Can I vibe code Persado?

1. SYSTEM OVERVIEW: Build a micro-SaaS application that replaces Persado's marketing copy generation engine. The app uses Claude 3.5 Sonnet to generate high-converting email subject lines, SMS messages, and banner text categorized by emotional motivators (Achievement, Urgency, Exclusivity, Safety, Gratitude).

2. DATA MODEL:
- Campaign: id, name, target_audience, brand_tone_guidelines, created_at.
- CopyVariant: id, campaign_id, channel (email_subject, sms, banner), emotion_tag, generated_text, baseline_score, status (draft, active, archived).
- PerformanceMetric: id, copy_variant_id, impressions, clicks, conversions, revenue, updated_at.
- PromptTemplate: id, emotion_tag, system_prompt, few_shot_examples, conversion_weight.

3. CORE ENGINE & API INTEGRATION:
- POST /api/generate-copy: Accepts campaign_id, product_details, target_emotion, and channel. Calls Anthropic Claude API using structured outputs (JSON schema) to return 5 distinct text variants mapped to emotional levers.
- Validate generated text against length constraints (e.g., SMS max 160 chars, subject lines max 60 chars) and prohibited word lists for brand safety.
- GET /api/variants: Lists generated variants alongside predicted performance scores derived from past campaign metrics.

4. FEEDBACK & ATTRIBUTION LOOP:
- POST /api/telemetry/event: Ingests conversion data via Webhook from Shopify/Klaviyo (events: email_open, email_click, order_completed) tagged with copy variant ID.
- Calculate CTR and Conversion Rate per variant.
- Run a nightly cron job that evaluates high-performing copy variants (CTR > top 10th percentile), extracts their syntactic structure, and injects them as few-shot examples into PromptTemplate data store for future generation calls.

5. FAILURE MODES & OUT OF SCOPE:
- Fallback: If Anthropic API times out, return default cached human-written copy.
- Out of scope: Direct automated execution inside enterprise MarTech platforms like Adobe Experience Manager; focus on Webhooks and API-driven deployment.
