# Post to X (Twitter)

Posts text, images, videos, and long-form articles to X via real Chrome browser (bypasses anti-bot detection).

## 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) |
| `scripts/x-video.ts` | Video posts (text + video) |
| `scripts/x-quote.ts` | Quote tweet with comment |
| `scripts/x-article.ts` | Long-form article publishing (Markdown) |
| `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 |

## Preferences (EXTEND.md)

Check EXTEND.md existence (priority order):

```bash
# macOS, Linux, WSL, Git Bash
test -f .baoyu-skills/baoyu-post-to-x/EXTEND.md && echo "project"
test -f "${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-post-to-x/EXTEND.md" && echo "xdg"
test -f "$HOME/.baoyu-skills/baoyu-post-to-x/EXTEND.md" && echo "user"
```

```powershell
# PowerShell (Windows)
if (Test-Path .baoyu-skills/baoyu-post-to-x/EXTEND.md) { "project" }
$xdg = if ($env:XDG_CONFIG_HOME) { $env:XDG_CONFIG_HOME } else { "$HOME/.config" }
if (Test-Path "$xdg/baoyu-skills/baoyu-post-to-x/EXTEND.md") { "xdg" }
if (Test-Path "$HOME/.baoyu-skills/baoyu-post-to-x/EXTEND.md") { "user" }
```

**EXTEND.md Supports**: Default Chrome profile

## Prerequisites

- Google Chrome or Chromium
- `bun` runtime
- First run: log in to X manually (session saved)

## Pre-flight Check (Optional)

Before first use, suggest running the environment check. User can skip if they prefer.

```bash
${BUN_X} {baseDir}/scripts/check-paste-permissions.ts
```

Checks: Chrome, profile isolation, Bun, Accessibility, clipboard, paste keystroke, Chrome conflicts.

**If any check fails**, provide fix guidance per item:

| Check | Fix |
|-------|-----|
| Chrome | Install Chrome or set `X_BROWSER_CHROME_PATH` env var |
| Profile dir | Shared profile at `baoyu-skills/chrome-profile` (see CLAUDE.md Chrome Profile section) |
| Bun runtime | `brew install oven-sh/bun/bun` (macOS) or `npm install -g bun` |
| Accessibility (macOS) | System Settings → Privacy & Security → Accessibility → enable terminal app |
| Clipboard copy | Ensure Swift/AppKit available (macOS Xcode CLI tools: `xcode-select --install`) |
| Paste keystroke (macOS) | Same as Accessibility fix above |
| Paste keystroke (Linux) | Install `xdotool` (X11) or `ydotool` (Wayland) |

## Troubleshooting

### Chrome debug port not ready

If a script fails with `Chrome debug port not ready` or `Unable to connect`, kill existing Chrome CDP instances first, then retry:

```bash
pkill -f "Chrome.*remote-debugging-port" 2>/dev/null; pkill -f "Chromium.*remote-debugging-port" 2>/dev/null; sleep 2
```

**Important**: This should be done automatically — when encountering this error, kill Chrome CDP instances and retry the command without asking the user.

## Notes

- First run: manual login required (session persists)
- All scripts only fill content into the browser, user must review and publish manually
- Cross-platform: macOS, Linux, Windows

## Extension Support

Custom configurations via EXTEND.md. See **Preferences** section for paths and supported options.
