# Brainstorm Skill

Unified brainstorming skill combining interactive framework generation, multi-role parallel analysis, and cross-role synthesis into a single entry point with two operational modes.

## Key Features

- **Dual-Mode Operation**: Auto mode (full pipeline) and single role mode (individual analysis)
- **Interactive Framework Generation**: Seven-phase workflow for guidance specification
- **Parallel Role Analysis**: Concurrent execution of multiple role perspectives
- **Cross-Role Synthesis**: Integration of insights into feature specifications
- **SPEC.md Quality Standards**: Guidance specification includes Concepts & Terminology, Non-Goals, RFC 2119 constraints
- **Template-Driven Role Analysis**: system-architect produces Data Model, State Machine, Error Handling, Observability, Configuration Model, Boundary Scenarios
- **Automated Quality Gates**: Validation agents ensure outputs meet quality standards
- **Session Continuity**: All phases share state via workflow-session.json
- **Progressive Loading**: Phase documents loaded on-demand via Ref markers

### Execution Flow

**Auto Mode**:
1. **Phase 1**: Mode detection and parameter parsing
2. **Phase 1.5**: Terminology & Boundary Definition (extract terms, collect Non-Goals)
3. **Phase 2**: Interactive Framework Generation (7 sub-phases)
   - Context collection → Topic analysis → Role selection → Role questions → Conflict resolution → Final check → Generate specification
   - **Phase 5**: Generate guidance-specification.md with Concepts & Terminology, Non-Goals, RFC 2119 constraints
4. **Phase 3**: Parallel Role Analysis (N concurrent role analyses)
   - Template-driven analysis with quality validation
   - system-architect includes: Data Model, State Machine, Error Handling, Observability, Configuration Model, Boundary Scenarios
5. **Phase 4**: Synthesis Integration (6 sub-phases)
   - Discovery → File discovery → Cross-role analysis → User interaction → Spec generation → Finalization

**Single Role Mode**:
1. **Phase 1**: Mode detection and parameter parsing
2. **Phase 3**: Single role analysis (4 sub-phases)
   - Detection → Context → Agent → Validation

## Usage

### Auto Mode

```bash
# Full pipeline with default settings
/brainstorm "Build real-time collaboration platform"

# Auto-select mode with specific role count
/brainstorm -y "GOAL: Build platform SCOPE: 100 users" --count 5

# With style skill for UI designer
/brainstorm "Design payment system" --style-skill material-design
```

### Single Role Mode

```bash
# Analyze with specific role
/brainstorm system-architect --session WFS-xxx

# With interactive questions
/brainstorm ux-expert --include-questions

# Update existing analysis
/brainstorm ui-designer --session WFS-xxx --update --style-skill material-design

# Skip questions (use defaults)
/brainstorm product-manager --skip-questions
```

## Quality Standards

### Guidance Specification
- **Section 2**: Concepts & Terminology (5-10 core terms with definitions, aliases, categories)
- **Section 3**: Non-Goals (Out of Scope) with rationale
- **RFC 2119 Keywords**: All requirements use MUST, SHOULD, MAY

### Role Analysis (system-architect)
1. **Architecture Overview**: High-level system design
2. **Data Model**: 3-5 core entities with precise field definitions
3. **State Machine**: Lifecycle for 1-2 entities with complex workflows
4. **Error Handling Strategy**: Global + per-component recovery
5. **Observability Requirements**: Metrics, logs, health checks
6. **Configuration Model**: All configurable parameters with validation
7. **Boundary Scenarios**: Concurrency, rate limiting, shutdown, cleanup, scalability, DR

### Quality Validation
- Template compliance checking
- RFC 2119 keyword usage verification
- Diagram syntax validation
- Section completeness scoring
