## What it does

jetson-diagnostic reads the state of a running Jetson without changing its configuration. It can identify the SKU and L4T version, inspect RAM and swap, GPU activity, temperatures, power mode, disk use, candidate services, and memory-heavy processes.

\`scripts/snapshot.sh` returns an all-in-one JSON report. Use `scripts/mem_summary.sh` for a compact RAM, GPU and swap report, while `scripts/detect_jetson.sh` prints device identification fields. Reference files explain pasted `tegrastats` output and NvMap client data.

Run it on the Jetson host, or in an environment that can see host system paths and process data. This is diagnostic only: it does not change power modes, stop services, or install packages. NvMap details can be incomplete without root access.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill jetson-diagnostic -a claude-code
```

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install NVIDIA/skills jetson-diagnostic
```

2. **Manually: put the files in place**
- File: `.github/skills/jetson-diagnostic/SKILL.md`

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill jetson-diagnostic -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-diagnostic/SKILL.md

## When to use it
- identify a Jetson SKU and memory capacity
- find the process using the most RAM
- inspect thermal readings and GPU load sources
- check power mode and disk usage
- list active services for later action

## Example prompts
- Run `scripts/snapshot.sh` and summarize this Jetson's current state.
- Use `scripts/mem_summary.sh` to show RAM, GPU and swap usage.
- Explain this `tegrastats` line using the skill references.

# Jetson Diagnostic

A unified, agent-friendly view of a running Jetson device. Replaces the need to remember which of `tegrastats`, `jtop`, `procrank`, `/sys/kernel/debug/nvmap`, `nvpmodel`, `free`, `swapon`, `df`, and `systemctl list-units` produces which slice of the truth.

## Purpose

Capture a read-only health snapshot from the Jetson host so agents can answer device identity, memory, GPU, thermal, power, storage, and service-state questions using live data instead of guesses.

## When to use

Activate when the user asks:

- "What is this Jetson? What SKU? How much memory?"
- "What's running on this Jetson right now?"
- "Why is my Jetson slow / hot / out of memory?"
- "Give me a snapshot of GPU / CPU / power usage."
- "What does my tegrastats output mean?"
- "Which services are running that I could turn off?"
- The user has installed `jetson-memory-audit`, `jetson-headless-mode`, `jetson-inference-mem-tune`, `jetson-llm-benchmark`, `jetson-llm-serve`, or `jetson-package` and needs a baseline measurement before running them.

Do not use this skill to change power modes, drop caches, stop services, install packages, serve models, or tune inference flags. Report the observed state, then hand off to the action-oriented skill.

## Prerequisites

- Run on the Jetson host, or in a sandbox/container with host-visible Jetson system paths and process data.

## Available Scripts

| Script | Purpose | Arguments |
|--------|---------|-----------|
| `scripts/snapshot.sh` | Emits the all-in-one JSON snapshot for identity, memory, GPU, thermal, power, disk, top processes, and candidate services. | `--human`, `--tegra-secs N`, `--top-procs N`. |
| `scripts/mem_summary.sh` | Emits a compact human-readable RAM/GPU/swap summary. | `--short`, `--watch`, `--interval N`. |
| `scripts/detect_jetson.sh` | Exports or prints canonical Jetson SKU/generation/product-line fields for this repo. | No arguments. |

If your agent runtime supports `run_script`, use it to run `scripts/snapshot.sh` or `scripts/mem_summary.sh` and summarize the returned output. Otherwise run the scripts with `bash` from the repository root.

## Instructions

1. Run `scripts/snapshot.sh` for the all-in-one JSON view (preferred default).
2. For a quick human-readable memory line, run `scripts/mem_summary.sh`.
3. To explain a single tegrastats line the user has pasted, see `references/tegrastats-fields.md`.
4. To explain the NvMap clients output, see `references/nvmap-clients.md`.
