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.

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 →

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 | $0.00044 | $0.02899 |
| Sonnet 5 | $0.00018 | $0.01159 |
| Haiku 4.5 | $0.00009 | $0.00580 |
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 10d ago.
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
- macOS:
- diagram-to-image skill (for converting tables/mermaid to PNG via diagramless.xyz API)
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.
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.

publish-x-article is a skill published in the GitHub repository sugarforever/01coder-agent-skills (134 stars, last pushed 2mo ago), licensed MIT. It adds 89 tokens to every session and 5,797 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
