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: | Parameter | Description | |-----------|-------------| | <text> | Post content (positional) | | --image <path> | Image file (repeatable) | | --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 (頭條文章)

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/導語: 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:

Opens https://card.weibo.com/article/v3/editor
Clicks "寫文章" button, waits for editor to become editable
Fills title (validated for 32-char limit)
Fills summary/導語 (validated for 44-char limit)
Inserts HTML content into ProseMirror editor via paste
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 (頭條文章)
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

Extension Support

Custom configurations via EXTEND.md. See Preferences section for paths and supported options.
