Brake

/pitwall:brake

Stop now and save the unfinished work as a WIP commit.

What it does

/pitwall:brake stops the loop now. It cancels the next round first, then saves the unfinished task as a WIP commit on its branch (a stash if a hook refuses the commit), and switches back to the base. Nothing is discarded and no PR is opened. Nothing is pushed either, unless the profile hands work between machines; then the WIP branch is pushed so the other machine can resume it.

Use it when

you need the checkout back immediately
a round is going somewhere you do not want

To let the current task finish first, use /pitwall:stop.

Try it

/pitwall:brake

What you’ll see

The example comes from a made-up repo, acme/shop.

Stopped P2-05 Pay with a saved card
  step    coding
  branch  agent/p2-05-saved-card
  saved   commit "wip: P2-05 stopped at coding"
Done      P2-04 #58 PARTIAL
Parked    none
Continue  /pitwall:drive resumes P2-05 from this step

With a tracker, the task gets a comment saying where it stopped and how the work was saved; its status stays in progress.

Resume

Run /pitwall:drive. The first round picks the stopped task up at the step it left, on the same branch.

The playbook the agent followsThe full spec for /pitwall:brake. This page sums it up; when the two differ, the playbook wins.

/pitwall:brake — stop immediately, save unfinished work

ScheduleWakeup stop:true before anything else (prevents the next round from firing on top)
Read state (path in .claude/agent-loop.md; no file + the profile has a “multi-machine” section → receive first) — none / running:false → say “not running” (in the profile’s user language), end
Set running:false, stopRequested:true and write it back (keep currentTask / branch / step so /pitwall:drive can resume)
Has currentTask:
- cancel subagents that are still running
- git status --porcelain has changes → git add -A && git commit -m "wip: <id> stopped at <step>" on the current branch — hook fails → git stash push -u -m "agent-loop <id> @<step>" and record stash in state · don’t open a PR, never discard · don’t push — unless the profile has a “multi-machine” section: push the WIP branch and record stashMachine per that section
- git switch <base>
- has trackerId → comment (in the profile’s tracker language) starting with **[Claude] Stopped by /pitwall:brake**: the step it stopped at, branch, saved as commit or stash — status stays in progress
multi-machine → send state
Report (in the profile’s user language): the unfinished task + branch + the step it stopped at + how it was saved, summary of done / parked, how to continue (/pitwall:drive resumes on its own)
