Mode 1: Task Brief Generation

Input

interface TaskBriefInput {
  userRequest: string;          // "Add catalogos feature"
  detectedRepos?: string[];     // ["signage_service", "cloud_front"]
  architecture?: string;        // From supermemory
  constraints?: string[];       // ["No refactors", "UI actual"]
}

Output

# Task Brief

## Context
<Background info from supermemory>
<Why this task is needed>
<Repos affected and their roles>

## Scope

### In Scope
- [ ] Feature X implementation in repo A
- [ ] API endpoint Y in repo B
- [ ] UI component Z in repo C

### Out of Scope
- Refactoring existing code
- Changing UI design patterns
- Performance optimizations (unless blocking)

## Definition of Done
- [ ] E2E_TRACE documented (UI → API → DB → UI)
- [ ] All affected repos compile and pass gates
- [ ] No `any` types introduced
- [ ] Contracts cross-repo validated
- [ ] Tests pass (if existing test suite)

## Constraints
- Use existing UI patterns (no new design system)
- Follow architectural conventions in docs/architecture.md
- Maintain backward compatibility

## Technical Notes
<Architecture considerations>
<Known gotchas>
<Suggested approach>

Generation Rules

Context Section:

• Load architecture from supermemory
• Explain WHY task is needed (business context)
• List repos and their roles in E2E flow

Scope Section:

• Be specific about what WILL be done
• Be explicit about what WON'T be done
• Use checkboxes for trackability

Definition of Done:

• Include E2E_TRACE requirement
• Include quality gates (compile, tests, no-any)
• Include contract validation if multi-repo
• Be achievable (don't add impossible requirements)

Constraints:

• NO refactors (unless explicitly requested)
• Follow existing patterns
• Maintain backward compatibility
• Specific to project (from supermemory)

Mode 2: Phase Brief Generation

Input

interface PhaseBriefInput {
  phaseName: string;           // "discovery" | "contracts" | "implementation"
  taskContext: string;         // Task Brief content
  repos: string[];             // Repos for this phase
  previousPhaseResults?: any;  // Results from previous phase
}

Output

# Phase Brief: Discovery

## Phase Goal
Identify all files and contracts affected by adding catalogos feature across 5 repos.

## Repos Affected
- signage_service
- cloud_tag_back
- cloud_front
- ftp_signed_proxy
- etouch

## Definition of Done
- [ ] List of relevant files per repo (top 10)
- [ ] Contracts identified (DTOs, endpoints, events)
- [ ] E2E flow parcial documented
- [ ] Dependency order determined

## Inputs
<Context loaded from supermemory>
<Previous phase results if applicable>

## Expected Outputs
- File list with roles (controller, service, DTO, UI component)
- Contract signatures (API endpoints with request/response)
- E2E flow diagram (ASCII or Mermaid)
- Implementation order recommendation

## Constraints
- READ-ONLY phase (no code changes)
- Focus on catalogos-related files only
- Ignore unrelated features

Generation Rules

Phase Goal:

• Single sentence, specific, achievable
• Clear success criteria

Definition of Done:

• Specific deliverables for this phase
• Checkboxes for trackability
• No unrealistic expectations

Inputs/Outputs:

• Clear interface contract between phases
• Structured format (lists, signatures, diagrams)

Mode 3: Gate Request Generation

Input

interface GateRequestInput {
  phaseSummary: string;        // What was implemented
  repos: string[];             // Repos modified
  filesChanged: string[];      // Top files changed
  e2eTrace: string;            // E2E_TRACE documented
  commandsRun: string[];       // Gates run
}

Output

# Gate Request

## PHASE_SUMMARY
- Repos afectados: signage_service, cloud_tag_back, cloud_front
- Archivos tocados (top 10):
  - signage_service/src/api/catalogos.ts (new)
  - signage_service/src/db/schema/catalogos.ts (new)
  - cloud_front/src/pages/CatalogosPage.tsx (new)
  - ...
- Qué se implementó:
  - Database table `catalogos` con migration
  - API endpoint GET /api/catalogos
  - Frontend page para listar catálogos
- Riesgos/notas:
  - New table requires DB migration
  - API endpoint is public (no auth required)

## E2E_TRACE
1. Entry: User clicks "Catálogos" in etouch menu
2. Navigation: Router navigates to /catalogos in cloud_front
3. Frontend Client: useCatalogos() hook fetches data
4. HTTP Request: GET /api/catalogos to signage_service
5. Backend Service: catalogosService.list() queries DB
6. Database: SELECT * FROM catalogos ORDER BY created_at DESC
7. Response: {id, nombre, imagen, created_at}[] as JSON
8. UI Render: CatalogosGrid displays cards with images
9. User sees: Grid of catálogos with images

## COMMANDS_RUN
```bash
# signage_service
cd signage_service
pnpm lint → ✅ passed
pnpm typecheck → ✅ passed
pnpm build → ✅ passed

# cloud_front
cd cloud_front
pnpm lint → ✅ passed
pnpm typecheck → ✅ passed
pnpm build → ✅ passed

NO-ANY SCAN

oc-no-any signage_service cloud_front
→ No new 'any' types detected

FILES_CHANGED

• signage_service: 8 files (5 new, 3 modified)
• cloud_tag_back: 2 files (1 new, 1 modified)
• cloud_front: 6 files (4 new, 2 modified)

Total: 16 files changed

GATE_REQUEST

Validar:

• E2E_TRACE consistente con diff
• UI encaja con actual patterns
• Contratos cross-repo OK (CatalogoDTO coincide)

## Semantic Understanding Features

### 1. Auto-Detect Repos Affected

User: "Add logout button to the app"

Semantic Analysis:

• "logout" → auth-related
• "button" → UI component
• "app" → likely frontend

Auto-detected repos:

• cloud_front (UI)
• signage_service (API for logout endpoint)

Generated Scope: ✅ Add logout button to navigation bar ✅ Call POST /api/auth/logout endpoint ✅ Clear local session storage ✅ Redirect to login page

❌ Refactor entire auth system ❌ Change login flow

### 2. Infer E2E Flow

User: "Add dashboard charts for analytics"

Semantic Analysis:

• "dashboard" → UI page
• "charts" → data visualization
• "analytics" → requires data aggregation

Inferred E2E Flow:

1. User navigates to /dashboard
2. Frontend fetches data from GET /api/analytics/summary
3. Backend aggregates from database
4. Frontend renders charts with Chart.js
5. User sees visualizations

Generated Technical Notes:

• Consider chart library: Chart.js vs Recharts
• Data aggregation may be expensive (consider caching)
• Responsive design for mobile dashboards

### 3. Consistency Checking

User input: "Add real-time notifications without changing backend"

Consistency Check: ❌ FAILED

Issue: Real-time notifications REQUIRE backend changes:

• WebSocket server or SSE endpoint
• Event emission system
• Notification storage

Suggested Fix: Either:

1. Allow backend changes (WebSocket endpoint)
2. Use polling instead of real-time (no backend change needed)

Generated Warning: ⚠️ Constraint conflict detected: "real-time notifications" requires backend changes, but you specified "without changing backend"

Please clarify approach.

## Integration con Orchestrator

### Workflow

USER: /task catalogos

Orchestrator:

1. Parse user request: "catalogos"
2. AUTO-TRIGGER intelligent-prompt-generator:
   • Mode: Task Brief
   • Input: "catalogos", detected repos, architecture
3. Generator produces optimized Task Brief:
   • Context loaded from supermemory
   • Scope clearly defined
   • Definition of Done with E2E_TRACE
   • Constraints from architecture docs
4. Orchestrator uses generated Task Brief to delegate to builder

### Example: Generated Task Brief

```markdown
# Task Brief: Catálogos Feature

## Context

Adding catálogos feature to allow users to browse product catalogs organized by category.

**Architecture** (from supermemory):
- signage_service: Backend API (Fastify + PostgreSQL)
- cloud_tag_back: Additional backend services
- cloud_front: Frontend UI (Next.js + React)
- ftp_signed_proxy: Asset proxy for images
- etouch: Entry point menu

**E2E Flow Pattern** (from docs/architecture.md):
etouch (entry) → cloud_front (UI) → signage_service (API) → DB

## Scope

### In Scope
- [ ] Database table `catalogos` with migration
- [ ] API endpoint GET /api/catalogos in signage_service
- [ ] Frontend page /catalogos in cloud_front
- [ ] FTP proxy paths for catálogo images
- [ ] Menu entry in etouch linking to /catalogos

### Out of Scope
- Catálogo editing UI (admin panel)
- Filtering/search functionality (future)
- Pagination (if catalog count < 50)

## Definition of Done
- [ ] E2E_TRACE documented (etouch → cloud_front → signage_service → DB → UI)
- [ ] Database migration runs successfully
- [ ] GET /api/catalogos returns catalogos list
- [ ] CatalogosPage renders grid with images
- [ ] All repos pass gates (lint, typecheck, build)
- [ ] No `any` types introduced
- [ ] CatalogoDTO contract matches across repos

## Constraints
- Use existing UI patterns (card grid like ProductsPage)
- Follow API conventions in signage_service/src/api/README.md
- Image URLs must use ftp_signed_proxy
- Maintain backward compatibility (no breaking changes)

## Technical Notes

**Database Schema**:
```sql
CREATE TABLE catalogos (
  id SERIAL PRIMARY KEY,
  nombre VARCHAR(255) NOT NULL,
  imagen VARCHAR(512),
  created_at TIMESTAMP DEFAULT NOW()
);

API Signature:

GET /api/catalogos
Response: Catalogo[]

interface Catalogo {
  id: number;
  nombre: string;
  imagen: string | null;
  created_at: string;
}

Frontend Component:

• Use CatalogosGrid similar to ProductsGrid
• Images:
• Empty state: "No hay catálogos disponibles"

Known Gotchas:

• DB migration must run before API starts
• Image URLs from DB may be absolute or relative (handle both)
• etouch menu requires rebuild after adding entry

## Best Practices

1. **Context Loading** - Always load from supermemory first
2. **Scope Clarity** - Be explicit about in/out of scope
3. **Achievable DoD** - Don't add impossible requirements
4. **Consistency** - Check for contradictions
5. **Examples** - Include code snippets when helpful
6. **Warnings** - Alert about risks and gotchas

---

## Notas

- **Supermemory required** - Generator works best with context
- **Iterative** - Generated briefs can be refined based on feedback
- **Not magic** - Requires good user input and architecture docs
- **Version control** - Save generated briefs for future reference
