Brainstorm With File

Codex Brainstorm-With-File Prompt

Overview

Interactive brainstorming workflow with documented thought evolution. Expands initial ideas through questioning, inline multi-perspective analysis, external research, and iterative refinement.

Core workflow: Seed Idea → Expand → Multi-Perspective Explore → Research → Refine → Crystallize → Next Step

Key features:

• brainstorm.md: Complete thought evolution timeline
• Multi-perspective analysis: Creative + Pragmatic + Systematic (serial, inline)
• External research: Web search for inspiration, patterns, and best practices via web.run
• Idea expansion: Progressive questioning and exploration
• Diverge-Converge cycles: Generate options then focus on best paths
• Progress tracking: functions.update_plan for real-time phase progress visibility
• Structured handoff: Terminal gate with execution planning, issue creation, or completion

Auto Mode

When --yes or -y: Auto-confirm exploration decisions, use recommended perspectives, skip interactive scoping.

Quick Start

# Basic usage
/codex:brainstorm-with-file TOPIC="How to improve developer onboarding experience"

# With perspective selection
/codex:brainstorm-with-file TOPIC="New caching strategy" --perspectives=creative,pragmatic,systematic

# Continue existing session
/codex:brainstorm-with-file TOPIC="caching strategy" --continue

# Auto mode (skip confirmations)
/codex:brainstorm-with-file -y TOPIC="Plugin architecture ideas"

Target Topic

$TOPIC

Configuration

Session ID format: BS-{YYYY-MM-DD}-{slug}

• slug: lowercase, alphanumeric + CJK characters, max 40 chars
• date: YYYY-MM-DD (UTC+8)
• Auto-detect continue: session folder + brainstorm.md exists → continue mode

Brainstorm Flow

Step 0: Session Setup
   ├─ Parse topic, flags (--perspectives, --continue, -y)
   ├─ Generate session ID: BS-{date}-{slug}
   ├─ Create session folder (or detect existing → continue mode)
   └─ functions.update_plan (5 phases: Seed → Explore → Refine → Converge → GATE)

Step 1: Seed Understanding
   ├─ Parse topic, identify brainstorm dimensions
   ├─ Role/perspective selection with user (or auto)
   ├─ Initial scoping via functions.request_user_input (mode, focus, constraints)
   ├─ Expand seed into exploration vectors
   └─ Initialize brainstorm.md

Step 2: Divergent Exploration (Inline, No Agents)
   ├─ Detect codebase → search relevant modules, patterns
   │   ├─ Run `ccw spec load --category exploration` (if spec system available)
   │   └─ Use Grep, Glob, Read, mcp__ace-tool__search_context
   ├─ Multi-perspective analysis (serial, inline)
   │   ├─ Creative perspective: innovation, cross-domain, challenge assumptions
   │   ├─ Pragmatic perspective: feasibility, effort, blockers
   │   └─ Systematic perspective: decomposition, patterns, scalability
   ├─ External research via web.run (optional — patterns, best practices, inspiration)
   ├─ Aggregate findings → perspectives.json + research.json
   ├─ Update brainstorm.md with Round 1
   └─ Initial Idea Coverage Check

Step 3: Interactive Refinement (Multi-Round, max 6)
   ├─ Present current ideas and perspectives (Cumulative Context)
   ├─ Record findings to brainstorm.md BEFORE updating Current Ideas
   ├─ Gather user feedback via functions.request_user_input
   ├─ Process response:
   │   ├─ Deep Dive → deeper inline analysis on selected ideas
   │   ├─ Diverge → new inline analysis with different angles
   │   ├─ Challenge → devil's advocate inline analysis
   │   ├─ Merge → synthesize complementary ideas inline
   │   ├─ 外部研究 → web.run for external inspiration/validation
   │   └─ Converge → exit loop for synthesis
   ├─ Update brainstorm.md with round details
   └─ Repeat until user selects converge or max rounds

Step 4: Convergence & Crystallization
   ├─ Consolidate all insights → synthesis.json
   ├─ Update brainstorm.md with final synthesis
   ├─ Batch top-idea review via functions.request_user_input
   └─ MANDATORY Terminal Gate: 执行任务 / 产出Issue / 完成
       ├─ Execute Task → handoff-spec.json with implementation scope
       ├─ Create Issue → display issue creation command
       └─ Done → end workflow

Recording Protocol

CRITICAL: During brainstorming, the following situations MUST trigger immediate recording to brainstorm.md:

Decision Record Format

> **Decision**: [Description of the decision]
> - **Context**: [What triggered this decision]
> - **Options considered**: [Alternatives evaluated]
> - **Chosen**: [Selected approach] — **Reason**: [Rationale]
> - **Rejected**: [Why other options were discarded]
> - **Impact**: [Effect on brainstorming direction]

Narrative Synthesis Format

Append after each round update:

### Round N: Narrative Synthesis
**Starting point**: Based on previous round's [conclusions/questions], this round explored [starting point].
**Key progress**: [New ideas/findings] [confirmed/refuted/expanded] previous understanding of [topic area].
**Decision impact**: User selected [feedback type], directing brainstorming toward [adjusted/deepened/maintained].
**Current state**: After this round, top ideas are [updated idea rankings].
**Open directions**: [remaining exploration angles for next round]

Implementation Details

Phase 0: Session Initialization

const getUtc8ISOString = () => new Date(Date.now() + 8 * 60 * 60 * 1000).toISOString()

// Parse flags
const autoYes = $ARGUMENTS.includes('--yes') || $ARGUMENTS.includes('-y')
const continueMode = $ARGUMENTS.includes('--continue')
const perspectivesMatch = $ARGUMENTS.match(/--perspectives[=\s]([\w,]+)/)
const selectedPerspectiveNames = perspectivesMatch
  ? perspectivesMatch[1].split(',')
  : ['creative', 'pragmatic', 'systematic']

// Extract topic
const topic = $ARGUMENTS.replace(/--yes|-y|--continue|--perspectives[=\s][\w,]+|--max-ideas[=\s]\d+|TOPIC=/g, '').replace(/^["']|["']$/g, '').trim()

// Determine project root
const projectRoot = functions.exec_command('git rev-parse --show-toplevel 2>/dev/null || pwd').trim()

const slug = topic.toLowerCase().replace(/[^a-z0-9\u4e00-\u9fa5]+/g, '-').substring(0, 40)
const dateStr = getUtc8ISOString().substring(0, 10)
const sessionId = `BS-${dateStr}-${slug}`
const sessionFolder = `${projectRoot}/.workflow/.brainstorm/${sessionId}`

// Auto-detect continue: session folder + brainstorm.md exists → continue mode
// If continue → load brainstorm.md + perspectives, resume from last round
functions.exec_command(`mkdir -p ${sessionFolder}`)

// Initialize progress tracking (MANDATORY)
functions.update_plan([
  { id: "phase-1", title: "Phase 1: Seed Understanding", status: "in_progress" },
  { id: "phase-2", title: "Phase 2: Divergent Exploration", status: "pending" },
  { id: "phase-3", title: "Phase 3: Interactive Refinement", status: "pending" },
  { id: "phase-4", title: "Phase 4: Convergence & Crystallization", status: "pending" },
  { id: "next-step", title: "GATE: Post-Completion Next Step", status: "pending" }
])

Phase 1: Seed Understanding

Objective: Parse the initial idea, identify exploration vectors, scope preferences, and initialize the brainstorm document.

Step 1.1: Parse Seed & Identify Dimensions

Match topic keywords against brainstorm dimensions (see Dimensions Reference):

// Match topic text against keyword lists from Dimensions Reference
// If multiple dimensions match, include all
// If none match, default to "technical" and "innovation"
const dimensions = identifyDimensions(topic, BRAINSTORM_DIMENSIONS)

Step 1.2: Role Selection

Recommend roles based on topic keywords, then let user confirm or override.

Professional Roles (recommended based on topic keywords):

Simple Perspectives (fallback — always available):

Selection Strategy:

1. Auto mode: Select top 3 recommended professional roles based on keyword matching
2. Manual mode: Present recommended roles + "Use simple perspectives" option
3. Continue mode: Use roles from previous session

Step 1.3: Initial Scoping (New Session Only)

For new brainstorm sessions, gather user preferences before exploration (skipped in auto mode or continue mode):

if (!autoYes && !continueMode) {
  // Single batch: Mode + Focus + Constraints (max 4 questions per call)
  const scoping = functions.request_user_input({
    questions: [
      {
        header: "Mode",       // max 12 chars
        question: "Select brainstorming intensity:",
        multiSelect: false,
        options: [
          { label: "Balanced (Recommended)", description: "Moderate, 3 perspectives" },
          { label: "Creative", description: "Fast, high novelty, 1 perspective" },
          { label: "Deep", description: "Comprehensive, 3 perspectives + deep refinement" }
        ]
      },
      {
        header: "Focus",
        question: "Select brainstorming focus areas:",
        multiSelect: true,
        options: generateFocusOptions(dimensions) // Dynamic based on dimensions
      },
      {
        header: "Constraints",
        question: "Any constraints to consider?",
        multiSelect: true,
        options: [
          { label: "Existing Arch", description: "Must fit current system" },
          { label: "Time Limited", description: "Short implementation timeline" },
          { label: "Resource Limited", description: "Limited team/budget" },
          { label: "No Constraints", description: "Blue-sky thinking" }
        ]
      }
    ]
  })
}

Step 1.4: Expand Seed into Exploration Vectors

Generate key questions that guide the brainstorming exploration. Done inline — no agent delegation.

Exploration Vectors:

1. Core question: What is the fundamental problem/opportunity?
2. User perspective: Who benefits and how?
3. Technical angle: What enables this technically?
4. Alternative approaches: What other ways could this be solved?
5. Challenges: What could go wrong or block success?
6. Innovation angle: What would make this 10x better?
7. Integration: How does this fit with existing systems/processes?

Analyze the topic inline against user focus areas and constraints to produce 5-7 exploration vectors.

Step 1.5: Initialize brainstorm.md

const brainstormMd = `# Brainstorm Session

**Session ID**: ${sessionId}
**Topic**: ${topic}
**Started**: ${getUtc8ISOString()}
**Dimensions**: ${dimensions.join(', ')}
**Mode**: ${brainstormMode}

## Table of Contents
<!-- TOC: Auto-updated after each round/phase. -->
- [Session Context](#session-context)
- [Current Ideas](#current-ideas)
- [Thought Evolution Timeline](#thought-evolution-timeline)

## Current Ideas
<!-- REPLACEABLE BLOCK: Overwrite (not append) after each round with latest ranked ideas. -->

> To be populated after exploration.

## Session Context
- Focus areas: ${focusAreas.join(', ')}
- Perspectives: ${selectedPerspectiveNames.join(', ')}
- Constraints: ${constraints.join(', ')}
- Mode: ${brainstormMode}

## Exploration Vectors
${explorationVectors.map((v, i) => `${i+1}. ${v}`).join('\n')}

## Initial Decisions
> Record why these perspectives and focus areas were selected.

---

## Thought Evolution Timeline

> Rounds will be appended below as brainstorming progresses.

---

## Decision Trail

> Consolidated critical decisions across all rounds (populated in Phase 4).
`
Write(`${sessionFolder}/brainstorm.md`, brainstormMd)

Success Criteria:

• Session folder created with brainstorm.md initialized
• Brainstorm dimensions identified and user preferences captured
• Initial decisions recorded: Perspective selection rationale, excluded options with reasons
• Exploration vectors generated
• 1-3 perspectives selected

Phase 2: Divergent Exploration

Objective: Gather codebase context and execute multi-perspective analysis to generate diverse viewpoints. All exploration done inline — no agent delegation.

Step 2.1: Detect Codebase & Explore

const hasCodebase = functions.exec_command(`
  test -f package.json && echo "nodejs" ||
  test -f go.mod && echo "golang" ||
  test -f Cargo.toml && echo "rust" ||
  test -f pyproject.toml && echo "python" ||
  test -f pom.xml && echo "java" ||
  test -d src && echo "generic" ||
  echo "none"
`).trim()

if (hasCodebase !== 'none') {
  // 1. Read project metadata (if exists)
  //    - Run `ccw spec load --category exploration` (load project specs)
  //    - Run `ccw spec load --category debug` (known issues and root-cause notes)
  //    - .workflow/specs/*.md (project conventions)

  // 2. Search codebase for relevant content
  //    Use: Grep, Glob, Read, or mcp__ace-tool__search_context
  //    Focus on: modules/components, patterns/structure, integration points, config/dependencies

  // 3. Write findings
  Write(`${sessionFolder}/exploration-codebase.json`, JSON.stringify({
    project_type: hasCodebase,
    relevant_files: [...],    // [{path, relevance, summary}]
    existing_patterns: [...], // [{pattern, files, description}]
    architecture_constraints: [...], // Constraints found
    integration_points: [...], // [{location, description}]
    key_findings: [...],      // Main insights from code search
    _metadata: { timestamp: getUtc8ISOString(), exploration_scope: '...' }
  }, null, 2))
}

Step 2.2: Multi-Perspective Analysis (Serial, Inline)

Analyze from each selected perspective. All analysis done inline by the AI — no agents.

Perspective Definitions:

Serial execution — analyze each perspective sequentially:

const perspectives = ['creative', 'pragmatic', 'systematic']

perspectives.forEach(perspective => {
  // Analyze inline using exploration-codebase.json as context
  // Generate ideas from this perspective's focus
  Write(`${sessionFolder}/perspectives/${perspective}.json`, JSON.stringify({
    perspective: perspective,
    ideas: [        // 3-5 ideas per perspective
      { title: '...', description: '...', novelty: 1-5, feasibility: 1-5, rationale: '...' }
    ],
    key_findings: [...],
    challenged_assumptions: [...],
    open_questions: [...],
    _metadata: { perspective, timestamp: getUtc8ISOString() }
  }, null, 2))
})

Step 2.3: Aggregate Multi-Perspective Findings

// Update progress
functions.update_plan([{ id: "phase-2", title: "Phase 2: Divergent Exploration", status: "in_progress" }])

const synthesis = {
  session_id: sessionId,
  timestamp: getUtc8ISOString(),
  topic,

  // Individual perspective findings
  creative: readJson(`${sessionFolder}/perspectives/creative.json`),
  pragmatic: readJson(`${sessionFolder}/perspectives/pragmatic.json`),
  systematic: readJson(`${sessionFolder}/perspectives/systematic.json`),

  // Cross-perspective synthesis
  synthesis: {
    convergent_themes: [...],    // What all perspectives agree on
    conflicting_views: [...],    // Where perspectives differ
    unique_contributions: [...]  // Insights unique to specific perspectives
  },

  // Aggregated for refinement
  aggregated_ideas: [...],  // Merged and deduplicated ideas from all perspectives
  key_findings: [...]       // Main insights across all perspectives
}
Write(`${sessionFolder}/perspectives.json`, JSON.stringify(synthesis, null, 2))

Step 2.3b: External Research (Optional)

Search for external inspiration, industry best practices, and prior art to enrich brainstorming context.

// Triggered when: topic involves established patterns, industry trends, or competitive landscape
const researchQueries = generateResearchQueries(topic, dimensions)

researchQueries.forEach(query => {
  const results = web.run({ search_query: query })
  // Extract: patterns, inspiration, best practices, case studies
})

// Write research findings
Write(`${sessionFolder}/research.json`, JSON.stringify({
  queries: researchQueries,
  findings: [...],   // [{source, insight, relevance_to_topic}]
  inspiration: [...], // Cross-domain ideas from external sources
  best_practices: [...],
  _metadata: { timestamp: getUtc8ISOString() }
}, null, 2))

// Merge research findings into perspectives.json synthesis
// Update convergent_themes and unique_contributions with external evidence

Step 2.4: Update brainstorm.md

Append Round 1 with exploration results using the Round Documentation Pattern.

Round 1 Sections (Multi-Perspective Exploration):

• Creative Perspective: Novel ideas with novelty/impact ratings
• Pragmatic Perspective: Practical approaches with effort/risk ratings
• Systematic Perspective: Architectural options with tradeoff analysis
• Perspective Synthesis: Convergent themes, conflicts, unique contributions

Step 2.5: Initial Idea Coverage Check

// Check exploration vectors against Round 1 findings
appendToBrainstorm(`
#### Initial Idea Coverage Check (Post-Exploration)
${explorationVectors.map((vector, i) => {
  const status = assessCoverage(vector, explorationFindings)
  return `- ${status.icon} Vector ${i+1}: ${vector} — ${status.detail}`
}).join('\n')}

> Next rounds will focus on uncovered and in-progress vectors.
`)

Success Criteria:

• exploration-codebase.json created with codebase context (if codebase exists)
• perspectives/*.json created for each perspective
• perspectives.json created with aggregated findings and synthesis
• brainstorm.md updated with Round 1 results
• Initial Idea Coverage Check completed
• Key findings recorded with evidence and ratings

Phase 3: Interactive Refinement

Objective: Iteratively refine ideas through multi-round user-guided exploration cycles. Max Rounds: 6. All analysis done inline.

Auto mode behavior (--yes):

• Balanced/Deep mode: Run 2 auto-rounds (1× Deep Dive on top 2 ideas, 1× Challenge on top 3 ideas), then auto-converge
• Creative mode: Run 1 auto-round (1× Diverge), then auto-converge
• Skip user direction prompts; auto-select based on idea scores

Cumulative Context Rule: Each round's analysis MUST include ALL prior findings as context. Never analyze in isolation — always build on:

• Previous rounds' ideas and ratings
• User feedback from all prior rounds
• Research findings (if any)
• Challenged assumptions and their outcomes

Record-Before-Continue Rule: MUST write round findings to brainstorm.md BEFORE updating Current Ideas or presenting next interaction.

Step 3.1: Present Findings & Gather User Direction

Current Understanding Summary (Round >= 2, BEFORE presenting new findings):

• Generate 1-2 sentence recap of top ideas and last round's direction
• Example: "Top ideas so far: [idea1], [idea2]. Last round [deepened/challenged/merged]. Here are the latest findings:"

// Update progress
functions.update_plan([{ id: "phase-3", title: "Phase 3: Interactive Refinement", status: "in_progress" }])

if (!autoYes) {
  // Dynamic options based on round context
  const baseOptions = [
    { label: "Deep Dive", description: "Explore selected ideas in detail" },
    { label: "Diverge More", description: "Generate more ideas from different angles" },
    { label: "Challenge", description: "Devil's advocate — test ideas critically" },
    { label: "Merge Ideas", description: "Combine complementary ideas" }
  ]

  // Add research option if not yet done or if new angles emerged
  if (!researchDone || newAnglesEmerged) {
    baseOptions.push({ label: "外部研究", description: "Search for external inspiration and best practices" })
  }

  // Always include converge as final option
  baseOptions.push({ label: "Ready to Converge", description: "Sufficient ideas, proceed to synthesis" })

  const feedback = functions.request_user_input({
    questions: [{
      header: "Direction",   // max 12 chars
      question: `Brainstorm round ${round}: What would you like to do next?`,
      multiSelect: false,
      options: baseOptions.slice(0, 4) // max 4 options per schema
    }]
  })
}

Step 3.2: Process User Response

Recording Checkpoint: Regardless of option selected, MUST record to brainstorm.md:

• User's original choice and expression
• Impact on brainstorming direction
• If direction changed, record a full Decision Record

Step 3.3: Deep Dive on Selected Ideas

When user selects "deep dive", provide comprehensive inline analysis:

// For each selected idea, analyze inline
selectedIdeas.forEach(idea => {
  const deepDive = {
    title: idea.title,
    detailed_description: '...',     // Elaborated concept
    technical_requirements: [...],   // Implementation needs
    dependencies: [...],             // What this depends on
    challenges: [                    // Risk/challenge matrix
      { challenge: '...', severity: 'high|medium|low', mitigation: '...' }
    ],
    poc_approach: '...',             // Proof-of-concept suggestion
    success_metrics: [...],          // How to measure success
    source_perspectives: [...]       // Which perspectives contributed
  }
  Write(`${sessionFolder}/ideas/${ideaSlug}.md`, formatIdeaMarkdown(deepDive))
})

Step 3.4: Devil's Advocate Challenge

When user selects "challenge", perform inline critical analysis:

selectedIdeas.forEach(idea => {
  const challenge = {
    idea: idea.title,
    objections: [...],               // 3+ strongest objections
    challenged_assumptions: [...],   // Core assumptions tested
    failure_scenarios: [...],        // When/how this fails
    alternatives: [...],             // Competitive/alternative solutions
    survivability_rating: 1-5,       // How well idea survives challenge
    strengthened_version: '...'      // Improved version post-challenge
  }
  // Record in brainstorm.md
})

Step 3.5: Merge Multiple Ideas

When user selects "merge", synthesize inline:

const merged = {
  title: '...',                     // New merged concept name
  description: '...',              // Unified concept description
  source_ideas: [...],             // Which ideas were merged
  elements_from_each: [...],       // What was taken from each source
  contradictions_resolved: [...],  // How conflicts were handled
  combined_strengths: [...],       // New combined advantages
  implementation_considerations: '...'
}
Write(`${sessionFolder}/ideas/merged-idea-${n}.md`, formatMergedIdeaMarkdown(merged))

Step 3.6: Document Each Round

Update brainstorm.md using the Round Documentation Pattern.

Append to Thought Evolution Timeline: User Direction, Decision Log, Ideas Generated/Updated, Analysis Results, Challenged Assumptions, Open Items, Narrative Synthesis.

Replace (not append):

Success Criteria:

• User feedback processed for each round
• brainstorm.md updated with all refinement rounds
• Ideas in ideas/ folder for selected deep-dives
• Exit condition reached (user selects converge or max rounds)

Phase 4: Convergence & Crystallization

Objective: Synthesize final ideas, generate conclusions and recommendations, and offer next steps.

Step 4.1: Consolidate Insights

const synthesis = {
  session_id: sessionId,
  topic,
  completed: getUtc8ISOString(),
  total_rounds: roundCount,
  top_ideas: [                    // Top 5 ranked ideas
    {
      title: '...', description: '...',
      source_perspective: '...',
      score: 1-10,                // Final viability score
      novelty: 1-5,              // Innovation rating
      feasibility: 1-5,          // Implementation feasibility
      key_strengths: [...],
      main_challenges: [...],
      next_steps: [...],
      review_status: 'accepted|modified|rejected|pending'
    }
  ],
  parked_ideas: [...],           // Ideas for future consideration
  key_insights: [...],           // Key learnings from brainstorming
  recommendations: {
    primary: '...',              // Best path forward
    alternatives: [...]          // Other viable options
  },
  follow_up: [                   // Suggested next steps
    { type: 'implement|research|validate', summary: '...' }
  ],
  decision_trail: [              // Consolidated from all phases
    { round: 1, decision: '...', context: '...', chosen: '...', reason: '...', impact: '...' }
  ]
}
Write(`${sessionFolder}/synthesis.json`, JSON.stringify(synthesis, null, 2))

Step 4.2: Final brainstorm.md Update

Synthesis & Conclusions:

• Executive Summary: High-level overview of brainstorming results
• Top Ideas: Ranked list with descriptions and strengths/challenges
• Primary Recommendation: Best path forward with clear rationale
• Alternative Approaches: Other viable options with tradeoff analysis
• Parked Ideas: Future considerations with potential triggers
• Key Insights: Important learnings from the process

Current Ideas (Final):

Decision Trail:

Session Statistics: Total rounds, ideas generated, ideas survived challenges, perspectives used, artifacts generated.

Step 4.3: Interactive Top-Idea Review (skip in auto mode)

Batch review of top ideas (max 4 questions per call, so group top ideas accordingly):

// Update progress
functions.update_plan([{ id: "phase-4", title: "Phase 4: Convergence & Crystallization", status: "in_progress" }])

if (!autoYes) {
  // Batch review: up to 4 ideas per functions.request_user_input call
  const batchSize = 4
  for (let batch = 0; batch < rankedIdeas.length; batch += batchSize) {
    const batchIdeas = rankedIdeas.slice(batch, batch + batchSize)
    const review = functions.request_user_input({
      questions: batchIdeas.map((idea, i) => ({
        header: `Idea #${batch + i + 1}`,   // max 12 chars
        question: `"${idea.title}" (score: ${idea.score}). Your decision:`,
        multiSelect: false,
        options: [
          { label: "Accept", description: "Keep in final recommendations" },
          { label: "Modify", description: "Adjust scope or priority" },
          { label: "Reject", description: "Remove from recommendations" },
          { label: "Accept Rest", description: "Accept all remaining ideas" }
        ]
      }))
    })
    // Process: Accept → "accepted" | Modify → gather text → "modified" | Reject → "rejected"
    // Accept Rest → mark all remaining as "accepted", break outer loop
    // Record review decisions to brainstorm.md Decision Log + update synthesis.json
  }
}

Review Summary (append to brainstorm.md):

### Top Idea Review Summary
| # | Idea | Score | Novelty | Feasibility | Review Status | Notes |
|---|------|-------|---------|-------------|---------------|-------|
| 1 | [title] | 8 | 4 | 3 | Accepted | |
| 2 | [title] | 7 | 5 | 2 | Modified | [notes] |
| 3 | [title] | 6 | 3 | 4 | Rejected | [reason] |

Step 4.4: MANDATORY Terminal Gate (Post-Completion Next Step)

CRITICAL: This gate MUST execute. The workflow MUST NOT end without this functions.request_user_input call.

// Update progress — mark phase 4 complete, activate terminal gate
functions.update_plan([
  { id: "phase-4", title: "Phase 4: Convergence & Crystallization", status: "completed" },
  { id: "next-step", title: "GATE: Post-Completion Next Step", status: "in_progress" }
])

const nextStep = functions.request_user_input({
  questions: [{
    header: "Next Step",    // max 12 chars
    question: "Brainstorming complete. What would you like to do next?",
    multiSelect: false,
    options: [
      { label: "Execute Task", description: "Build implementation scope and handoff spec from top ideas" },
      { label: "Create Issue", description: "Convert top ideas into trackable issues" },
      { label: "Done", description: "End workflow, all artifacts saved" }
    ]
  }]
})

// Handle next step
if (nextStep === "Execute Task") {
  // Build implementation scope from accepted ideas
  // Step A: Identify scope items from top ideas
  // Step B: Generate handoff-spec.json with implementation details
  // Step C: Write handoff-spec.json to session folder
  Write(`${sessionFolder}/handoff-spec.json`, JSON.stringify({

}

// Mark terminal gate complete
functions.update_plan([
  { id: "next-step", title: "GATE: Post-Completion Next Step", status: "completed" }
])

Success Criteria:

• synthesis.json created with complete synthesis
• brainstorm.md finalized with all conclusions
• Terminal gate executed with user's next-step choice
• If "Execute Task": handoff-spec.json created with implementation scope
• Session complete and all artifacts available

Round Documentation Pattern

Each round follows this structure in brainstorm.md:

### Round N - [DeepDive|Diverge|Challenge|Merge] (timestamp)

#### User Input
What the user indicated they wanted to focus on

#### Decision Log
<!-- Use Decision Record Format from Recording Protocol -->

#### Ideas Generated
New ideas from this round with ratings

#### Analysis Results
Detailed findings from this round's analysis
- Finding 1 (evidence: file:line or rationale)
- Finding 2 (evidence: file:line or rationale)

#### Challenged Assumptions
- ~~Previous assumption~~ → New understanding
  - Reason: Why the assumption was wrong

#### Open Items
Remaining questions or exploration directions

#### Narrative Synthesis
<!-- Use Narrative Synthesis Format from Recording Protocol -->
