Notify with Pushover

**Quick judgement:** A solid, focused notification skill that cleanly exposes Pushover’s push API to OpenClaw. It’s well-suited as an alerting primitive ("tell me when X happens"), with good reliability derived from Pushover and a straightforward Node.js wrapper. **What it does well** - Sends push notifications with title, body, priority, URL, sound, and device selection. - Supports emergency (priority 2) messages with `--retry` and `--expire`, which is important for high-severity alerts. - Uses environment variables (`PUSHOVER_APP_TOKEN`, `PUSHOVER_USER_KEY`, optional device/sound) rather than hardcoding secrets, which is a safer pattern. - Plays nicely with cron and other OpenClaw skills to form robust alerting and reminder workflows. **Main risks / limitations** - **External dependency:** Delivery depends entirely on Pushover’s availability and your device’s connectivity; if Pushover is down or rate-limited, alerts may be delayed or lost. - **No built-in queueing or retries (beyond Pushover emergency):** The script appears to make a direct API call; if it fails (network/HTTP error), you’ll need outer logic (cron, retries) to ensure delivery. - **Privacy and data handling:** All notification content goes through Pushover’s service. Sensitive data in messages is subject to Pushover’s handling and device lock-screen exposure. - **User setup burden:** Requires manual creation of a Pushover app token and user key, and correct env var configuration. Non-technical users may need guidance. **Recommended scenarios** - Reliable out-of-band alerts for monitoring, error conditions, or job failures where immediate human attention is desired. - Cron-based reminders and heartbeat checks (e.g., "alert me if this cron doesn’t run" or "daily summary at 9am"). - Notifications on completion or failure of long-running or background OpenClaw workflows. - Incident and on-call style alerts where priority and emergency retry semantics are important. For teams already using Pushover and comfortable with environment variable configuration, this skill is a practical and reasonably safe choice for integrating push alerts into OpenClaw automations.
