Preferences (EXTEND.md)

Use Bash to check EXTEND.md existence (priority order):

# 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"

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
