Cancel Ship

To cancel the ship pipeline:

1. Check if .claude/ucai-ship.local.md exists using Bash: test -f .claude/ucai-ship.local.md && echo "EXISTS" || echo "NOT_FOUND"

2. If NOT_FOUND: Say "No active ship pipeline found."

3. If EXISTS:

   • Read .claude/ucai-ship.local.md to get the current phase, milestone, and any worktree/branch info
   • Remove the file using Bash: rm .claude/ucai-ship.local.md
   • Report: "Cancelled ship pipeline (was at Phase N: PhaseName, milestone: M)"

4. Cleanup warnings (check each, report what applies):

   • Run git worktree list — if a ship worktree exists, warn: "Ship worktree still exists at [path]. Run git worktree remove [path] to clean up, or inspect it first."
   • If the state file mentioned a branch that was pushed, warn: "Remote branch [name] may still exist. Run git push origin --delete [name] if you want to remove it."
   • If a PR was created, warn: "A PR may have been created. Check your GitHub repo and close it if no longer needed."

5. Do NOT auto-delete worktrees, branches, or PRs — the user decides what to keep.
