resume-nudge

When a session reopens after a restart or crash cut a turn off, this drafts the standard pick-up prompt in the prompt box: "The Mac restarted and this session was interrupted. Pick up exactly where you left off…". Press Enter to send it, or ignore it.

It treats the session as cut off when the last message is one of:

• a tool call that never returned,
• a tool result Claude never answered,
• a prompt Claude never answered.

It is not cut off when the turn ended with an answer, or when you pressed Esc ([Request interrupted by user]).

• /resume-here sends the pick-up prompt, only when the session is cut off. Use it from the phone, where the drafted text may not show.
• /resume-here check reports the verdict and never sends.

It never sends on its own. session.start does not fire after an in-session /resume; use /resume-here there.

Hooks: session.start, command.run. Calls: $.session.messages, $.prompt.fill, $.prompt.submit (only from /resume-here, on a timer once the command has answered), $.ui.toast, $.command.register.

Test: claude plugin test . (4 tests).
