Parameter	Description
<text>	Post content (positional)

--video <path>	Video file (repeatable)
--profile <dir>	Custom Chrome profile

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:

Parameter	Description
<markdown>	Markdown file (positional)
--cover <path>	Cover image
--title <text>	Override title (max 32 chars, truncated if longer)
--summary <text>	Override summary (max 44 chars, auto-regenerated if longer)
--profile <dir>	Custom Chrome profile

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)

Markdown-to-HTML: Do NOT pass any --theme parameter when converting markdown to HTML. Use the default theme (no theme argument).

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.

---

Post Type Selection

Unless the user explicitly specifies the post type:

• Markdown file (.md) → Headline Article (头条文章)
• Plain text / text with images → Regular Post

Troubleshooting

Chrome debug port not ready

If a script fails with Chrome debug port not ready or Unable to connect, kill only the CDP Chrome instances (those with --remote-debugging-port AND the baoyu-skills profile), then retry:

pkill -f "remote-debugging-port.*baoyu-skills/chrome-profile" 2>/dev/null; sleep 2

CRITICAL: Never kill all Chrome processes (pkill -f "Google Chrome"). Only kill Chrome instances launched by CDP with the baoyu-skills profile directory. The user may have regular Chrome windows open.

Important: This should be done automatically -- when encountering this error, kill the CDP Chrome 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
