Commenting on an artifact in the desktop app can now launch a Claude Code session from that comment.

What

The desktop app can hand the CLI a prompt built from a comment you left on an artifact, and the CLI now recognises that handoff, picks up the comment thread it refers to, and marks the prompt so its own comment watcher does not reply to the same comment a second time. This path is desktop-app only; other clients never see it.

Details
  • The seeded prompt is identified by a first line of [Artifact comment sent to Claude], followed by Artifact: , Comment thread: and Sent to Claude at: lines, which the CLI parses to claim the thread.
  • The message flag is seeded_summon in the SDK message schema, documented as @internal Desktop host only: the host's own seeded summon.
  • Gated on the client identifying itself as the desktop host (client platform desktop_app). None of this existed in the previous release.
Evidence

[Artifact comment sent to Claude]

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
