Flow

CODEBLOCK3

Step 0: Load Preferences ⛔ BLOCKING

Check EXTEND.md existence (priority: project → user):
CODEBLOCK4

CODEBLOCK5

Result	Action
Found	Load, display summary → Continue
Not found

⛔ Run first-time setup (references/config/first-time-setup.md) → Save → Continue |

CRITICAL: If not found, complete setup BEFORE any other steps or questions.

Step 1: Analyze Content

1. Save reference images (if provided) → references/workflow/reference-images.md
Save source content (if pasted, save to source.md)
Analyze content: topic, tone, keywords, visual metaphors
Deep analyze references ⚠️: Extract specific, concrete elements (see reference-images.md)
Detect language: Compare source, user input, EXTEND.md preference
Determine output directory: Per File Structure rules

⚠️ People in Reference Images:

If reference images contain people who should appear in the cover:

- Model supports --ref (default): Copy image to refs/, pass via --ref at generation. No description file needed — the model sees the face directly.
Model does NOT support --ref (Jimeng, Seedream 3.0): Create refs/ref-NN-{slug}.md with per-character description (hair, glasses, skin tone, clothing). Embed as MUST/REQUIRED instructions in prompt text.

See reference-images.md for full decision table.

Step 2: Confirm Options ⚠️

MUST use AskUserQuestion tool to present options as interactive selection — NOT plain text tables. Present up to 4 questions in a single AskUserQuestion call (Type, Palette, Rendering, Font + Settings). Each question shows the recommended option first with reason, followed by alternatives.

Full confirmation flow and question format: references/workflow/confirm-options.md

Condition	Skipped	Still Asked
INLINECODE29 or INLINECODE30	6 dimensions	Aspect ratio (unless `--aspect`)
All 6 + `--aspect` specified

All | None |

Step 3: Create Prompt

Save to prompts/cover.md. Template: references/workflow/prompt-template.md

CRITICAL - References in Frontmatter:

- Files saved to refs/ → Add to frontmatter references list
Style extracted verbally (no file) → Omit references, describe in body
Before writing → Verify: INLINECODE37

Reference elements in body MUST be detailed, prefixed with "MUST"/"REQUIRED", with integration approach.

Step 4: Generate Image

1. Backup existing cover.png if regenerating
Check image generation skills; if multiple, ask preference
Process references from prompt frontmatter:

- direct usage → pass via --ref (use ref-capable backend) - style/palette → extract traits, append to prompt

4. Generate: Call skill with prompt file, output path, aspect ratio
On failure: auto-retry once

Step 5: Completion Report

Image Modification

Action	Steps
Regenerate	Backup → Update prompt file FIRST → Regenerate
Change dimension

Backup → Confirm new value → Update prompt → Regenerate |

Composition Principles

- Whitespace: 40-60% breathing room
Visual anchor: Main element centered or offset left
Characters: Simplified silhouettes; NO realistic humans
Title: Use exact title from user/source; never invent

imgs-subdir: {article-dir}/imgs/
independent（默认）: cover-image/{topic-slug}/

/

├── source-{slug}.{ext}    # 源文件

├── refs/                  # 参考图片（如有提供）

│   ├── ref-01-{slug}.{ext}

│   └── ref-01-{slug}.md   # 描述文件

├── prompts/cover.md       # 生成提示词

└── cover.png              # 输出图片
标识符: 2-4个单词，短横线命名。冲突时：追加-YYYYMMDD-HHMMSS

流程
输入 → [步骤0：偏好设置] ─┬─ 找到 → 继续

                               └─ 未找到 → 首次设置 ⛔ 阻塞 → 保存EXTEND.md → 继续

        ↓

分析 + 保存参考 → [输出目录] → [确认：6个维度] → 提示词 → 生成 → 完成

                                     （如果使用--quick或全部指定则跳过）
步骤0：加载偏好设置 ⛔ 阻塞
检查EXTEND.md是否存在（优先级：项目 → 用户）：

bash

macOS, Linux, WSL, Git Bash


test -f .baoyu-skills/baoyu-cover-image/EXTEND.md && echo project

test -f ${XDGCONFIGHOME:-$HOME/.config}/baoyu-skills/baoyu-cover-image/EXTEND.md && echo xdg

test -f $HOME/.baoyu-skills/baoyu-cover-image/EXTEND.md && echo user
powershell

PowerShell（Windows）


if (Test-Path .baoyu-skills/baoyu-cover-image/EXTEND.md) { project }

$xdg = if ($env:XDGCONFIGHOME) { $env:XDGCONFIGHOME } else { $HOME/.config }

if (Test-Path $xdg/baoyu-skills/baoyu-cover-image/EXTEND.md) { xdg }

if (Test-Path $HOME/.baoyu-skills/baoyu-cover-image/EXTEND.md) { user }
结果 操作
找到 加载，显示摘要 → 继续
未找到
 ⛔ 运行首次设置（references/config/first-time-setup.md）→ 保存 → 继续 |
关键: 如果未找到，在任何其他步骤或问题之前完成设置。
步骤1：分析内容
1. 保存参考图片（如有提供）→ references/workflow/reference-images.md
保存源内容（如粘贴，保存到source.md）
分析内容：主题、语气、关键词、视觉隐喻
深度分析参考 ⚠️：提取具体、明确的元素（参见reference-images.md）
检测语言：比较源内容、用户输入、EXTEND.md偏好
确定输出目录：根据文件结构规则
⚠️ 参考图片中的人物：
如果参考图片包含人物且应出现在封面中：
- 模型支持--ref（默认）：将图片复制到refs/，生成时通过--ref传递。无需描述文件——模型直接看到面部。
模型不支持--ref（Jimeng, Seedream 3.0）：创建refs/ref-NN-{slug}.md，包含每个角色的描述（头发、眼镜、肤色、服装）。在提示词文本中嵌入为MUST/REQUIRED指令。
完整决策表参见reference-images.md
步骤2：确认选项 ⚠️
必须使用AskUserQuestion工具以交互式选择呈现选项——而非纯文本表格。在单个AskUserQuestion调用中最多呈现4个问题（类型、调色板、渲染、字体+设置）。每个问题首先显示推荐选项及其理由，然后是备选方案。
