## What it does

The skill executes end-to-end calibration on four synthetic warehouse cameras from `assets/sdg_08_2_sample_data_010926.zip` against an AutoMagicCalib microservice. The bundled `run_sample_calibration.py` script probes ports 8000 through 8009 for an active `/v1/ready` endpoint and creates a fresh project for the run. Because the sample data includes ground truth, the process outputs L2 distance and reprojection error metrics directly.

This skill handles only the bundled sample archive. It will fail on custom video paths or RTSP feeds because those require separate skills. If the backend is offline, the agent halts and points to `amc-setup-calibration-stack` instead of fabricating metrics.

Running the script requires Python 3 with the `requests` library installed via pip. It attempts VGGT refinement automatically whenever the project reports `vggt_state: READY`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill amc-run-sample-calibration -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill amc-run-sample-calibration -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill amc-run-sample-calibration -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install NVIDIA/skills amc-run-sample-calibration
```

2. **Manually: put the files in place**
- File: `.github/skills/amc-run-sample-calibration/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**

npx skills add NVIDIA/skills --skill amc-run-sample-calibration -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/NVIDIA/skills --path skills/amc-run-sample-calibration
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill amc-run-sample-calibration -a opencode
```

### Claude.ai

**Claude.ai**

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/amc-run-sample-calibration/SKILL.md

## When to use it
- verify the AutoMagicCalib microservice deployment
- extract bundled synthetic camera sample archives idempotently
- run end-to-end calibration without tuning parameters
- compute L2 distance and reprojection error against ground truth
- test optional VGGT refinement when ready

## Example prompts
- test sample dataset on the running AMC microservice
- verify AMC install with the bundled warehouse data
- run sample calibration and report evaluation metrics

# Skill: Calibrate Sample Dataset

## When to Use This Skill

Activate this skill when the user wants to sanity-check a running AMC stack with the bundled sample dataset. Typical prompts:

- "test the sample dataset" / "run sample calibration"
- "verify AMC install"
- "launch and test" (chain with `amc-setup-calibration-stack` if the MS isn't already running)

**Do NOT use this skill when:**

- The user references their own video paths (e.g. `/data/videos/`, `cam_*.mp4` not from the bundled zip) — route to `amc-run-video-calibration`.
- The user provides live RTSP streams or `rtsp://...` URLs — route to `amc-run-rtsp-calibration`.
- This skill is exclusively for `assets/sdg_08_2_sample_data_010926.zip`.

Prerequisite: AMC microservice running on a port in 8000-8009. If no backend is detected, delegate to `amc-setup-calibration-stack` first.

If execution cannot proceed in the current environment (no backend, missing sample data, etc.), surface the blocker AND describe the expected workflow + API sequence concisely so the user understands what will run once prerequisites are met. Do not fabricate calibration outputs, evaluation metrics, or trajectories.

## Overview

Run a full calibration on the bundled sample dataset (`sdg_08_2_sample_data_010926.zip`, 4 synthetic warehouse cameras with ground truth) against a running AutoMagicCalib microservice. Useful for verifying that a freshly-launched stack works end-to-end before throwing real data at it.

The sample includes GT, so the run produces evaluation metrics (L2 distance, reprojection error) — no calibration parameter tuning needed.

## Prerequisites

- [ ] AMC microservice running (follow `skills/amc-setup-calibration-stack/SKILL.md` if not)
- [ ] Sample zip present at `assets/sdg_08_2_sample_data_010926.zip`
- [ ] Python 3 with `requests` installed, or use the Swagger UI path below
  - Install it explicitly before running the script: `python3 -m pip install requests`
  - If `pip` is unavailable, install your distro's Python packaging support first

## Instructions

**"launch AMC and test sample dataset" (or similar):**
```
