Pi Health

Raspberry Pi health monitor. Check CPU temperature, throttling status, voltage levels, memory/disk usage, fan RPM, overclock detection, and power issues. Use when monitoring Pi health, diagnosing thermal throttling, checking for under-voltage, or verifying system stability on any Raspberry Pi (Pi 3/4/5, arm64/armhf).

Security Scan

The included script does exactly what the skill description says (local Raspberry Pi health checks) and requests no external credentials, network access, or unusual installs.

Purpose & Capability

The name/description (Pi health monitor) matches the provided files: SKILL.md instructs running scripts/health.sh and the script reads CPU temp, throttling, voltages, memory/disk, fan, overclock and dmesg for power events. Nothing requested (no env vars, no installs) is unrelated to the stated purpose.

Instruction Scope

SKILL.md simply instructs running the bundled script. The script reads standard local system paths (/sys, /proc, /boot, dmesg), invokes expected utilities (vcgencmd, free, df) if present, and prints results. Those reads are appropriate for a local health check; there are no instructions to collect or transmit data externally.

Install Mechanism

There is no install spec — this is instruction-only with an included script. Nothing is downloaded or written to disk by an installer, so install risk is low.

Credentials

The skill requests no environment variables, credentials, or config paths beyond reading local system files needed for monitoring. This is proportionate to the tool's purpose.

Persistence & Privilege

The skill does not request always:true, does not modify other skills or system configuration, and does not persist credentials. It only runs a read-only health-check script (no writes or daemon installation).

Assessment

This skill is coherent and the included script matches the description. It performs only local reads (sysfs, /proc, /boot/config.txt, dmesg) and runs standard utilities if available; it does not contact the network or require secrets. Before running, note that some outputs (dmesg, certain sysfs files) may require sufficient permissions and some tools (vcgencmd) are optional. Because the source/homepage is unknown, you can manually inspect scripts/health.sh (it is included) before executing. If you will run it on a production Pi, consider running it interactively (not as an always-on autonomous skill) and review whether you need root privileges for complete output.

Run the health check script:

bash scripts/health.sh

Exit Codes

• 0 — Healthy (all checks passed)
• 1 — Warnings (non-critical issues)
• 2 — Critical (needs immediate attention)

Requirements

• Raspberry Pi OS (Bookworm or later)
• vcgencmd (optional but recommended — comes with libraspberrypi-bin)
