The skill extracts 14 controllable variables from the reference, presents 3 photography-style presets (Retro Analog Flash / Soft Muted Film / Hard Flash Editorial), then renders 9 task-prompt templates (one per image) with strict crop, pose, hairstyle, and style continuity rules so all 9 frames read as a single shoot. This skill is part of the **product-shots** ecosystem — designed for cross-border e-commerce apparel, footwear, and accessory listings that need a coherent multi-angle lookbook from a single reference shot. ## Engagement Principles These rules apply across every Section. Read before acting. 1. **Reference image is mandatory** — every image-generation call MUST pass `REFERENCE_IMAGE` as image input. Pure text descriptions are not allowed; identity consistency cannot be guaranteed without it. 2. **Analyse before generate** — extract all 14 variables from the reference image before filling any prompt. Never guess defaults, never skip extraction. 3. **Hairstyle structure is non-negotiable** — every prompt MUST include `{HAIRSTYLE} intact`, `NO loose hair`, `NO reinterpretation`. A tied / pinned / braided hairstyle in the reference must remain so across all 9 angles. 4. **Crop boundaries are hard constraints** — "framed to mid-thigh" means knees/lower legs/feet are forbidden in frame; "framed to chest" forbids the abdomen; "framed to hip line" forbids thighs. Treat each frame's crop as a verifiable rule, not a hint. 5. **Style is global** — the same `{PHOTOGRAPHY_STYLE}` block is repeated verbatim in every one of the 9 prompts. No image may look cleaner / more digital / higher-contrast than the others. 6. **Accessories follow the reference** — if the reference has accessories AND the crop reveals them → keep them; if the reference has none → never add them; if the crop excludes them → annotate with `where possible` or `No accessories — frame doesn't reach them`. 7. **Pause for style selection** — if the user has not specified a style and has not uploaded a style reference image, present the 3 presets via `` chips (do not auto-pick a default). 8. **Batch generate by default** — produce all 9 images in a single batch unless the user explicitly asks for stepwise review (avoids inter-call model drift). 9. **Match the user's language** — respond in the language the user writes in. Never switch unprompted. ## Execution Procedure ``` generate_multi_angle_series(user_request) → 9_images # Step 0 — Pin hard constraints (MUST, before any decision) load references/hard-constraints.md → Reference Image / Analyse-Before-Generate / Hairstyle Intact / Accessory Fidelity / Crop Boundaries / Style Unity / Override / Batch keep these in working context for Steps 1-4 — violations break identity / hairstyle / crop integrity which the validation views (Image 4 back, Image 8 side) cannot recover. # Step 1 — Reference image gate if user did NOT upload REFERENCE_IMAGE: abort with: "This skill requires a reference image to guarantee identity consistency. Please upload a photo and retry." # NEVER fall back to text-only description. # Step 2 — Extract 14 variables from reference (Vision pass) extracted = extract_variables(REFERENCE_IMAGE) → see references/variables-and-workflow.md §Variables (14 fields, extraction specs) REQUIRED = REFERENCE_IMAGE, HAIR_COLOR, HAIRSTYLE, SKIN_TONE, EYE_COLOR, FACE_SHAPE, OUTFIT, BACKGROUND_COLOR, PHOTOGRAPHY_STYLE, ASPECT_RATIO OPTIONAL = HAIR_ACCESSORIES, BAG, JEWELRY, OTHER_ACCESSORIES (default "none") if any required field cannot be extracted with confidence → ask the user to clarify (do NOT silently default). # Step 3 — Photography style selection if has_explicit_style_specification(user_request) → use it elif has_style_reference_image(context) → derive from that image else: PAUSE — emit the 3 preset images + 5 chips (see references/photography-style-presets.md §Selection Output) # Step 4 — Fill 9 task-prompt templates (single batch) for image_id in 1..9: prompt = task_template[image_id] .format(**extracted, PHOTOGRAPHY_STYLE=chosen_style) # Each prompt repeats the full {PHOTOGRAPHY_STYLE} block verbatim. # Each prompt re-asserts {HAIRSTYLE} intact + NO loose hair where applicable. batch_generate(prompts, reference_image=REFERENCE_IMAGE) # Step 5 — Self-check gate (re-validate against hard-constraints) for each rule in references/hard-constraints.md §Rules: assert rule holds across all 9 outputs critical checks: - Image 4 (back view) — hairstyle structure visible from behind, no loose hair - Image 8 (side profile) — hairstyle structure visible from side, no loose hair - Image 5 (extreme close-up) — only eyes/nose/lips visible, no forehead/chin/shoulders - All 9 — same {PHOTOGRAPHY_STYLE} signature (lighting / shadow direction / grain) if any check fails → regenerate the affected image(s) # Step 6 — User overrides (re-render selectively) on user override of any extracted variable: → see references/variables-and-workflow.md §Variable Override Logic HAIRSTYLE / HAIR_COLOR / HAIR_ACCESSORIES → re-render images 1-9 OUTFIT → re-render 1, 2, 3, 4, 6, 7, 8, 9 (skip 5) BAG / JEWELRY → re-render 1, 2, 3, 6, 9 (in-frame ones) PHOTOGRAPHY_STYLE → re-render images 1-9 ``` ## TOC of Module Files - `references/hard-constraints.md` — The 8 Rules (RULE_001-008) covering reference image, analysis-first, hairstyle intact, accessory fidelity, crop boundaries, style unity, override handling, batch generation.

Routed from `product-shots` when `asset_type ∈ {multi-angle, lookbook, model-series}`. - `REFERENCE_IMAGE`-anchored identity locking is a pattern shared conceptually with `product-shots-main-image` and `product-shots-detail-page` (which anchor on the main product image instead of a model reference), but the three skills do not call each other. - Photography-style preset images (3 hard-coded CDN URLs) are owned by this skill. - Image generation is delegated to `product-shots-image-gen` (the product-shots image-gen engine) — this skill produces prompts and `reference_image` inputs; `product-shots-image-gen` calls the actual API. ## Tooling The skill emits prompts + reference image binding. Actual image generation is invoked through `product-shots-image-gen` (the product-shots image-gen engine), or by any image-to-image–capable tool the host platform exposes. Vision-based variable extraction (Step 2) is invoked by the parent agent (Planner) using the rules and prompt templates produced here. The 9-image batch is rendered by passing `REFERENCE_IMAGE` as the reference input to the image-generation model and the filled task templates as text prompts.
