The file
We split this skill into the rules it gives an agent
9 rules. 0 are common, 8 are distinctive, and 1 is very specific to this project.
0
Common
Most of the 4 edited versions we read keep these.
8
Distinctive
This author's own choices. Worth a look.
1
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Very specific: line 116
Use parse_markdown.py to extract all structured data:
- Distinctive: line 173
If login needed, prompt user to log in manually.
- Distinctive: line 178
Use browser_file_upload with the cover image path (from JSON output)
- Distinctive: line 184
Use browser_type to input title (from JSON output)
- Distinctive: line 268
Verify content pasted (check word count indicator)
- Distinctive: line 275
NEVER publish: - Only save draft
- Distinctive: line 277
Rich text conversion: - Always convert Markdown to HTML before pasting
- Distinctive: line 279
Block index positioning: - Use block_index for precise image placement
- Distinctive: line 318
Wait until upload complete
“Common” is measured: kept by at least 6 in 10 of the 4 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
X Article Publisher
Publish Markdown content to X (Twitter) Articles editor, preserving formatting with rich text conversion.
Prerequisites
- Playwright MCP for browser automation
- User logged into X with Premium Plus subscription
- Python 3.9+ with dependencies:
- macOS:
pip install Pillow pyobjc-framework-Cocoa - Windows:
pip install Pillow pywin32 clip-util
- macOS:
Scripts
Located in ~/.claude/skills/x-article-publisher/scripts/:
parse_markdown.py
Parse Markdown and extract structured data:
python parse_markdown.py <markdown_file> [--output json|html] [--html-only]Returns JSON with: title, cover_image, content_images (with block_index for positioning), html, total_blocks
copy_to_clipboard.py
Copy image or HTML to system clipboard:
# Copy image (with optional compression)
python copy_to_clipboard.py image /path/to/image.jpg [--quality 80]
# Copy HTML for rich text paste
python copy_to_clipboard.py html --file /path/to/content.htmlWorkflow
Strategy: "先文后图" (Text First, Images Later)
For articles with multiple images, paste ALL text content first, then insert images at correct positions using block index.
- Parse Markdown with Python script → get title, images with block_index, HTML
- Navigate to X Articles editor
- Upload cover image (first image)
- Fill title
- Copy HTML to clipboard (Python) → Paste with Cmd+V
- Insert content images at positions specified by block_index
- Save as draft (NEVER auto-publish)
高效执行原则 (Efficiency Guidelines)
目标: 最小化操作之间的等待时间,实现流畅的自动化体验。
1. 避免不必要的 browser_snapshot
大多数浏览器操作(click, type, press_key 等)都会在返回结果中包含页面状态。不要在每次操作后单独调用 browser_snapshot,直接使用操作返回的页面状态即可。
❌ 错误做法:
browser_click → browser_snapshot → 分析 → browser_click → browser_snapshot → ...
✅ 正确做法:
browser_click → 从返回结果中获取页面状态 → browser_click → ...2. 避免不必要的 browser_wait_for
只在以下情况使用 browser_wait_for:
- 等待图片上传完成(
textGone="正在上传媒体") - 等待页面初始加载(极少数情况)
不要使用 browser_wait_for 来等待按钮或输入框出现 - 它们在页面加载完成后立即可用。
3. 并行执行独立操作
当两个操作没有依赖关系时,可以在同一个消息中并行调用多个工具:
✅ 可以并行:
- 填写标题 (browser_type) + 复制HTML到剪贴板 (Bash)
- 解析Markdown生成JSON + 生成HTML文件
❌ 不能并行(有依赖):
- 必须先点击create才能上传封面图
- 必须先粘贴内容才能插入图片4. 连续执行浏览器操作
每个浏览器操作返回的页面状态包含所有需要的元素引用。直接使用这些引用进行下一步操作:
# 理想流程(每步直接执行,不额外等待):
browser_navigate → 从返回状态找create按钮 → browser_click(create)
→ 从返回状态找上传按钮 → browser_click(上传) → browser_file_upload
→ 从返回状态找应用按钮 → browser_click(应用)
→ 从返回状态找标题框 → browser_type(标题)
→ 点击编辑器 → browser_press_key(Meta+v)
→ ...5. 准备工作前置
在开始浏览器操作之前,先完成所有准备工作:
- 解析 Markdown 获取 JSON 数据
- 生成 HTML 文件到 /tmp/
- 记录 title、cover_image、content_images 等信息
这样浏览器操作阶段可以连续执行,不需要中途停下来处理数据。
Step 1: Parse Markdown (Python)
Use parse_markdown.py to extract all structured data:
python ~/.claude/skills/x-article-publisher/scripts/parse_markdown.py /path/to/article.mdOutput JSON:
{
"title": "Article Title",
"cover_image": "/path/to/first-image.jpg",
"content_images": [
{"path": "/path/to/img2.jpg", "block_index": 5, "after_text": "context for debugging..."},
{"path": "/path/to/img3.jpg", "block_index": 12, "after_text": "another context..."}
],
"html": "<p>Content...</p><h2>Section</h2>...",
"total_blocks": 45
}Key fields:
block_index: The image should be inserted AFTER block element at this index (0-indexed)total_blocks: Total number of block elements in the HTMLafter_text: Kept for reference/debugging only, NOT for positioning
Save HTML to temp file for clipboard:
python parse_markdown.py article.md --html-only > /tmp/article_html.htmlStep 2: Open X Articles Editor
browser_navigate: https://x.com/compose/articles重要: 页面加载后会显示草稿列表,不是编辑器。需要:
- 等待页面加载完成: 使用
browser_snapshot检查页面状态 - 立即点击 "create" 按钮: 不要等待 "添加标题" 等编辑器元素,它们只有点击 create 后才出现
- 等待编辑器加载: 点击 create 后,等待编辑器元素出现
# 1. 导航到页面
browser_navigate: https://x.com/compose/articles
# 2. 获取页面快照,找到 create 按钮
browser_snapshot
# 3. 点击 create 按钮(通常 ref 类似 "create" 或带有 create 标签)
browser_click: element="create button", ref=<create_button_ref>
# 4. 现在编辑器应该打开了,可以继续上传封面图等操作注意: 不要使用 browser_wait_for text="添加标题" 来等待页面加载,因为这个文本只有在点击 create 后才出现,会导致超时。
If login needed, prompt user to log in manually.
Step 3: Upload Cover Image
- Click "添加照片或视频" button
- Use browser_file_upload with the cover image path (from JSON output)
- Verify image uploaded
Step 4: Fill Title
- Find textbox with "添加标题" placeholder
- Use browser_type to input title (from JSON output)
Step 5: Paste Text Content (Python Clipboard)
Copy HTML to system clipboard using Python, then paste:
# Copy HTML to clipboard
python ~/.claude/skills/x-article-publisher/scripts/copy_to_clipboard.py html --file /tmp/article_html.htmlThen in browser:
browser_click on editor textbox
browser_press_key: Meta+vThis preserves all rich text formatting (H2, bold, links, lists).
Step 6: Insert Content Images (Block Index Positioning)
关键改进: 使用 block_index 精确定位,而非依赖文字匹配。
定位原理
粘贴 HTML 后,编辑器中的内容结构为一系列块元素(段落、标题、引用等)。每张图片的 block_index 表示它应该插入在第 N 个块元素之后。
操作步骤
- 获取所有块元素: 使用 browser_snapshot 获取编辑器内容,找到 textbox 下的所有子元素
- 按索引定位: 根据
block_index点击对应的块元素 - 粘贴图片: 复制图片到剪贴板后粘贴
For each content image (from content_images array):
# 1. Copy image to clipboard (with compression)
python ~/.claude/skills/x-article-publisher/scripts/copy_to_clipboard.py image /path/to/img.jpg --quality 85# 2. Click the block element at block_index
# Example: if block_index=5, click the 6th block element (0-indexed)
browser_click on the element at position block_index in the editor
# 3. Paste image
browser_press_key: Meta+v
# 4. Wait for upload (use short time, returns immediately when done)
browser_wait_for textGone="正在上传媒体" time=2定位策略
在 browser_snapshot 返回的结构中,编辑器内容通常是:
textbox [ref=xxx]:
generic [ref=block0]: # block_index 0
- paragraph content
heading [ref=block1]: # block_index 1
- h2 content
generic [ref=block2]: # block_index 2
- paragraph content
...要在 block_index=5 后插入图片:
- 找到编辑器 textbox 下的第 6 个子元素(索引从0开始)
- 点击该元素
- 粘贴图片
注意: 每插入一张图片后,后续图片的实际位置会偏移。建议按 block_index 从大到小的顺序插入图片,这样先插入的图片不会影响后续图片的索引。
反向插入示例
如果有3张图片,block_index 分别为 5, 12, 27:
- 先插入 block_index=27 的图片
- 再插入 block_index=12 的图片
- 最后插入 block_index=5 的图片
这样每次插入都不会影响前面已经定位好的位置。
Step 7: Save Draft
- Verify content pasted (check word count indicator)
- Draft auto-saves, or click Save button if needed
- Click "预览" to verify formatting
- Report: "Draft saved. Review and publish manually."
Critical Rules
- NEVER publish - Only save draft
- First image = cover - Upload first image as cover image
- Rich text conversion - Always convert Markdown to HTML before pasting
- Use clipboard API - Paste via clipboard for proper formatting
- Block index positioning - Use block_index for precise image placement
- Reverse order insertion - Insert images from highest to lowest block_index
- H1 title handling - H1 is used as title only, not included in body
Supported Formatting
- H2 headers (## )
- Blockquotes (> )
- Code blocks (
...) - converted to blockquotes since X doesn't support<pre><code> - Bold text (**)
- Hyperlinks (text)
- Ordered lists (1. 2. 3.)
- Unordered lists (- )
- Paragraphs
Example Flow
User: "Publish /path/to/article.md to X"
# Step 1: Parse Markdown
python ~/.claude/skills/x-article-publisher/scripts/parse_markdown.py /path/to/article.md > /tmp/article.json
python ~/.claude/skills/x-article-publisher/scripts/parse_markdown.py /path/to/article.md --html-only > /tmp/article_html.html- Navigate to https://x.com/compose/articles
- Upload cover image (browser_file_upload for cover only)
- Fill title (from JSON:
title) - Copy & paste HTML:
Then: browser_press_key Meta+vpython ~/.claude/skills/x-article-publisher/scripts/copy_to_clipboard.py html --file /tmp/article_html.html - For each content image, in reverse order of block_index:
python copy_to_clipboard.py image /path/to/img.jpg --quality 85- Click block element at
block_indexposition - browser_press_key Meta+v
- Wait until upload complete
- Click block element at
- Verify in preview
- "Draft saved. Please review and publish manually."
Best Practices
为什么用 block_index 而非文字匹配?
- 精确定位: 不依赖文字内容,即使多处文字相似也能正确定位
- 可靠性: 索引是确定性的,不会因为文字相似而混淆
- 调试方便:
after_text仍保留用于人工核验
为什么用 Python 而非浏览器内 JavaScript?
- 本地处理更可靠: Python 直接操作系统剪贴板,不受浏览器沙盒限制
- 图片压缩: 上传前压缩图片 (--quality 85),减少上传时间
- 代码复用: 脚本固定不变,无需每次重新编写转换逻辑
- 调试方便: 脚本可单独测试,问题易定位
等待策略
关键理解: browser_wait_for 的 textGone 参数会在文字消失时立即返回,time 只是最大等待时间,不是固定等待时间。
- ❌ 保守等待:
time=5或time=10,如果上传只需2秒,剩余时间全浪费 - ✅ 短间隔轮询:
time=2,条件满足立即返回,最多等2秒
# 正确用法:短 time 值,条件满足立即返回
browser_wait_for textGone="正在上传媒体" time=2
# 错误用法:固定长时间等待
browser_wait_for time=5 # 无条件等待5秒,浪费时间原则: 不要预设"需要等多久",而是设置一个合理的最大值,让条件检测尽快返回。
图片插入效率
每张图片的浏览器操作从5步减少到2步:
- 旧: 点击 → 添加媒体 → 媒体 → 添加照片 → file_upload
- 新: 点击段落 → Meta+v
封面图 vs 内容图
- 封面图: 使用 browser_file_upload(因为有专门的上传按钮)
- 内容图: 使用 Python 剪贴板 + 粘贴(更高效)
