Bmad Story Pipeline Worktree

BMAD Story Pipeline (Worktree Edition)

Complete the delivery pipeline for story {ARGUMENT} using configurable workflow in an isolated git worktree, merge to main branch only after all tests pass.

Pre-step: Determine Story Number

If {ARGUMENT} is empty or not provided:

1. Read _bmad-output/implementation-artifacts/sprint-status.yaml (or docs/sprint/sprint-status.yaml) to find stories
2. Find the first story with status "todo" or "in-progress"
3. Use that story number as {STORY_ID}
4. If no story found, ask user to specify story number

The story number format is typically X-Y (e.g., 1-1, 2-3).

Set STORY_ID = {ARGUMENT} for all subsequent steps.

Difference from bmad-story-pipeline

Phase 1: Create Worktree

Do this yourself (not via Task agent):

1. Get current project name, path and branch:
   ORIGINAL_REPO_PATH=$(pwd)
   PROJECT_NAME=$(basename $(pwd))
   CURRENT_BRANCH=$(git branch --show-current)

2. Create new branch name: feature/story-${STORY_ID}

3. Create worktree directory (in sibling directory):
   WORKTREE_PATH="../${PROJECT_NAME}-story-${STORY_ID}"

4. Execute git worktree command:
   git worktree add -b feature/story-${STORY_ID} "$WORKTREE_PATH" $CURRENT_BRANCH

   If branch already exists, use:
   git worktree add "$WORKTREE_PATH" feature/story-${STORY_ID}

5. Verify worktree created:
   git worktree list

Variables saved for later phases:

• ORIGINAL_REPO_PATH - Original repository path (for merge step)
• WORKTREE_PATH - Worktree path
• STORY_ID - Story number

Progress output:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
✅ Create Worktree
   🌿 Branch: feature/story-${STORY_ID}
   📁 Path: ${WORKTREE_PATH}
   📦 Original: ${ORIGINAL_REPO_PATH}
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Phase 2: Run Configurable Pipeline

Switch to worktree directory first, then run the pipeline.

Read workflow steps from references/workflow-steps.md.

Execute each step sequentially using Task tool (general-purpose agent):

Task(
  subagent_type: "general-purpose",
  description: "<Step description>",
  prompt: "Execute the command: <COMMAND_WITH_STORY_ID>
Return: 1) Step completion status 2) Key outputs 3) Any issues to note"
)

Example Invocations

Step 1 - Create Story:

Task(
  subagent_type: "general-purpose",
  description: "Create user story {STORY_ID}",
  prompt: "Execute /bmad-bmm-create-story {STORY_ID} yolo to create story file. Return: 1) Story ID and Title 2) Created files 3) Any issues"
)

Step 2 - ATDD Tests:

Task(
  subagent_type: "general-purpose",
  description: "Generate ATDD tests for {STORY_ID}",
  prompt: "Execute /bmad-tea-testarch-atdd {STORY_ID} yolo to generate acceptance tests. Return: 1) ATDD checklist 2) Test files created 3) Any issues"
)

Step 3 - Development:

Task(
  subagent_type: "general-purpose",
  description: "Develop user story {STORY_ID}",
  prompt: "Execute /bmad-bmm-dev-story {STORY_ID} yolo to implement story code. Return: 1) Modified files 2) Summary of changes 3) Any issues"
)

Step 4 - Code Review:

Task(
  subagent_type: "general-purpose",
  description: "Code review for {STORY_ID}",
  prompt: "Execute /bmad-bmm-code-review {STORY_ID} yolo for adversarial review. Return: 1) Conclusion (pass/needs-fix) 2) Issues by severity 3) Any blocking issues"
)

Step 5 - Trace Coverage:

Task(
  subagent_type: "general-purpose",
  description: "Trace test coverage for {STORY_ID}",
  prompt: "Execute /bmad-tea-testarch-trace {STORY_ID} yolo for traceability matrix. Return: 1) Coverage percentage 2) Gate decision 3) Any gaps"
)

Execution Flow

For each step:

1. Replace {STORY_ID} with the actual story number in the prompt
2. Call Task tool with the step's description and prompt
3. Wait for completion and capture result
4. Output progress: [X/N] Step Name - Status
5. If step fails, stop and report error

Progress Display

After each step, output progress:

📊 Pipeline Progress: [X/N] ████████░░░░ 40%

✅ Step X: <Step Name>
   Result: <Brief result summary>

Phase 3: Update Status to Done

Before merge, update status in worktree (so changes are included in merge).

After ALL pipeline steps complete successfully:

1. Update sprint-status.yaml:

   • Find the story entry
   • Change status from in-progress to done

2. Update story document (if exists):

   • Change Status: to done
   • Mark all tasks with ✅

Progress output:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
✅ Update Status
   📝 sprint-status.yaml: ${STORY_ID} → done
   📄 Story doc: Status: done, Tasks: ✅
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Phase 4: Merge or Preserve

Critical decision step: Check merge conditions

Merge conditions:

1. All pipeline steps completed successfully
2. No HIGH/MEDIUM issues (or all fixed)
3. Tests pass

If all conditions are met, execute merge yourself:

1. Commit all changes in worktree (including status updates):
   cd ${WORKTREE_PATH}
   git add .
   git commit -m "feat: complete story ${STORY_ID}"

2. Switch back to main repo:
   cd ${ORIGINAL_REPO_PATH}

3. Merge feature branch:
   git merge feature/story-${STORY_ID} --no-edit

4. Remove worktree:
   git worktree remove ${WORKTREE_PATH}

5. Optionally delete feature branch (if not needed):
   git branch -d feature/story-${STORY_ID}

6. Verify cleanup:
   git worktree list

Progress output:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
✅ Merge Branch
   🔀 Merge: feature/story-${STORY_ID} → [current branch]
   🗑️ Cleanup: worktree removed
   📝 Commit: [hash]
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

If merge conditions not met, preserve worktree for manual handling:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
⚠️ Merge Branch
   ❌ Merge conditions not met, preserving worktree
   📁 Path: ${WORKTREE_PATH}
   🔧 Manual handling needed:
   - [List unmet conditions]

   After handling, manually execute:
   cd ${WORKTREE_PATH}
   git add . && git commit -m "fix: resolve issues"
   cd ${ORIGINAL_REPO_PATH}
   git merge feature/story-${STORY_ID}
   git worktree remove ${WORKTREE_PATH}
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Error Handling

If any step fails:

1. Stop executing subsequent steps
2. Preserve worktree (don't delete)
3. Output error information and current state
4. Prompt user how to manually fix
5. Provide recovery commands

Recovery command examples:

# List all worktrees
git worktree list

# Continue working in worktree
cd ${WORKTREE_PATH}

# Commit after manual completion
git add . && git commit -m "fix: manual fix"

# Switch back to main repo and merge
cd ${ORIGINAL_REPO_PATH}
git merge feature/story-${STORY_ID}

# Cleanup worktree
git worktree remove ${WORKTREE_PATH}

# Optional: delete feature branch
git branch -d feature/story-${STORY_ID}
