Description
Detect unexpected system reboots and alert when the system comes back online. Tracks boot history and flags suspicious restarts.
Usage Guidance
This skill appears to do exactly what it claims: a local helper that records boot timestamps and signals reboots. It does not request network access or secrets. Before installing/running: (1) review and, if needed, adjust the default state/history paths; avoid running it as root to prevent accidental overwrites of sensitive files (the --state option can write to any path the process can write to); (2) ensure the host has the standard utilities the script uses (who, awk, uptime, stat, date); and (3) if you plan to run it from cron or a system-wide context, set explicit file paths and ownership so logs/state are written where you expect. Overall the skill is coherent and low-risk when used with those precautions.
Capability Analysis
Type: OpenClaw Skill
Name: reboot-checker
Version: 1.0.0
The 'reboot-checker' skill is a straightforward utility designed to monitor system boot times and detect restarts. The bash script (scripts/check-reboot.sh) uses standard system commands like 'who -b' and 'uptime' to track state locally in the user's home directory, with no evidence of data exfiltration, remote execution, or malicious intent.
Capability Assessment
Purpose & Capability
The name/description (detect unexpected reboots) matches the included script and instructions. Minor mismatch: metadata declares only 'bash' as a required binary, but the script also invokes who, awk, uptime, stat, date, and cut — common on most systems but not explicitly declared.
Instruction Scope
SKILL.md instructs running the bundled script, viewing history, and resetting state. The script only reads system boot time and writes to user-scoped state/history files; it does not contact external endpoints or read unrelated system data.
Install Mechanism
No install spec (instruction-only plus a script file). Nothing is downloaded or installed automatically; the script is executed locally. This is low-risk from an install perspective.
Credentials
No environment variables, credentials, or external tokens are requested. The script uses HOME (normal) and supports overriding file paths via --state / environment variables STATE_FILE/HISTORY_FILE, which is reasonable for flexibility.
Persistence & Privilege
The script persists state/history in ~/.reboot-check-state and ~/.reboot-check-history by default. Note: the --state option (or setting STATE_FILE env var) can point to any writable path and the script will overwrite that file, so running this as root could overwrite arbitrary files — use non-root contexts or carefully choose state paths.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install reboot-checker - After installation, invoke the skill by name or use
/reboot-checker - Provide required inputs per the skill's parameter spec and get structured output
