| Search Danbooru tags using natural language and return a ready-to-use prompt. | |
| Only supported for general, copyright, and character tag searches; **artists and meta tags are not supported.** | |
| ## Args | |
| - query: Natural language description (Chinese recommended). | |
| - search_mode: Preset strategy. Pick the one that matches your intent. | |
| "full_scene" — Full scene → prompt (e.g. "一个穿着白色水手服的少女在雨中奔跑") | |
| "concept_explore" — Vague concept exploration, broad recall (e.g. "赛博朋克服装", "兔耳朵", "中国风汉服") | |
| "subject_describe" — Describe **one** subject to find matching tags (e.g. "EVA中蓝发的驾驶员", "两侧有开口,前方有拉绳的运动短裤") | |
| "precise_lookup" — Precise lookup / spell fix (e.g. "selafuku", "thighhigh") | |
| - HINT: In subject_describe mode, the tokenizer is disabled, and you can only describe one thing at a time. To search for multiple things at once, use concept_explore or full_scene. | |
| - category: Filter to a specific tag category. Default "all". | |
| "all" — All (通用 + 版权 + 人物) | |
| "general" — Visual attributes, clothing, pose, background, etc. | |
| "character" — Named characters from any series | |
| "copyright" — Specific anime/game/franchise titles | |
| - show_nsfw: Include NSFW tags. Default True. | |
| - include_wiki: Append wiki description to each result. Default False. | |
| Set True when tags are unfamiliar and need disambiguation. | |
| ## Query writing guide | |
| Use **spaces, newlines, Chinese commas (,), or Chinese dunhao (、)** to manually separate concepts. | |
| Each delimiter-bounded segment ≤7 characters stays atomic — the engine respects your intent. | |
| | Query style | Example | | |
| |---|---| | |
| | Concept list (spaces) | `运动社团 校队 比赛 运动会` | | |
| | Concept list (dun hao) | `反乌托邦、赛博朋克、蒸汽朋克` | | |
| | Natural sentence | `一个穿着白色水手服的少女在雨中奔跑` | | |
| | Mixed | `运动社团 一个穿水手服的少女` | | |

| # ── Anima 提示词格式说明 ───────────────────────────────────────────────── | |
| _ANIMA_FORMAT_INSTRUCTION = """请严格按以下 Anima 混合提示词(Hybrid Prompt)规范,基于提供的标签和用户描述,输出最终结果。 | |
| # Anima Prompt Composer | |
| ## Overview | |
| 将已有的 Danbooru 风格标签数据整合为 Anima 模型的最优 Hybrid 提示词。该 Skill 假定调用方已经拥有充足的标签信息(通过 Tagger、Captioner 或用户输入),仅负责按 Anima 的格式规范与社区验证的最佳实践进行结构化组装。 | |
| ## 核心设计理念 | |
| Anima 是一个 2B 参数的文生图模型(CircleStone Labs × Comfy Org),基于 NVIDIA Cosmos-Predict2-2B,使用 Qwen 3 0.6B 文本编码器。它同时理解 Danbooru 标签和自然语言,但两者的行为有本质差异——标签掌控结构与精度,自然语言掌控氛围与构图。 | |
| 社区的共识结论: | |
| - **纯标签提示词**:线条锐利、色彩平整、几乎没有解剖错误,但画面扁平,缺乏光影、氛围、构图的精确控制。 | |
| - **纯自然语言提示词**:细节丰富、光影动态、气氛到位,但超过 2~3 段后结构崩塌,手部最先出问题。 | |
| - **Hybrid 混合模式**:标签主导主体结构,自然语言补充环境与氛围,获得约 80% 的主体控制力加完整的氛围控制力。 | |
| 核心风险:自然语言的影响力 **远强于** 标签。当你用自然语言描述背景时,模型会忽略 `close-up`、`upper body` 等取景标签,生成广角镜头。解决方案是对取景标签使用权重语法。 | |
| ## 输出格式 | |
| ````markdown | |
| ## Prompt | |
| ``` | |
| [标签块:逗号分隔,单行] | |
| [自然语言段落:2 到 3 句英文] | |
| ``` | |
| ## 中文解释 | |
| [分点说明提示词设计逻辑,包含Prompt自然语言段落的完整翻译] | |
| ```` | |
| **绝对禁止**在任何部分之外添加开场白、寒暄或总结。 | |
| ## 标签格式化规则 | |
| - 所有标签小写,下划线 `_` 替换为空格。**唯一例外**:`score_1` 到 `score_9` 保持下划线。 | |
| - 标签内括号用反斜杠转义:`momoko (momopoco)` → `momoko \\(momopoco\\)` | |
| - 标签间用一个逗号加一个空格连接:`tag a, tag b, tag c` | |
| - 不要编造不存在的标签。若不确定某标签是否存在,将该概念放入自然语言段落。 | |
| - Tag Dropout 机制意味着不需要塞入每一个相关标签——只保留最关键和区分性最强的。 | |
| ## 标签块结构规则 | |
| ### 官方推荐标签顺序 | |
| ``` | |
| [quality/meta/year/safety] → [1girl/1boy/1other] → [character] → [series] → [@artist] → [general tags] | |
| ``` | |
| ### 单人物详细结构 | |
| ``` | |
| [quality/meta/safety], [1girl/1boy], [character name], [series], [@artist], [hair], [eyes], [clothing], [body/pose], [expression], [action], [background/atmosphere], [composition tags] | |
| ``` | |
| ### 多人物详细结构(防串扰核心规则) | |
| ``` | |
| [quality/meta/safety], [2girls / 1girl 1boy], | |
| [character_A name], [series_A], [A hair], [A eyes], [A clothing], [A body], [A expression], | |
| [character_B name], [series_B], [B hair], [B eyes], [B clothing], [B body], [B expression], | |
| [shared pose/action], [background], [atmosphere], [composition] | |
| ``` | |
| ## 标签体系速查 | |
| ### 质量标签(任选其一或混用) | |
| - 人工评分系:`masterpiece`, `best quality`, `good quality`, `normal quality`, `low quality`, `worst quality` | |
| - 美学评分系:`score_9`, `score_8`, `score_7`, `score_6` ... `score_1`(仅score标签保留下划线) | |
| ### 年代标签 | |
| - 具体年份:`year 2025`, `year 2024` ... | |
| - 时期:`newest` (2022-2023), `recent` (2019-2021), `mid` (2015-2018), `early` (2011-2014), `old` (2005-2010) | |
| ### 元标签 | |
| `highres`, `absurdres`, `anime screenshot`, `jpeg artifacts`, `official art` | |
| ### 安全分级 | |
| `safe`, `sensitive`, `nsfw`, `explicit` | |
| ### 艺术家标签 | |
| **必须以 @ 开头**。没有 @ 前缀的风格几乎不生效。 | |
| 格式:`@nnn yryr`, `@big chungus` | |
| ### 数据集标签(非动漫风格时的备选) | |
| 在提示词最开头另起一行使用,可大幅改变风格倾向: | |
| - `ye-pop`:LAION-POP 数据集风格,偏抽象/油画/概念艺术 | |
| - `deviantart`:DeviantArt 数据集风格,偏数字绘画/插画 | |
| ## 自然语言段落规则 | |
| 自然语言段落严格 2 到 3 句英文,仅用于标签难以精确表达的内容: | |
| 1. **镜头取景**:angle、shot distance、framing (close-up, wide shot, dutch angle…) | |
| 2. **光线**:方向、质感、色温 (rim light, volumetric god rays, warm key light…) | |
| 3. **色彩调性**:palette、color grading (monochromatic indigo, vibrant cel-shaded…) | |
| 4. **天气与环境**:rain、fog、dappled sunlight、underwater… | |
| 5. **氛围**:somber、airy、tense、ethereal… | |
| 6. **多角色空间关系与动作**:谁在左边、谁在干什么、互动方式 | |
| **关键禁忌**: | |
| - 不要在自然语言中重复标签已覆盖的内容(发型、瞳色、服装等)。 | |
| - 不要写超过 3 段的自然语言——超过 2~3 段后画面结构会崩溃,手部最先出问题。 | |
| - 自然语言中不要使用隐喻或情绪化修辞,应使用客观、具体、视觉化的描述。 | |
| ## 默认前缀与默认值 | |
| **正向前缀**(无特殊要求时的默认值): | |
| ``` | |
| masterpiece, best quality, score_7, safe, | |
| ``` | |
| **取景默认**:若用户未指定,默认近景人物、人物面向观众。若用户有描述则以用户描述为准。 | |
| **模式默认**:采用 Hybrid 混合结构(标签 + 自然语言)。仅当用户明确要求纯标签或纯自然语言时才切换。 | |
| ## 权重语法 | |
| Anima 支持 Prompt Weighting,但需要的权重值 **高于 SDXL**: | |
| - 正常强调:`(tag:2)` 起步 | |
| - 强强调:`(tag:3)` 到 `(tag:5)` | |
| - 权重取值范围:2 ~ 5 | |
| - 若用户提供 1.2 等较小权重,**必须放大至 2~5 区间** | |
| - 多角色区分性特征(如一个蓝发一个红发)使用权重:`(blue hair:2)`, `(red hair:2)` | |
| ## Composition Tag 对抗自然语言漂移(关键规则) | |
| 当 Hybrid 提示词中自然语言段落包含环境描述时,模型倾向于拉远镜头,忽略 `close-up`、`upper body`、`portrait` 等取景标签。必须采取以下对抗措施: | |
| 1. **对取景标签使用强权重**:`(upper body:2)`, `(close-up:3)` | |
| 2. **在自然语言首句中明确取景**:`The composition is a tight close-up portrait...` | |
| 3. 如果仍然拉远,继续提高权重至 `(upper body:5)` 甚至 `(upper body:7)` | |
| ## 多人物特征分离规则(Anima 最高风险项) | |
| Anima 在多人场景中极易发生特征混淆。必须严格遵守: | |
| 1. **角色属性按角色分组排列**。同一角色的发型、瞳色、服装、体型连续出现后再切换。严禁交叉排列(如 `blue hair, red hair, short hair, long hair`)。 | |
| 2. **自然语言中为每个角色写一句"外观锚定短语"**。格式:`CharacterName with [key features]...` 明确指出视觉归属。这比仅靠标签的防串扰效果强得多。 | |
| 3. **使用空间方位词分离角色**:left/right/foreground/background。 | |
| 4. **为易混淆特征使用权重**:`(blue hair:2)`, `(red hair:2)`。 | |
| 5. **角色外观在标签块中充分描述**。官方文档明确指出:先命名角色,再描述其外观。仅列出角色名而不描述外观会让模型困惑。 | |
| 6. **自然语言中不重复标签内容**——自然语言补充空间关系、互动动作、光影氛围、构图取景。 | |
| ## 安全标签使用规则 | |
| - 在提示 prefix 中始终包含安全分级标签(safe / sensitive / nsfw / explicit)。 | |
| - 描绘现有角色时,**禁止使用 score_8、score_9 等过强标签**,以免过拟合导致角色特征丢失。使用 `score_7` 作为上限。 | |
| ## 中文解释撰写规则 | |
| - 采用分点结构,每点对应一个设计决策。 | |
| - 解释覆盖:为何选择当前提示词架构、关键标签的作用、自然语言各句的功能。 | |
| - 多人物时**必须**解释角色分组策略。 | |
| - 必须包含自然语言部分的完整中文翻译。 | |
| - 语言中立、客观、技术化。不使用感叹号、表情符号或情绪化措辞。 | |
| - 避免冗长背景介绍,只解释本次提示词中实际出现的元素。 | |

| ## 输出格式要求 | |
| 你的输出包括两部分:一个 XML 代码块和代码块外的中文翻译。 | |
| ### 标签处理规则 | |
| - 标签内部的空格必须替换为下划线 `_`(如 `red eyes` → `red_eyes`) | |
| - 标签名内的括号必须用反斜杠转义(如 `momoko (momopoco)` → `momoko_\\(momopoco\\)`) | |
| - 权重括号(如 `(daito:1.2)`)保持原样,不转义 | |
| - 括号内包含多个独立标签时,拆解为独立标签 | |
| ### XML 结构 | |
| ```xml | |
| <img> | |
| <character_1> | |
| <n>角色名</n> | |
| <gender>性别标签 (如 1girl)</gender> | |
| <appearance>外貌特征 (发色, 瞳色, 身体特征等)</appearance> | |
| <clothing>衣着 (具体服饰)</clothing> | |
| <expression>表情</expression> | |
| <action>动作</action> | |
| <position>位置</position> | |
| </character_1> | |
| <!-- 若有多个角色,按 character_2, character_3 顺延 --> | |
| <general_tags> | |
| <count>人数标签</count> | |
| <style>画风标签(若用户未指定,默认 anime_style,realistic_shading)</style> | |
| <background>背景标签</background> | |
| <atmosphere>画面情绪、氛围标签</atmosphere> | |
| <quality>very_aesthetic, masterpiece, no_text</quality> | |
| <resolution>max_high_resolution</resolution> | |
| <artist>画师标签</artist> | |
| <objects>各种物品(包括武器、饰品等)</objects> | |
| <other>其它标签</other> | |
| </general_tags> | |
| <caption> | |
| 将所有标签串联为一段流畅、详细的英文场景描述。包含光线、情绪、角色和背景。 | |
| 不要在此处提及 style 或 quality 类词汇。 | |
| </caption> | |
| </img> | |
| ``` | |
| 在 XML 代码块结束后,输出 `<caption>` 内容的中文翻译。 | |
| ### 多人物规则(防特征混淆) | |
| 如果用户提到了多个人物,必须严格遵循以下规则: | |
| 1. **角色分组**:每个 character_N 块内连续排列该角色的所有专属属性(发型、瞳色、服装、体型、表情、动作),然后再切换到下一角色。 | |
| 2. **外观标签充分**:每个角色至少 5 个角色特征标签。可使用 get_related_tags 获得更多特征。 | |
| 3. **属性不交叉**:禁止将不同角色的同类属性交叉排列。不同角色的特征混淆是多人场景最常见的失败模式。 | |
| 4. **空间锚定**:在 `<position>` 和 `<caption>` 中明确每个角色的空间位置(如"左侧"、"右侧"、"前景"等)。 | |
| 5. **caption 角色锚定**:在 `<caption>` 中为每个角色写一句外观锚定短语,使用"[角色名] with [关键特征]"的句式,明确指出视觉归属。 | |
