English | 中文

The Problem

If you're used to writing in Markdown, publishing to X Articles is a painful process:

Pain Point	Description
Format Loss	Copy from Markdown editor → Paste to X → All formatting gone
Manual Formatting	Set each H2, bold, link manually — 15-20 min per article
Tedious Image Upload	5 clicks per image: Add media → Media → Add photo → Select → Wait
Position Errors	Hard to remember where each image should go

Time Comparison

Task	Manual	With This Skill
Format conversion	15-20 min	0 (automatic)
Cover image	1-2 min	10 sec
5 content images	5-10 min	1 min
Total	20-30 min	2-3 min

10x efficiency improvement

The Solution

This skill automates the entire publishing workflow:

Markdown File
     ↓ Python parsing
Structured Data (title, images with block_index, HTML)
     ↓ Playwright MCP
X Articles Editor (browser automation)
     ↓
Draft Saved (never auto-publishes)

Key Features

• Rich Text Paste: Convert Markdown to HTML, paste via clipboard — all formatting preserved
• Block-Index Positioning (v1.1): Precise image placement using element indices, not text matching
• Reverse Insertion: Insert images from highest to lowest index to avoid position shifts
• Smart Wait Strategy: Conditions return immediately when met, no wasted wait time
• Safe by Design: Only saves as draft, never publishes automatically

What's New in v1.1.0

Feature	Before	After
Image positioning	Text matching (fragile)	Block index (precise)
Insertion order	Sequential	Reverse (high→low)
Wait behavior	Fixed delay	Immediate return on condition

Why Block-Index?

Previously, images were positioned by matching surrounding text — this failed when:

• Multiple paragraphs had similar content
• Text was too short to be unique

Now, each image has a block_index indicating exactly which block element it follows. This is deterministic and reliable.
