Dgx Spark Temperature

SKILL.md

# dgx-spark-temperature

Read hardware temperature sensors on the DGX Spark via SNMP.

## When to use

- User asks for body temperature, DGX Spark temp, hardware temps, how hot things are running
- Any temperature/hardware health check request for the DGX Spark

## How to use

Run `exec` with:
```
bash <workspace>/skills/dgx-spark-temperature/check_temperature.sh
```

The script uses:
- `snmpwalk -v2c -c licpub dgx-spark1.fiber.house 1.3.6.1.4.1.2021.13.16.2.1`
- Parses LM-SENSORS MIB table: `lmTempSensorsIndex`, `lmTempSensorsDevice`, `lmTempSensorsValue`
- Values are in milliCelsius — divide by 1000 for °C

## Sensor mapping (16 sensors)
