Bmad Planner

BMAD Planner

Purpose

Business Model, Architecture, and Design documentation created in main repository before feature development begins.

Now available as an interactive callable Python script - saves ~2,000-2,700 tokens per feature compared to manual reproduction.

When to Use

• Current directory: main repository (not worktree)
• Current branch: contrib/<gh-user>
• Phase: Planning (Phase 1)

Interactive Callable Tool

BMAD is now an interactive callable tool that runs as a Python script in the main repository.

======================================================================
✓ BMAD Planning Documents Created Successfully!
======================================================================

Files created in planning/my-feature:
  - requirements.md (Business requirements and acceptance criteria)
  - architecture.md (Technical architecture and design)
  - epics.md (Epic breakdown and planning)
  - CLAUDE.md (Context for Claude Code)
  - README.md (Human-readable overview)
  - ARCHIVED/ (Directory for deprecated planning docs)

Next steps:
  1. Review planning documents in planning/my-feature
  2. Create feature worktree
  3. SpecKit will auto-detect and use these planning documents
  4. Token savings: ~1,700-2,700 tokens by reusing planning context

What happens:

1. Script validates location (main repo, contrib branch)
2. Conducts 🧠 Analyst Q&A (5-10 questions)
3. Generates requirements.md from template + Q&A responses
4. Conducts 🏗️ Architect Q&A (5-8 questions)
5. Generates architecture.md from template + Q&A responses
6. Automatically analyzes requirements + architecture (📋 PM)
7. Generates epics.md with epic breakdown
8. Creates compliant planning// directory structure
9. Commits changes to contrib branch

Interactive Planning Approach

BMAD uses a three-persona method to gather comprehensive planning information through interactive Q&A sessions with the user.

🧠 Persona 1: BMAD Analyst (Requirements)

Role: Business Analyst creating Product Requirements Document

Process:

1. Ask user about problem statement and business context
2. Identify target users and stakeholders
3. Define success criteria and measurable outcomes
4. Gather functional and non-functional requirements
5. Document user stories with scenarios
6. Identify risks and constraints

Interactive Q&A Example:

I'll help create the requirements document using the BMAD Analyst persona.

What problem does this feature solve?
> [User describes the problem]

Who are the primary users of this feature?
> [User identifies user types]

How will we measure success for this feature?
> [User defines success metrics]

What are the must-have capabilities? (functional requirements)
> [User lists key capabilities]

Any performance, security, or scalability requirements? (non-functional)
> [User specifies NFRs]

Generates: planning/<feature>/requirements.md using comprehensive template

🏗️ Persona 2: BMAD Architect (Architecture)

Role: Technical Architect designing system architecture

Process:

1. Read requirements.md for business context
2. Ask user about technology preferences and constraints
3. Design system components and data models
4. Define API contracts and integration points
5. Specify security, error handling, testing strategies
6. Document deployment and observability approach

Interactive Q&A Example:

Based on the requirements, I'll design the technical architecture.

Technology preferences?
- Web framework: FastAPI / Flask / Django?
> [User chooses framework]

Database requirements?
- Development: SQLite
- Production: PostgreSQL / MySQL?
> [User chooses database]

Performance targets?
- Response time: < 200ms?
- Concurrent users: How many?
> [User specifies targets]

Container strategy?
- Using Podman (default for this project)
- Multi-container setup needed?
> [User confirms approach]

Generates: planning/<feature>/architecture.md using comprehensive template

📋 Persona 3: BMAD PM (Epic Breakdown)

Role: Project Manager breaking down work into epics

Process:

1. Read requirements.md + architecture.md for full context
2. Identify major work streams (epics)
3. Define scope, complexity, and dependencies for each epic
4. Prioritize epics (P0/P1/P2)
5. Create implementation timeline
6. Estimate effort and identify risks

Analysis:

Analyzing requirements and architecture to create epic breakdown...

Identified 3 major epics:
1. E-001: Data Layer (Foundation) - P0, High complexity
2. E-002: API Layer (Core functionality) - P0, Medium complexity
3. E-003: Testing & Quality - P1, Medium complexity

Dependencies detected:
  E-001 → E-002 (API needs data layer)
  E-002 → E-003 (tests need API)

Creating epic breakdown document...

Generates: planning/<feature>/epics.md with epic definitions, priorities, timeline

How to Invoke BMAD

When workflow-orchestrator loads bmad-planner during Phase 1, it calls the create_planning.py script.

Workflow Orchestrator Code:

# In workflow orchestrator - Phase 1.1
if current_phase == 1 and current_step == '1.1':
    import subprocess

    result = subprocess.run([
        'python',
        '.claude/skills/bmad-planner/scripts/create_planning.py',
        slug,       # my-feature
        gh_user,    # stharrold
    ], check=True)

    # Script handles:
    # - 🧠 Analyst Q&A with user
    # - 🏗️ Architect Q&A with user
    # - 📋 PM epic breakdown (automatic)
    # - requirements.md, architecture.md, epics.md generation
    # - Directory structure creation
    # - Git commit

    print(f"✓ BMAD planning created in planning/{slug}/")
    print("  Next: Create feature worktree (Phase 2)")

User Experience:

Phase 1: BMAD Planning Session

Workflow calls:
  python .claude/skills/bmad-planner/scripts/create_planning.py my-feature stharrold

Script conducts interactive session:
  🧠 BMAD Analyst: Requirements gathering [5-10 questions]
  🏗️ BMAD Architect: Architecture design [5-8 questions]
  📋 BMAD PM: Epic breakdown [automatic analysis]

✓ Generated: planning/my-feature/requirements.md
✓ Generated: planning/my-feature/architecture.md
✓ Generated: planning/my-feature/epics.md
✓ Committed to contrib branch

✓ BMAD planning complete!
  Next: Create feature worktree (Phase 2 will use these docs)
  Token savings: ~2,300 tokens vs manual approach

Integration with Workflow

The workflow-orchestrator calls the create_planning.py script during Phase 1:

# In workflow orchestrator
if current_phase == 1 and current_step == '1.1':
    import subprocess

    result = subprocess.run([
        'python',
        '.claude/skills/bmad-planner/scripts/create_planning.py',
        slug,
        gh_user,
    ], check=True)

    print(f"✓ BMAD planning created: planning/{slug}/")

Output Files

BMAD generates three planning documents that become input context for SpecKit:

planning/<feature-name>/
├── requirements.md    # Business requirements (170 lines from template)
│   ├─ Problem statement, stakeholders
│   ├─ Functional requirements (FR-001, FR-002...)
│   ├─ Non-functional requirements (performance, security...)
│   ├─ User stories with scenarios
│   └─ Risks, assumptions, success criteria
│
├── architecture.md    # Technical architecture (418 lines from template)
│   ├─ System overview, components
│   ├─ Technology stack with justifications
│   ├─ Data models, API endpoints
│   ├─ Container architecture (Containerfile, podman-compose.yml)
│   ├─ Security, error handling, testing strategies
│   └─ Deployment, observability, disaster recovery
│
├── epics.md          # Epic breakdown (245 lines from template)
│   ├─ Epic definitions (scope, complexity, priority)
│   ├─ Dependencies and critical path
│   ├─ Implementation timeline
│   └─ Resource requirements and risks
│
├── CLAUDE.md         # Context for this planning directory
├── README.md         # Human-readable overview
└── ARCHIVED/         # Deprecated planning documents

These files become input context for SpecKit in Phase 2.

Integration with SpecKit

BMAD documents are used as context when creating SpecKit specifications:

Data Flow: BMAD → SpecKit

Phase 1 (Main Repo, contrib branch):

BMAD Interactive Session
  ↓
planning/<feature>/
├── requirements.md
├── architecture.md
└── epics.md

Create Worktree:

# Worktree creation preserves link to main repo
git worktree add ../repo_feature_<slug> feature/<timestamp>_<slug>

Phase 2 (Worktree):

SpecKit reads from main repo:
../planning/<feature>/requirements.md → Business context
../planning/<feature>/architecture.md → Technical design
../planning/<feature>/epics.md        → Epic priorities

SpecKit generates (informed by BMAD):
specs/<feature>/spec.md  ← Detailed specification
specs/<feature>/plan.md  ← Implementation tasks

Why This Connection Matters

Consistency:

• Technology choices in spec.md match architecture.md stack
• spec.md acceptance criteria cover requirements.md success criteria
• plan.md tasks align with epics.md breakdown

Completeness:

• All functional requirements from requirements.md appear in spec.md
• Non-functional requirements (performance, security) included
• Epic dependencies reflected in plan.md task ordering

Traceability:

• spec.md sections reference FR-001, FR-002... from requirements.md
• plan.md tasks map to E-001, E-002... from epics.md
• Architecture decisions from architecture.md justify implementation choices

Less Rework:

• Planning clarifies requirements before coding
• Design decisions made explicit
• Reduces ambiguity and prevents scope creep

Integration with Workflow

The workflow-orchestrator calls this skill during Phase 1:

# In workflow orchestrator
if current_phase == 1 and current_step == '1.1':
    load_skill('bmad-planner')
    create_planning_docs(feature_name, gh_user)
    commit_changes('docs: add BMAD planning for ' + feature_name)

Template Placeholders

Both templates use these placeholders:

• {{TITLE}} - Feature name (title case)
• {{DATE}} - Creation date (YYYY-MM-DD)
• {{GH_USER}} - GitHub username

Best Practices

• Requirements first: Define business needs before technical design
• Acceptance criteria: Make success measurable
• Architecture clarity: Explain design decisions and trade-offs
• Technology justification: Document why specific tools/frameworks chosen
• Non-functional requirements: Don't forget performance, security, scalability
