# 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**:
1. Determine this SKILL.md file's directory path as `{baseDir}`
2. Script path = `{baseDir}/scripts/<script-name>.ts`
3. Replace all `{baseDir}` in this document with the actual path
4. 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:

1. 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.
2. 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.
3. If the user explicitly asks for CDP/script mode, use **CDP Script Mode**.
4. 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.

Never use the in-app Browser for X publishing workflows.

## Codex Chrome Plugin Mode

Use this mode whenever the user requests the Codex Chrome plugin, `@chrome`, or the Chrome Extension path. This uses the user's real Chrome profile and X login through the bundled Chrome plugin, not Computer Use and not CDP.

**Setup**
1. Load the `chrome:Chrome` skill before browser work.
2. Use `tool_search` for `node_repl js` if the Node REPL `js` tool is not already visible.
3. Initialize the Chrome browser client exactly as the Chrome skill specifies, then run a lightweight call such as `browser.user.openTabs()` to verify the extension connection.
4. If the first lightweight call fails, wait 2 seconds and retry once. If it still fails, follow the Chrome skill's extension checks and recovery steps. If checks pass but communication still fails, ask the user before opening a new Chrome window. Do not switch to Computer Use or CDP silently.

**General rules**
- Use the Chrome plugin's `browser.tabs.*`, `tab.playwright.*`, `tab.cua.*`, and file chooser APIs for X UI actions.
- Shell commands are allowed for Markdown preprocessing and rich-HTML clipboard preparation. For X Article body images, do not rely on image clipboard paste; use the editor's `Insert` -> `Media` upload flow.
- If a file upload fails with `Not allowed`, tell the user: `To enable file upload, go to chrome://extensions in Chrome, click Details under the Codex extension, and enable "Allow access to file URLs." See https://developers.openai.com/codex/app/chrome-extension#upload-files for details.`
- If the Chrome plugin reports `native pipe is closed`, retry the lightweight browser call once after 2 seconds, then run the Chrome skill health checks. If Chrome is running, the extension is enabled, and the native host manifest is correct, ask permission to open a new Chrome window and retry. Do not keep sending browser actions through the broken pipe.
- Never click `Publish`, `Post`, or any externally visible submit action without explicit final confirmation from the user in the current conversation.

**X Articles**
1. Convert Markdown and keep the image map:
   ```bash
   ${BUN_X} {baseDir}/scripts/md-to-html.ts article.md --save-html /tmp/x-article-body.html > /tmp/x-article.json
   ```
2. Read the JSON output for `title`, `coverImage`, and `contentImages` (`placeholder` → `localPath`).
3. Open or create the article draft at `https://x.com/compose/articles`.
4. Upload the cover with the Chrome plugin file chooser flow. If upload is blocked by extension permissions, stop and report the exact permission fix above.
5. Fill the title, then copy rich HTML:
   ```bash
   ${BUN_X} {baseDir}/scripts/copy-to-clipboard.ts html --file /tmp/x-article-body.html
   ```
6. Paste into the article body with a real paste keystroke through the Chrome plugin. On macOS use `Meta+V`.
7. Verify the editor text contains the article body and `XIMGPH_` placeholders. Do not rely on `tab.clipboard.readText()` as proof of the system clipboard after shell clipboard writes; on macOS verify with `pbpaste` if needed.
8. For each `contentImages` item in placeholder order:
   - Locate the visible placeholder text (`XIMGPH_N`) and click i
