mcp.exec.RunOutcome.NoShell

Description#

The keys were sent but the opening sentinel never came back. That is what a pane looks like when it is not at a shell prompt: sitting in an editor or a REPL, or still running something an earlier call left behind. The text was typed into whatever is there.

The evidence is absence, so a deadline too short for the pane's shell to have echoed anything yet looks the same. Read it as "nothing came back in the time allowed" and check the pane with snapshot_pane before concluding it is stuck.
