Check EXTEND.md existence (priority order):

# 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 (Windows)

$xdg = if ($env:XDG_CONFIG_HOME) { $env:XDG_CONFIG_HOME } else { "$HOME/.config" }

Prerequisites

• Google Chrome or Chromium

• First run: log in to X manually (session saved)

If any check fails, provide fix guidance per item:

• Markdown file (.md) → X Article

Regular Posts

${BUN_X} {baseDir}/scripts/x-browser.ts "Hello!" --image ./photo.png

Parameters:

Note: Script opens browser with content filled in. User reviews and publishes manually.

Note: Script opens browser with content filled in. User reviews and publishes manually.

Quote an existing tweet with comment.

${BUN_X} {baseDir}/scripts/x-quote.ts https://x.com/user/status/123 "Great insight!"

Frontmatter: title, cover_image supported in YAML front matter.

Note: Script opens browser with article filled in. User reviews and publishes manually.

Post-Composition Check: The script automatically verifies after all images are inserted:

• Remaining XIMGPH_ placeholders in editor content
• Expected vs actual image count

If the check fails (warnings in output), alert the user with the specific issues before they publish.

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:

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
