys, lifetime, CacheMissHandler. Use when caching data, optimizing queries, or working with session.caches.
Serverpod CLI — serverpod create, generate, create-migration, and other commands. Use when generating code, creating migrations, or creating projects/modules.
Configure Serverpod — YAML config, environment variables, passwords, run modes, generator.yaml, TLS. Use when setting up environments, API/database/Redis settings, or managing secrets.
Serverpod ORM with PostgreSQL — CRUD, filters, sorting, pagination, relations, migrations, transactions, raw SQL. Use when querying the database, writing migrations, or working with relations. Also include serverpod-models skill if you need to change models.
Define Serverpod endpoints, use Session, pass parameters, and call from client. Use when creating RPC endpoints, working with Session, or client code generation.

A Session provides access to database, cache, storage, messages, passwords, and logging. The framework creates and closes sessions automatically; only InternalSession requires manual management.
| Type | Created for | Lifetime |
|---|---|---|
| MethodCallSession | Endpoint methods | Single request |
| WebCallSession | Web server routes | Single request |
| MethodStreamSession | Stream methods | Stream duration |
| StreamingSession | WebSocket connections | Connection duration |
| FutureCallSession | Future calls | Task execution |
| InternalSession | Manual creation | Until closed |
Always close in a finally block:
var session = await Serverpod.instance.createSession();
try {
await doWork(session);
} finally {
await session.close();
}
Unclosed sessions leak memory and never persist logs. Using a closed session throws StateError.
session.addWillCloseListener((session) async {
// Runs just before session closes (all session types)
});
Sessions close when the endpoint returns. Do not capture for later use:
// BAD — session already closed when callback runs
Timer(Duration(seconds: 5), () => user.updateLastSeen(session));
Fix: Use a future call (session.serverpod.futureCalls.callWithDelay(...)) or create a new InternalSession inside the callback.
