Agent Skills: Post to Weibo

Post to Weibo

Posts text, images, videos, and long-form articles to Weibo via real Chrome browser (bypasses anti-bot detection).

Script Directory

Important: All scripts are located in the scripts/ subdirectory of this skill.

Agent Execution Instructions:

1. Determine this SKILL.md file's directory path as {baseDir}
2. Script path = {baseDir}/scripts/<script-name>.ts
3. Replace all {baseDir} in this document with the actual path
4. Resolve ${BUN_X} runtime: if bun installed → bun; if npx available → npx -y bun; else suggest installing bun

Script Reference: | Script | Purpose | |--------|---------| | scripts/weibo-post.ts | Regular posts (text + images) | | scripts/weibo-article.ts | Headline article publishing (Markdown) | | scripts/copy-to-clipboard.ts | Copy content to clipboard | | scripts/paste-from-clipboard.ts | Send real paste keystroke |

# 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" }

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 (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.

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
