Image Prompt Designer

Builds AI image prompts using Strategy A (shared Art Direction Prefix for visual consistency across the article's images — count from brief.image_count, default 6).

Inputs

• workspace/{task_id}/image_slots.json
• projects/{slug}/brand-identity.json (colors, founded, mission)
• projects/{slug}/brand-config.json (voice_pair, industry, target_locale)
• workspace/{task_id}/angle.json (format_id, hook)
• references/image/style-presets.md — 12 visual styles
• references/image/format-style-mapping.md — 24 format × style mapping
• references/image/negative-prompts.md — universal + category negatives

Output

workspace/{task_id}/image-prompts.json — ⛔ prompts MUST be a JSON array of objects (each with a slot_id), NEVER an object keyed by slot_id. The dict-keyed shape silently broke chart-render, real-photo sourcing, the placeholder lint, and the publish gate on 2026-06-29; the schema-validate hook now blocks a dict-shaped write.
