SDK
Domain: Gateway & Platforms
Motivation
The SDK profile is for programmatic use: dsh --profile sdk serves SDK clients over JSON-RPC stdio until shutdown or disconnect. It is a profile, not a separate public bin, and the TypeScript dsh-sdk-client and the Python SDK are the wire clients. Choose it when your code needs to open sessions and drive harness agents out of process.
Concrete Example
dsh --profile sdk --help writes help and exits without claiming stdin or stdout, because the app-owned command provider accepts the invocation first.
Analogy
A factory’s external API port: machines outside the building can place and track orders.
