notes
The Claude Agent SDK runtime is a thin Node/Python library — there is
no separate runtime daemon. Tools are supplied by the consumer; MCP
is brokered by the SDK over stdio and streamable-http. Approval
gating, transcript persistence, and subprocess sandboxing are all
delegated back to the host program.
