 ## Running Skills
 
-All scripts run via Bun (no build step):
+All scripts are TypeScript, executed via Bun runtime (no build step).
+
+### Runtime Detection (`${BUN_X}`)
+
+Before running any script, the agent MUST detect the runtime **once per session** and set `${BUN_X}`:
 
 ```bash
-npx -y bun skills/<skill>/scripts/main.ts [options]
+# Detect runtime (run once, reuse result)
+if command -v bun &>/dev/null; then
+  BUN_X="bun"
+elif command -v npx &>/dev/null; then
+  BUN_X="npx -y bun"
+else
+  echo "Error: Neither bun nor npx found. Install bun: brew install oven-sh/bun/bun (macOS) or npm install -g bun"
+  exit 1
+fi
+```
+
+| Priority | Condition | `${BUN_X}` value | Notes |
+|----------|-----------|-------------------|-------|
+| 1 | `bun` installed | `bun` | Fastest, native execution |
+| 2 | `npx` available | `npx -y bun` | Downloads bun on first run via npm |
+| 3 | Neither found | Error + install guide | `brew install oven-sh/bun/bun` (macOS) or `npm install -g bun` |
+
+### Script Execution
+
+```bash
+${BUN_X} skills/<skill>/scripts/main.ts [options]
 ```
 
 Examples:
 ```bash
 # Text generation
-npx -y bun skills/baoyu-danger-gemini-web/scripts/main.ts "Hello"
+${BUN_X} skills/baoyu-danger-gemini-web/scripts/main.ts "Hello"
 
 # Image generation
-npx -y bun skills/baoyu-danger-gemini-web/scripts/main.ts --prompt "A cat" --image cat.png
+${BUN_X} skills/baoyu-danger-gemini-web/scripts/main.ts --prompt "A cat" --image cat.png
 
 # From prompt files

+${BUN_X} skills/baoyu-danger-gemini-web/scripts/main.ts --promptfiles system.md content.md --image out.png
 ```
 
 ## Key Dependencies
 
-- **Bun**: TypeScript runtime (via `npx -y bun`)
+- **Bun**: TypeScript runtime (native `bun` preferred, fallback `npx -y bun`)
 - **Chrome**: Required for `baoyu-danger-gemini-web` auth and `baoyu-post-to-x` automation
 - **No npm packages**: Self-contained TypeScript, no external dependencies
 
+## Chrome Profile (Unified)
+
+All skills that use Chrome CDP share a **single** profile directory. Do NOT create per-skill profiles.
+
+| Platform | Default Path |
+|----------|-------------|
+| macOS | `~/Library/Application Support/baoyu-skills/chrome-profile` |
+| Linux | `$XDG_DATA_HOME/baoyu-skills/chrome-profile` (fallback `~/.local/share/baoyu-skills/chrome-profile`) |
+| Windows | `%APPDATA%/baoyu-skills/chrome-profile` |
+| WSL | Windows home `/.local/share/baoyu-skills/chrome-profile` |
+
+**Environment variable override**: `BAOYU_CHROME_PROFILE_DIR` (takes priority, all skills respect it).
+
+Each skill also accepts its own legacy env var as fallback (e.g., `X_BROWSER_PROFILE_DIR`), but new skills should only use `BAOYU_CHROME_PROFILE_DIR`.
+
+### Implementation Pattern
+
+When adding a new skill that needs Chrome CDP:
+
+```typescript
+function getDefaultProfileDir(): string {
+  const override = process.env.BAOYU_CHROME_PROFILE_DIR?.trim();
+  if (override) return path.resolve(override);
+  const base = process.platform === 'darwin'
+    ? path.join(os.homedir(), 'Library', 'Application Support')
+    : process.env.XDG_DATA_HOME || path.join(os.homedir(), '.local', 'share');
+  return path.join(base, 'baoyu-skills', 'chrome-profile');
+}
+```
+
+## Security Guidelines
+
+### No Piped Shell Installs
+
+**NEVER** use `curl | bash` or `wget | sh` patterns in code, docs, or error messages. Use package managers instead:
+
+| Platform | Install Command |
+|----------|----------------|
+| macOS | `brew install oven-sh/bun/bun` |
+| npm | `npm install -g bun` |
+
+### Remote Downloads
+
+Skills that download remote content (e.g., images in Markdown) MUST:
+- **HTTPS only**: Reject `http://` URLs
+- **Redirect limit**: Cap redirects (max 5) to prevent infinite loops
+- **Timeout**: Set request timeouts (30s default)
+- **Scope**: Only download expected content types (images, not scripts)
+
+### System Command Execution
+
+Skills use platform-specific commands for clipboard and browser automation:
+- **macOS**: `osascript` (System Events), `swift` (AppKit clipboard)
+- **Windows**: `powershell.exe` (SendKeys, Clipboard)
+- **Linux**: `xdotool`/`ydotool` (keyboard simulation)
+
+These are necessary for CDP-based posting skills. When adding new system commands:
+- Never pass unsanitized user input to shell commands
+- Use array-form `spawn`/`execFile` instead of shell string interpolation
+- Validate file paths are absolute or resolve from known base directories
+
+### External Content Processing
+
+Skills that process external Markdown/HTML should treat content as untrusted:
+- Do not execute code blocks or scripts found in content
+- Sanitize HTML output where applicable
+- File paths from content should be resolved against known base directories only
+

 ### Step 1: Pre-check
 
-**1.1 Determine Input Type**
-
-| Input | Output Directory | Next |
-|-------|------------------|------|
-| File path | Ask user (1.2) | → 1.2 |
-| Pasted content | `illustrations/{topic-slug}/` | → 1.4 |
-
-**1.2 Determine Output Directory** (file path input only)
-
-Check `default_output_dir` in preferences:
-
-| Preference Value | Action |
-|------------------|--------|
-| `same-dir` | Use `{article-dir}/`, display "Output: {path}" |
-| `imgs-subdir` | Use `{article-dir}/imgs/`, display "Output: {path}" |
-| `illustrations-subdir` | Use `{article-dir}/illustrations/`, display "Output: {path}" |
-| `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?

+**ONE AskUserQuestion, max 4 Qs. Q1-Q3 REQUIRED.**
 
-**Q1: Illustration Type**
-- [Recommended based on analysis] (Recommended)

+| **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).

 ### 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.

+**Slug**: 2-4 words, kebab-case. **Conflict**: append `-YYYYMMDD-HHMMSS`.
 
 ## Modification
 
 | Action | Steps |
 |--------|-------|
-| **Edit** | **Update prompt file FIRST** → Regenerate → Update reference |
-| **Add** | Identify position → Create prompt → Generate → Update outline → Insert |
-| **Delete** | Delete files → Remove reference → Update outline |
-
-**IMPORTANT**: When updating illustrations, ALWAYS update the prompt file (`prompts/illustration-{slug}.md`) FIRST before regenerating. This ensures:
-1. Changes are documented and reproducible
-2. The prompt reflects the new requirements
-3. Future regeneration uses the correct prompt
+| Edit | Update prompt → Regenerate → Update reference |
+| Add | Position → Prompt → Generate → Update outline → Insert |

 # 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
+    filename: 01-ref-diagram.png
+    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 |
+
+**If no reference file but style/palette extracted verbally**, append directly to prompt body:
+```
+COLORS (from reference):
+- Primary: #E8756D coral
+- 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
+# macOS, Linux, WSL, Git Bash
+test -f .baoyu-skills/baoyu-article-illustrator/EXTEND.md && echo "project"
+test -f "$HOME/.baoyu-skills/baoyu-article-illustrator/EXTEND.md" && echo "user"
+```
+
+```powershell
+# PowerShell (Windows)
+if (Test-Path .baoyu-skills/baoyu-article-illustrator/EXTEND.md) { "project" }
+if (Test-Path "$HOME/.baoyu-skills/baoyu-article-illustrator/EXTEND.md") { "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)
+- [Top compatible core style 1]
+- [Top compatible core style 2]
+- Other (see full Style Gallery)
+
+If no `preferred_style` (present Core Styles first):
+- [Best compatible core style] (Recommended)
+- [Other compatible core style 1]
+- [Other compatible core style 2]
+- Other (see full Style Gallery)
+
+**Core Styles** (simplified selection):
+
+| Core Style | Best For |
+|------------|----------|
+| `minimal-flat` | General, knowledge sharing, SaaS |
+| `sci-fi` | AI, frontier tech, system design |
+| `hand-drawn` | Relaxed, reflective, casual |
+| `editorial` | Processes, data, journalism |
+| `scene` | Narratives, emotional, lifestyle |
+
+Style selection based on Type × Style compatibility matrix (styles.md).
+Full specs: `styles/<style>.md`
+
+### 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.
+
+### 6.2 Output Summary
+
+```
+Article Illustration Complete!

 ### 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`)
+3. **Analyze content**: topic, tone, keywords, visual metaphors
+4. **Deep analyze references** ⚠️: Extract specific, concrete elements (see reference-images.md)

-- 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

+- **Visual anchor placement**: Main element centered or offset left (reserve right side for title if included)
+- **Information hierarchy**: One dominant focal point, 1-2 supporting elements, decorative accents
+- **Clean backgrounds**: Solid colors or subtle gradients; no complex textures or patterns

+|----------|----------|
+| Tech | Code window, gear, circuit, cloud, lock, API brackets |
+| Ideas | Lightbulb, rocket, target, puzzle, key, magnifier |
+| Communication | Speech bubble, chat dots, megaphone, mail |
+| Growth | Plant/sprout, tree, arrow, chart, mountain |

+## 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

+
+**CRITICAL**: When EXTEND.md is not found, you **MUST use `AskUserQuestion`** to ask the user for their preferences before creating EXTEND.md. **NEVER** create EXTEND.md with defaults without asking. This is a **BLOCKING** operation — do NOT proceed with any conversion until setup is complete.
+
+Use `AskUserQuestion` with ALL questions in ONE call:
+
+**Question 1** — header: "Media", question: "How to handle images and videos in tweets?"
+- "Ask each time (Recommended)" — After saving markdown, ask whether to download media
+- "Always download" — Always download media to local imgs/ and videos/ directories
+- "Never download" — Keep original remote URLs in markdown
+
+**Question 2** — header: "Output", question: "Default output directory?"
+- "x-to-markdown (Recommended)" — Save to ./x-to-markdown/{username}/{tweet-id}.md
+- (User may choose "Other" to type a custom path)
+
+**Question 3** — header: "Save", question: "Where to save preferences?"
+- "User (Recommended)" — ~/.baoyu-skills/ (all projects)
+- "Project" — .baoyu-skills/ (this project only)
+
+After user answers, create EXTEND.md at the chosen location, confirm "Preferences saved to [path]", then continue.

+## Media Download Workflow
+
+Based on `download_media` setting in EXTEND.md:
+
+| Setting | Behavior |
+|---------|----------|
+| `1` (always) | Run script with `--download-media` flag |
+| `0` (never) | Run script without `--download-media` flag |
+| `ask` (default) | Follow the ask-each-time flow below |
+
+### Ask-Each-Time Flow
+
+1. Run script **without** `--download-media` → markdown saved
+2. Check saved markdown for remote media URLs (`https://` in image/video links)
+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.

 # Markdown Formatter
 
-Transforms plain text or markdown files into well-structured markdown with proper frontmatter, formatting, and typography.
+Transforms plain text or markdown into well-structured, reader-friendly markdown. The goal is to help readers quickly grasp key points, highlights, and structure — without changing any original content.
+
+**Core principle**: Only adjust formatting and fix obvious typos. Never add, delete, or rewrite content.
 
 ## Script Directory
 
-Scripts in `scripts/` subdirectory. Replace `${SKILL_DIR}` with this SKILL.md's directory path.
+Scripts in `scripts/` subdirectory. `${SKILL_DIR}` = this SKILL.md's directory path. Resolve `${BUN_X}` runtime: if `bun` installed → `bun`; if `npx` available → `npx -y bun`; else suggest installing bun. Replace `${SKILL_DIR}` and `${BUN_X}` with actual values.

 |--------|---------|
-| `scripts/main.ts` | Main entry point with CLI options |
-| `scripts/cjk-emphasis.ts` | Fix CJK emphasis/bold punctuation issues |

-### Step 2: Analyze Content Structure
+### Step 2: Analyze Content (Reader's Perspective)
 
-Identify:
-- Existing title (H1 `#`)
-- Paragraph separations
-- Keywords suitable for **bold**
-- Parallel content convertible to lists
-- Code snippets
-- Quotations
+Read the entire content carefully. Think from a reader's perspective: what would help them quickly understand and remember the key information?
 
-### Step 3: Check/Create Frontmatter
+Produce an analysis covering these dimensions:
+
+**2.1 Highlights & Key Insights**
+- Core arguments or conclusions the author makes
+- Surprising facts, data points, or counterintuitive claims
+- Memorable quotes or well-phrased sentences (golden quotes)
+
+**2.2 Structure Assessment**
+- Does the content have a clear logical flow? What is it?
+- Are there natural section boundaries that lack headings?
+- Are there long walls of text that could benefit from visual breaks?
+
+**2.3 Reader-Important Information**
+- Actionable advice or takeaways
+- Definitions, explanations of key concepts
+- Lists or enumerations buried in prose
+- Comparisons or contrasts that would be clearer as tables
+
+**2.4 Formatting Issues**
+- Missing or inconsistent heading hierarchy
+- Paragraphs that mix multiple topics
+- Parallel items written as prose instead of lists
+- Code, commands, or technical terms not marked as code
+- Obvious typos or formatting errors
+
+**Save analysis to file**: `{original-filename}-analysis.md`
+
+The analysis file serves as the blueprint for Step 3. Use this format:
+
+```markdown
+# Content Analysis: {filename}
+
+## Highlights & Key Insights
+- [list findings]
+
+## Structure Assessment
+- Current flow: [describe]
+- Suggested sections: [list heading candidates with brief rationale]
+
+## Reader-Important Information
+- [list actionable items, key concepts, buried lists, potential tables]
+
+## Formatting Issues
+- [list specific issues with location references]
+
+## Typos Found
+- [list any obvious typos with corrections, or "None found"]
+```
+
+### Step 3: Check/Create Frontmatter, Title & Summary
 
 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) |
-| `featureImage` | Check if `imgs/cover.png` exists in same directory; if so, use relative path |
+| `title` | See **Title Generation** below |
+| `slug` | Infer from file path or generate from title |
+| `summary` | See **Summary Generation** below |
+| `coverImage` | Check if `imgs/cover.png` exists in same directory; if so, use relative path |
 
-### Step 4: Title Handling
+**Title Generation:**
 
-**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:
+Generate 3 candidate titles with different angles/styles. Present to user for selection:
 
 ```
-Select a title:
+Pick a title:
 
-1. [Title A] (Recommended)
-2. [Title B]
-3. [Title C]
+1. [Title A] — [angle/style note]
+2. [Title B] — [angle/style note]
+3. [Title C] — [angle/style note]
+
+Enter number, or type a custom title:
 ```
 
-3. If no selection within a few seconds, use recommended (option 1)
-
-**Title principles:**
-- Concise, max 20 characters
-- Captures core message
+Title principles:
 - Engaging, sparks reading interest
+- Captures core message or most compelling angle
 - Accurate, avoids clickbait
+- Vary angles: e.g. story-driven, conclusion-driven, question-driven
 
-**Important:** Once title is in frontmatter, body should NOT have H1 (avoid duplication)
+If frontmatter already has `title`, skip selection and use it. If first line is H1, extract to frontmatter as default title but still offer alternatives.
 
-### Step 5: Format Processing
+**Summary Generation:**
 
-**Formatting rules:**
+Generate 3 candidate summaries with different focuses. Present to user for selection:
 
-| 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 |
+```
+Pick a summary:
 
-**Formatting principles:**
-- Preserve original content and viewpoints
-- Add formatting only, do not modify text
-- Formatting serves readability
-- Avoid over-formatting
+1. [Summary A] — [focus note]
+2. [Summary B] — [focus note]
+3. [Summary C] — [focus note]
 
-### Step 6: Save Formatted File
+Enter number, or type a custom summary:
+```
+
+Summary principles:
+- 80-150 characters, precise and information-rich
+- Convey article's core value, not just topic
+- Vary focuses: e.g. problem-driven, result-driven, insight-driven
+- Avoid generic descriptions like "本文介绍了..."
+
+If frontmatter already has `summary`, skip selection and use it.
+
+**EXTEND.md skip behavior:** If `auto_select: true` is set in EXTEND.md, skip title and summary selection — generate the best candidate directly without asking. User can also set `auto_select_title: true` or `auto_select_summary: true` independently.
+
+Once title is in frontmatter, body should NOT have H1 (avoid duplication).
+
+### Step 4: Format Content
+
+Apply formatting guided by the Step 2 analysis. The goal is making the content scannable and the key points impossible to miss.
+
+**Formatting toolkit:**
+
+| Element | When to use | Format |
+|---------|-------------|--------|
+| Headings | Natural topic boundaries, section breaks | `##`, `###` hierarchy |
+| Bold | Key conclusions, important terms, core takeaways | `**bold**` |
+| Unordered lists | Parallel items, feature lists, examples | `- item` |
+| Ordered lists | Sequential steps, ranked items, procedures | `1. item` |
+| Tables | Comparisons, structured data, option matrices | Markdown table |
+| Code | Commands, file paths, technical terms, variable names | `` `inline` `` or fenced blocks |
+| Blockquotes | Notable quotes, important warnings, cited text | `> quote` |
+| Separators | Major topic transitions | `---` |
+
+**Formatting principles — what NOT to do:**
+- Do NOT add sentences, explanations, or commentary
+- Do NOT delete or shorten any content
+- Do NOT rephrase or rewrite the author's words
+- Do NOT add headings that editorialize (e.g., "Amazing Discovery" — use neutral descriptive headings)
+- Do NOT over-format: not every sentence needs bold, not every paragraph needs a heading
+
+**Formatting principles — what TO do:**
+- Preserve the author's voice, tone, and every word
+- Use bold sparingly for genuinely important points
+- Extract parallel items from prose into lists only when the structure is clearly there
+- Add headings where the topic genuinely shifts
+- Fix obvious typos (based on Step 2 findings)
+
+### Step 5: 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"

-```
-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

-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.
-```
+Adjust the report to reflect actual changes — omit categories where no changes were made.
 
 ## 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
+- The analysis file is a working document — it helps maintain consistency between what was identified and what was formatted

+## 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
+${BUN_X} ${SKILL_DIR}/scripts/main.ts --prompt "A cat" --image out.png --provider replicate
+
+# Override model explicitly
+${BUN_X} ${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. Multiple available → default to Google
+1. `--ref` provided + no `--provider` → auto-select Google first, then OpenAI, then Replicate

+    description: "Google's base image model on Replicate"
+```
+
+### 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 |
+
+## Best For
+
+- Product selection guides and buying guides
+- Multi-dimensional comparison content
+- Data-rich educational materials
+- "Avoid pitfalls" / "complete guide" formats
+- Content targeting platforms like Xiaohongshu with high-density visual requirements
+
+## Visual Elements
+
+- Module boundary markers (thick lines, dotted frames, or coordinate grids)
+- Quality indicators per module (emoji faces, checkmarks, crosses, crowns)
+- Data callout boxes with highlighted numbers
+- Comparison arrows and progression indicators
+- Warning/alert visual markers for pitfall modules
+- Metadata in corners (page numbers, timestamps, small barcodes)
+
+## Text Placement
+
+- Main title at top, prominent and impactful
+- Subtitle with module count ("X大维度全面解析...")
+- Module headers inside colored badges or labeled frames
+- Body text compact, multiple columns within modules
+- Numbers highlighted with accent colors, slightly larger than body text
+
+## Information Density Rules
+
+- Every corner should contain useful information or metadata
+- No decorative-only empty space
+- Text size may be reduced to fit more content—information over font size
+- Each module must have specific data points, not generic descriptions
+- Balance between density and readability: dense but organized
+
+## Recommended Pairings
+
+- `pop-laboratory`: Technical precision with coordinate markers and blueprint grid
+- `morandi-journal`: Hand-drawn warmth with doodle illustrations and organic frames
+- `retro-pop-grid`: 1970s pop art with strict grid cells and bold contrast
+- `corporate-memphis`: Clean business feel for product comparisons
+- `technical-schematic`: Engineering precision for technical product guides

+- Dotted line frames around sections
+- Connecting arrows and dotted lines between modules
+- Corner decorations: tiny houses, stars, sparkles, clouds
+- Wavy line dividers between sections
+- Callout bubbles for tips
+- Magnifying glass icons for identification tips
+- Thumbs up/down icons (hand-drawn style)
+
+## Variants
+
+| Variant | Focus | Visual Emphasis |

+- Module headers: Clean handwritten text in white on dark teal rounded badge (#6B9080)
+- Body text: Neat handwritten print style, easy to read
+- Numbers: Highlighted in terracotta (#D4956A), slightly larger than body
+
+## Style Enforcement
+
+- All imagery must maintain hand-drawn/doodle aesthetic—no digital precision
+- Organic, slightly imperfect shapes throughout
+- Sketch-like quality with visible line weight variations
+- Warm and cozy journal feel, not clinical or corporate
+
+## Avoid

+- Strict Swiss international grid: poster divided into square and rectangular cells by thick black lines
+- Black-background cells with white text for warnings or key categories (inverted contrast)
+- Geometric fill patterns in empty cells: checkerboards, diagonal lines, dots
+- Flat abstract symbols, warning signs, keyholes, stars, arrows
+- Vintage comic-style smiley/frowny faces for quality indicators
+- Colored cells used for breathing room—some with minimal/no content
+
+## Typography
+
+- Headers: Bold brutalist or retro thick display fonts, high legibility
+- Body: Clean sans-serif, structured typographic alignment
+- Decorative English text acceptable for stylistic labels ("WARNING", "INFO", "BEST")
