Continues the Studio Web effort that landed the web-server + web connector (#3816) and the
AgentRuntimeseam.How AI was used in this PR
The runtime, the SSE reader, the pause/answer/resume handling, and this description were drafted with Claude Code, then reviewed; the change typechecks and builds locally.
Proposed Changes
Studio Web can now run the agent in a hosted SecEx sandbox instead of a local child process, so the browser build of Studio works without anything running on the user's machine. Each user gets one sandbox — the cloud analog of "your laptop", with the same
~/Studio/sites and~/.claudesessions inside it, like the desktop app.It plugs into the existing
AgentRuntimeseam: a new runtime drives the wpcomstudio-codeendpoint (POST /wpcom/v2/studio-code/run), which runsstudio code --jsonin the sandbox and streams its events back over SSE. The web-server relays those through the same callbacks the local runtime already uses, so the run-manager and the browser UI are untouched.Interactive questions and multi-turn work like the desktop. There's no live process in the sandbox to answer over IPC, so the runtime mirrors the proven headless pattern: when a turn pauses on a question the agent process stays "connected" instead of exiting, and answering re-drives the endpoint with the user's choice as the next message on the same sandbox session (resolved from
turn.completed.sessionId). To the web-server and the UI it looks like an ordinary live run that asks and gets answered.It's opt-in and zero-risk by default: the local child-process backend stays the default, and the SecEx runtime is only installed when
STUDIO_WEB_BACKEND=secexis set.Testing Instructions
Without the env var,
web-serverbehaves exactly as before (local agent).Pre-merge Checklist
