Built-in Services
The current Downcity runtime registry includes five built-in services:

This page is the entry point. The actual service-by-service documentation now lives in a dedicated built-ins section, similar to built-in plugins.
Where to go next
Two layers to keep separate
Runtime built-ins
These are the services already registered by the full Downcity runtime.
Explicit SDK assembly
This is the subset of service behavior that an @downcity/agent user can intentionally assemble into a local Agent.
Those two layers overlap, but they are not identical.
Today, the most direct explicit SDK path is still:
ChatServiceBaseServicefor custom services
The new built-ins pages document the whole runtime set from an SDK point of view, including the services that are more runtime-shaped than constructor-first.
