Architecture

How services connect from chat to sandbox validation.

pnpm health

Gateway orchestrates chat (AI SDK stream) and async workflow jobs
Agent service runs LangGraph Discovery → Planning → Edit → Review
Notification service streams SSE progress by jobId
Execution service provisions sandboxes for validation runs
Validation service runs lint / test / build as structured results

Concepts

Mode B (hybrid) streaming

The default for full app builds—conversation and long-running jobs on separate channels.

Chat

AI SDK stream + tool UI

Job

Async workflow by jobId

SSE

Progress + node events

Sandbox

CubeSandbox execution

Validation

Lint / test / build

Keep the chat channel for conversation and tool UI, and open the progress channel for sandbox + validation events. Long jobs should not pin a single HTTP stream open for minutes—async workflows resume via jobId and SSE when you reconnect.
