Key Design Principles

Pure Orchestrator: Execute phases in sequence (Phase 1, 3 sequential; Phase 2 parallel)
Auto-Continue: All phases run autonomously without user intervention between phases
Subagent Lifecycle: Explicit lifecycle management with spawn_agent → wait → close_agent
Progressive Phase Loading: Phase docs are read on-demand when phase executes
Parallel Execution: Phase 2 launches N role agents concurrently
Role Path Loading: Subagent roles loaded via path reference in MANDATORY FIRST STEPS

Auto Mode

When --yes or -y: Auto-select recommended roles, skip all clarification questions, use default answers.

Execution Flow

Parameter Parsing:
   ├─ Extract --count N (default: 3, max: 9)
   ├─ Extract --style-skill package-name (optional, for ui-designer)
   └─ Validate style SKILL package exists

Phase 1: Interactive Framework Generation
   └─ Ref: phases/01-interactive-framework.md
      ├─ Sub-phases: Phase 0-5 (Context → Topic → Roles → Questions → Conflicts → Spec)
      ├─ Output: guidance-specification.md + workflow-session.json
      └─ Parse: selected_roles[], session_id

Phase 2: Parallel Role Analysis
   └─ Ref: phases/02-parallel-role-analysis.md
      ├─ Spawn N conceptual-planning-agent (concurrent execution)
      ├─ For each role: Execute framework-based analysis
      ├─ Optional: ui-designer appends --style-skill if provided
      ├─ Lifecycle: spawn_agent → batch wait → close_agent
      └─ Output: [role]/analysis*.md (one per role)

Phase 3: Synthesis Integration
   └─ Ref: phases/03-synthesis-integration.md
      ├─ Spawn cross-role analysis agent
      ├─ User interaction: Enhancement selection + clarifications
      ├─ Spawn parallel update agents (one per role)
      ├─ Lifecycle: spawn_agent → wait → close_agent for each agent
      └─ Output: synthesis-specification.md + updated analyses

Return:
   └─ Summary with session info and next steps

Phase Reference Documents (read on-demand when phase executes):

Phase	Document	Purpose
1	phases/01-interactive-framework.md	Interactive clarification generating confirmed guidance specification through role-based analysis
2	phases/02-parallel-role-analysis.md	Unified role-specific analysis generation with interactive context gathering and concurrent execution
3	phases/03-synthesis-integration.md	Cross-role synthesis integration with intelligent Q&A and targeted updates

Core Rules

Start Immediately: First action is parameter parsing
No Preliminary Analysis: Do not analyze topic before Phase 1 - artifacts handles all analysis
Parse Every Output: Extract selected_roles from workflow-session.json after Phase 1
Auto-Continue: Execute next pending phase automatically after previous completes
Track Progress: Phase execution state managed through workflow-session.json
⚠️ CRITICAL: DO NOT STOP: Continuous multi-phase workflow. After completing each phase, immediately proceed to next
Parallel Execution: Phase 2 spawns multiple agent tasks simultaneously for concurrent execution
Progressive Phase Loading: Read phase docs ONLY when that phase is about to execute
Explicit Lifecycle: Always close_agent after wait completes to free resources

Usage

workflow:brainstorm:auto-parallel "<topic>" [--count N] [--style-skill package-name]

Recommended Structured Format:

workflow:brainstorm:auto-parallel "GOAL: [objective] SCOPE: [boundaries] CONTEXT: [background]" [--count N] [--style-skill package-name]

Parameters:

topic (required): Topic or challenge description (structured format recommended)
--count N (optional): Number of roles to select (default: 3, max: 9)
--style-skill package-name (optional): Style SKILL package to load for ui-designer (located at .codex/skills/style-{package-name}/)

Data Flow

Phase 0 → Phase 1

Input:

topic: User-provided topic or challenge description
count: Number of roles to select (parsed from --count parameter)
style_skill_package: Style SKILL package name (parsed from --style-skill parameter)

Output: None (in-memory variables)

Phase 1 → Phase 2

Input: topic, count, style_skill_package

Output:

session_id: Workflow session identifier (WFS-{topic-slug})
selected_roles[]: Array of selected role names
guidance-specification.md: Framework content
workflow-session.json: Session metadata

Parsing:

// Read workflow-session.json after Phase 1
const session_data = Read("${projectRoot}/.workflow/active/WFS-{topic}/workflow-session.json");
const selected_roles = session_data.selected_roles;
const session_id = session_data.session_id;
const style_skill_package = session_data.style_skill_package || null;

Phase 2 → Phase 3

Input: session_id, selected_roles[], style_skill_package

Output:

[role]/analysis*.md: One analysis per selected role
.superdesign/design_iterations/: UI design artifacts (if --style-skill provided)

Validation:

// Verify all role analyses created
for (const role of selected_roles) {
  const analysis_path = `${brainstorm_dir}/${role}/analysis.md`;
  if (!exists(analysis_path)) {
    ERROR: `Missing analysis for ${role}`;
  }
}

Phase 3 → Completion

Input: session_id, all role analyses, guidance-specification.md

Output:

synthesis-specification.md: Integrated cross-role analysis
Updated [role]/analysis*.md with clarifications

Validation:

const synthesis_path = `${brainstorm_dir}/synthesis-specification.md`;
if (!exists(synthesis_path)) {
  ERROR: "Synthesis generation failed";
}

Subagent API Reference

spawn_agent

Create a new subagent with task assignment.

const agentId = spawn_agent({
  message: `
## TASK ASSIGNMENT

### MANDATORY FIRST STEPS (Agent Execute)
1. **Read role definition**: ~/.codex/agents/{agent-type}.md (MUST read first)
2. Read: ${projectRoot}/.workflow/project-tech.json
3. Read: ${projectRoot}/.workflow/project-guidelines.json

---

## TASK CONTEXT
${taskContext}

## DELIVERABLES
${deliverables}
`
})

wait

Get results from subagent (only way to retrieve results).

const result = wait({
  ids: [agentId],
  timeout_ms: 600000  // 10 minutes
})

if (result.timed_out) {
  // Handle timeout - can continue waiting or send_input to prompt completion
}

// Check completion status
if (result.status[agentId].completed) {
  const output = result.status[agentId].completed;
}

send_input

Continue interaction with active subagent (for clarification or follow-up).

send_input({
  id: agentId,
  message: `
## CLARIFICATION ANSWERS
${answers}

## NEXT STEP
Continue with analysis generation.
`
})

close_agent

Clean up subagent resources (irreversible).

close_agent({ id: agentId })

Session Management

⚡ FIRST ACTION: Check {projectRoot}/.workflow/active/ for existing sessions before Phase 1

Multiple Sessions Support:

Different Codex instances can have different brainstorming sessions
If multiple sessions found, prompt user to select
If single session found, use it
If no session exists, create WFS-[topic-slug]

Session Continuity:

MUST use selected session for all phases
Each role's context stored in session directory
Session isolation: Each session maintains independent state

Output Structure

Phase 1 Output:

{projectRoot}/.workflow/active/WFS-{topic}/.brainstorming/guidance-specification.md (framework content)
{projectRoot}/.workflow/active/WFS-{topic}/workflow-session.json (metadata: selected_roles[], topic, timestamps, style_skill_package)

Phase 2 Output:

{projectRoot}/.workflow/active/WFS-{topic}/.brainstorming/{role}/analysis.md (one per role)
.superdesign/design_iterations/ (ui-designer artifacts, if --style-skill provided)

Phase 3 Output:

{projectRoot}/.workflow/active/WFS-{topic}/.brainstorming/synthesis-specification.md (integrated analysis)
Updated [role]/analysis*.md with Enhancements + Clarifications sections

⚠️ Storage Separation: Guidance content in .md files, metadata in .json (no duplication) ⚠️ Style References: When --style-skill provided, workflow-session.json stores style_skill_package name, ui-designer loads from .codex/skills/style-{package-name}/

Available Roles

data-architect (数据架构师)
product-manager (产品经理)
product-owner (产品负责人)
scrum-master (敏捷教练)
subject-matter-expert (领域专家)
system-architect (系统架构师)
test-strategist (测试策略师)
ui-designer (UI 设计师)
ux-expert (UX 专家)

Role Selection: Handled by Phase 1 (artifacts) - intelligent recommendation + user selection

Error Handling

Role selection failure: Phase 1 defaults to product-manager with explanation
Agent execution failure: Agent-specific retry with minimal dependencies
Template loading issues: Agent handles graceful degradation
Synthesis conflicts: Phase 3 highlights disagreements without resolution
Context overflow protection: Per-role limits enforced by conceptual-planning-agent
Agent lifecycle errors: Ensure close_agent in error paths to prevent resource leaks
