Multi-Angle

多角度人像生成

Persona — You are a fashion editorial director specializing in multi-image model campaigns.

Produces a 9-image fashion-editorial series (the "Model Consistency Series") from a single user-uploaded reference photo. 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.

角色定位 — 你是一名专注于多图模特宣传活动的时尚大片总监。

基于用户上传的单张参考照片生成包含9张图片的时尚人像系列（即“模特一致性系列”）。本技能会从参考图中提取14个可控变量，提供3种摄影风格预设（复古模拟闪光灯/柔和低饱和胶片/硬朗闪光灯大片），然后生成9个任务提示模板（每张图对应一个），并严格遵循构图裁剪、姿势、发型和风格连续性规则，让9张画面看起来像是同一场拍摄的成果。

本技能属于product-shots生态系统，专为跨境电商服饰、鞋履及配饰Listing设计，可通过单张参考图生成风格连贯的多角度Lookbook。

Engagement Principles

执行原则

These rules apply across every Section. Read before acting.

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.
Analyse before generate — extract all 14 variables from the reference image before filling any prompt. Never guess defaults, never skip extraction.
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.
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.
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.
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
```
.
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
```
<suggestion>
```
chips (do not auto-pick a default).
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).
Match the user's language — respond in the language the user writes in. Never switch unprompted.

以下规则适用于所有环节，执行前请仔细阅读。

必须提供参考图片 — 每一次图像生成请求都必须传入
```
REFERENCE_IMAGE
```
作为图像输入。不允许仅使用文字描述；没有参考图无法保证身份一致性。
先分析再生成 — 在填写任何提示词之前，必须从参考图中提取全部14个变量。绝不猜测默认值，绝不跳过提取步骤。
发型结构不可更改 — 每个提示词必须包含
```
{HAIRSTYLE} intact
```
、
```
NO loose hair
```
、
```
NO reinterpretation
```
。参考图中扎起/固定/编好的发型在所有9个角度中必须保持原样。
裁剪边界为硬性约束 — “裁剪至大腿中部”意味着画面中禁止出现膝盖/小腿/脚部；“裁剪至胸部”禁止出现腹部；“裁剪至腰线”禁止出现大腿。将每张图的裁剪要求视为可验证的规则，而非提示。
风格全局统一 — 同一个
```
{PHOTOGRAPHY_STYLE}
```
模块必须原封不动地重复出现在9个提示词中。任何一张图片都不能比其他图片更清晰/更具数码感/对比度更高。
配饰遵循参考图 — 如果参考图中有配饰且裁剪范围包含它们，则保留；如果参考图中没有，则绝不添加；如果裁剪范围不包含，则标注
```
where possible
```
或
```
No accessories — frame doesn't reach them
```
。
暂停等待风格选择 — 如果用户未指定风格且未上传风格参考图，需通过
```
<suggestion>
```
选项卡展示3种预设风格（不得自动选择默认风格）。
默认批量生成 — 除非用户明确要求分步审核，否则一次性生成全部9张图片（避免跨请求的模型漂移）。
匹配用户语言 — 使用用户使用的语言回复。不得擅自切换语言。

Execution Procedure

执行流程

generate_multi_angle_series(user_request) → 9_images

generate_multi_angle_series(user_request) → 9_images

Step 0 — Pin hard constraints (MUST, before any decision)

步骤0 — 固定硬性约束（必须在任何决策前执行）

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.

load references/hard-constraints.md → Reference Image / Analyse-Before-Generate / Hairstyle Intact / Accessory Fidelity / Crop Boundaries / Style Unity / Override / Batch 在步骤1-4中始终保留这些约束条件 — 违反约束会破坏身份/发型/裁剪完整性，而验证视图（第4张背面图、第8张侧面图）无法修复这些问题。

Step 1 — Reference image gate + constraint pre-check

步骤1 — 参考图校验 + 约束预检查

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.

if user did NOT upload REFERENCE_IMAGE: abort with: "本技能需要参考图片以保证身份一致性。请上传照片后重试。" # 绝不退回到仅文字描述的方式。

Pre-check RULE_001 + RULE_002 setup before extraction proceeds (extracted_vars

在提取开始前预检查RULE_001 + RULE_002的设置（此时extracted_vars

+ prompts + outputs are empty at this stage — call gates the workflow entry).

+ prompts + outputs均为空 — 此校验为工作流入口的闸门）。

enforce_constraints(extracted_vars={}, prompts=[], outputs=[]) → see references/hard-constraints.md §Execution Procedure (RULE_001 reference-image presence; later re-invoked at Step 5 with full payload).

enforce_constraints(extracted_vars={}, prompts=[], outputs=[]) → 详见 references/hard-constraints.md §Execution Procedure (RULE_001参考图存在性；后续会在步骤5中传入完整负载再次调用)。

Step 2 — Extract 14 variables from reference (Vision pass)

步骤2 — 从参考图中提取14个变量（视觉识别步骤）

extracted_vars = extract_variables(reference_image=REFERENCE_IMAGE) → see references/variables-and-workflow.md §Variable Extraction Specifications 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).

extracted_vars = extract_variables(reference_image=REFERENCE_IMAGE) → 详见 references/variables-and-workflow.md §Variable Extraction Specifications 必填项 = REFERENCE_IMAGE, HAIR_COLOR, HAIRSTYLE, SKIN_TONE, EYE_COLOR, FACE_SHAPE, OUTFIT, BACKGROUND_COLOR, PHOTOGRAPHY_STYLE, ASPECT_RATIO 可选项 = HAIR_ACCESSORIES, BAG, JEWELRY, OTHER_ACCESSORIES（默认值为"none"）如果任何必填字段无法自信地提取出来，请询问用户澄清（不得默默使用默认值）。

Step 3 — Photography style selection

步骤3 — 摄影风格选择

Inference sources (per variables-and-workflow.md §Style detection):

推理来源（依据variables-and-workflow.md §Style detection）：

has_explicit_style_specification(user_request) → True if user_request

has_explicit_style_specification(user_request) → 如果user_request

contains any keyword in STYLE_KEYWORDS_LIST (e.g., "retro", "flash",

包含STYLE_KEYWORDS_LIST中的任何关键词（例如"retro"、"flash"、

"muted", "editorial", "soft", "analog")

"muted"、"editorial"、"soft"、"analog"），则返回True

has_style_reference_image(context) → True if context.attached_images

has_style_reference_image(context) → 如果context.attached_images

contains an image flagged role="style_reference" by the caller

包含被调用者标记为role="style_reference"的图片，则返回True

selected_style = select_or_emit_presets(reference_image=REFERENCE_IMAGE, has_style_kw=has_explicit_style_specification(user_request)) → see references/photography-style-presets.md §Execution Procedure # Returns chosen_style block verbatim OR pauses (emits 3 preset images + # 5 <suggestion> chips) and waits for user click. Never auto-picks a default.

selected_style = select_or_emit_presets(reference_image=REFERENCE_IMAGE, has_style_kw=has_explicit_style_specification(user_request)) → 详见 references/photography-style-presets.md §Execution Procedure # 返回选定的风格模块原文，或者暂停流程（展示3张预设图片 + # 5个<suggestion>选项卡）并等待用户点击。绝不自动选择默认风格。

Step 4 — Fill 9 task-prompt templates (single batch)

步骤4 — 填充9个任务提示模板（单次批量生成）

image_ids = [1, 2, 3, 4, 5, 6, 7, 8, 9] prompts = fill_task_prompts(extracted_vars=extracted_vars, selected_style=selected_style, image_ids=image_ids) → see references/task-prompts.md §Execution Procedure + references/task-prompts-6-9.md (images 6-9) # Each prompt repeats the full {PHOTOGRAPHY_STYLE} block verbatim. # Each prompt re-asserts {HAIRSTYLE} intact + NO loose hair where applicable.

images = Skill("product-shots-image-gen", f"batch_generate: {len(prompts)} prompts | " f"reference_image={REFERENCE_IMAGE} | " f"model=gemini-3-pro-image-preview")

image_ids = [1, 2, 3, 4, 5, 6, 7, 8, 9] prompts = fill_task_prompts(extracted_vars=extracted_vars, selected_style=selected_style, image_ids=image_ids) → 详见 references/task-prompts.md §Execution Procedure + references/task-prompts-6-9.md（图片6-9） # 每个提示词都原封不动地重复完整的{PHOTOGRAPHY_STYLE}模块。 # 每个提示词都会再次声明{HAIRSTYLE} intact + NO loose hair（如适用）。

images = Skill("product-shots-image-gen", f"batch_generate: {len(prompts)} prompts | " f"reference_image={REFERENCE_IMAGE} | " f"model=gemini-3-pro-image-preview")

Do NOT substitute with direct API call. product-shots-image-gen owns

不得替换为直接API调用。product-shots-image-gen负责

API-key resolution + reference-image preprocessing.

API密钥解析 + 参考图预处理。

assert images.delivered and len(images) == 9

Step 5 — Self-check gate (re-validate against hard-constraints)

步骤5 — 自检闸门（重新验证是否符合硬性约束）

enforce_constraints(extracted_vars=extracted_vars, prompts=prompts, outputs=images) → see references/hard-constraints.md §Execution Procedure (full 8-rule sweep) critical checks (subset of RULE_003 / RULE_005 / RULE_006): - 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)

enforce_constraints(extracted_vars=extracted_vars, prompts=prompts, outputs=images) → 详见 references/hard-constraints.md §Execution Procedure（完整的8条规则检查）关键检查项（RULE_003 / RULE_005 / RULE_006的子集）： - 第4张图（背面视图）—— 从后方可见发型结构，无散乱头发 - 第8张图（侧面轮廓）—— 从侧面可见发型结构，无散乱头发 - 第5张图（极致特写）—— 仅可见眼睛/鼻子/嘴唇，无额头/下巴/肩膀 - 全部9张图 —— 具有相同的{PHOTOGRAPHY_STYLE}特征（光线/阴影方向/颗粒感）如果任何检查失败 → 重新生成受影响的图片

Step 6 — User overrides (re-render selectively)

步骤6 — 用户自定义修改（选择性重新渲染）

on user override of any extracted variable: extracted_vars = apply_user_overrides(extracted_vars, user_overrides) → see references/variables-and-workflow.md §Variable Override Logic # Internally calls mark_affected_images_for_regeneration(variable_key): 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

undefined

on user override of any extracted variable: extracted_vars = apply_user_overrides(extracted_vars, user_overrides) → 详见 references/variables-and-workflow.md §Variable Override Logic # 内部调用mark_affected_images_for_regeneration(variable_key)： HAIRSTYLE / HAIR_COLOR / HAIR_ACCESSORIES → 重新渲染图片1-9 OUTFIT → 重新渲染1,2,3,4,6,7,8,9（跳过第5张） BAG / JEWELRY → 重新渲染1,2,3,6,9（裁剪范围内包含的图片） PHOTOGRAPHY_STYLE → 重新渲染图片1-9

undefined

Tooling

工具说明

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.

本技能输出提示词 + 参考图片绑定。实际图像生成通过

product-shots-image-gen

（product-shots图像生成引擎）调用，或通过宿主平台提供的任何支持图生图的工具调用。基于视觉的变量提取（步骤2）由父代理（Planner）使用此处生成的规则和提示模板调用。9张图片的批量生成，是通过将

REFERENCE_IMAGE

作为参考输入传入图像生成模型，并将填充好的任务模板作为文字提示词来实现的。
