## What it does

This skill launches an application under NVIDIA Nsight Graphics or attaches to a running PID, then triggers Graphics Capture or OpenGL Frame Debugger capture. It can capture GPU Trace data, export the results, and produce a summary of tables, metrics, frame budget, workload classification, and bottleneck hints.

\`replay analyze` processes `.ngfx-capture` files through `ngfx-replay`. It exports metadata, logs, captured log errors, and a replay performance report. Use `--json` in scripted flows; `doctor info` detects the available compatibility mode, while `doctor versions` lists detected installations.

NVIDIA Nsight Graphics must already be installed, and a Windows host is recommended. `.ngfx-gputrace` files may return `Invalid file header` on Nsight Graphics 2026.1.0, so `gpu-trace summarize` is the right path for exported GPU Trace tables.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add HKUDS/CLI-Anything --skill cli-anything-nsight-graphics -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add HKUDS/CLI-Anything --skill cli-anything-nsight-graphics -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add HKUDS/CLI-Anything --skill cli-anything-nsight-graphics -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install HKUDS/CLI-Anything cli-anything-nsight-graphics
```

2. **Manually: put the files in place**
- File: `.github/skills/cli-anything-nsight-graphics/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add HKUDS/CLI-Anything --skill cli-anything-nsight-graphics -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/HKUDS/CLI-Anything --path skills/cli-anything-nsight-graphics
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add HKUDS/CLI-Anything --skill cli-anything-nsight-graphics -a opencode
```

## When to use it
- check detected Nsight Graphics installations
- launch an application for frame capture
- attach Nsight to a running PID
- capture and export a GPU Trace
- analyze an existing `.ngfx-capture` file

## Example prompts
- “Run `cli-anything-nsight-graphics --json doctor info` and report the available compatibility mode.”
- “Capture a GPU Trace for `C:\Path\To\App.exe`, then export and summarize it.”
- “Analyze `D:\captures\frame.ngfx-capture` and write the results to `D:\analysis`.”

# Nsight Graphics CLI Skill

Command-line orchestration of official NVIDIA Nsight Graphics activities.

## Capabilities

- Probe installed Nsight binaries and compatibility mode
- Launch an application detached under Nsight
- Attach Nsight to a running PID
- Trigger Graphics Capture or OpenGL Frame Debugger capture
- Trigger GPU Trace capture, auto-export, and summarize
- Analyze existing `.ngfx-capture` files through `ngfx-replay`
- Report clear compatibility diagnostics for `.ngfx-gputrace` inputs
- Trigger Generate C++ Capture

## Commands

### doctor

```bash
cli-anything-nsight-graphics --json doctor info
cli-anything-nsight-graphics --json doctor versions
cli-anything-nsight-graphics --nsight-path "C:\Path\To\Nsight Graphics 2024.2\host\windows-desktop-nomad-x64" --json doctor info
```

### launch

```bash
cli-anything-nsight-graphics launch detached --activity "Graphics Capture" --exe "C:\Path\To\App.exe"
cli-anything-nsight-graphics launch attach --activity "Graphics Capture" --pid 12345
```

### frame capture

```bash
cli-anything-nsight-graphics --output-dir D:\captures frame capture ^
  --exe "C:\Path\To\App.exe" ^
  --wait-frames 10
```

### GPU Trace

```bash
cli-anything-nsight-graphics --output-dir D:\traces gpu-trace capture ^
  --exe "C:\Path\To\App.exe" ^
  --start-after-ms 1000 ^

```

## Agent Notes

- Prefer `doctor info` first to discover the available compatibility mode.
- Use `doctor versions` to list detected installs when multiple Nsight Graphics versions exist.
- Use `--nsight-path` to force a specific install directory or `ngfx.exe`.
- Use `--json` for programmatic workflows.
- Prefer `gpu-trace capture --auto-export --summarize` for one-step performance
  triage. The summary includes exported table inventory, metric inventory,
