What probably matters to youSection of the release
Direct editor delivery requires an env var plus a relayed human conversation, otherwise skipped.
What
A follow-up message on a thread can be handed directly to an artifact editor sub-agent that is still working, instead of going back through the coordinator first. It requires the environment variable CLAUDE_CODE_EDITOR_CODELIVERY to be set to a truthy value and the session to be a relayed human conversation; otherwise the path is skipped entirely.
Details
Matching relies on the editor's acknowledgement carrying a follow-up URL, checked against the coordinator's record of which editors are live.
Carries messages for the races this opens up: the worker dying mid-flight, the page being deleted, the page being republished by someone else, and the follow-up being withdrawn or cancelled.
Usage
CLAUDE_CODE_EDITOR_CODELIVERY=1 claude
