## What it does

The skill performs read-only checks directly on the Jetson target rather than a host workstation. It inspects `/proc/device-tree/model` to verify the hardware and exits immediately if the device string does not contain "Jetson". This baseline captures the software stack and power state before running performance runs.

Under the hood, it queries standard tools like `uname`, `uptime`, and `/etc/nv_tegra_release`, along with `nvpmodel -q` for power mode data. If `nvpmodel` is missing inside a container, the script prints a fallback label without breaking the report. The skill does not monitor thermal sensors, clock rates, or per-rail power consumption.

## Install

### Claude Code (native platform)

```bash
npx skills add NVIDIA/skills --skill jetson-print-device-info -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/jetson-print-device-info/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/jetson-print-device-info/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill jetson-print-device-info -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/jetson-print-device-info/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill jetson-print-device-info -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/jetson-print-device-info/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install NVIDIA/skills jetson-print-device-info
```

2. **Manually: put the files in place**

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill jetson-print-device-info -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/NVIDIA/skills --path skills/jetson-print-device-info
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/jetson-print-device-info/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill jetson-print-device-info -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/NVIDIA/skills/tree/HEAD/skills/jetson-print-device-info/SKILL.md

## When to use it
- capture a software and power baseline before performance tests
- verify L4T release details on a freshly flashed device
- check active nvpmodel power modes on Jetson hardware
- inspect kernel version and uptime via agent commands

## Example prompts
- Inspect this Jetson board and report its model, L4T release, and power mode.
- Capture the system baseline before we start regression benchmarks.
- Check the current OS version and nvpmodel setting on the target.

# jetson-print-device-info

Prints a concise summary of the Jetson device this skill runs on.

This skill is intended as a reference example for the `jetson-device-skills` repo and the NVIDIA-wide skills CI. It runs on the Jetson target (not the host PC) and performs read-only inspection — useful as a baseline capture before running performance tests.

## Purpose

Capture a baseline snapshot of a Jetson target's software stack and power mode before running performance, regression, or compatibility tests.

## When to use

- Starting a performance run and you want a captured baseline of the device's software stack and power mode.
- Verifying that a freshly flashed Jetson matches an expected L4T / JetPack version.

## Prerequisites

- Running on a Jetson target (not the host PC).
- Standard CLIs available: `tr`, `cat`, `uname`, `uptime`, `lsb_release` (or `/etc/os-release`).
- `nvpmodel` available for power mode (optional — skill falls back gracefully).

## Inputs

None. The skill reads only from the local Jetson filesystem and standard CLIs.

## Instructions

Run each step in order and print the captured values into the report shown under [Output format](#output-format).

1. **Capture** the module model and **validate** it is a Jetson target — exit early otherwise:
   ```bash
   # Device-tree strings are null-terminated, so strip NULs before printing.
   model=$(tr -d '\0' < /proc/device-tree/model 2>/dev/null)
   case "$model" in
     *Jetson*) ;;
     *) echo "Not running on a Jetson target (model: '${model:-unknown}')"; exit 1 ;;
   esac
   echo "$model"
   ```
2. **Extract** the L4T release header line — skip the rest of the file (long list of library SHAs):
   ```bash
   head -1 /etc/nv_tegra_release 2>/dev/null || echo "L4T release info not found"
   # Equivalent: grep -m1 '^# R' /etc/nv_tegra_release
   ```
3. **Run** `nvpmodel -q` and **join** its two output lines (`NV Power Mode: <name>` and the mode number) onto one line. `paste -sd` only uses the first char of its delimiter, so use `awk` to insert the literal ` / ` separator:
   ```bash
   nvpmodel -q 2>/dev/null | awk 'NR==1{a=$0; next} {print a" / "$0}' \
     || echo "nvpmodel not available"
   ```
4. **Print** the kernel version and uptime:
   ```bash
   uname -r
   uptime -p
   ```
5. **Print** the OS version (prefer `lsb_release`, fall back to `/etc/os-release`):
   ```bash
   lsb_release -ds 2>/dev/null || (. /etc/os-release && echo "$PRETTY_NAME") || echo "OS version not found"
   ```

## Output format

Print a short report with these sections, one line each where possible:

```text
Model:           <device-tree model string>
````
