-| `independent` | Use `illustrations/{topic-slug}/`, display "Output: {path}" |
-| Not configured | **MUST** ask with AskUserQuestion ↓ |
-
-**AskUserQuestion** (when no preference):
- `{article-dir}/` - Same directory as article
- `{article-dir}/imgs/` - Images subdirectory
- `{article-dir}/illustrations/` - Illustrations subdirectory (Recommended)
- `illustrations/{topic-slug}/` - Independent directory
- Save as default - Remember this choice for future runs
-
-**1.3 Check Existing Images**
-
-Scan target directory for `.png/.jpg/.webp` files.
-
-If images exist → AskUserQuestion: How to handle?
- `supplement` - Keep existing, generate only new positions
- `overwrite` - Overwrite same-name files
- `regenerate` - Clear all and regenerate
-
-**1.4 Confirm Article Update Method** (file path input only)

+| Purpose | information / visualization / imagination |
+| Core arguments | 2-5 main points |
+| Positions | Where illustrations add value |

-**2.2 Extract Core Arguments**
+**CRITICAL**: Metaphors → visualize underlying concept, NOT literal image.

- Main thesis
- Key concepts reader needs
- Comparisons/contrasts
- Framework/model proposed
-
-**CRITICAL**: If article uses metaphors (e.g., "电锯切西瓜"), do NOT illustrate literally. Visualize the **underlying concept**.
-
-**2.3 Identify Positions**
-
-**Illustrate**:
- Core arguments (REQUIRED)
- Abstract concepts
- Data comparisons
- Processes, workflows
-
-**Do NOT Illustrate**:
- Metaphors literally
- Decorative scenes
- Generic illustrations

 ### Step 3: Confirm Settings ⚠️

-**Do NOT skip.** Use AskUserQuestion with 3-4 questions in ONE call.
+**ONE AskUserQuestion, max 4 Qs. Q1-Q3 REQUIRED.**

-**Q1: Illustration Type**
- [Recommended based on analysis] (Recommended)
- infographic / scene / flowchart / comparison / framework / timeline / mixed
+| Q | Options |
+|---|---------|
+| **Q1: Type** | [Recommended], infographic, scene, flowchart, comparison, framework, timeline, mixed |
+| **Q2: Density** | minimal (1-2), balanced (3-5), per-section (Recommended), rich (6+) |
+| **Q3: Style** | [Recommended], minimal-flat, sci-fi, hand-drawn, editorial, scene, Other |
+| Q4: Language | When article language ≠ EXTEND.md setting |

-**Q2: Density**
- minimal (1-2) - Core concepts only
- balanced (3-5) (Recommended) - Major sections
- rich (6+) - Comprehensive support
-
-**Q3: Style** (ALWAYS ask, even with preferred_style in EXTEND.md)
-
-If EXTEND.md has `preferred_style`:
- [Custom style name + brief description] (Recommended)
- [Top compatible built-in style 1]
- [Top compatible built-in style 2]
- [Top compatible built-in style 3]
-
-If no `preferred_style`:
- [Best compatible from matrix] (Recommended)
- [Other ✓✓ style 1]
- [Other ✓✓ style 2]
- [Other ✓ style]
-
-Style selection based on Type × Style compatibility matrix (references/styles.md).
-Full specs: `references/styles/<style>.md`
-
-**Q4** (only if source ≠ user language):
- Language: Source / User language
-

+Full procedures: [references/workflow.md](references/workflow.md#step-3-confirm-settings-)

 ### Step 4: Generate Outline

-Save as `outline.md`:
+Save `outline.md` with frontmatter (type, density, style, image_count) and entries:

 ```yaml
---
-type: infographic
-density: balanced
-style: blueprint
-image_count: 4
---
-
 ## Illustration 1
-
-**Position**: [section] / [paragraph]
-**Purpose**: [why this helps]
-**Visual Content**: [what to show]
-**Type Application**: [how type applies]
+**Position**: [section/paragraph]
+**Purpose**: [why]
+**Visual Content**: [what]
 **Filename**: 01-infographic-concept-name.png
-
-## Illustration 2
-...
 ```

-**Requirements**:
- Each position justified by content needs
- Type applied consistently
- Style reflected in descriptions
- Count matches density
-

+Full template: [references/workflow.md](references/workflow.md#step-4-generate-outline)

 ### Step 5: Generate Images

-**5.1 Create Prompts**
+⛔ **BLOCKING: Prompt files MUST be saved before ANY image generation.**

-Follow [references/prompt-construction.md](references/prompt-construction.md). Save to `prompts/illustration-{slug}.md`.
+1. For each illustration, create a prompt file per [references/prompt-construction.md](references/prompt-construction.md)
+2. Save to `prompts/NN-{type}-{slug}.md` with YAML frontmatter
+3. Prompts **MUST** use type-specific templates with structured sections (ZONES / LABELS / COLORS / STYLE / ASPECT)
+4. LABELS **MUST** include article-specific data: actual numbers, terms, metrics, quotes
+5. **DO NOT** pass ad-hoc inline prompts to `--prompt` without saving prompt files first
+6. Select generation skill, process references (`direct`/`style`/`palette`)
+7. Apply watermark if EXTEND.md enabled
+8. Generate from saved prompt files; retry once on failure

-**5.2 Select Generation Skill**
-
-Check available skills. If multiple, ask user.
-
-**5.3 Apply Watermark** (if enabled)
-
-Add: `Include a subtle watermark "[content]" at [position].`
-
-**5.4 Generate**
-
-1. Generate sequentially
-2. After each: "Generated X/N"
-3. On failure: retry once, then log and continue
-

+Full procedures: [references/workflow.md](references/workflow.md#step-5-generate-images)

 ### Step 6: Finalize

-**6.1 Update Article**
-
-Insert after corresponding paragraph:
-```markdown
-![description](illustrations/{slug}/NN-{type}-{slug}.png)
-```
-
-Alt text: concise description in article's language.
-
-**6.2 Output Summary**
+Insert `![description](path/NN-{type}-{slug}.png)` after paragraphs.

 # Prompt Construction

+## Prompt File Format
+
+Each prompt file uses YAML frontmatter + content:
+
+```yaml
+---
+illustration_id: 01
+type: infographic
+style: blueprint
+references:                    # ⚠️ ONLY if files EXIST in references/ directory
+  - ref_id: 01

+    usage: direct              # direct | style | palette
+---
+
+[Type-specific template content below...]
+```
+
+**⚠️ CRITICAL - When to include `references` field**:
+
+| Situation | Action |
+|-----------|--------|
+| Reference file saved to `references/` | Include in frontmatter ✓ |
+| Style extracted verbally (no file) | DO NOT include in frontmatter, append to prompt body instead |
+| File path in frontmatter but file doesn't exist | ERROR - remove references field |
+
+**Reference Usage Types** (only when file exists):
+
+| Usage | Description | Generation Action |
+|-------|-------------|-------------------|
+| `direct` | Primary visual reference | Pass to `--ref` parameter |
+| `style` | Style characteristics only | Describe style in prompt text |
+| `palette` | Color palette extraction | Include colors in prompt |

+- Secondary: #7ECFC0 mint
+...
+
+STYLE (from reference):
+- Clean lines, minimal shadows
+- Gradient backgrounds
+...
+```
+

+
+## Default Composition Requirements
+
+**Apply to ALL prompts by default**:
+
+| Requirement | Description |
+|-------------|-------------|
+| **Clean composition** | Simple layouts, no visual clutter |
+| **White space** | Generous margins, breathing room around elements |
+| **No complex backgrounds** | Solid colors or subtle gradients only, avoid busy textures |
+| **Centered or content-appropriate** | Main visual elements centered or positioned by content needs |
+| **Matching graphics** | Use graphic elements that align with content theme |
+| **Highlight core info** | White space draws attention to key information |
+
+**Add to ALL prompts**:
+> Clean composition with generous white space. Simple or no background. Main elements centered or positioned by content needs.
+
+---
+
+## Character Rendering
+
+When depicting people:
+
+| Guideline | Description |
+|-----------|-------------|
+| **Style** | Simplified cartoon silhouettes or symbolic expressions |
+| **Avoid** | Realistic human portrayals, detailed faces |
+| **Diversity** | Varied body types when showing multiple people |
+| **Emotion** | Express through posture and simple gestures |
+
+**Add to ALL prompts with human figures**:
+> Human figures: simplified stylized silhouettes or symbolic representations, not photorealistic.
+
+---
+
+## Text in Illustrations
+
+| Element | Guideline |
+|---------|-----------|
+| **Size** | Large, prominent, immediately readable |
+| **Style** | Handwritten fonts preferred for warmth |
+| **Content** | Concise keywords and core concepts only |
+| **Language** | Match article language |
+
+**Add to prompts with text**:
+> Text should be large and prominent with handwritten-style fonts. Keep minimal, focus on keywords.

+# Detailed Workflow Procedures
+
+## Step 1: Pre-check
+
+### 1.0 Detect & Save Reference Images ⚠️ REQUIRED if images provided
+
+Check if user provided reference images. Handle based on input type:
+
+| Input Type | Action |
+|------------|--------|
+| Image file path provided | Copy to `references/` subdirectory → can use `--ref` |
+| Image in conversation (no path) | **ASK user for file path** with AskUserQuestion |
+| User can't provide path | Extract style/palette verbally → append to prompts (NO frontmatter references) |
+
+**CRITICAL**: Only add `references` to prompt frontmatter if files are ACTUALLY SAVED to `references/` directory.
+
+**If user provides file path**:
+1. Copy to `references/NN-ref-{slug}.png`
+2. Create description: `references/NN-ref-{slug}.md`
+3. Verify files exist before proceeding
+
+**If user can't provide path** (extracted verbally):
+1. Analyze image visually, extract: colors, style, composition
+2. Create `references/extracted-style.md` with extracted info
+3. DO NOT add `references` to prompt frontmatter
+4. Instead, append extracted style/colors directly to prompt text
+
+**Description File Format** (only when file saved):
+```yaml
+---
+ref_id: NN
+filename: NN-ref-{slug}.png
+---
+[User's description or auto-generated description]
+```
+
+**Verification** (only for saved files):
+```
+Reference Images Saved:
+- 01-ref-{slug}.png ✓ (can use --ref)
+- 02-ref-{slug}.png ✓ (can use --ref)
+```
+
+**Or for extracted style**:
+```
+Reference Style Extracted (no file):
+- Colors: #E8756D coral, #7ECFC0 mint...
+- Style: minimal flat vector, clean lines...
+→ Will append to prompt text (not --ref)
+```
+
+---
+
+### 1.1 Determine Input Type
+
+| Input | Output Directory | Next |
+|-------|------------------|------|
+| File path | Ask user (1.2) | → 1.2 |
+| Pasted content | `illustrations/{topic-slug}/` | → 1.4 |
+
+**Backup rule for pasted content**: If `source.md` exists in target directory, rename to `source-backup-YYYYMMDD-HHMMSS.md` before saving.
+
+### 1.2-1.4 Configuration (file path input only)
+
+Check preferences and existing state, then ask ALL needed questions in ONE AskUserQuestion call (max 4 questions).
+
+**Questions to include** (skip if preference exists or not applicable):
+
+| Question | When to Ask | Options |
+|----------|-------------|---------|
+| Output directory | No `default_output_dir` in EXTEND.md | `{article-dir}/`, `{article-dir}/imgs/` (Recommended), `{article-dir}/illustrations/`, `illustrations/{topic-slug}/` |
+| Existing images | Target dir has `.png/.jpg/.webp` files | `supplement`, `overwrite`, `regenerate` |
+| Article update | Always (file path input) | `update`, `copy` |
+
+**Preference Values** (if configured, skip asking):
+
+| `default_output_dir` | Path |
+|----------------------|------|
+| `same-dir` | `{article-dir}/` |
+| `imgs-subdir` | `{article-dir}/imgs/` |
+| `illustrations-subdir` | `{article-dir}/illustrations/` |
+| `independent` | `illustrations/{topic-slug}/` |
+
+### 1.5 Load Preferences (EXTEND.md) ⛔ BLOCKING
+
+**CRITICAL**: If EXTEND.md not found, MUST complete first-time setup before ANY other questions or steps. Do NOT proceed to reference images, do NOT ask about content, do NOT ask about type/style — ONLY complete the preferences setup first.
+
+```bash
+test -f .baoyu-skills/baoyu-article-illustrator/EXTEND.md && echo "project"
+test -f "$HOME/.baoyu-skills/baoyu-article-illustrator/EXTEND.md" && echo "user"
+```
+
+| Result | Action |
+|--------|--------|
+| Found | Read, parse, display summary → Continue |
+| Not found | ⛔ **BLOCKING**: Run first-time setup ONLY ([config/first-time-setup.md](config/first-time-setup.md)) → Complete and save EXTEND.md → Then continue |
+
+**Supports**: Watermark | Preferred type/style | Custom styles | Language | Output directory
+
+---
+
+## Step 2: Setup & Analyze
+
+### 2.1 Analyze Content
+
+| Analysis | Description |
+|----------|-------------|
+| Content type | Technical / Tutorial / Methodology / Narrative |
+| Illustration purpose | information / visualization / imagination |
+| Core arguments | 2-5 main points to visualize |
+| Visual opportunities | Positions where illustrations add value |
+| Recommended type | Based on content signals and purpose |
+| Recommended density | Based on length and complexity |
+
+### 2.2 Extract Core Arguments
+
+- Main thesis
+- Key concepts reader needs
+- Comparisons/contrasts
+- Framework/model proposed
+
+**CRITICAL**: If article uses metaphors (e.g., "电锯切西瓜"), do NOT illustrate literally. Visualize the **underlying concept**.
+
+### 2.3 Identify Positions
+
+**Illustrate**:
+- Core arguments (REQUIRED)
+- Abstract concepts
+- Data comparisons
+- Processes, workflows
+
+**Do NOT Illustrate**:
+- Metaphors literally
+- Decorative scenes
+- Generic illustrations
+
+### 2.4 Analyze Reference Images (if provided in Step 1.0)
+
+For each reference image:
+
+| Analysis | Description |
+|----------|-------------|
+| Visual characteristics | Style, colors, composition |
+| Content/subject | What the reference depicts |
+| Suitable positions | Which sections match this reference |
+| Style match | Which illustration types/styles align |
+| Usage recommendation | `direct` / `style` / `palette` |
+
+| Usage | When to Use |
+|-------|-------------|
+| `direct` | Reference matches desired output closely |
+| `style` | Extract visual style characteristics only |
+| `palette` | Extract color scheme only |
+
+---
+
+## Step 3: Confirm Settings ⚠️
+
+**Do NOT skip.** Use ONE AskUserQuestion call with max 4 questions. **Q1, Q2, Q3 are ALL REQUIRED.**
+
+### Q1: Illustration Type ⚠️ REQUIRED
+- [Recommended based on analysis] (Recommended)
+- infographic / scene / flowchart / comparison / framework / timeline / mixed
+
+### Q2: Density ⚠️ REQUIRED - DO NOT SKIP
+- minimal (1-2) - Core concepts only
+- balanced (3-5) - Major sections
+- per-section - At least 1 per section/chapter (Recommended)
+- rich (6+) - Comprehensive coverage
+
+### Q3: Style ⚠️ REQUIRED (ALWAYS ask, even with preferred_style in EXTEND.md)
+
+If EXTEND.md has `preferred_style`:
+- [Custom style name + brief description] (Recommended)

+### Q4: Image Text Language ⚠️ REQUIRED when article language ≠ EXTEND.md `language`
+
+Detect article language from content. If different from EXTEND.md `language` setting, MUST ask:
+- Article language (match article content) (Recommended)
+- EXTEND.md language (user's general preference)
+
+**Skip only if**: Article language matches EXTEND.md `language`, or EXTEND.md has no `language` setting.
+
+### Display Reference Usage (if references detected in Step 1.0)
+
+When presenting outline preview to user, show reference assignments:
+
+```
+Reference Images:
+| Ref | Filename | Recommended Usage |
+|-----|----------|-------------------|
+| 01 | 01-ref-diagram.png | direct → Illustration 1, 3 |
+| 02 | 02-ref-chart.png | palette → Illustration 2 |
+```
+
+---
+
+## Step 4: Generate Outline
+
+Save as `outline.md`:
+
+```yaml
+---
+type: infographic
+density: balanced
+style: blueprint
+image_count: 4
+references:                    # Only if references provided
+  - ref_id: 01
+    filename: 01-ref-diagram.png
+    description: "Technical diagram showing system architecture"
+  - ref_id: 02
+    filename: 02-ref-chart.png
+    description: "Color chart with brand palette"
+---
+
+## Illustration 1
+
+**Position**: [section] / [paragraph]
+**Purpose**: [why this helps]
+**Visual Content**: [what to show]
+**Type Application**: [how type applies]
+**References**: [01]                    # Optional: list ref_ids used
+**Reference Usage**: direct             # direct | style | palette
+**Filename**: 01-infographic-concept-name.png
+
+## Illustration 2
+...
+```
+
+**Requirements**:
+- Each position justified by content needs
+- Type applied consistently
+- Style reflected in descriptions
+- Count matches density
+- References assigned based on Step 2.4 analysis
+
+---
+
+## Step 5: Generate Images
+
+### 5.1 Create Prompts ⛔ BLOCKING
+
+**Every illustration MUST have a saved prompt file before generation begins. DO NOT skip this step.**
+
+For each illustration in the outline:
+
+1. **Create prompt file**: `prompts/NN-{type}-{slug}.md`
+2. **Include YAML frontmatter**:
+   ```yaml
+   ---
+   illustration_id: 01
+   type: infographic
+   style: custom-flat-vector
+   ---
+   ```
+3. **Follow type-specific template** from [prompt-construction.md](prompt-construction.md)
+4. **Prompt quality requirements** (all REQUIRED):
+   - `Layout`: Describe overall composition (grid / radial / hierarchical / left-right / top-down)
+   - `ZONES`: Describe each visual area with specific content, not vague descriptions
+   - `LABELS`: Use **actual numbers, terms, metrics, quotes from the article** — NOT generic placeholders
+   - `COLORS`: Specify hex codes with semantic meaning (e.g., `Coral (#E07A5F) for emphasis`)
+   - `STYLE`: Describe line treatment, texture, mood, character rendering
+   - `ASPECT`: Specify ratio (e.g., `16:9`)
+5. **Apply defaults**: composition requirements, character rendering, text guidelines, watermark
+6. **Backup rule**: If prompt file exists, rename to `prompts/NN-{type}-{slug}-backup-YYYYMMDD-HHMMSS.md`
+
+**Verification** ⛔: Before proceeding to 5.2, confirm ALL prompt files exist:
+```
+Prompt Files:
+- prompts/01-infographic-overview.md ✓
+- prompts/02-infographic-distillation.md ✓
+...
+```
+
+**DO NOT** pass ad-hoc inline text to `--prompt` without first saving prompt files. The generation command should either use `--promptfiles prompts/NN-{type}-{slug}.md` or read the saved file content for `--prompt`.
+
+**CRITICAL - References in Frontmatter**:
+- Only add `references` field if files ACTUALLY EXIST in `references/` directory
+- If style/palette was extracted verbally (no file), append info to prompt BODY instead
+- Before writing frontmatter, verify: `test -f references/NN-ref-{slug}.png`
+
+### 5.2 Select Generation Skill
+
+Check available skills. If multiple, ask user.
+
+### 5.3 Process References ⚠️ REQUIRED if references saved in Step 1.0
+
+**DO NOT SKIP if user provided reference images.** For each illustration with references:
+
+1. **VERIFY files exist first**:
+   ```bash
+   test -f references/NN-ref-{slug}.png && echo "exists" || echo "MISSING"
+   ```
+   - If file MISSING but in frontmatter → ERROR, fix frontmatter or remove references field
+   - If file exists → proceed with processing
+
+2. Read prompt frontmatter for reference info
+3. Process based on usage type:
+
+| Usage | Action | Example |
+|-------|--------|---------|
+| `direct` | Add reference path to `--ref` parameter | `--ref references/01-ref-brand.png` |
+| `style` | Analyze reference, append style traits to prompt | "Style: clean lines, gradient backgrounds..." |
+| `palette` | Extract colors from reference, append to prompt | "Colors: #E8756D coral, #7ECFC0 mint..." |
+
+4. Check image generation skill capability:
+
+| Skill Supports `--ref` | Action |
+|------------------------|--------|
+| Yes (e.g., baoyu-image-gen with Google) | Pass reference images via `--ref` |
+| No | Convert to text description, append to prompt |
+
+**Verification**: Before generating, confirm reference processing:
+```
+Reference Processing:
+- Illustration 1: using 01-ref-brand.png (direct) ✓
+- Illustration 2: extracted palette from 02-ref-style.png ✓
+```
+
+### 5.4 Apply Watermark (if enabled)
+
+Add: `Include a subtle watermark "[content]" at [position].`
+
+### 5.5 Generate
+
+1. For each illustration:
+   - **Backup rule**: If image file exists, rename to `NN-{type}-{slug}-backup-YYYYMMDD-HHMMSS.md`
+   - If references with `direct` usage: include `--ref` parameter
+   - Generate image
+2. After each: "Generated X/N"
+3. On failure: retry once, then log and continue
+
+---
+
+## Step 6: Finalize
+
+### 6.1 Update Article
+
+Insert after corresponding paragraph:
+```markdown
+![description](illustrations/{slug}/NN-{type}-{slug}.png)
+```
+
+Alt text: concise description in article's language.

 ### Step 1: Analyze Content

-1. **Save source content** (if pasted, save to `source.md` in target directory; if file path, use as-is)
-2. **Content analysis**: Extract topic, core message, tone, keywords; identify visual metaphors; detect content type
-3. **Language detection**: Detect source language, note user's input language, compare with EXTEND.md preference
-4. **Determine output directory** per File Structure rules. If no `default_output_dir` preference + file path input, include in Step 2 Q4
+1. **Save reference images** (if provided) → [references/workflow/reference-images.md](references/workflow/reference-images.md)
+2. **Save source content** (if pasted, save to `source.md`)

+4. **Deep analyze references** ⚠️: Extract specific, concrete elements (see reference-images.md)
+5. **Detect language**: Compare source, user input, EXTEND.md preference

+## Composition Principles

-## Notes
+- **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

- Cover must be readable at small preview sizes
- Visual metaphors > literal representations
- Title: max 8 chars, readable, impactful
- Two confirmation points: Step 0 (first-time setup) + Step 2 (options) - skip Step 2 with `--quick`
- Use confirmed language for title text
- Maintain watermark consistency if enabled
- Check compatibility matrices when selecting combinations
- `--no-title` is alias for `--text none`
- `--style` presets are backward-compatible; explicit `--palette`/`--rendering` override preset values
+## Extension Support

+Custom configurations via EXTEND.md. See **Step 0** for paths.

+## Reference Image Handling
+
+When user provides reference images (`--ref` or pasted images):
+
+### ⚠️ CRITICAL - Frontmatter References
+
+**MUST add `references` field in YAML frontmatter** when reference files are saved to `refs/`:
+
+```yaml
+---
+type: cover
+palette: warm
+rendering: flat-vector
+references:
+  - ref_id: 01
+    filename: refs/ref-01-podcast-thumbnail.jpg
+    usage: style
+---
+```
+
+| Field | Description |
+|-------|-------------|
+| `ref_id` | Sequential number (01, 02, ...) |
+| `filename` | Relative path from prompt file's parent directory |
+| `usage` | `direct` / `style` / `palette` |
+
+**Omit `references` field entirely** if no reference files saved (style extracted verbally only).
+
+### When to Include References in Frontmatter
+
+| Situation | Frontmatter Action | Generation Action |
+|-----------|-------------------|-------------------|
+| Reference file saved to `refs/` | Add to `references` list ✓ | Pass via `--ref` parameter |
+| Style extracted verbally (no file) | Omit `references` field | Describe in prompt body only |
+| File path in frontmatter but doesn't exist | ERROR - fix or remove | Generation will fail |
+
+**Before writing prompt with references, verify**: `test -f refs/ref-NN-{slug}.{ext}`
+
+### Reference Usage Types
+
+| Usage | When to Use | Generation Action |
+|-------|-------------|-------------------|
+| `direct` | Reference matches desired output closely | Pass to `--ref` parameter |
+| `style` | Extract visual style characteristics only | Describe style in prompt text |
+| `palette` | Extract color palette only | Include colors in prompt |
+
+### Step 1: Analyze References
+
+For each reference image, extract:
+- **Style**: Rendering technique, line quality, texture
+- **Composition**: Layout, visual hierarchy, focal points
+- **Color mood**: Palette characteristics (without specific colors)
+- **Elements**: Key visual elements and symbols used
+
+### Step 2: Embed in Prompt ⚠️ CRITICAL
+
+**Passing `--ref` alone is NOT enough.** Image generation models frequently ignore reference images unless the prompt text explicitly and forcefully describes what to reproduce. You MUST always write detailed textual instructions regardless of whether `--ref` is used.
+
+**If file saved (with or without `--ref` support)**:
+- Pass ref images via `--ref` parameter if skill supports it
+- **ALWAYS** add a detailed mandatory section in the prompt body:
+
+```
+# Reference Style — MUST INCORPORATE
+
+CRITICAL: The generated cover MUST visually reference the provided images. The cover must feel like it belongs to the same visual family.
+
+## From Ref 1 ([filename]) — REQUIRED elements:
+- [Brand element]: [Specific description of logo/wordmark treatment, e.g., "The logo uses vertical parallel lines (|||) for the letter 'm'. Reproduce this exact treatment."]
+- [Signature pattern]: [Specific description, e.g., "Woven intersecting curves forming a diamond/lozenge grid pattern. This MUST appear prominently as a banner, border, or background section."]
+- [Colors]: [Exact hex values, e.g., "Dark teal #2D4A3E background, cream #F5F0E0 text"]
+- [Typography]: [Specific treatment, e.g., "Uppercase text with wide letter-spacing"]
+- [Layout element]: [Specific spatial element, e.g., "Bottom banner strip in dark color"]
+
+## From Ref 2 ([filename]) — REQUIRED elements:
+[Same detailed breakdown]
+
+## Integration approach:
+[Specific layout instruction describing how reference elements combine with the cover content, e.g., "Use a SPLIT LAYOUT: main illustration area (warm cream background) occupies ~65% of the image, while a dark teal BANNER STRIP (with the woven line pattern from Ref 2) runs along the bottom ~35%, containing branding elements from Ref 1."]
+```
+
+**Key rules**:
+- Each visual element gets its own bullet with "MUST" or "REQUIRED"
+- Descriptions must be **specific enough to reproduce** — not vague ("clean style")
+- The integration approach must describe **exact spatial arrangement**
+- After generation, verify reference elements are visible; if not, strengthen and regenerate
+
+**If style/palette extracted verbally (NO file saved)**:
+- DO NOT add references metadata to prompt
+- Append extracted info directly to prompt body using the same MUST INCORPORATE format above:
+
+```
+# Reference Style — MUST INCORPORATE (extracted from visual analysis)
+
+CRITICAL: Apply these specific visual elements extracted from the reference images.
+
+## REQUIRED elements:
+- [Same detailed bullet format as above]
+
+## Integration approach:
+[Same spatial layout instruction]
+```
+
+### Reference Analysis Template
+
+Use this format when analyzing reference images. Extract **specific, concrete, reproducible** details — not vague summaries.
+
+| Aspect | Analysis Points | Good Example | Bad Example |
+|--------|-----------------|--------------|-------------|
+| **Brand elements** | Logos, wordmarks, distinctive typography | "Logo 'm' formed by 3 vertical lines" | "Has a logo" |
+| **Signature patterns** | Unique motifs, textures, geometric patterns | "Woven curves forming diamond grid" | "Has patterns" |
+| **Colors** | Exact hex values or close approximations | "#2D4A3E dark teal, #F5F0E0 cream" | "Dark and light" |
+| **Layout** | Spatial zones, banner placement, proportions | "Bottom 30% is dark banner with branding" | "Has a banner" |
+| **Typography** | Font style, weight, case, spacing, position | "Uppercase, wide letter-spacing, right-aligned" | "Has text" |
+| **Rendering** | Line quality, texture, depth treatment | "Topographic contour lines as background texture" | "Clean style" |
+| **Elements** | Icon vocabulary, decorative motifs | "Geometric intersecting line ornaments at corners" | "Has decorations" |
+
+**Output**: Each extracted element should be written as a **copy-pasteable prompt instruction** prefixed with "MUST" or "REQUIRED".

+# Reference Image Handling
+
+Guide for processing user-provided reference images in cover generation.
+
+## Input Detection
+
+| Input Type | Action |
+|------------|--------|
+| Image file path provided | Copy to `refs/` → can use `--ref` |
+| Image in conversation (no path) | **ASK user for file path** with AskUserQuestion |
+| User can't provide path | Extract style/palette verbally → append to prompt (NO frontmatter references) |
+
+**CRITICAL**: Only add `references` to prompt frontmatter if files are ACTUALLY SAVED to `refs/` directory.
+
+## File Saving
+
+**If user provides file path**:
+1. Copy to `refs/ref-NN-{slug}.{ext}` (NN = 01, 02, ...)
+2. Create description: `refs/ref-NN-{slug}.md`
+3. Verify files exist before proceeding
+
+**Description File Format**:
+```yaml
+---
+ref_id: NN
+filename: ref-NN-{slug}.{ext}
+usage: direct | style | palette
+---
+[User's description or auto-generated description]
+```
+
+| Usage | When to Use |
+|-------|-------------|
+| `direct` | Reference matches desired output closely |
+| `style` | Extract visual style characteristics only |
+| `palette` | Extract color scheme only |
+
+## Verbal Extraction (No File)
+
+When user can't provide file path:
+1. Analyze image visually, extract: colors, style, composition
+2. Create `refs/extracted-style.md` with extracted info
+3. DO NOT add `references` to prompt frontmatter
+4. Append extracted style/colors directly to prompt text
+
+## Deep Analysis ⚠️ CRITICAL
+
+References are high-priority inputs. Extract **specific, concrete, reproducible** elements:
+
+| Analysis | Description | Example (good vs bad) |
+|----------|-------------|----------------------|
+| **Brand elements** | Logos, wordmarks, specific typography | Good: "Logo uses vertical parallel lines for 'm'" / Bad: "Has a logo" |
+| **Signature patterns** | Unique decorative motifs, textures | Good: "Woven intersecting curves forming diamond grid" / Bad: "Has patterns" |
+| **Color palette** | Exact hex values for key colors | Good: "#2D4A3E dark teal, #F5F0E0 cream" / Bad: "Dark and light colors" |
+| **Layout structure** | Specific spatial arrangement | Good: "Bottom 30% dark banner with branding" / Bad: "Has a banner" |
+| **Typography** | Font style, weight, spacing, case | Good: "Uppercase, wide letter-spacing" / Bad: "Has text" |
+| **Content/subject** | What the reference depicts | Factual description |
+| **Usage recommendation** | `direct` / `style` / `palette` | Based on analysis |
+
+**Output format**: List each element as bullet that can be copy-pasted into prompt as mandatory instruction.
+
+## Verification Output
+
+**For saved files**:
+```
+Reference Images Saved:
+- ref-01-{slug}.png ✓ (can use --ref)
+- ref-02-{slug}.png ✓ (can use --ref)
+```
+
+**For extracted style**:
+```
+Reference Style Extracted (no file):
+- Colors: #E8756D coral, #7ECFC0 mint...
+- Style: minimal flat vector, clean lines...
+→ Will append to prompt text (not --ref)
+```
+
+## Priority Rules
+
+When user provides references, they are **HIGH PRIORITY**:
+
+- **References override defaults**: If reference conflicts with preferred palette/rendering, reference takes precedence
+- **Concrete > abstract**: Extract specific elements — not vague "clean style"
+- **Mandatory language**: Use "MUST", "REQUIRED" in prompt for reference elements
+- **Visible in output**: Verify elements are present after generation; strengthen prompt if not

+3. **If no remote media found** → done, no prompt needed
+4. **If remote media found** → use `AskUserQuestion`:
+   - header: "Media", question: "Download N images/videos to local files?"
+   - "Yes" — Download to local directories
+   - "No" — Keep remote URLs
+5. If user confirms → run script **again** with `--download-media` (overwrites markdown with localized links)

+
+# First-Time Setup
+
+## Overview
+
+When no EXTEND.md is found, guide user through preference setup.
+
+**BLOCKING OPERATION**: This setup MUST complete before ANY other workflow steps. Do NOT:
+- Start converting tweets or articles
+- Ask about URLs or output paths
+- Proceed to any conversion
+
+ONLY ask the questions in this setup flow, save EXTEND.md, then continue.
+
+## Setup Flow
+
+```
+No EXTEND.md found
+        |
+        v
+---------------------+
+| AskUserQuestion     |
+| (all questions)     |
+---------------------+
+        |
+        v
+---------------------+
+| Create EXTEND.md    |
+---------------------+
+        |
+        v
+    Continue conversion
+```
+
+## Questions
+
+**Language**: Use user's input language or saved language preference.
+
+Use AskUserQuestion with ALL questions in ONE call:
+
+### Question 1: Download Media
+
+```yaml
+header: "Media"
+question: "How to handle images and videos in tweets?"
+options:
+  - label: "Ask each time (Recommended)"
+    description: "After saving markdown, ask whether to download media"
+  - label: "Always download"
+    description: "Always download media to local imgs/ and videos/ directories"
+  - label: "Never download"
+    description: "Keep original remote URLs in markdown"
+```
+
+### Question 2: Default Output Directory
+
+```yaml
+header: "Output"
+question: "Default output directory?"
+options:
+  - label: "x-to-markdown (Recommended)"
+    description: "Save to ./x-to-markdown/{username}/{tweet-id}.md"
+```
+
+Note: User will likely choose "Other" to type a custom path.
+
+### Question 3: Save Location
+
+```yaml
+header: "Save"
+question: "Where to save preferences?"
+options:
+  - label: "User (Recommended)"
+    description: "~/.baoyu-skills/ (all projects)"
+  - label: "Project"
+    description: ".baoyu-skills/ (this project only)"
+```
+
+## Save Locations
+
+| Choice | Path | Scope |
+|--------|------|-------|
+| User | `~/.baoyu-skills/baoyu-danger-x-to-markdown/EXTEND.md` | All projects |
+| Project | `.baoyu-skills/baoyu-danger-x-to-markdown/EXTEND.md` | Current project |
+
+## After Setup
+
+1. Create directory if needed
+2. Write EXTEND.md
+3. Confirm: "Preferences saved to [path]"
+4. Continue with conversion using saved preferences
+
+## EXTEND.md Template
+
+```md
+download_media: [ask/1/0]
+default_output_dir: [path or empty]
+```
+
+## Modifying Preferences Later
+
+Users can edit EXTEND.md directly or delete it to trigger setup again.

+description: Formats plain text or markdown files with frontmatter, titles, summaries, headings, bold, lists, and code blocks. Use when user asks to "format markdown", "beautify article", "add formatting", or improve article layout. Outputs to {filename}-formatted.md.
+---
+
+# Markdown Formatter
+
+Transforms plain text or markdown files into well-structured markdown with proper frontmatter, formatting, and typography.
+
+## Script Directory
+
+Scripts in `scripts/` subdirectory. Replace `${SKILL_DIR}` with this SKILL.md's directory path.
+
+| Script | Purpose |
+|--------|---------|
+| `scripts/main.ts` | Main entry point with CLI options (uses remark-cjk-friendly for CJK emphasis) |
+| `scripts/quotes.ts` | Replace ASCII quotes with fullwidth quotes |
+| `scripts/autocorrect.ts` | Add CJK/English spacing via autocorrect |
+
+## Preferences (EXTEND.md)
+
+Use Bash to check EXTEND.md existence (priority order):
+
+```bash
+# Check project-level first
+test -f .baoyu-skills/baoyu-format-markdown/EXTEND.md && echo "project"
+
+# Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)
+test -f "$HOME/.baoyu-skills/baoyu-format-markdown/EXTEND.md" && echo "user"
+```

+
+## Usage
+
+Claude performs content analysis and formatting (Steps 1-6), then runs the script for typography fixes (Step 7).
+
+## Workflow
+
+### Step 1: Read Source File
+
+Read the user-specified markdown or plain text file.
+
+### Step 1.5: Detect Content Type & Confirm
+
+**Content Type Detection:**
+
+| Indicator | Classification |
+|-----------|----------------|
+| Has `---` YAML frontmatter | Markdown |
+| Has `#`, `##`, `###` headings | Markdown |
+| Has `**bold**`, `*italic*` | Markdown |
+| Has `- ` or `1. ` lists | Markdown |
+| Has ``` code blocks | Markdown |
+| Has `> ` blockquotes | Markdown |
+| None of above | Plain text |
+
+**Decision Flow:**
+
+┌─────────────────┬────────────────────────────────────────────────┐
+│  Content Type   │                     Action                     │
+├─────────────────┼────────────────────────────────────────────────┤
+│ Plain text      │ Proceed to Step 2 (format to markdown)         │
+├─────────────────┼────────────────────────────────────────────────┤
+│ Markdown        │ Use AskUserQuestion to confirm optimization    │
+└─────────────────┴────────────────────────────────────────────────┘
+
+**If Markdown detected, ask user:**
+
+```
+Detected existing markdown formatting. What would you like to do?
+
+1. Optimize formatting (Recommended)
+   - Add/improve frontmatter, headings, bold, lists
+   - Run typography script (spacing, emphasis fixes)
+   - Output: {filename}-formatted.md
+
+2. Keep original formatting
+   - Preserve existing markdown structure
+   - Run typography script (spacing, emphasis fixes)
+   - Output: {filename}-formatted.md
+
+3. Typography fixes only
+   - Run typography script on original file in-place
+   - No copy created, modifies original file directly
+```
+
+**Based on user choice:**
+- **Optimize**: Continue to Step 2-8 (full workflow)
+- **Keep original**: Skip Steps 2-5, copy file → Step 6-8 (run script on copy)
+- **Typography only**: Skip Steps 2-6, run Step 7 on original file directly
+
+### Step 2: Analyze Content Structure
+
+Identify:
+- Existing title (H1 `#`)
+- Paragraph separations
+- Keywords suitable for **bold**
+- Parallel content convertible to lists
+- Code snippets
+- Quotations
+
+### Step 3: Check/Create Frontmatter
+
+Check for YAML frontmatter (`---` block). Create if missing.
+
+**Meta field handling:**
+
+| Field | Processing |
+|-------|------------|
+| `title` | See Step 4 |
+| `slug` | Infer from file path (e.g., `posts/2026/01/10/vibe-coding/` → `vibe-coding`) or generate from title |
+| `summary` | Generate engaging summary (100-150 characters) |
+| `coverImage` | Check if `imgs/cover.png` exists in same directory; if so, use relative path (also accepted: `featureImage`) |
+
+### Step 4: Title Handling
+
+**Logic:**
+1. If frontmatter already has `title` → use it, no H1 in body
+2. If first line is H1 → extract to frontmatter `title`, remove H1 from body
+3. If neither exists → generate candidate titles
+
+**Title generation flow:**
+
+1. Generate 3 candidate titles based on content
+2. Use `AskUserQuestion` tool:
+
+```
+Select a title:
+
+1. [Title A] (Recommended)
+2. [Title B]
+3. [Title C]
+```
+
+3. If no selection within a few seconds, use recommended (option 1)
+
+**Title principles:**
+- Concise, max 20 characters
+- Captures core message
+- Engaging, sparks reading interest
+- Accurate, avoids clickbait
+
+**Important:** Once title is in frontmatter, body should NOT have H1 (avoid duplication)
+
+### Step 5: Format Processing
+
+**Formatting rules:**
+
+| Element | Format |
+|---------|--------|
+| Titles | Use `#`, `##`, `###` hierarchy |
+| Key points | Use `**bold**` |
+| Parallel items | Convert to `-` unordered or `1.` ordered lists |
+| Code/commands | Use `` `inline` `` or ` ```block``` ` |
+| Quotes/sayings | Use `>` blockquote |
+| Separators | Use `---` where appropriate |
+
+**Formatting principles:**
+- Preserve original content and viewpoints
+- Add formatting only, do not modify text
+- Formatting serves readability
+- Avoid over-formatting
+
+### Step 6: Save Formatted File
+
+Save as `{original-filename}-formatted.md`
+
+Examples:
+- `final.md` → `final-formatted.md`
+- `draft-v1.md` → `draft-v1-formatted.md`
+
+**If user chose "Keep original formatting" (from Step 1.5):**
+- Copy original file to `{filename}-formatted.md` without modifications
+- Proceed to Step 7 for typography fixes only
+
+**Backup existing file:**
+
+If `{filename}-formatted.md` already exists, backup before overwriting:
+
+```bash
+# Check if formatted file exists
+if [ -f "{filename}-formatted.md" ]; then
+  # Backup with timestamp
+  mv "{filename}-formatted.md" "{filename}-formatted.backup-$(date +%Y%m%d-%H%M%S).md"
+fi
+```
+
+Example:
+- `final-formatted.md` exists → backup to `final-formatted.backup-20260128-143052.md`
+
+### Step 7: Execute Text Formatting Script
+
+After saving, **must** run the formatting script:
+
+```bash
+npx -y bun ${SKILL_DIR}/scripts/main.ts {output-file-path} [options]
+```
+
+**Script Options:**
+
+| Option | Short | Description | Default |
+|--------|-------|-------------|---------|
+| `--quotes` | `-q` | Replace ASCII quotes with fullwidth quotes `"..."` | false |
+| `--no-quotes` | | Do not replace quotes | |
+| `--spacing` | `-s` | Add CJK/English spacing via autocorrect | true |
+| `--no-spacing` | | Do not add CJK/English spacing | |
+| `--emphasis` | `-e` | Fix CJK emphasis punctuation issues | true |
+| `--no-emphasis` | | Do not fix CJK emphasis issues | |
+| `--help` | `-h` | Show help message | |
+
+**Examples:**
+
+```bash
+# Default: spacing + emphasis enabled, quotes disabled
+npx -y bun ${SKILL_DIR}/scripts/main.ts article.md
+
+# Enable all features including quote replacement
+npx -y bun ${SKILL_DIR}/scripts/main.ts article.md --quotes
+
+# Only fix emphasis issues, skip spacing
+npx -y bun ${SKILL_DIR}/scripts/main.ts article.md --no-spacing
+
+# Disable all processing except frontmatter formatting
+npx -y bun ${SKILL_DIR}/scripts/main.ts article.md --no-spacing --no-emphasis
+```
+
+**Script performs (based on options):**
+1. Fix CJK emphasis/bold punctuation issues (default: enabled)
+2. Add CJK/English mixed text spacing via autocorrect (default: enabled)
+3. Replace ASCII quotes `"..."` with fullwidth quotes `"..."` (default: disabled)
+4. Format frontmatter YAML (always enabled)
+
+### Step 8: Display Results
+
+```
+**Formatting complete**
+
+File: posts/2026/01/09/example/final-formatted.md
+
+Changes:
+- Added title: [title content]
+- Added X bold markers
+- Added X lists
+- Added X code blocks
+```
+
+## Formatting Example
+
+**Before:**
+```
+This is plain text. First point is efficiency improvement. Second point is cost reduction. Third point is experience optimization. Use npm install to install dependencies.
+```
+
+**After:**
+```markdown
+---
+title: Three Core Advantages
+slug: three-core-advantages
+summary: Discover the three key benefits that drive success in modern projects.
+---
+
+This is plain text.
+
+**Main advantages:**
+- Efficiency improvement
+- Cost reduction
+- Experience optimization
+
+Use `npm install` to install dependencies.
+```
+
+## Notes
+
+- Preserve original writing style and tone
+- Specify correct language for code blocks (e.g., `python`, `javascript`)
+- Maintain CJK/English spacing standards
+- Do not add content not present in original
+
+## Extension Support
+
+Custom configurations via EXTEND.md. See **Preferences** section for paths and supported options.

+## Model Resolution
+
+Model priority (highest → lowest), applies to all providers:
+
+1. CLI flag: `--model <id>`
+2. EXTEND.md: `default_model.[provider]`
+3. Env var: `<PROVIDER>_IMAGE_MODEL` (e.g., `GOOGLE_IMAGE_MODEL`)
+4. Built-in default
+
+**EXTEND.md overrides env vars**. If both EXTEND.md `default_model.google: "gemini-3-pro-image-preview"` and env var `GOOGLE_IMAGE_MODEL=gemini-3.1-flash-image-preview` exist, EXTEND.md wins.
+
+**Agent MUST display model info** before each generation:
+- Show: `Using [provider] / [model]`
+- Show switch hint: `Switch model: --model <id> | EXTEND.md default_model.[provider] | env <PROVIDER>_IMAGE_MODEL`
+
+### Replicate Models
+
+Supported model formats:
+
+- `owner/name` (recommended for official models), e.g. `google/nano-banana-pro`
+- `owner/name:version` (community models by version), e.g. `stability-ai/sdxl:<version>`
+
+Examples:
+
+```bash
+# Use Replicate default model
+npx -y bun ${SKILL_DIR}/scripts/main.ts --prompt "A cat" --image out.png --provider replicate
+
+# Override model explicitly
+npx -y bun ${SKILL_DIR}/scripts/main.ts --prompt "A cat" --image out.png --provider replicate --model google/nano-banana
+```

 ## Provider Selection

-1. `--provider` specified → use it
-2. Only one API key available → use that provider
-3. Both available → default to Google
+1. `--ref` provided + no `--provider` → auto-select Google first, then OpenAI, then Replicate
+2. `--provider` specified → use it (if `--ref`, must be `google`, `openai`, or `replicate`)
+3. Only one API key available → use that provider
+4. Multiple available → default to Google

 - OpenAI: maps to closest supported size

-## Parallel Generation
+## Generation Mode

-Supports concurrent image generation via background subagents for batch operations.
+**Default**: Sequential generation (one image at a time). This ensures stable output and easier debugging.
+
+**Parallel Generation**: Only use when user explicitly requests parallel/concurrent generation.
+
+| Mode | When to Use |
+|------|-------------|
+| Sequential (default) | Normal usage, single images, small batches |
+| Parallel | User explicitly requests, large batches (10+) |
+
+**Parallel Settings** (when requested):

 | Setting | Value |
 |---------|-------|
 | Recommended concurrency | 4 subagents |
 | Max concurrency | 8 subagents |
-| Use case | Batch generation (slides, comics, infographics) |
+| Use case | Large batch generation when user requests parallel |

-**Agent Implementation**:
+**Agent Implementation** (parallel mode only):
 ```
 # Launch multiple generations in parallel using Task tool
 # Each Task runs as background subagent with run_in_background=true
 # Collect results via TaskOutput when all complete
 ```

-**Best Practice**: When generating 4+ images, spawn background subagents (recommended 4 concurrent) instead of sequential execution.
-
 ## Error Handling

 - Missing API key → error with setup instructions
 - Generation failure → auto-retry once
 - Invalid aspect ratio → warning, proceed with default
- Reference images with non-multimodal model → warning, ignore refs
+- Reference images with unsupported provider/model → error with fix hint (switch to Google multimodal: `gemini-3-pro-image-preview`, `gemini-3.1-flash-image-preview`; or OpenAI GPT Image edits)

+options:
+  - label: "z-image-turbo (Recommended)"
+    description: "Fast generation, good quality"
+  - label: "z-image-ultra"

+
+### Update EXTEND.md
+
+After user selects a model:
+
+1. Read existing EXTEND.md
+2. If `default_model:` section exists → update the provider-specific key
+3. If `default_model:` section missing → add the full section:
+
+```yaml
+default_model:
+  google: [value or null]
+  openai: [value or null]
+  dashscope: [value or null]
+  replicate: [value or null]
+```
+
+Only set the selected provider's model; leave others as their current value or null.
+
+## After Setup
+
+1. Create directory if needed
+2. Write/update EXTEND.md with frontmatter
+3. Confirm: "Preferences saved to [path]"
+4. Continue with image generation

+# dense-modules
+
+High-density modular layout with 6-7 typed information modules packed with concrete data.
+
+## Structure
+
+- 6-7 distinct modules per image, each serving a specific information function
+- Every module contains concrete data: brand names, numbers, percentages, parameters
+- Minimal whitespace—compact spacing prioritized over breathing room
+- Smaller text acceptable to maximize information density
+- Each module identified by coordinate label or section marker (e.g., MOD-1, SEC-A)
+
+## Module Archetypes
+
+| Module | Purpose | Content Requirements |
+|--------|---------|---------------------|
+| **Brand/Selection Array** | Grid of options with recommendations | 4-8 items with icons, names, brief descriptions; highlight "best choice" |
+| **Specification Scale** | Quality/measurement gauge | 3-5 levels with precise numerical increments, quality indicators (emoji faces, checkmarks) |
+| **Deep Dive/Detail** | Technical breakdown of key item | Zoom-in callouts, internal components, cross-section or exploded view |
+| **Scenario Comparison** | Side-by-side use cases | 3-6 scenarios with specific recommendations and data per scenario |
+| **Identification Tips** | How-to checklist | 3-5 inspection methods: look/test/check/ask format |
+| **Warning/Pitfall Zone** | Critical mistakes to avoid | 3-5 pitfalls with consequences, 1-2 correct approaches; high visual contrast |
+| **Quick Reference** | Compact summary | Dense table, one-line summaries, decision flowchart, or key takeaways |
+
+## Variants
+
+| Variant | Focus | Visual Emphasis |
+|---------|-------|-----------------|
+| **Coordinate-labeled** | Precision and systematicity | Each module has alphanumeric coordinate (A-01, B-05, C-12), ruler/axis markers |
+| **Grid-cell** | Order and structure | Modules in strict rectangular cells divided by thick lines, Swiss grid feel |
+| **Free-flowing** | Organic density | Magazine-style layout with dotted frames, varying module sizes, connected by arrows |
+

+
+## Workflow
+
+### Step 0: Pre-check (Chinese Content)
+
+**Condition**: Only execute if input file contains Chinese text.
+
+**Detection**:
+1. Read input markdown file
+2. Check if content contains CJK characters (Chinese/Japanese/Korean)
+3. If no CJK content → skip to Step 1
+
+**Format Suggestion**:
+
+If CJK content detected AND `baoyu-format-markdown` skill is available:
+
+Use `AskUserQuestion` to ask whether to format first. Formatting can fix:
+- Bold markers with punctuation inside causing `**` parse failures
+- CJK/English spacing issues
+
+**If user agrees**: Invoke `baoyu-format-markdown` skill to format the file, then use formatted file as input.
+
+**If user declines**: Continue with original file.
+
+### Step 1: Determine Theme
+
+**Theme resolution order** (first match wins):
+1. User explicitly specified theme (CLI `--theme` or conversation)
+2. EXTEND.md `default_theme` (this skill's own EXTEND.md, checked in Step 0)
+3. `baoyu-post-to-wechat` EXTEND.md `default_theme` (cross-skill fallback)
+4. If none found → use AskUserQuestion to confirm
+
+**Cross-skill EXTEND.md check** (only if this skill's EXTEND.md has no `default_theme`):
+
+```bash
+# Check baoyu-post-to-wechat EXTEND.md for default_theme
+test -f "$HOME/.baoyu-skills/baoyu-post-to-wechat/EXTEND.md" && grep -o 'default_theme:.*' "$HOME/.baoyu-skills/baoyu-post-to-wechat/EXTEND.md"
+```
+
+**If theme is resolved from EXTEND.md**: Use it directly, do NOT ask the user.
+
+**If no default found**: Use AskUserQuestion to confirm:
+
+| Theme | Description |
+|-------|-------------|
+| `default` (Recommended) | 经典主题 - 传统排版，标题居中带底边，二级标题白字彩底 |
+| `grace` | 优雅主题 - 文字阴影，圆角卡片，精致引用块 |
+| `simple` | 简洁主题 - 现代极简风，不对称圆角，清爽留白 |
+| `heritage` | 传统主题 - 宋体排版，传统书法风格，默认红金配色 |
+| `warm` | 温暖主题 - 暖色调现代风，宽松行距，圆角装饰 |
+
+### Step 2: Convert
+
+```bash
+npx -y bun ${SKILL_DIR}/scripts/main.ts <markdown_file> --theme <theme>
+```
+
+### Step 3: Report Result
+
+Display the output path from JSON result. If backup was created, mention it.
+
+## Usage
+
+```bash
+npx -y bun ${SKILL_DIR}/scripts/main.ts <markdown_file> [options]
+```
+
+**Options:**
+
+| Option | Description | Default |
+|--------|-------------|---------|
+| `--theme <name>` | Theme name (default, grace, simple, heritage, warm) | default |
+| `--color <name\|hex>` | Primary color: preset name or hex value | theme default |
+| `--font-family <name>` | Font: sans, serif, serif-cjk, mono, or CSS value | theme default |
+| `--font-size <N>` | Font size: 14px, 15px, 16px, 17px, 18px | 16px |
+| `--title <title>` | Override title from frontmatter | |
+| `--keep-title` | Keep the first heading in content | false (removed) |
+| `--help` | Show help | |
+
+**Color Presets:**
+
+| Name | Hex | Label |
+|------|-----|-------|
+| blue | #0F4C81 | 经典蓝 |
+| green | #009874 | 翡翠绿 |
+| vermilion | #FA5151 | 活力橘 |

+| black | #333333 | 石墨黑 |
+| gray | #A9A9A9 | 雾烟灰 |
+| pink | #FFB7C5 | 樱花粉 |
+| red | #A93226 | 中国红 (heritage default) |
+| orange | #D97757 | 暖橘 (warm default) |
+
+**Examples:**
+
+```bash
+# Basic conversion (uses default theme, removes first heading)
+npx -y bun ${SKILL_DIR}/scripts/main.ts article.md
+
+# With specific theme
+npx -y bun ${SKILL_DIR}/scripts/main.ts article.md --theme grace
+
+# Theme with custom color
+npx -y bun ${SKILL_DIR}/scripts/main.ts article.md --theme heritage --color green
+
+# Keep the first heading in content
+npx -y bun ${SKILL_DIR}/scripts/main.ts article.md --keep-title
+
+# Override title
+npx -y bun ${SKILL_DIR}/scripts/main.ts article.md --title "My Article"
+```

-## Usage
+First-time setup: [references/config/first-time-setup.md](references/config/first-time-setup.md)

-### Image-Text (图文)
+**Minimum supported keys** (case-insensitive, accept `1/0` or `true/false`):
+
+| Key | Default | Mapping |
+|-----|---------|---------|
+| `default_author` | empty | Fallback for `author` when CLI/frontmatter not provided |
+| `need_open_comment` | `1` | `articles[].need_open_comment` in `draft/add` request |
+| `only_fans_can_comment` | `0` | `articles[].only_fans_can_comment` in `draft/add` request |
+
+**Recommended EXTEND.md example**:
+
+```md
+default_theme: default
+default_publish_method: api
+default_author: 宝玉
+need_open_comment: 1
+only_fans_can_comment: 0
+chrome_profile_path: /path/to/chrome/profile
+```
+
+**Value priority**:
+1. CLI arguments
+2. Frontmatter
+3. EXTEND.md
+4. Skill defaults
+
+## Pre-flight Check (Optional)
+
+Before first use, suggest running the environment check. User can skip if they prefer.
+
+```bash
+npx -y bun ${SKILL_DIR}/scripts/check-permissions.ts
+```
+
+Checks: Chrome, profile isolation, Bun, Accessibility, clipboard, paste keystroke, API credentials, Chrome conflicts.
+
+**If any check fails**, provide fix guidance per item:
+
+| Check | Fix |
+|-------|-----|
+| Chrome | Install Chrome or set `WECHAT_BROWSER_CHROME_PATH` env var |
+| Profile dir | Ensure `~/.local/share/wechat-browser-profile` is writable |
+| Bun runtime | `curl -fsSL https://bun.sh/install \| bash` |
+| Accessibility (macOS) | System Settings → Privacy & Security → Accessibility → enable terminal app |
+| Clipboard copy | Ensure Swift/AppKit available (macOS Xcode CLI tools: `xcode-select --install`) |
+| Paste keystroke (macOS) | Same as Accessibility fix above |
+| Paste keystroke (Linux) | Install `xdotool` (X11) or `ydotool` (Wayland) |
+| API credentials | Follow guided setup in Step 5, or manually set in `.baoyu-skills/.env` |
+
+## Image-Text Posting (图文)
+
+For short posts with multiple images (up to 9):

 ```bash
 npx -y bun ${SKILL_DIR}/scripts/wechat-browser.ts --markdown article.md --images ./images/
 npx -y bun ${SKILL_DIR}/scripts/wechat-browser.ts --title "标题" --content "内容" --image img.png --submit
 ```

-### Article (文章)
+See [references/image-text-posting.md](references/image-text-posting.md) for details.

-Before posting, ask user to choose a theme using AskUserQuestion:
+## Article Posting Workflow (文章)

-| Theme | Description |
-|-------|-------------|
-| `default` | 经典主题 - 传统排版，标题居中带底边，二级标题白字彩底 |
-| `grace` | 优雅主题 - 文字阴影，圆角卡片，精致引用块 (by @brzhang) |
-| `simple` | 简洁主题 - 现代极简风，不对称圆角，清爽留白 (by @okooo5km) |
+Copy this checklist and check off items as you complete them:

-Default: `default`. If user has already specified a theme, skip the question.
-
-**Workflow**:
-
-1. Generate HTML preview and print the full `htmlPath` from JSON output so user can click to preview:
-```bash
-npx -y bun ${SKILL_DIR}/scripts/md-to-wechat.ts article.md --theme <chosen-theme>
 ```
-2. Post to WeChat:
+Publishing Progress:
+- [ ] Step 0: Load preferences (EXTEND.md)
+- [ ] Step 1: Determine input type
+- [ ] Step 2: Check markdown-to-html skill
+- [ ] Step 3: Convert to HTML
+- [ ] Step 4: Validate metadata (title, summary, cover)
+- [ ] Step 5: Select method and configure credentials
+- [ ] Step 6: Publish to WeChat
+- [ ] Step 7: Report completion
+```
+
+### Step 0: Load Preferences
+
+Check and load EXTEND.md settings (see Preferences section above).
+
+**CRITICAL**: If not found, complete first-time setup BEFORE any other steps or questions.
+
+Resolve and store these defaults for later steps:
+- `default_author`
+- `need_open_comment` (default `1`)
+- `only_fans_can_comment` (default `0`)
+
+### Step 1: Determine Input Type
+
+| Input Type | Detection | Action |
+|------------|-----------|--------|
+| HTML file | Path ends with `.html`, file exists | Skip to Step 4 |
+| Markdown file | Path ends with `.md`, file exists | Continue to Step 2 |
+| Plain text | Not a file path, or file doesn't exist | Save to markdown, then Step 2 |
+
+**Plain Text Handling**:
+
+1. Generate slug from content (first 2-4 meaningful words, kebab-case)
+2. Create directory and save file:
+
 ```bash
-npx -y bun ${SKILL_DIR}/scripts/wechat-article.ts --markdown article.md --theme <chosen-theme>
+mkdir -p "$(pwd)/post-to-wechat/$(date +%Y-%m-%d)"
+# Save content to: post-to-wechat/yyyy-MM-dd/[slug].md
+```
+
+3. Continue processing as markdown file
+
+**Slug Examples**:
+- "Understanding AI Models" → `understanding-ai-models`
+- "人工智能的未来" → `ai-future` (translate to English for slug)
+
+### Step 2: Check Markdown-to-HTML Skill
+
+**Skip if**: Input is `.html` file
+
+**Skill Discovery**:
+
+```bash
+# Check if baoyu-markdown-to-html exists
+test -f skills/baoyu-markdown-to-html/SKILL.md && echo "found"
+```
+
+| Result | Action |
+|--------|--------|
+| Found | Read its SKILL.md, continue to Step 3 |
+| Multiple skills | AskUserQuestion to choose |
+| Not found | Show installation suggestion |
+
+**When Not Found**:
+
+```
+No markdown-to-html skill found.
+
+Suggested installation:
+https://github.com/JimLiu/baoyu-skills/blob/main/skills/baoyu-markdown-to-html/SKILL.md
+
+Options:
+A) Cancel - install the skill first
+B) Continue - provide HTML file manually
+```
+
+### Step 3: Convert Markdown to HTML
+
+**Skip if**: Input is `.html` file
+
+1. **Resolve theme** (first match wins, do NOT ask user if resolved):
+   - CLI `--theme` argument
+   - EXTEND.md `default_theme` (loaded in Step 0)
+   - Fallback: `default`
+
+2. **Execute conversion** (using the discovered skill), **always pass `--theme`**:
+
+```bash
+npx -y bun ${MD_TO_HTML_SKILL_DIR}/scripts/main.ts <markdown_file> --theme <theme>
+```
+
+**CRITICAL**: Always include `--theme` parameter. Never omit it, even if using `default`.
+
+3. **Parse JSON output** to get: `htmlPath`, `title`, `author`, `summary`, `contentImages`
+
+### Step 4: Validate Metadata
+
+Check extracted metadata from Step 3 (or HTML meta tags if direct HTML input).
+
+| Field | If Missing |
+|-------|------------|
+| Title | Prompt: "Enter title, or press Enter to auto-generate from content" |
+| Summary | Prompt: "Enter summary, or press Enter to auto-generate (recommended for SEO)" |
+| Author | Use fallback chain: CLI `--author` → frontmatter `author` → EXTEND.md `default_author` |
+
+**Auto-Generation Logic**:
+- **Title**: First H1/H2 heading, or first sentence
+- **Summary**: First paragraph, truncated to 120 characters
+
+**Cover Image Check** (required for `article_type=news`):
+1. Use CLI `--cover` if provided.
+2. Else use frontmatter (`coverImage`, `featureImage`, `cover`, `image`).
+3. Else check article directory default path: `imgs/cover.png`.
+4. Else fallback to first inline content image.
+5. If still missing, stop and request a cover image before publishing.
+
+### Step 5: Select Publishing Method and Configure
+
+**Ask publishing method** (unless specified in EXTEND.md or CLI):
+
+| Method | Speed | Requirements |
+|--------|-------|--------------|
+| `api` (Recommended) | Fast | API credentials |
+| `browser` | Slow | Chrome, login session |
+
+**If API Selected - Check Credentials**:
+
+```bash
+# Check project-level
+test -f .baoyu-skills/.env && grep -q "WECHAT_APP_ID" .baoyu-skills/.env && echo "project"
+
+# Check user-level
+test -f "$HOME/.baoyu-skills/.env" && grep -q "WECHAT_APP_ID" "$HOME/.baoyu-skills/.env" && echo "user"
+```
+
+**If Credentials Missing - Guide Setup**:
+
+```
+WeChat API credentials not found.
+
+To obtain credentials:
+1. Visit https://mp.weixin.qq.com
+2. Go to: 开发 → 基本配置
+3. Copy AppID and AppSecret
+
+Where to save?
+A) Project-level: .baoyu-skills/.env (this project only)
+B) User-level: ~/.baoyu-skills/.env (all projects)
+```
+
+After location choice, prompt for values and write to `.env`:
+
+```
+WECHAT_APP_ID=<user_input>
+WECHAT_APP_SECRET=<user_input>
+```
+
+### Step 6: Publish to WeChat
+
+**API method**:
+
+```bash
+npx -y bun ${SKILL_DIR}/scripts/wechat-api.ts <html_file> [--title <title>] [--summary <summary>] [--author <author>] [--cover <cover_path>]
+```
+
+**`draft/add` payload rules**:
+- Use endpoint: `POST https://api.weixin.qq.com/cgi-bin/draft/add?access_token=ACCESS_TOKEN`
+- `article_type`: `news` (default) or `newspic`
+- For `news`, include `thumb_media_id` (cover is required)
+- Always resolve and send:
+  - `need_open_comment` (default `1`)
+  - `only_fans_can_comment` (default `0`)
+- `author` resolution: CLI `--author` → frontmatter `author` → EXTEND.md `default_author`
+
+If script parameters do not expose the two comment fields, still ensure final API request body includes resolved values.
+
+**Browser method**:
+
+```bash
+npx -y bun ${SKILL_DIR}/scripts/wechat-article.ts --html <html_file>
+```
+
+### Step 7: Completion Report
+
+**For API method**, include draft management link:
+
+```
+WeChat Publishing Complete!
+
+Input: [type] - [path]
+Method: API
+Theme: [theme name]
+
+Article:
+• Title: [title]
+• Summary: [summary]
+• Images: [N] inline images
+• Comments: [open/closed], [fans-only/all users]
+
+Result:
+✓ Draft saved to WeChat Official Account
+• media_id: [media_id]
+
+Next Steps:
+→ Manage drafts: https://mp.weixin.qq.com (登录后进入「内容管理」→「草稿箱」)
+
+Files created:
+[• post-to-wechat/yyyy-MM-dd/slug.md (if plain text)]
+[• slug.html (converted)]
+```
+
+**For Browser method**:
+
+```

+
+Input: [type] - [path]
+Method: Browser

+## Troubleshooting
+
+### Chrome debug port not ready
+
+If a script fails with `Chrome debug port not ready` or `Unable to connect`, kill existing Chrome CDP instances first, then retry:
+
+```bash
+pkill -f "Chrome.*remote-debugging-port" 2>/dev/null; pkill -f "Chromium.*remote-debugging-port" 2>/dev/null; sleep 2
+```
+
+**Important**: This should be done automatically — when encountering this error, kill Chrome CDP instances and retry the command without asking the user.
+
 ## Notes

 - First run: manual login required (session persists)
- Always preview before `--submit`
+- All scripts only fill content into the browser, user must review and publish manually
 - Cross-platform: macOS, Linux, Windows
