Preferences (EXTEND.md)

Check EXTEND.md existence (priority order):

# macOS, Linux, WSL, Git Bash
test -f .baoyu-skills/baoyu-post-to-weibo/EXTEND.md && echo "project"
test -f "${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-post-to-weibo/EXTEND.md" && echo "xdg"
test -f "$HOME/.baoyu-skills/baoyu-post-to-weibo/EXTEND.md" && echo "user"

# PowerShell (Windows)
if (Test-Path .baoyu-skills/baoyu-post-to-weibo/EXTEND.md) { "project" }
$xdg = if ($env:XDG_CONFIG_HOME) { $env:XDG_CONFIG_HOME } else { "$HOME/.config" }
if (Test-Path "$xdg/baoyu-skills/baoyu-post-to-weibo/EXTEND.md") { "xdg" }
if (Test-Path "$HOME/.baoyu-skills/baoyu-post-to-weibo/EXTEND.md") { "user" }

EXTEND.md Supports: Default Chrome profile

Prerequisites

• Google Chrome or Chromium
• bun runtime
• First run: log in to Weibo manually (session saved)

Regular Posts

Text + images/videos (max 18 files total). Posted on Weibo homepage.

${BUN_X} {baseDir}/scripts/weibo-post.ts "Hello Weibo!" --image ./photo.png
${BUN_X} {baseDir}/scripts/weibo-post.ts "Watch this" --video ./clip.mp4

Parameters:

Note: Script opens browser with content filled in. User reviews and publishes manually.

Headline Articles (头条文章)

Long-form Markdown articles published at https://card.weibo.com/article/v3/editor.

${BUN_X} {baseDir}/scripts/weibo-article.ts article.md
${BUN_X} {baseDir}/scripts/weibo-article.ts article.md --cover ./cover.jpg

Parameters:

Frontmatter: title, summary, cover_image supported in YAML front matter.

Character Limits:

• Title: 32 characters max (truncated with warning if longer)
• Summary/导语: 44 characters max (auto-regenerated from content if longer)

Article Workflow:

1. Opens https://card.weibo.com/article/v3/editor
2. Clicks "写文章" button, waits for editor to become editable
3. Fills title (validated for 32-char limit)
4. Fills summary/导语 (validated for 44-char limit)
5. Inserts HTML content into ProseMirror editor via paste
6. Replaces image placeholders one by one (copy image → select placeholder → paste)

Post-Composition Check: The script automatically verifies after all images are inserted:

• Remaining WBIMGPH_ placeholders in editor content
• Expected vs actual image count

If the check fails (warnings in output), alert the user with the specific issues before they publish.

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:

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)
• All scripts only fill content into the browser, user must review and publish manually
• Cross-platform: macOS, Linux, Windows

Extension Support
