Pitch Deck Generator

Pitch Deck Generator Skill

Purpose

Guide Claude through the pitch deck generation workflow using the project's architecture (React + Supabase + OpenAI Edge Functions).

Architecture Overview

Frontend: /src/pages/PitchDeckWizard.tsx Backend: /supabase/functions/pitch-deck-assistant/index.ts Database: pitch_conversations table (stores chat history) Tables: presentations, profiles, pitch_conversations

Workflow Steps

1. User Journey

User → Chat Interface → Edge Function → OpenAI API → Stream Response
     ↓
Progress Tracking (0-100%)
     ↓
Generate Deck Button (appears at 80%+)
     ↓
Create Presentation → Redirect to /presentations/{id}/outline

2. Key Files to Check

Frontend Chat:

• src/pages/PitchDeckWizard.tsx - Main wizard interface
• src/hooks/usePresentations.ts - Data fetching logic

Backend:

• supabase/functions/pitch-deck-assistant/index.ts - Chat endpoint
• supabase/functions/generate-pitch-deck/index.ts - Deck generation

Database:

• pitch_conversations - Stores chat progress
• presentations - Stores generated decks

Common Issues & Fixes

Issue 1: AI Not Responding

Symptom: Chat message sent but no response Check:

# Verify Edge Function is deployed
supabase functions list | grep pitch-deck-assistant

# Check function logs
supabase functions logs pitch-deck-assistant --tail

Fix: Redeploy if not active

cd supabase/functions/pitch-deck-assistant
supabase functions deploy pitch-deck-assistant

Issue 2: Progress Not Updating

Symptom: Progress bar stuck at same percentage Check Database:

SELECT id, completeness, collected_data
FROM pitch_conversations
ORDER BY created_at DESC LIMIT 1;

Fix: Ensure completeness field updates in Edge Function

Issue 3: Generate Button Not Appearing

Symptom: Chat completes but no button Check:

• Frontend: PitchDeckWizard.tsx line ~120 (button visibility logic)
• Condition: completeness >= 80 Fix: Verify progress reaches 80%+ in database

Issue 4: RLS Policy Blocking Access

Symptom: 401 errors when fetching presentations Check:

-- Verify RLS is enabled
SELECT tablename, rowsecurity FROM pg_tables
WHERE tablename = 'presentations';

-- Check if presentation is public or owned by user
SELECT id, is_public, profile_id
FROM presentations
WHERE id = '{presentation_id}';

Fix: Set is_public = true for test presentations

Testing Checklist

Quick Test (2 minutes)

# 1. Start dev server
pnpm dev

# 2. Navigate to wizard
# http://localhost:8080/pitch-deck-wizard

# 3. Send test message
# "I want to create a pitch deck for TestCorp, an AI company"

# 4. Verify response appears
# ✅ AI responds
# ✅ Progress bar updates
# ✅ No console errors

Full E2E Test (5 minutes)

1. Open wizard: /pitch-deck-wizard
2. Complete conversation (3-4 messages)
3. Verify progress reaches 80%+
4. Click "Generate Deck"
5. Wait for redirect to /presentations/{id}/outline
6. Verify all 10 slides render

Edge Function Structure

Request Format

{
  "conversationId": "uuid",
  "message": "User message text",
  "messages": [
    {"role": "user", "content": "Previous message"},
    {"role": "assistant", "content": "Previous response"}
  ]
}

Response Format (Streaming)

data: {"type":"progress","completeness":20,"message":"AI response chunk"}
data: {"type":"message","content":"More text"}
data: {"type":"complete"}

Environment Variables

Required in Edge Function (Supabase secrets):

• OPENAI_API_KEY - OpenAI API key
• SUPABASE_URL - Project URL
• SUPABASE_ANON_KEY - Public key

Check secrets:

supabase secrets list

Set secret:

supabase secrets set OPENAI_API_KEY=sk-...

Debugging Commands

Check Edge Function Status

supabase functions list

View Live Logs

supabase functions logs pitch-deck-assistant --tail

Test Edge Function Directly

curl -X POST \
  "https://dhesktsqhcxhqfjypulk.supabase.co/functions/v1/pitch-deck-assistant" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer ${SUPABASE_ANON_KEY}" \
  -d '{"message":"Test message"}'

Check Database State

-- Latest conversations
SELECT id, completeness, created_at
FROM pitch_conversations
ORDER BY created_at DESC LIMIT 5;

-- Recent presentations
SELECT id, title, created_at
FROM presentations
ORDER BY created_at DESC LIMIT 5;

Performance Optimization

Frontend

• Use React.memo for chat messages
• Debounce progress updates (max 1/second)
• Stream responses (don't wait for complete response)

Backend

• Use OpenAI streaming API
• Return chunks immediately (don't buffer)
• Update database in background

Database

• Add index on pitch_conversations.profile_id
• Add index on presentations.profile_id

Security Checklist

• RLS enabled on pitch_conversations ✅
• RLS enabled on presentations ✅
• API keys only in Edge Functions (never frontend) ✅
• User can only access own conversations ✅
• Public presentations accessible to all ✅

Quick Reference

Start Development:

pnpm dev

Deploy Edge Function:

supabase functions deploy pitch-deck-assistant

Check Logs:

supabase functions logs pitch-deck-assistant --tail

Test Locally:

• Open: http://localhost:8080/pitch-deck-wizard
• Send message
• Verify response

This skill guides Claude through the complete pitch deck generation workflow, from frontend to backend to database.
