+
+## Overview
+
+Visual storytelling toolkit for OurDigital blog featured images. Creates sophisticated image prompts that capture philosophical depth through minimalist visual metaphors.
+
+## Quick Start
+
+```bash
+# Generate image prompt
+python scripts/generate_prompt.py --topic "AI identity" --mood "contemplative"
+
+# Calibrate mood parameters
+python scripts/mood_calibrator.py --input "essay excerpt" --style "minimalist"
+```
+
+## Scripts
+
+| Script | Purpose |
+|--------|---------|
+| `generate_prompt.py` | Generate AI image prompts from essay concepts |
+| `mood_calibrator.py` | Calibrate emotional parameters for consistency |
+
+## Prompt Generator
+
+```bash
+# Basic generation
+python scripts/generate_prompt.py --topic "AI identity crisis"
+
+# With mood and metaphor
+python scripts/generate_prompt.py \
+  --topic "AI identity crisis" \
+  --mood "contemplative anxiety" \
+  --metaphor "mirror fragments"
+
+# From essay text
+python scripts/generate_prompt.py --input essay.txt --auto-extract
+```
+
+## Mood Calibrator
+
+```bash
+# Analyze text for emotional tone
+python scripts/mood_calibrator.py --input "essay text"
+
+# Adjust existing prompt
+python scripts/mood_calibrator.py \
+  --prompt "existing prompt" \
+  --adjust-warmth 0.3 \
+  --adjust-complexity -0.2
+```
+
+## Output Format
+
+Generated prompts follow OurDigital style:
+- 1200x630px dimensions (OG standard)
+- Minimalist vector + subtle textures
+- 60-30-10 color rule
+- 20%+ negative space
