# Check project-level first
test -f .baoyu-skills/baoyu-post-to-x/EXTEND.md && echo "project"
# Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)
test -f "$HOME/.baoyu-skills/baoyu-post-to-x/EXTEND.md" && echo "user"

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 | Ensure ~/.local/share/x-browser-profile is writable |
| Bun runtime | curl -fsSL https://bun.sh/install | bash |
| 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 |

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
