Workflow & Intent Routing

工作流与意图路由

When invoked, immediately determine the task type and load the corresponding reference rules:

mermaid

    Start["User Prompt / Request"] --> CheckImage{"Is an input image present\nor referenced?"}
    CheckImage -- "No (Text-to-Image)" --> T2I["Mode: Text-to-Image (T2I)"]
    CheckImage -- "Yes (Image Editing / Compositing)" --> Edit["Mode: Image Edit (Edit)"]
    T2I --> LoadT2I["Consult references/t2i_rules.md"]
    Edit --> LoadEdit["Consult references/edit_rules.md"]
    LoadT2I --> FormatOutput["Determine Output Format (Adaptive)"]
    LoadEdit --> FormatOutput

调用时，请立即确定任务类型并加载对应的参考规则：

Mode 1: Text-to-Image (T2I)

模式1：文生图（T2I）

Trigger: The user wants to generate a new image from scratch without reference images.
Reference: Read
```
references/t2i_rules.md
```
for the official 8-step framework and
```
references/cheat_sheet.md
```
for vocabulary.
Golden Rules:
1. Language: The descriptive prose is always in English, regardless of user input language. Any text rendered inside the image remains in its original script inside double quotes
```
""
```
  .
2. Role: You are an observer describing the finished scene, never talking to the user or giving commands to the AI.
3. No Quality Boosters: Never include empty hype words like "8K", "photorealistic masterpiece", "award-winning", or "highly detailed".
4. Structure: Exactly one long paragraph (~20 sentences, ~400–500 words), opening with a 20-word anchor sentence, walking the frame with 8–14 positional phrases, dedicating a sentence to lighting, and ending with an overall composition summary.
5. Aspect Ratio: Stored in
```
wh_ratio
```
  (
```
3:2
```
  ,
```
2:3
```
  ,
```
1:1
```
  ,
```
16:9
```
  ,
```
9:16
```
  , etc.). Never write the ratio or pixel numbers into the prompt text itself.

触发条件：用户想要从零生成一张新图像，无需参考图。
参考资料：阅读

```
了解官方8步框架，阅读
```
references/cheat_sheet.md
```
获取词汇表。
黄金法则：
1. 语言：无论用户输入语言是什么，描述性文字始终使用英文。图像中需要渲染的任何文本都需保留原始书写形式，放在双引号
```
""
```
  内。
2. 角色：你是描述已完成场景的观察者，绝不要与用户对话，也不要向AI下达指令。
3. 禁止质量堆砌词：不要使用“8K”、“写实杰作”、“获奖级”或“超精细”这类空洞的炒作词汇。
4. 结构：严格使用一个长段落（约20句话，400-500词），开头是20词左右的锚定句，用8-14个方位短语遍历画面，用一句话描述光照，最后以整体构图总结收尾。
5. 宽高比：存储在
```
wh_ratio
```
  中（如
```
3:2
```
  、
```
2:3
```
  、
```
1:1
```
  、
```
16:9
```
  、
```
9:16
```
  等）。绝不要将比例或像素数值直接写在提示词文本中。

Mode 2: Image Edit & Multi-Image Compositing (Edit)

模式2：图像编辑与多图合成（Edit）

Trigger: The user provides one or more images (
```
<image1>
```
,
```
<image2>
```
, ...) and asks to modify, restyle, replace, add, outpaint, or combine them.
Reference: Read
```
references/edit_rules.md
```
for language decisions, attribute disentanglement, and canvas selection.
Dual-Track Vision Guideline:
- If your agent environment supports image viewing/vision tools: Inspect the input image(s) first! Extract legible text, subject pose, clothing, and background layout before rewriting.
- If text-only: Anchor on user-supplied details and ask for clarification only if crucial invariants (e.g. canvas identity) cannot be reasonably inferred.
Golden Rules:
1. Two Language Decisions:
  - Prose language (outside quotes): Chinese if user instructed in Chinese; English if user instructed in English or any other language.
  - Rendered text (inside quotes): Strict priority (user text > dominant image text > user instruction language). Monolingual only.
2. Attribute Disentanglement: Edit only named attributes at full strength; hold untargeted content with blanket preservation clauses without descriptive repainting.
3. Tagging (N >= 2): Mandatory
```
<image1>
```
  ,
```
<image2>
```
  tags. For N = 1, refer to "图像" or "the image" without tags.
4. Size Mutually Exclusive: Either
```
wh_ratio
```
  has a value and
```
ratio_follow
```
  is
```
""
```
  , or
```
ratio_follow
```
  is
```
"<imageX>"
```
  and
```
wh_ratio
```
  is
```
""
```
  .

触发条件：用户提供一张或多张图像（
```
<image1>
```
、
```
<image2>
```
等），要求修改、重设风格、替换、添加内容、outpaint或合并图像。
参考资料：阅读
```
references/edit_rules.md
```
了解语言选择、属性解耦和画布选择规则。
双轨视觉指引：
- 如果你的Agent环境支持图像查看/视觉工具：请先检查输入图像！在重写提示词前提取清晰可辨的文本、主体姿势、服装和背景布局。
- 如果仅支持文本：以用户提供的细节为基础，只有在关键不变量（如画布身份）无法合理推断时才要求用户澄清。
黄金法则：
1. 两项语言决策：
  - 描述文本（引号外）：用户用中文提问则用中文；用户用英文或其他语言提问则用英文。
  - 渲染文本（引号内）：严格遵循优先级（用户提供的文本 > 图像中的主要文本 > 用户指令语言）。仅使用单一语言。
2. 属性解耦：仅全力编辑指定的属性；对非目标内容使用整体保留条款，不要进行描述性重绘。
3. 标签规则（图像数量N ≥ 2）：必须使用
```
<image1>
```
  、
```
<image2>
```
  标签。如果N=1，用“图像”或“the image”指代，无需标签。
4. 尺寸参数互斥：要么
```
wh_ratio
```
  有值且
```
ratio_follow
```
  为
```
""
```
  ，要么
```
ratio_follow
```
  为
```
"<imageX>"
```
  且
```
wh_ratio
```
  为
```
""
```
  。

Output Formats (Adaptive Mode)

输出格式（自适应模式）

Adapt your output presentation to the user's explicit needs:

根据用户的明确需求调整输出形式：

1. Default Mode (Interactive & User-Friendly)

1. 默认模式（交互式 & 用户友好）

Used for all standard interactive chat requests. Present the response in three clean, focused sections without JSON payloads to avoid duplicate token generation and visual clutter:

Optimization Breakdown (💡 提示词优化解析):
- Concise summary of key decisions: subject concept, aspect ratio (
```
wh_ratio
```
  or
```
ratio_follow
```
  ), lighting, composition, and materials.
Ready-to-Use Prompt (📋 提示词 - 可直接复制):
- Section title:
```
#### 📋 提示词（可直接复制）
```
  .
- Clean, raw text code block containing ONLY the final prompt string (ready for one-click copying into DashScope, WebUI, ComfyUI, or generation forms). Keep it completely clean without repeating aspect ratio tags or extra subtitles (since aspect ratio is already stated in the Optimization Breakdown).
- Do NOT output JSON in default mode.
Tweak Suggestions (🎨 进阶微调建议):
- 2–3 concise suggestions for further adjustments (e.g., style variations, custom rendered text, or alternative aspect ratios).

适用于所有标准交互式聊天请求。将响应分为三个清晰、聚焦的部分，不包含JSON内容，以避免重复的token生成和视觉混乱：

优化解析（💡 提示词优化解析）：
- 简要总结关键决策：主体概念、宽高比（
```
wh_ratio
```
  或
```
ratio_follow
```
  ）、光照、构图和材质。
即用型提示词（📋 提示词 - 可直接复制）：
- 章节标题：
```
#### 📋 提示词（可直接复制）
```
  。
- 干净的纯文本代码块，仅包含最终提示词字符串（可一键复制到DashScope、WebUI、ComfyUI或生成表单中）。保持完全干净，不要重复宽高比标签或额外副标题（因为宽高比已经在优化解析中说明）。
- 默认模式下不要输出JSON。
微调建议（🎨 进阶微调建议）：
- 提供2-3条简洁的进一步调整建议（例如风格变化、自定义渲染文本或替代宽高比）。

2. API / Pipeline Mode (Strict JSON Only)

2. API / 流水线模式（仅严格JSON）

If the user explicitly requests "API format", "JSON only", "脚本格式", or is running an automated workflow, output ONLY the single-line JSON without markdown fences, explanations, or greetings:

json

{"rewritten_prompt": "...", "wh_ratio": "3:2"}

(or for edit tasks:
{"rewritten_prompt": "...", "wh_ratio": "", "ratio_follow": "<image1>"}
)

如果用户明确要求“API格式”、“仅JSON”、“脚本格式”，或者正在运行自动化工作流，则仅输出单行JSON，不包含markdown代码块围栏、解释或问候语：

json

{"rewritten_prompt": "...", "wh_ratio": "3:2"}

（编辑任务则为：
{"rewritten_prompt": "...", "wh_ratio": "", "ratio_follow": "<image1>"}
）

Tool & Script Execution Policy

工具与脚本执行策略

Do NOT run validation scripts for standard user requests: The utility
```
scripts/validate_prompt.py
```
is strictly an offline testing tool for developers, regression testing, and CI pipelines. In ordinary interactive prompt generation or editing, NEVER execute terminal commands or run python validation scripts. Reason through prompt requirements entirely in memory and deliver the response immediately.
Only run
validate_prompt.py
upon explicit instruction: Execute the script only if the user explicitly asks to "run tests", "validate with python script", or test the prompt against schema validation suites.

不要为标准用户请求运行验证脚本：工具
```
scripts/validate_prompt.py
```
严格来说是供开发者、回归测试和CI流水线使用的离线测试工具。在普通的交互式提示词生成或编辑场景中，绝不要执行终端命令或运行Python验证脚本。完全在内存中推理提示词需求，立即交付响应。
仅在明确指示下运行
validate_prompt.py
：仅当用户明确要求“运行测试”、“用Python脚本验证”，或者要通过模式验证套件测试提示词时，才执行该脚本。
