Typing `!git status` in a session's composer now runs the command in the session's working copy (the worktree when it has one) instead of sending it to the model, like Claude Code's bash mode. The command, its stdout, stderr and exit code show as a card of their own in the transcript, are saved with the session, and go to the agent with the next message in Claude Code's <bash-input> / <bash-stdout> / <bash-stderr> tags. The command runs through the shell the terminal opens, with the environment and process group a harness gets. While it runs the session is busy, so Stop and Escape end it and messages sent meanwhile queue until it is done. Each stream keeps its first 30,000 bytes. Remote projects are left as they were: the host has no way to run an arbitrary command yet, so there `!` stays an ordinary message. Closes hardbeat920#968

Explanation
Issue
#968requires leading!commands for local and remote SSH workspaces. The PR implements local execution, including session-directory handling, shell execution, output capture, stop behavior, transcript persistence, agent context, and focused tests. The PR explicitly leaves remote sessions unchanged because no remote execution capability exists. This leaves a concrete coding requirement unmet.Resolution
Add a remote execution capability to the host protocol. Route leading
!commands from remote sessions through that capability. Implement remote working-directory and environment handling, output capture, exit status, persistence, agent context, stop behavior, and tests.

sessions for which shellCommandRunning(session) is true, so active shell
commands are not persisted as interrupted agent turns. Leave isInFlightSession

Quitting while a `!` command runs left the session busy, so inFlightRefs listed it, the quit wrote "Turn interrupted when MonoCode quit." and the next launch sent the agent "Continue from where you left off." though no agent turn was cut short. The quit dialog still counts it as running.

Block shell commands while automatic continuation is pending.
A restored interrupted session has busy: false and the interrupt message as its last block. The composer can submit ! before the delayed continuation callback runs. onRunShellCommand then appends a running shell block and sets busy: true.
If the user quits while that command runs, inFlightRefs excludes the session. The quit path therefore does not persist a relaunch reference. The shell block also hides the interrupt message, so the session no longer qualifies for automatic continuation after relaunch. Guard the shell entrypoint while canAutoContinue(current) is true.
Suggested fix
if (!current || current.worktreeRemoved || remoteProjectFor(current.cwd))
return false;

The cherry-picked upstream PR hardbeat920#1042 writes its card and its busy notice in English; they go through i18n here (sessions:shellCommand.*, app:shellCommand.busy). Up / Down in the composer now steps through the `!` commands too, written the way they were typed, and stopping a running command with Escape no longer hands an earlier message back to the composer.

What changed
Typing
!git status(or!npm test, …) in a session's composer runs the command in the session's working copy instead of sending it to the model, like Claude Code's bash mode. The command, its stdout / stderr and exit code show as a card in the transcript, are saved with the session, and go to the agent with the next message. Closes #968.Why
#968: running a quick command meant leaving the conversation for a terminal, and the agent never saw what you ran.

The output scrolls past 20rem.sanitizeBlockkeeps it. A command that a quit cut short restores as Stopped.activeTurnIndextreats a trailing command as "no live turn", so the agent's previous turn doesn't light up as Working while the command runs.Busy while it runs — the session is
busy, so:onStop, which only signals the command and leaves the agent's process alone.!typed during an agent turn is refused with a status line.Context for the agent —
submitSessionprefixes the next prompt with every command run since the last message, using Claude Code's tags and adding the exit code (withShellCommands):This happens before the handoff wrap, so it works the same for Claude, Codex and every other harness. Native slash commands and edited resends don't get it.
