bail

Bail-out protocol: always reflect FIRST, then clean up. All commands use absolute paths and git -C.

Inputs

• WORKTREE: absolute path to current worktree (or primary if no worktree)
• Optional reason string (if not provided, ask for one)

Steps

1. Detect current step by examining what exists:

   What exists	Estimated step
   Just an issue, no branch	Step 0 (Capture)
   .branch-context.md, no worktree	Step 1 (Orient)
   Worktree exists, no code changes	Step 2 (Isolate)
   Plan file on branch	Step 3-4 (Design/Review)
   Code changes committed	Step 5-7 (Build/Verify/Archive)
   PR open on GitHub	Step 8 (Ship)

2. Prompt for reason if not provided.

3. Write learnings to .branch-context.md in the worktree:

   # Write bail context — use absolute path
   cat >> "$WORKTREE/.branch-context.md" <<EOF
   
   ## Bail
   - Reason: <reason>
   - What was attempted: <summary>
   - What was learned: <learnings>
   EOF
   git -C "$WORKTREE" add .branch-context.md
   git -C "$WORKTREE" commit -m "docs: capture bail context"
   

4. Consolidate learnings to MEMORY.md via disposable clone (never checkout main in a worktree):

   BAIL_DIR="${CLAUDE_SESSION_DIR:-$TMPDIR}/bail-reflect"
   [ -d "$BAIL_DIR" ] && rm -rf "$BAIL_DIR"
   git clone --depth 50 "$(git -C "$WORKTREE" remote get-url origin)" "$BAIL_DIR"
   

   Read $BAIL_DIR/ai-workspace/MEMORY.md, append relevant learnings from .branch-context.md, then:

   git -C "$BAIL_DIR" add ai-workspace/MEMORY.md
   git -C "$BAIL_DIR" commit -m "docs: consolidate learnings from abandoned <branch>
   
   Co-Authored-By: Claude <model>"
   git -C "$BAIL_DIR" push
   

   On non-fast-forward: git -C "$BAIL_DIR" pull --rebase then push. Max 3 retries. Clean up: rm -rf "$BAIL_DIR"

5. Update GitHub Issue (if accessible):

   GH_REPO=<owner/repo> gh issue comment <number> --body "Bailing: <reason>. Learnings captured in MEMORY.md."
   GH_REPO=<owner/repo> gh issue edit <number> --add-label "deferred" --remove-label "triage"
   

6. Close PR if open:

   PR_NUM=$(GH_REPO=<owner/repo> gh pr list --head "<branch>" --json number -q '.[0].number')
   if [ -n "$PR_NUM" ]; then
     GH_REPO=<owner/repo> gh pr close "$PR_NUM"
   fi
   

7. Ask about branch preservation:

   Default: preserve the branch (user can resume later).

   If user explicitly says delete — confirm by showing what will be destroyed:

   This will delete:
   - Branch: <name>
   - Worktree: <path>
   - Remote branch (if pushed)
   
   Type 'delete' to confirm.
   

   Only after typed confirmation:

   PRIMARY="$(git -C "$WORKTREE" worktree list --porcelain | grep -m1 '^worktree ' | sed 's/^worktree //')"
   # Verify branch is merged before deleting (-d fails if unmerged, -D would force)
   git -C "$PRIMARY" worktree remove "$WORKTREE"
   git -C "$PRIMARY" branch -d <branch>
   

   If branch -d fails (unmerged work), warn the user and stop. Do NOT use branch -D.

8. Done. Do not checkout main — stay in whatever CWD the session has.

Edge Cases

• No worktree exists (bailing at Step 0-1) → skip worktree cleanup, just update issue
• No GitHub access → skip issue update, still do local cleanup + memory consolidation
• PR already merged → don't close, just note it in the output
• No .branch-context.md → create one with just the bail reason before consolidating
• CLAUDE_SESSION_DIR unset → fall back to $TMPDIR for clone

Output: Summary of what was cleaned up and where learnings were saved.
