# Carousel Generator v2

**World-class Instagram carousel generator** with AI content intelligence, multi-tool visual generation, and professional design systems.

---

## Quick Start

```bash
# Generate from topic
python -m scripts.carousel_generator "GLP-1 for weight loss" --template tips_5

# Generate from JSON structure
python -m scripts.carousel_generator input.json --output ./my-carousel/

# Generate from long-form content (backward mode)
python -m scripts.carousel_generator newsletter.txt

# Generate both 4:5 and 1:1 outputs
python -m scripts.carousel_generator "Statin myths" --template myth_busting --both-ratios
```

Or use in Claude Code:
```
"Create a carousel about statins myth-busting"
"Generate Instagram slides for GLP-1 benefits"
"Turn this newsletter into carousel slides: [paste content]"
```

python -m scripts.carousel_generator "Hypertension myths" --both-ratios

# Custom output directory
python -m scripts.carousel_generator "GLP-1" -o ./client-carousel/
```

---

## Python API

```python
from scripts.carousel_generator import CarouselGenerator
from scripts.models import CarouselConfig, AspectRatio

# Configure
config = CarouselConfig(
    account=1,
    aspect_ratio=AspectRatio.INSTAGRAM_4X5,
    max_slides=10,
    check_contrast=True,
    check_anti_ai=True
)

# Initialize generator
generator = CarouselGenerator(config)

# Generate from topic
result = generator.generate_from_topic(
    "GLP-1 for weight loss",
    template="tips_5",
    use_ai=True
)

print(f"Generated {len(result.slides)} slides to {result.output_directory}")
```

### Generate from JSON Structure

```python
# Create structured input
carousel_json = {
    "topic": "Heart Health Tips",
    "slides": [
        {
            "type": "hook",
            "title": "5 Things Your Cardiologist Wishes You Knew",
            "subtitle": "Evidence-based insights"
        },
        {
            "type": "tips",
            "title": "Tip #1",
            "bullet_points": [
                "LDL target matters more than total cholesterol",
                "Below 100 mg/dL for most, below 70 for high risk"
            ]
        },
        {
            "type": "cta",
            "cta_text": "Follow for more",
            "cta_handle": "@heartdocshailesh"
        }
    ]
}

import json
with open("input.json", "w") as f:
    json.dump(carousel_json, f)

result = generator.generate_from_json(Path("input.json"))
```

### Generate from Long-form Content (Backward Mode)

```python
newsletter_content = """
# The Truth About Statins

Recent meta-analyses have conclusively shown that statins reduce
cardiovascular events by 25-30%. The most common side effect,
muscle pain, occurs in only 5-10% of patients...
"""

result = generator.generate_from_longform(
    newsletter_content,
    content_type="newsletter"
)
```

---

## Quality Checker

The generator automatically runs quality checks:

```python
from scripts.quality_checker import QualityChecker
from scripts.models import Carousel

checker = QualityChecker()

# Run all checks
results = checker.run_all_checks(carousel)

# Generate report
report = checker.generate_report(results)
print(report)
```

### Quality Checks Performed

| Check | Threshold | Description |
|-------|-----------|-------------|
| **text_density** | ≤15 words/slide | Ensures scannability |
| **contrast_ratio** | ≥4.5:1 | WCAG AA compliance |
| **anti_ai** | No AI patterns | Detects AI-generated phrases |
| **slide_count** | 8-10 slides | Optimal engagement |
| **hook_quality** | Question or number | Engaging first slide |
| **cta_presence** | Last slide is CTA | Clear call to action |

### Anti-AI Detection

The checker flags these patterns:
- "It's important to note"
- "In conclusion"
- "Stands as a testament"
- "Groundbreaking" / "Game-changing"
- "Vibrant tapestry"
- Em dash overuse (more than 1 per paragraph)
