What
When you resume a session, Claude Code no longer silently re-enables automatic replies to comments on published Artifacts. It re-arms only what it can, and prints a reason for each one it skipped: you stopped watching it last time, this account cannot publish to that Artifact, another session may already be replying, it could not confirm no other session is replying, or you are already watching the cap of 5 Artifacts at once.
Details
- At most the most recent Artifact's comment monitor comes back on resume; a summary line names up to two Artifacts that were left unwatched.
- The skip reasons are internal codes with one sentence each:
recorded_stop,not_editor,holder_unknown,held_by_background,watch_capandwatch_cap_reconnect. - The watch limit of 5 comes from a constant interpolated into the message, so the sentence always matches the real cap.
- Re-arming calls are marked as resumes, and an Artifact recorded as armed carries forward the consent to publish replies, so you are not asked again.
Evidence
a resumed session brings back at most its most recent Artifact's comment monitor
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
