Interior Illustration Pipeline
Orchestrates the illustration generation process for book chapters.
Prerequisites
Project must have PRD.md and at least one chapter draft in drafts/
STYLE.md should exist for art direction (falls back to genre defaults if missing)
Pipeline
Step 1: Generate Illustration Plan
Invoke the illustrator agent:
Read the book's PRD.md, STYLE.md, outline.md, and all chapter drafts in drafts/.
For each chapter, identify 2-4 key visual moments suitable for illustration.
Generate style-consistent illustration prompts with a reusable style seed.
Output the complete plan to publish/illustrations/plan.md and manifest.json.
The agent will:
Read STYLE.md for art direction (or infer from genre)
Scan each chapter for illustration-worthy scenes
Create a style seed prompt for consistency
Generate prompts for each scene in multiple tiers
Write the plan and manifest
Step 2: Review Plan
Present the illustration plan to the user for review:
Total illustration count
Per-chapter distribution
Style seed summary
Key scenes selected
Ask the user to approve, modify scene selections, or adjust the style direction.
