> Analyze [pi-agent](https://github.com/badlogic/pi-mono) session usage with the same reporting experience as <code>ccusage</code>.

## Quick Start

```bash
# Recommended - always include @latest
npx @ccusage/pi@latest --help
bunx @ccusage/pi@latest --help

# Alternative package runners
pnpm dlx @ccusage/pi
pnpx @ccusage/pi
```

### Recommended: Shell Alias

Since `npx @ccusage/pi@latest` is quite long to type repeatedly, we strongly recommend setting up a shell alias:

```bash
# bash/zsh: alias ccusage-pi='bunx @ccusage/pi@latest'
# fish:     alias ccusage-pi 'bunx @ccusage/pi@latest'

# Then simply run:
ccusage-pi daily
ccusage-pi monthly --json
```

> 💡 The CLI reads pi-agent session data from `~/.pi/agent/sessions/` (configurable via `PI_AGENT_DIR`).

## Common Commands

```bash
# Daily usage grouped by date (default command)
npx @ccusage/pi@latest daily

# Monthly usage grouped by month
npx @ccusage/pi@latest monthly

# Session-based usage
npx @ccusage/pi@latest session

# JSON output for scripting
npx @ccusage/pi@latest daily --json

# Custom pi-agent path
npx @ccusage/pi@latest daily --pi-path /path/to/sessions

# Filter by date range
npx @ccusage/pi@latest daily --since 2025-12-01 --until 2025-12-19
```

Useful environment variables:

- `PI_AGENT_DIR` – override the pi-agent sessions directory (defaults to `~/.pi/agent/sessions`)
- `LOG_LEVEL` – control log verbosity (0 silent … 5 trace)

## What is pi-agent?

[Pi-agent](https://github.com/badlogic/pi-mono) is an alternative Claude coding agent. It stores usage data in a similar JSONL format to Claude Code but in a different directory structure.

## Features

- 📊 **Daily/Monthly/Session Reports**: Same reporting options as ccusage
- 💵 **Accurate Cost Calculation**: Uses LiteLLM pricing database
- 📄 **JSON Output**: Export data in structured JSON format with `--json`
- 📱 **Compact Mode**: Use `--compact` flag for narrow terminals

## Data Source

Pi-agent session data is read from:

| Directory         | Default Path            |
| ----------------- | ----------------------- |
| Pi-agent sessions | `~/.pi/agent/sessions/` |
