+   ```
+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

+
+**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.

+## Replicate Model Configuration
+
+When using `--provider replicate`, the model can be configured in the following ways (highest priority first):
+
+1. CLI flag: `--model <owner/name>`
+2. EXTEND.md: `default_model.replicate`
+3. Env var: `REPLICATE_IMAGE_MODEL`
+4. Built-in default: `google/nano-banana-pro`
+
+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
+```
+

+# 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

+
+- Main title: Bold hand-lettered calligraphy style with decorative flourishes
+- 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

+- Cross-hair targets, mathematical symbols (Σ, Δ, ∞), directional arrows (X/Y axis)
+- Microscopic detail annotations alongside macroscopic bold headers
+- Corner metadata: tiny barcodes, timestamps, technical parameters
+- High contrast between massive bold headers and tiny 8pt-style annotations

+## 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

LyInfi	1bdf44df9e	fix(wechat-browser): fix upload progress check crashing on second iteration Runtime.evaluate reuses the same JS execution context across calls in a session. The previous expression used `const thumbs = ...` which throws "Identifier 'thumbs' has already been declared" on the second loop iteration, causing result.value to be undefined and JSON.parse to throw "JSON Parse error: Unexpected identifier 'undefined'". Fix by inlining the querySelector into a single expression with no variable declaration, eliminating the re-declaration error.
