+
+Based on `download_media` setting in EXTEND.md:

+
+### 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?"

+# 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)     |

+| 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
+

+## 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

+When generating multiple images in a series:
+
+1. **Image 1 (cover)**: Generate without `--ref` — this establishes the visual anchor
+2. **Images 2+**: Always pass image 1 as `--ref` to the image generation skill:
+   ```bash
+   npx -y bun ${SKILL_DIR}/scripts/main.ts \
+     --promptfiles prompts/02-content-xxx.md \
+     --ref path/to/01-cover-xxx.png \
+     --image 02-content-xxx.png --ar 3:4 --quality 2k
+   ```
+   This ensures the AI maintains the same character design, illustration style, and color rendering across the series.
+
+### Step 6: Combine

 Assemble all sections into final prompt following base structure.

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.

jeffrey94	49403b6fab	feat(baoyu-xhs-images): add reference image chain for visual consistency When generating multi-image series, use image 1 as --ref for all subsequent images. This anchors character design, color rendering, and illustration style across the entire series — critical for styles with recurring characters or mascots.
