Asset Generation

资产生成

Use this skill for logos, icon marks, hero/section imagery, and texture motifs.
本技能适用于logo、图标标识、主视觉/板块图像以及纹理图案的生成。

Trigger

触发条件

Run when user asks for:
  • logo exploration or logo revisions
  • better visual assets in design proposals
  • proposal-specific imagery
  • provider comparison (Recraft, OpenAI, Gemini/Nano Banana)
当用户提出以下需求时运行：
  • logo探索或logo修订
  • 设计提案中更优质的视觉资产
  • 提案专属的图像素材
  • 生成工具对比（Recraft、OpenAI、Gemini/Nano Banana）

Core Rules

核心规则

  1. Use all three providers during exploratory rounds unless user opts out:
    • Recraft
    • OpenAI Image (
      gpt-image-1
      )
    • Nano Banana Pro (Gemini image model)
  2. Generate assets in proposal context, not as detached global batch.
  3. Exploration width must match design uncertainty:
    • Early rounds: high style/color diversity
    • Late rounds: narrow around survivors
  4. Logos must pass favicon/app-icon constraints:
    • flat, simple, low-part count
    • legible at 16px/24px
    • works one-color and full-color
  5. If provider outputs are noisy/illustrative, use a deterministic geometric SVG fallback.
  6. Treat user-provided logo references as quality primitives only, never literal templates.
  7. Never produce marks that can be confused with existing company logos.
  1. 除非用户明确要求，否则在探索阶段必须同时使用三款生成工具：
    • Recraft
    • OpenAI Image (
      gpt-image-1
      )
    • Nano Banana Pro（Gemini图像模型）
  2. 生成的资产必须贴合提案上下文，而非独立的批量生成内容。
  3. 探索广度需与设计不确定性匹配：
    • 早期阶段：高风格/色彩多样性
    • 后期阶段：聚焦于筛选出的优质方案
  4. Logo必须满足网站图标/应用图标约束：
    • 扁平化、简洁、元素数量少
    • 在16px/24px尺寸下仍清晰可辨
    • 支持单色和全色彩显示
  5. 若工具输出内容偏噪点/插画风格，需使用确定性几何SVG作为备选方案。
  6. 用户提供的logo参考仅作为质量基准，绝不能作为字面模板直接使用。
  7. 禁止生成可能与现有企业logo混淆的标识。

Reference Archetypes (Quality North Star)

参考原型（质量标杆）

Target mark families like:
  • modular rounded blocks
  • orbiting dot constellation
  • constrained grid/mosaic tiles
  • minimalist key/keyhole symbol
  • 3x3 dot matrix
  • hex-aperture emblem
Avoid mascot illustrations, scene composition, and decorative line clutter.
目标标识风格包括：
  • 模块化圆角块
  • 环绕式点群
  • 受限网格/马赛克 tiles
  • 极简钥匙/锁孔符号
  • 3x3点阵
  • 六边形开口徽章
避免吉祥物插画、场景构图和装饰性线条冗余。

Reference Use Policy (Hard)

参考使用规则（严格执行）

When user provides inspiration logos:
  1. Extract only abstract qualities:
    • simplicity level
    • geometry type
    • corner behavior
    • stroke/fill balance
    • negative-space strategy
  2. Do not reuse exact silhouette, arrangement, or recognizable motif from references.
  3. Do not preserve source colorways unless the user explicitly asks.
  4. Generate at least 4 structural families per batch before narrowing.
  5. Reject anything that looks like "same logo with minor tweaks."
This is a hard requirement. "Inspired by" means transferable principles, not copied form.
当用户提供灵感logo时：
  1. 仅提取抽象特质：
    • 简洁程度
    • 几何类型
    • 边角处理方式
    • 描边/填充平衡
    • 负空间策略
  2. 禁止复用参考素材的精确轮廓、布局或可识别的图案。
  3. 禁止保留参考素材的配色方案，除非用户明确要求。
  4. 每批生成至少4种结构风格后再进行筛选。
  5. 拒绝任何看起来像是“原logo微调版”的方案。
这是硬性要求。“灵感来源于”指的是可迁移的设计原则，而非复制形态。

Complexity Budget (Hard Limits)

复杂度预算（严格限制）

Reject marks that exceed:
  • 8 primary primitives
  • 2 stroke widths
  • 2 brand colors + 1 neutral
  • more than 1 internal detail per major shape
Accept only marks that remain recognizable at 24px without anti-aliasing blur.
拒绝超出以下限制的标识：
  • 超过8个基础几何元素
  • 超过2种描边宽度
  • 超过2种品牌色 + 1种中性色
  • 每个主要形状内的细节超过1处
仅接受在24px尺寸下无抗锯齿模糊仍可识别的标识。

Phase-Aware Breadth

阶段感知的广度策略

Phase A: Wide Exploration (no clear winner yet)

阶段A：广度探索（未确定最优方案）

Per proposal, generate at least:
  • 1 Recraft concept
  • 1 OpenAI concept
  • 1 Nano Banana concept
Diversity matrix (required across batch):
  • Geometry: rounded / angular / mixed
  • Weight: monoline / medium / bold
  • Symbol strategy: abstract / mic-derived / node-derived
  • Palette families: warm, cool, neutral, high-contrast, muted
针对每个提案，至少生成：
  • 1个Recraft方案
  • 1个OpenAI方案
  • 1个Nano Banana方案
多样性矩阵（每批必须覆盖）：
  • 几何风格：圆角/棱角/混合
  • 视觉重量：单线条/中等/粗体
  • 符号策略：抽象/麦克风衍生/节点衍生
  • 调色板系列：暖色调、冷色调、中性色调、高对比度、低饱和度

Phase B: Convergence (2-3 survivors)

阶段B：收敛聚焦（保留2-3个优质方案）

Per proposal, generate:
  • 2 focused variants (best provider + fallback provider)
  • tightly constrained palette and stroke system
针对每个提案，生成：
  • 2个聚焦变体（最优工具 + 备选工具）
  • 严格约束的调色板和描边系统

Proposal-Context Workflow

提案上下文工作流

For each proposal 
7a..7h
:
  1. Read proposal DNA + palette + typography mood.
  2. Generate 3 logos (Recraft/OpenAI/Nano Banana) using that proposal context.
  3. Pick best mark for that proposal only.
  4. Embed into that proposal HTML and tune surrounding spacing/contrast.
  5. Keep alternates for review.
Do not force one logo family across all proposals during exploratory rounds.
For each proposal 
7a..7h
:
  1. 读取提案核心信息 + 调色板 + 排版风格。
  2. 结合提案上下文生成3个logos（Recraft/OpenAI/Nano Banana各一个）。
  3. 仅为该提案挑选最优标识。
  4. 将其嵌入该提案HTML并调整周边间距/对比度。
  5. 保留备选方案供审核。
Do not force one logo family across all proposals during exploratory rounds.

QA Gates (Reject if fails)

QA Gates (Reject if fails)

  • noisy illustration masquerading as logo
  • too many micro-details for favicon scale
  • style clashes with proposal typography/system
  • same colorway/style duplicated across whole batch
  • visible gibberish text baked into background assets
  • mascot/character or scene illustration instead of symbol mark
  • more than one focal object in a logo frame
  • obvious resemblance to known logos or user-provided samples
  • structural near-duplicate across proposal logos

  • too many micro-details for favicon scale
  • style clashes with proposal typography/system

Deterministic Fallback

Deterministic Fallback

When model outputs fail QA, generate a clean SVG mark from geometric primitives. This is not optional for quality: use it to guarantee a production-safe floor.
