What is publish-x-article?

A tool for publishing Markdown articles to X’s long-form Articles editor. It converts headings, links, images, and other Markdown content into the editor’s supported formatting.

Use it to publish a Markdown file or URL as an X Article, including uploading a cover image and adapting unsupported elements.

It avoids reformatting an article by hand and handles content that X’s editor or subscription limits cannot represent directly.

publish-x-article — Skill for Claude Code by sugarforever

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add sugarforever/01coder-agent-skills --skill publish-x-article

Clone the repo

git clone --depth 1 https://github.com/sugarforever/01coder-agent-skills

Made for: Claude Code.

Or install 01coder-skills, the plugin that ships this one along with the rest of its 23 skills.

SkillSpector: 2 findings, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

medium Rogue Agent · line 173
Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00089	$0.05797
Opus 5.5	$0.00036	$0.02319
Sonnet 5.5	$0.00018	$0.01159
Haiku 4.5	$0.00009	$0.00580

Security

Grade A, and why

publish-x-article scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/copy_to_clipboard.py, scripts/parse_markdown.py, scripts/table_to_image.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 630 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Publish X Article

Publish Markdown content to X (Twitter) Articles editor, preserving formatting with rich text conversion. Automatically handles X Premium limitations by converting unsupported elements to images.

Credits

This skill is inspired by and based on wshuyi/x-article-publisher-skill. Thank you to the original author for the foundational work.

Interactive Setup: Ask Subscription Type

IMPORTANT: Before processing the article, ask the user about their X subscription type if not already known.

Prompt the User

Before publishing, I need to know your X subscription type to handle formatting correctly:

1. **X Premium** - Basic tier ($8/month)
2. **X Premium+** - Plus tier ($16/month)

Which subscription do you have? (Premium / Premium+)

For Chinese users:

在发布之前，我需要了解您的 X 订阅类型以正确处理格式：

1. **X Premium** - 基础版 ($8/月)
2. **X Premium+** - 高级版 ($16/月)

您使用的是哪个版本？(Premium / Premium+)

Remember the Answer

Once the user answers, remember their subscription type for the rest of the session. Don't ask again unless they explicitly want to change it.

X Subscription Feature Comparison

Feature	X Premium	X Premium+
H1 headers (`#`)	Title only	Title only
H2 headers (`##`)	Yes	Yes
H3+ headers (`###`, etc.)	No	Yes
Markdown tables	No	Yes
Mermaid diagrams	No	No (not supported by X)
Code blocks	Blockquotes	Blockquotes
Bold, italic, links	Yes	Yes
Lists	Yes	Yes
Blockquotes	Yes	Yes
Images	Yes	Yes

Pre-Processing Required by Subscription

X Premium (Basic):

Convert H3+ headers → H2 or bold
Convert tables → PNG images
Convert mermaid → PNG images

X Premium+ (Plus):

Keep H3+ headers as-is
Keep tables as-is (rendered natively)
Convert mermaid → PNG images (still not supported)

Prerequisites

Playwright MCP for browser automation
User logged into X with Premium subscription
Python 3.9+ with dependencies:
- macOS: pip install Pillow pyobjc-framework-Cocoa markdown
- Windows: pip install Pillow pywin32 clip-util markdown

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
