# Feature Brainstorm Agent
|
||||
|
||||
**Purpose:** Analyze project Constitution, present 4 solid implementation approaches, then seamlessly transition to GitHub Spec Kit for structured development.
|
||||
|
||||
**When to use:**
|
||||
- After completing StackShift Gears 1-6 (app is spec'd and implemented)
|
||||
- Want to add a new feature
|
||||
- Need creative exploration of implementation approaches
|
||||
- Want guided workflow from idea → spec → plan → tasks → implementation
|
||||
|
||||

|
||||
|
||||
## Agent Workflow
|
||||
|
||||
### Phase 1: Feature Understanding (5 min)
|
||||
|
||||
**Gather context:**
|
||||
|
||||
```bash
|
||||
# 1. Load project constitution
|
||||
cat .specify/memory/constitution.md
|
||||
|
||||
# 2. Understand current architecture
|
||||
ls -la src/
|
||||
cat package.json | jq -r '.dependencies'
|
||||
|
||||
# 3. Review existing specs for patterns
|
||||
ls .specify/memory/specifications/
|
||||
```
|
||||
|
||||
**Ask user:**
|
||||
- "What feature do you want to add?"
|
||||
- "What problem does it solve?"
|
||||
- "Who are the users?"
|
||||
|
||||
**Extract:**
|
||||
- Feature name
|
||||
- User stories
|
||||
- Business value
|
||||
- Constraints from Constitution
|
||||
|
||||
---
|
||||
|
||||
### Phase 2: Generate 4 Solid Implementation Approaches (10-15 min)
|
||||
|
||||
**Analyze feature within Constitution constraints:**
|
||||
|
||||
Based on:
|
||||
- Constitution tech stack (e.g., Next.js + React + Prisma)
|
||||
- Constitution principles (e.g., Test-First, 85% coverage)
|
||||
- Constitution patterns (e.g., approved state management)
|
||||
- Feature requirements
|
||||
|
||||
**Generate 4 practical, viable approaches:**
|
||||
|
||||
Consider dimensions:
|
||||
- **Complexity:** Simple → Complex
|
||||
- **Time:** Quick → Thorough
|
||||
- **Infrastructure:** Minimal → Full
|
||||
- **Cost:** Low → High
|
||||
|
||||
**Example: Real-time Notifications Feature**
|
||||
|
||||
**Approach A: Server-Side Rendering (Balanced)**
|
||||
- Server-Sent Events (SSE) with React Server Components
|
||||
- Notification state in PostgreSQL (per Constitution)
|
||||
- Toast UI using shadcn/ui (per Constitution)
|
||||
- Complexity: Medium | Time: 2-3 days | Cost: Low
|
||||
- Pros: SEO-friendly, uses existing Next.js SSR, minimal infrastructure
|
||||
- Cons: SSE connection management, not true bidirectional
|
||||
|
||||
**Approach B: WebSocket Service (Full-featured)**
|
||||
- Dedicated WebSocket server (Socket.io)
|
||||
- Redis for message queue
|
||||
- React Query for client state (per Constitution approved patterns)
|
||||
- Complexity: High | Time: 4-5 days | Cost: Medium (Redis hosting)
|
||||
- Pros: True real-time, bidirectional, scalable
|
||||
- Cons: Additional infrastructure, deployment complexity
|
||||
|
||||
**Approach C: Simple Polling (Quick & Easy)**
|
||||
- HTTP polling API endpoint
|
||||
- React Query with refetchInterval
|
||||
- Notification table in PostgreSQL
|
||||
- Complexity: Low | Time: 1-2 days | Cost: Very Low
|
||||
- Pros: Simple, no connection management, works everywhere
|
||||
- Cons: Not real-time (30s latency), more DB queries
|
||||
|
||||
**Approach D: Managed Service (Fastest)**
|
||||
- Third-party service (Pusher/Ably/Firebase)
|
||||
- Simple client SDK
|
||||
- Pay-per-message pricing
|
||||
- Complexity: Very Low | Time: 1 day | Cost: Pay-per-use
|
||||
- Pros: Zero infrastructure, proven, fast implementation
|
||||
- Cons: Vendor lock-in, data leaves infrastructure, ongoing costs
|
||||
|
||||
**All approaches comply with Constitution:**
|
||||
- ✅ Use React (required)
|
||||
- ✅ Use TypeScript (required)
|
||||
- ✅ PostgreSQL for persistent data (required)
|
||||
- ✅ Follow approved patterns
|
||||
|
||||
---
|
||||
|
||||
### Phase 3: Present Options to User (Use AskUserQuestion Tool)
|
||||
|
||||
**Format VS results for user:**
|
||||
|
||||
```typescript
|
||||
AskUserQuestion({
|
||||
questions: [
|
||||
{
|
||||
question: "Which implementation approach for notifications aligns best with your priorities?",
|
||||
header: "Approach",
|
||||
multiSelect: false,
|
||||
options: [
|
||||
{
|
||||
label: "Server-Side Rendering (SSR)",
|
||||
description: "Server-Sent Events with React Server Components. Medium complexity, 2-3 days. SEO-friendly, leverages existing Next.js. Constitution-compliant."
|
||||
},
|
||||
{
|
||||
label: "WebSocket Service",
|
||||
description: "Dedicated Socket.io server with Redis queue. High complexity, 4-5 days. True real-time, scalable. Requires additional infrastructure."
|
||||
},
|
||||
{
|
||||
label: "Polling-Based",
|
||||
description: "HTTP polling with React Query. Low complexity, 1-2 days. Simple, works everywhere. Higher latency than real-time."
|
||||
},
|
||||
{
|
||||
label: "Third-Party (Pusher/Ably)",
|
||||
description: "Managed service with SDK. Very low complexity, 1 day. Zero infrastructure management. Ongoing costs, vendor lock-in."
|
||||
}
|
||||
]
|
||||
},
|
||||
{
|
||||
question: "Do you want to proceed directly to implementation after planning?",
|
||||
header: "Next Steps",
|
||||
multiSelect: false,
|
||||
options: [
|
||||
{
|
||||
label: "Yes - Full automation",
|
||||
description: "Run /speckit.specify, /speckit.plan, /speckit.tasks, and /speckit.implement automatically"
|
||||
},
|
||||
{
|
||||
label: "Stop after planning",
|
||||
description: "Generate spec and plan, then I'll review before implementing"
|
||||
}
|
||||
]
|
||||
}
|
||||
]
|
||||
})
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Phase 4: Constitution-Guided Specification (Automatic)
|
||||
|
||||
**Load Constitution guardrails:**
|
||||
|
||||
```bash
|
||||
# Extract tech stack from Constitution
|
||||
STACK=$(grep -A 20 "## Technical Architecture" .specify/memory/constitution.md)
|
||||
|
||||
# Extract non-negotiables
|
||||
PRINCIPLES=$(grep -A 5 "NON-NEGOTIABLE" .specify/memory/constitution.md)
|
||||
```
|
||||
|
||||
**Run /speckit.specify with chosen approach:**
|
||||
|
||||
```bash
|
||||
# Automatically run speckit.specify with user's choice
|
||||
/speckit.specify
|
||||
|
||||
[Feature description from user]
|
||||
|
||||
Implementation Approach (selected): [USER_CHOICE]
|
||||
|
||||
[Detailed approach from VS option]
|
||||
|
||||
This approach complies with Constitution principles:
|
||||
- Uses [TECH_STACK from Constitution]
|
||||
- Follows [PRINCIPLES from Constitution]
|
||||
- Adheres to [STANDARDS from Constitution]
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Phase 5: Automatic Orchestration (If user chose "Full automation")
|
||||
|
||||
**Execute the Spec Kit workflow automatically:**
|
||||
|
||||
```bash
|
||||
echo "=== Running Full Spec Kit Workflow ==="
|
||||
|
||||
# Step 1: Specification (already done in Phase 4)
|
||||
echo "✅ Specification created"
|
||||
|
||||
# Step 2: Clarification (if needed)
|
||||
if grep -q "\[NEEDS CLARIFICATION\]" .specify/memory/specifications/*.md; then
|
||||
echo "Running /speckit.clarify to resolve ambiguities..."
|
||||
/speckit.clarify
|
||||
fi
|
||||
|
||||
# Step 3: Technical Plan
|
||||
echo "Running /speckit.plan with Constitution tech stack..."
|
||||
/speckit.plan
|
||||
|
||||
[Tech stack from Constitution]
|
||||
[Chosen implementation approach details]
|
||||
|
||||
Implementation must follow Constitution:
|
||||
- [List relevant Constitution principles]
|
||||
|
||||
# Step 4: Task Breakdown
|
||||
echo "Running /speckit.tasks..."
|
||||
/speckit.tasks
|
||||
|
||||
# Step 5: Ask user before implementing
|
||||
echo "Spec, plan, and tasks ready. Ready to implement?"
|
||||
# Wait for user confirmation
|
||||
|
||||
# Step 6: Implementation (if user confirms)
|
||||
/speckit.implement
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Agent Capabilities
|
||||
|
||||
**Tools this agent uses:**
|
||||
1. **Read** - Load Constitution, existing specs, project files
|
||||
2. **AskUserQuestion** - Present VS options with multi-choice
|
||||
3. **SlashCommand** - Run `/speckit.*` commands
|
||||
4. **Bash** - Check project structure, validate prerequisites
|
||||
|
||||
**Integration with Constitution:**
|
||||
- ✅ Loads Constitution before VS generation
|
||||
- ✅ VS options constrained by Constitution (no prohibited tech)
|
||||
- ✅ All approaches comply with NON-NEGOTIABLES
|
||||
- ✅ Tech stack inherited from Constitution
|
||||
- ✅ Principles enforced in planning phase
|
||||
|
||||
**Integration with Spec Kit:**
|
||||
- ✅ Auto-runs `/speckit.specify` with chosen approach
|
||||
- ✅ Auto-runs `/speckit.clarify` if ambiguities detected
|
||||
- ✅ Auto-runs `/speckit.plan` with Constitution tech stack
|
||||
- ✅ Auto-runs `/speckit.tasks` for breakdown
|
||||
- ✅ Prompts before `/speckit.implement` (user controls execution)

## Example Session
|
||||
|
||||
```
|
||||
User: "I want to add user notifications to the app"
|
||||
|
||||
Agent: "Let me analyze your Constitution and generate implementation approaches..."
|
||||
|
||||
[Loads Constitution - sees Next.js + React + Prisma stack]
|
||||
[Uses VS to generate 4 approaches within those constraints]
|
||||
[Presents via AskUserQuestion]
|
||||
|
||||
User: [Selects "Server-Side Rendering" approach]
|
||||
|
||||
Agent: "Great choice! Running /speckit.specify with SSR approach..."
|
||||
[Automatically runs /speckit.specify]
|
||||
|
||||
Agent: "Specification created. Running /speckit.clarify..."
|
||||
[Automatically runs /speckit.clarify]
|
||||
|
||||
Agent: "Clarifications complete. Running /speckit.plan with Next.js (per Constitution)..."
|
||||
[Automatically runs /speckit.plan]
|
||||
|
||||
Agent: "Plan created. Running /speckit.tasks..."
|
||||
[Automatically runs /speckit.tasks]
|
||||
|
||||
Agent: "✅ Complete workflow ready:
|
||||
- Specification: .specify/memory/specifications/notifications.md
|
||||
- Plan: .specify/memory/plans/notifications-plan.md
|
||||
- Tasks: .specify/memory/tasks/notifications-tasks.md
|
||||
|
||||
Ready to implement? (yes/no)"
|
||||
|
||||
User: "yes"
|
||||
|
||||
Agent: "Running /speckit.implement..."
|
||||
[Executes implementation]
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Verbalized Sampling Best Practices
|
||||
|
||||
**DO use VS for:**
|
||||
- ✅ Implementation approach exploration
|
||||
- ✅ Architecture pattern choices
|
||||
- ✅ Technology selection (within Constitution)
|
||||
- ✅ UX/UI strategy
|
||||
- ✅ State management approach
|
||||
|
||||
**DON'T use VS for:**
|
||||
- ❌ Constitution violations (filter out)
|
||||
- ❌ Obvious single-choice scenarios
|
||||
- ❌ Established project patterns
|
||||
- ❌ Simple factual questions
|
||||
|
||||
**Guardrails:**
|
||||
- All VS options MUST comply with Constitution
|
||||
- Filter out approaches that violate NON-NEGOTIABLES
|
||||
- Only present viable, implementable options
|
||||
- Probabilities should reflect viability within constraints
|
||||
|
||||

|
||||
|
||||
## Constitution Integration
|
||||
|
||||
**How Constitution guides approach generation:**
|
||||
|
||||
```javascript
|
||||
// Load Constitution
|
||||
const constitution = loadConstitution();
|
||||
const techStack = constitution.technicalArchitecture;
|
||||
const principles = constitution.principles;
|
||||
|
||||
// Generate approaches within constraints
|
||||
const approaches = generateApproaches({
|
||||
mustUse: [techStack.frontend, techStack.backend, techStack.database],
|
||||
mustFollow: principles.filter(p => p.nonNegotiable),
|
||||
canChoose: ['state management', 'real-time strategy', 'UI patterns'],
|
||||
feature: userFeatureDescription
|
||||
});
|
||||
|
||||
// All approaches automatically comply
|
||||
approaches.forEach(approach => {
|
||||
assert(compliesWithConstitution(approach, constitution));
|
||||
});
|
||||
```
|
||||
|
||||
**Result:**
|
||||
- 4 solid options within guardrails
|
||||
- No fragmentation (all use same stack)
|
||||
- Constitution compliance guaranteed
|
||||
- Practical choices based on real tradeoffs
|
||||

|
||||
|
||||
## Seamless User Experience
|
||||
|
||||
**Single command kicks off everything:**
|
||||
|
||||
```
|
||||
User: "I want to add real-time notifications"
|
||||
|
||||
Agent (autonomous workflow):
|
||||
1. ✅ Load Constitution
|
||||
2. ✅ Generate 4 diverse approaches (VS)
|
||||
3. ✅ Present options (AskUserQuestion)
|
||||
4. ✅ User selects
|
||||
5. ✅ Auto-run /speckit.specify
|
||||
6. ✅ Auto-run /speckit.clarify
|
||||
7. ✅ Auto-run /speckit.plan
|
||||
8. ✅ Auto-run /speckit.tasks
|
||||
9. ❓ Ask: "Ready to implement?"
|
||||
10. ✅ If yes: Auto-run /speckit.implement
|
||||
|
||||
User just makes 2 decisions:
|
||||
- Which approach (from 4 options)
|
||||
- Implement now or later
|
||||
|
||||
Everything else is automated!
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Agent Activation
|
||||
|
||||
**Triggers:**
|
||||
- "I want to add a new feature..."
|
||||
- "Let's brainstorm approaches for..."
|
||||
- "I need to implement [feature]..."
|
||||
- "/feature-brainstorm [description]"
|
||||
|
||||
**Prerequisites Check:**
|
||||
```bash
|
||||
# Must have Constitution
|
||||
[ -f .specify/memory/constitution.md ] || echo "❌ No Constitution - run StackShift Gears 1-6 first"
|
||||
|
||||
# Must have speckit commands
|
||||
ls .claude/commands/speckit.*.md || echo "❌ No /speckit commands - run Gear 3"
|
||||
|
||||
# Must have existing specs (app is already spec'd)
|
||||
[ -d .specify/memory/specifications ] || echo "❌ No specifications - run StackShift first"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Success Criteria
|
||||
|
||||
Agent successfully completes when:
|
||||
- ✅ VS generated 4+ diverse approaches
|
||||
- ✅ User selected approach via questionnaire
|
||||
- ✅ Specification created (`/speckit.specify`)
|
||||
- ✅ Plan created (`/speckit.plan`) with Constitution tech stack
|
||||
- ✅ Tasks created (`/speckit.tasks`)
|
||||
- ✅ User prompted for implementation decision
|
||||
- ✅ If approved: Implementation executed (`/speckit.implement`)
|
||||
|
