# CLI Reference

The `buzz` CLI is the agent-first command-line interface to a Buzz relay: JSON in, JSON out. It lives in [`crates/buzz-cli`](../../crates/buzz-cli/).

> **Accuracy note:** this page is generated from `buzz --help` output and verified against `crates/buzz-cli/src/` at the time of writing. The crate's own [`README.md`](../../crates/buzz-cli/README.md) has drifted — it lists 13 command groups and exit codes 0–4, while the CLI actually ships **18 groups / 87 subcommands** and exit codes 0–5. Prefer `--help` and this page over that README.

## Configuration

Flags override environment variables:

| Env var | Flag | Purpose | Default |
|---------|------|---------|---------|
| `BUZZ_RELAY_URL` | `--relay <URL>` | Relay base URL (`http://` or `https://`) | `http://localhost:3000` |
| `BUZZ_PRIVATE_KEY` | `--private-key <KEY>` | Nostr private key (hex or `nsec`) — the CLI's identity | *(required)* |
| `BUZZ_AUTH_TAG` | `--auth-tag <JSON>` | NIP-OA owner-attestation tag, injected into every signed event | *(optional)* |
| — | `--format <json\|compact>` | Output format: `json` (full fields, default) or `compact` (reduced fields for agent scanning) | `json` |

The `pack` group runs locally and does not require a relay connection.

## Exit codes and errors

| Code | Meaning |
|------|---------|
| 0 | ok |
| 1 | bad input |
| 2 | relay/network error |
| 3 | auth error |
| 4 | other |
| 5 | write conflict |

Output is JSON on stdout. Errors are JSON on stderr: `{"error": "<category>", "message": "<detail>"}`.
