## Overview

The Phoenix CLI now supports **datasets**, **experiments**, and **annotations**. You can pull evaluation data, experiment results, and human feedback directly into your terminal or pipe them into AI coding assistants.

```bash theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
# List available datasets
px datasets

# Fetch dataset examples
px dataset <dataset-name>

# Export experiment results
px experiments --dataset <dataset-name> ./experiments/

# Get experiment details
px experiment <experiment-id> --format json

# Include annotations in traces
px traces --limit 10 --include-annotations
```

## Common Workflows

### Analyze Dataset Examples

Pull test cases for review:

```bash theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
# Get all examples from a dataset
px dataset <dataset-name> --format raw --no-progress | \
  jq '.examples[] | {input, output}'

# Filter by split (if dataset has splits defined)
px dataset <dataset-name> --split train --format raw --no-progress | \
  jq '.examples[]'
```

### Review Experiment Results

Check evaluation results:

```bash theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
# Get experiment runs with their inputs and outputs
px experiment <experiment-id> --format raw --no-progress | \
  jq '.[] | {input, output, latency_ms, trace_id}'

# Find runs with annotations
px experiment <experiment-id> --format raw --no-progress | \
  jq '.[] | select(.annotations | length > 0)'
```

### Use Annotations

Access human feedback on traces:

```bash theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
# Get traces with annotations
px traces --include-annotations --limit 50 --format raw | \
  jq '.[] | select(.spans[].annotations != null)'
```

### Export for Analysis

Save data to files for further processing:

```bash theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
# Export traces to directory
px traces --include-annotations --limit 100 ./production-samples/

# Export experiments to directory
px experiments --dataset <dataset-name> ./all-experiments/

# Filter examples with jq
px traces --include-annotations --format raw --no-progress | \
  jq '.[] | select(.spans[].annotations[] | select(.name == "quality" and .score >= 4))'
```

## Dataset and Experiment Commands

### Datasets

```bash theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
# List all datasets with metadata
px datasets --format json

# Fetch dataset with specific splits
px dataset <dataset-name> --split train --split validation

# Get specific version
px dataset <dataset-name> --version <version-id>
```

### Experiments

```bash theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
# List experiments for a dataset
px experiments --dataset <dataset-name>

# Export all experiment data
px experiments --dataset <dataset-name> ./experiments/

# Fetch single experiment with full details
px experiment <experiment-id> --format raw
```

### Annotations

```bash theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
# Include annotations in any trace command
px traces --include-annotations --limit 10

# Get specific trace with annotations
px trace <trace-id> --include-annotations
```

## Example: Reviewing Experiment Results

Get data from an experiment and dataset:

```bash theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
# Export experiment runs to a file
px experiment <experiment-id> --format raw --no-progress > experiment-runs.json

# Extract inputs and outputs
jq '.[] | {input, output, latency_ms}' experiment-runs.json > run-summary.json

# Export dataset examples
px dataset <dataset-name> --format raw --no-progress | \
  jq '.examples[] | {input, output}' \
  > dataset-examples.json
```

You can then ask an AI assistant to review the experiment results or analyze patterns in the dataset.

## Installation

```bash theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
npm install -g @arizeai/phoenix-cli
```

Or run directly:

```bash theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
npx @arizeai/phoenix-cli datasets
```

## Upgrading

If you already have the CLI installed, upgrade to 0.2.0 or later:

```bash theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
npm update -g @arizeai/phoenix-cli
```

Check your version:

```bash theme={"theme":{"light":"github-light-default","dark":"github-dark-default"}}
px --version
```
