## What it does

This skill supports the TAO Optical Inspection model, which uses Siamese networks to compare component images with reference images. It covers training, evaluation, inference, and export. Training uses AutoML by default when the packaged schema and configuration template are available; a request to disable AutoML applies to that run.

Prepare `images.tar.gz` and a `dataset.csv` with `input_path`, `golden_path`, `label`, and `object_name` columns. The exact uppercase label `PASS` marks a non-defective item; any other non-empty label is treated as a defect. The path columns point to image directories. Be careful with capitalization: `pass` is classified as a defect.

Docker and `nvidia-container-toolkit` are required. TensorRT engine generation belongs to TAO Deploy, not the parent PyT container, so deploy actions use separate deployment instructions.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill tao-train-optical-inspection -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill tao-train-optical-inspection -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill tao-train-optical-inspection -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install NVIDIA/skills tao-train-optical-inspection
```

2. **Manually: put the files in place**
- File: `.github/skills/tao-train-optical-inspection/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill tao-train-optical-inspection -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/NVIDIA/skills --path skills/tao-train-optical-inspection
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill tao-train-optical-inspection -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/tao-train-optical-inspection/SKILL.md

## When to use it
- train a defect classifier on AOI images
- compare board captures with golden references
- evaluate a model against a test dataset
- run inference on new component images
- prepare a model for TAO Deploy

## Example prompts
- Train an Optical Inspection model on my AOI dataset with AutoML.
- Check `dataset.csv` and evaluate the model on the test images.
- Run Optical Inspection inference on these new board images.

# Optical Inspection

> **Standalone install?** If this session was not initialized by the TAO skill bank plugin, run the `tao-setup` skill first (host preflight, credentials, cross-skill discovery).

Optical inspection for defect detection using Siamese networks. Compares image pairs to detect manufacturing defects, anomalies, or quality issues.

Set train.pretrained_model_path for pretrained Siamese weights.

For TAO Deploy TensorRT actions (`gen_trt_engine`, TensorRT `evaluate`, and TensorRT `inference`), read `references/tao-deploy-optical-inspection.md` first. The parent PyT container does not expose `optical_inspection gen_trt_engine`; TensorRT engine generation is deploy-only. Deploy spec templates live in this skill's `references/` folder with the `spec_template_deploy_*.yaml` prefix.

## Dataclass Schemas

Generated TAO Core schemas are packaged in `schemas/<action>.schema.json`, with `schemas/manifest.json` listing available actions. Each generated schema also emits `references/spec_template_<action>.yaml` from the schema top-level `default` field. AutoML enablement is declared at the model layer in `references/skill_info.yaml` via `automl_enabled`. Runnable AutoML for an action requires `schemas/<action>.schema.json` and `references/spec_template_<action>.yaml` to exist and parse. Use the packaged selected-action schema for `automl_default_parameters`, `automl_disabled_parameters`, defaults, min/max bounds, enums, option weights, math conditions, dependencies, and popular parameters. Do not expect `~/tao-core` at runtime; maintainers regenerate schemas/templates before packaging the skill bank.
