# Annotate — Annotation Reference

Quick-reference skill for code annotation, type hints, documentation strings, and data labeling.

## When to Use

- Adding type annotations to Python, TypeScript, or Java code
- Writing JSDoc, docstrings, or Javadoc documentation
- Labeling datasets for machine learning training
- Using git annotate/blame for code archaeology
- Understanding decorator/annotation patterns in frameworks

## Commands

### `intro`

```bash
scripts/script.sh intro
```

Overview of annotation types — code, data, and metadata annotations.

### `types`

```bash
scripts/script.sh types
```

Type annotations — Python type hints, TypeScript types, Java generics.

### `docstrings`

```bash
scripts/script.sh docstrings
```

Documentation annotations — JSDoc, Python docstrings, Javadoc, XML comments.

### `decorators`

```bash
scripts/script.sh decorators
```

Decorator/annotation patterns — Python decorators, Java annotations, TypeScript decorators.

### `labeling`

```bash
scripts/script.sh labeling
```

Data labeling for ML — annotation types, tools, quality control, and formats.

### `git`

```bash
scripts/script.sh git
```

Git annotation — blame, annotate, log, and code archaeology techniques.

### `standards`

```bash
scripts/script.sh standards
```

Annotation standards — OpenAPI, JSON Schema, GraphQL descriptions, YAML comments.

### `best`

```bash
scripts/script.sh best
```

Annotation best practices — when to annotate, what to skip, and maintenance.

### `help`

```bash
scripts/script.sh help
```

### `version`

```bash
scripts/script.sh version
```

## Configuration

| Variable | Description |
|----------|-------------|
| `ANNOTATE_DIR` | Data directory (default: ~/.annotate/) |
