Local-first usage reports for AI coding agents.

`agentusage` reads local agent history, normalizes it into SQLite or
PostgreSQL, and reports tokens, cost, models, clients, cache usage, code
changes, and Copilot AI credits. Your usage data stays on your machine unless
you explicitly configure a PostgreSQL server.

> **Project status:** early access. Provider adapters and report fields are
> still expanding. Feedback and fixtures are welcome.

## Highlights

- Daily, weekly, monthly, yearly, and arbitrary date-range reports.
- Input, output, reasoning, cache-read, cache-write, and total-token breakdowns.
- Model and client attribution, including CLI, IDE, Desktop, and Copilot usage.
- SQLite by default, with optional PostgreSQL storage.
- Idempotent ingestion, raw-event preservation, and incremental processing.
- Copilot CLI and VS Code Copilot model, token, and AI-credit tracking.
- Telemetry hooks with stdin, positional payload, spool-only, and daemon modes.
- macOS, Linux, and Windows release binaries.

## Installation

Download the archive for your platform from the
[latest GitHub release](https://github.com/binzhango/agentusage/releases/latest),
extract it, and put the `agentusage` binary on your `PATH`.

Example for Apple Silicon macOS:

```bash
curl -fL -o agentusage.tar.gz \
  https://github.com/binzhango/agentusage/releases/latest/download/agentusage-macos-aarch64.tar.gz
tar -xzf agentusage.tar.gz
sudo install -m 0755 agentusage /usr/local/bin/agentusage
agentusage --version
```

Available release targets:

| Platform | Archive |
| --- | --- |
| macOS Apple Silicon | `agentusage-macos-aarch64.tar.gz` |
| Linux ARM64 | `agentusage-linux-aarch64.tar.gz` |
| Linux x86_64 | `agentusage-linux-x86_64.tar.gz` |
| Windows x86_64 | `agentusage-windows-x86_64.zip` |

Release archives include `SHA256SUMS`. Verify the checksum before installing
in a production environment.

## Quick start

```bash
agentusage daily
```

On first use, the CLI checks for an initialized database. If none exists, it
asks whether to initialize SQLite, use PostgreSQL, or continue with the JSONL
fallback. Non-interactive invocations do not silently initialize a database.

## Reports

All report commands accept `--provider`.

```bash
# Today
agentusage daily --provider codex
agentusage daily --provider claude_code
agentusage daily --provider opencode
agentusage daily --provider copilot

# Specific date
agentusage daily --provider codex --date 2026-07-19

# Week, month, and year
agentusage weekly --provider codex
agentusage monthly --provider copilot --month 2026-07
agentusage yearly --provider claude_code --year 2026

# Inclusive date range
agentusage range --provider copilot \
  --from 2026-07-01 --to 2026-07-19
```

Reports include:

- requests, prompts, sessions, lines added, and lines removed;
- input, output, reasoning, cache-read, cache-write, and total tokens;
- estimated cost and cache-hit rate when pricing data is available;
- model and client breakdowns;
- Copilot AI credits and native AI-unit values when the source provides them.

Codex can read an alternate rollout-log directory:

```bash
agentusage daily --provider codex --sessions-dir /path/to/codex/sessions
```

## Supported providers

| Provider | Local source | Report details |
| --- | --- | --- |
| `codex` | Codex rollout JSONL | Tokens, models, cache, cost, sessions, and code changes |
| `claude_code` | Claude Code session JSONL | Tokens, models, sessions, and desktop quota signals |
| `opencode` | OpenCode session JSONL | Tokens, models, sessions, and cost fields |
| `copilot` | Copilot CLI databases and VS Code chat JSONL/logs | CLI/IDE attribution, tokens, models, and AI credits |

For VS Code Copilot, an entry such as `MAI-Code-1-Flash • 1.6 credits` is
reported with its resolved model and exact `copilotCredits` value when that
metadata is present locally.

## Storage and configuration

Provider reports use separate SQLite databases by default:

```text
~/.local/state/agentusage/codex.db
~/.local/state/agentusage/claude_code.db
~/.local/state/agentusage/opencode.db
~/.local/state/agentusage/copilot.db
```

Telemetry hooks and the daemon use:

```text
~/.local/state/agentusage/telemetry.db
```

Set `XDG_STATE_HOME` to change the state directory:

```bash
XDG_STATE_HOME="$HOME/.local/state" agentusage daily --provider codex
```

PostgreSQL is available through `AGENTUSAGE_POSTGRES_URL`. When no initialized
provider SQLite database exists, the first-run prompt can select PostgreSQL:

```bash
export AGENTUSAGE_POSTGRES_URL='postgresql://user:password@localhost/agentusage'
agentusage monthly --provider copilot
```

The project does not use an `OPENUSAGE_*` database variable.

## Telemetry hooks and daemon

Pass a hook payload positionally:

```bash
agentusage telemetry hook codex \
  '{"turn_id":"turn-1","usage":{"input_tokens":10,"output_tokens":4}}' \
  --verbose
```

Or pipe the payload through stdin:

```bash
printf '%s' '{"event":"message","usage":{"input_tokens":10}}' \
  | agentusage telemetry hook claude_code --verbose
```

Supported hook sources are `codex`, `claude_code`, and `opencode`. Useful
options include:

- `--account-id` to preserve an account dimension;
- `--db-path` to use a custom telemetry database;
- `--spool-only` to write to the local spool without immediate ingestion;
- `--verbose` to print the event and deduplication result.

Start the daemon with the default or a custom database:

```bash
agentusage telemetry daemon
agentusage telemetry daemon --db-path /path/to/telemetry.db
```

## Command reference

agentusage daily --help
agentusage weekly --help
agentusage monthly --help
agentusage yearly --help
agentusage range --help
agentusage telemetry --help
```

## Privacy and data safety

`agentusage` is designed to operate locally. It reads provider files and
stores normalized events in local databases; it does not require a hosted
account or send usage data to a project-controlled service. Treat local usage
databases, raw events, and PostgreSQL credentials as sensitive data.

## Development

Contributor checks are documented in
[docs/DEVELOPMENT.md](docs/DEVELOPMENT.md). Automatic versioning, crates.io
publishing, platform builds, and GitHub releases are documented in
[docs/RELEASING.md](docs/RELEASING.md).

Release history is maintained in [CHANGELOG.md](CHANGELOG.md).

The Rust source is rooted in this repository. The local reference checkout is
excluded from Rust packages, GitHub Actions, and release archives.

## Contributing

Bug reports and pull requests are welcome. When adding or changing a provider:

1. Include a sanitized fixture or regression test when possible.
2. Preserve idempotent ingestion and backward-compatible storage behavior.
3. Run the checks in [docs/DEVELOPMENT.md](docs/DEVELOPMENT.md).
4. Do not commit provider credentials, raw private transcripts, or local
   databases.
