What is baoyu-post-to-x?

A tool for publishing posts and long-form articles on X, formerly known as Twitter, through a real web browser.

Use it to publish regular text posts with images or videos, or to publish longer Markdown-based X Articles.

It handles the browser steps needed to publish content on X instead of requiring you to post each item manually. The input does not specify how it handles account access.

baoyu-post-to-x — Skill for Claude Code by JimLiu

About the project

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 MCP Rug Pull · line 31
npx commands without a version suffix (e.g. @1.0.0) create a rug-pull risk if the upstream server is compromised and publishes a malicious update.

Fix: Pin the version: npx @scope/[email protected]
medium Excessive Agency · line 324
Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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	$0.00095	$0.04185
Opus 5	$0.00048	$0.02093
Sonnet 5	$0.00019	$0.00837
Haiku 4.5	$0.00010	$0.00419

Security

Grade A, and why

baoyu-post-to-x 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 13d ago.

The scan reads SKILL.md. This mod also ships 11 executable files (scripts/check-paste-permissions.ts, scripts/copy-to-clipboard.ts, scripts/md-to-html.test.ts, …), 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 — 336 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Post to X (Twitter)

Posts text, images, videos, and long-form articles to X via a real Chrome browser.

In Codex, do not conflate these browser paths:

Codex Chrome plugin / @chrome / Chrome Extension: use the bundled chrome:Chrome skill and its Node REPL browser client. This is required whenever the user says "Codex Chrome plugin", "Codex 自带的 Chrome 插件", @chrome, or similar.
Chrome Computer Use: use mcp__computer_use__.* against the visible Google Chrome UI only when the user asks for Computer Use or no Chrome-plugin preference is stated and Computer Use is available.
CDP script mode: use only as a fallback when the selected mode is unavailable or the user explicitly asks for CDP/script mode.

Script Directory

Important: All scripts are located in the scripts/ subdirectory of this skill.

Agent Execution Instructions:

Determine this SKILL.md file's directory path as {baseDir}
Script path = {baseDir}/scripts/<script-name>.ts
Replace all {baseDir} in this document with the actual path
Resolve ${BUN_X} runtime: if bun installed → bun; if npx available → npx -y bun; else suggest installing bun

Script Reference:

Script	Purpose
`scripts/x-browser.ts`	Regular posts (text + images), CDP fallback
`scripts/x-video.ts`	Video posts (text + video), CDP fallback
`scripts/x-quote.ts`	Quote tweet with comment, CDP fallback
`scripts/x-article.ts`	Long-form article publishing (Markdown), CDP fallback
`scripts/md-to-html.ts`	Markdown → HTML conversion
`scripts/copy-to-clipboard.ts`	Copy content to clipboard
`scripts/paste-from-clipboard.ts`	Send real paste keystroke
`scripts/check-paste-permissions.ts`	Verify environment & permissions

Execution Mode Selection (Required)

Choose exactly one mode before interacting with X:

If the user explicitly asks for the Codex Chrome plugin, @chrome, the Chrome extension, or "Codex 自带的 Chrome 插件", use Codex Chrome Plugin Mode. Do not call Computer Use first.
If the user explicitly asks for Chrome Computer Use, use Chrome Computer Use Mode. Do not fall back to CDP, Playwright, the in-app Browser, or the Chrome plugin without telling the user and getting approval.
If the user explicitly asks for CDP/script mode, use CDP Script Mode.
Otherwise, prefer Chrome Computer Use Mode. For Markdown X Articles with local content images, use the tested X editor flow: insert each body image from the toolbar (Insert -> Media -> dialog icon button Add photos or video) at its placeholder, then delete the placeholder text. Use CDP Script Mode only when the selected browser-control mode is unavailable or the UI upload/selection flow is unreliable.

What ships with it

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.
