Countdown Timer - 倒计时助手

This skill appears to be a simple local countdown/timer assistant, but review a few things before installing: - Confirm where data will be stored: SKILL.md claims ~/.openclaw/workspace/..., but the code writes 'countdowns.json' next to the Python file. Decide which location is acceptable and update code or instructions accordingly. - Reminders/notifications are described in the docs but not implemented as network push or system notifications in the provided code. If you expect push notifications or system integrations, ask the author for details or implement a safe notification channel yourself. - The code contains placeholder logic (e.g., add_countdown currently sets a fixed target date), so test with non-critical data first and inspect/modify the code if you want correct parsing/behavior. - Because the source is 'unknown', only grant this skill permission to write within a dedicated directory you control. If you are not comfortable with running included scripts from an unknown author, review the code locally or run it in a sandboxed environment before enabling it for your agent.
