X Publish

Publish tweets and threads to X draft using Playwright browser automation.

Prerequisites

  • Playwright MCP for browser automation
  • User logged into X (Twitter)
  • Python 3.9+ with dependencies:
    • macOS: pip install Pillow pyobjc-framework-Cocoa
    • Windows: pip install Pillow pywin32

Critical Rules

  1. NEVER auto-publish - Only save to draft
  2. User must be logged in - Prompt to login if not
  3. Verify content before saving - Double-check tweet text

Content Types

Short Tweet

Single tweet ≤280 characters

Thread

Multiple tweets connected (3-10 tweets)

Scripts

copy_to_clipboard.py

Copy text to system clipboard for paste operation:

bash
# Copy text to clipboard
python scripts/copy_to_clipboard.py text "Tweet content here"

# Copy from file
python scripts/copy_to_clipboard.py text --file /tmp/tweet.txt

Workflow

Short Tweet

Step 1: Prepare Content

bash
# Save tweet to temp file
echo "Tweet content" > /tmp/tweet.txt

# Copy to clipboard
python scripts/copy_to_clipboard.py text --file /tmp/tweet.txt

Step 2: Open Compose

browser_navigate: https://x.com/compose/post

Step 3: Paste Content

browser_snapshot → Find tweet textbox
browser_click: textbox
browser_press_key: Meta+v

Step 4: Save Draft

browser_click: X (close button)
browser_click: "Save" or "保存" in dialog

Step 5: Verify

Report: "Draft saved. Please review at https://x.com/compose/drafts"

Thread

Step 1: Prepare Content Parse thread into individual tweets:

### 1/5
First tweet content...

### 2/5
Second tweet content...

Step 2: Open Compose

browser_navigate: https://x.com/compose/post

Step 3: Add First Tweet

bash
python scripts/copy_to_clipboard.py text "First tweet content"

browser_click: textbox
browser_press_key: Meta+v

Step 4: Add More Tweets For each additional tweet:

browser_click: "Add another post" / "添加" button
browser_press_key: Meta+v (after copying next tweet)

Step 5: Save Draft

browser_click: X (close button)
browser_click: "Save" in dialog

Step 6: Verify

Report: "Thread draft saved ({n} tweets). Review at https://x.com/compose/drafts"

Efficiency Guidelines

Avoid Unnecessary Waits

❌ browser_snapshot after every action
✅ Use action return values for next step

Parallel Preparation

✅ Prepare all tweet content before browser operations
✅ Copy to clipboard while navigating

Sequential Execution

Navigate → Paste first tweet → Add tweet → Paste → ... → Save

Element References

Common elements in X compose:

Element Description Typical ref pattern
Tweet textbox Main input area textbox with "What's happening"
Add tweet button "+" or "添加" button near compose area
Close button X icon button top-left
Save draft In close dialog "Save" / "保存" button
Drafts link View saved drafts link to /compose/drafts
