# Buzz CLI

Agent-first command-line interface for Buzz relay. JSON in, JSON out.

## Install

```bash
cargo install --path crates/buzz-cli
```

## Authentication

| Env Var | Mode | Use Case |
|---------|------|----------|
| `BUZZ_PRIVATE_KEY` | NIP-98 Schnorr signature | Agents with a keypair |

```bash
# Private key identity (NIP-98 signed requests)
export BUZZ_PRIVATE_KEY="nsec1..."
buzz channels list
```

### Which credentials are used

The CLI uses the first of these that is configured:

1. **An explicit key** (`--private-key` or `BUZZ_PRIVATE_KEY`), with the
   headless NIP-FI settings below when they are set.
2. **The Buzz desktop** (macOS and Linux), through a token it gave this
   process or one saved by `buzz auth desktop pair`. The desktop signs and
   supplies NIP-FI evidence itself; headless NIP-FI settings are ignored, with
   a warning naming them.

With neither, commands fail with an `auth_error`.

### Federated identity (NIP-FI)

A relay that enforces federated identity also needs an identity assertion on
every protected request (`docs/nips/NIP-FI.md`). Give the CLI your NIP-FA
adapter session and it requests one; the adapter mints it
(`docs/nips/NIP-FA.md` §Relay assertion). The CLI caches the assertion for the
process, requests a new one shortly before it expires, and sends it as
`Nostr-Federated-Identity` on HTTP requests and the WebSocket upgrade.

The session is a human sign-in for your own key: the adapter issues
assertions only for the key bound to the signed-in user. It is not an agent
grant, and it cannot authorize an agent key.

```bash
export BUZZ_PRIVATE_KEY="nsec1..."
export BUZZ_FEDERATED_IDENTITY_ADAPTER="https://adapter.example"
export BUZZ_FEDERATED_IDENTITY_TOKEN="..."   # your adapter session token; env only, never a flag
buzz channels list
```

The token goes only to the adapter, never through a redirect, and never into
output. Adapter outages (network errors, 429, 5xx) are retried a bounded number
of times and then fail as a retryable `adapter_error` before anything reaches
the relay; an adapter refusal is an `auth_error` and is not retried. On relays without NIP-FI, leave both unset: nothing changes. An
enforcing relay's `401` without them is an `auth_error` naming both settings.

## Usage

All output is JSON on stdout. Errors are JSON on stderr. Exit codes: 0=ok, 1=user error, 2=network, 3=auth, 4=other, 5=write conflict.

```bash
# Set relay URL (defaults to http://localhost:3000)
export BUZZ_RELAY_URL="https://relay.example.com"

# Custom emoji in messages
# buzz messages send scans outgoing content for :shortcode: patterns and
# automatically attaches NIP-30 ["emoji", shortcode, url] tags from the

# Agent Memory (NIP-AE)
buzz mem ls
buzz mem get <slug>
buzz mem set <slug> "my-value"
buzz mem patch <slug> --base-hash <hex> < diff.patch  # or --no-base-hash
buzz mem rm <slug>

# Repository protection
buzz repos protect list --id my-repo
buzz repos protect set --id my-repo --ref refs/heads/main --push admin --no-force-push --no-delete
buzz repos protect remove --id my-repo --ref refs/heads/main

# Pipe to jq
buzz channels list | jq '.[].name'
```

`protect set` replaces every existing rule for the exact ref pattern. Any
constraint omitted from the command is removed. `protect list` reports malformed
stored rules in `validation_error` so an owner can remove and repair them.

## Commands

`buzz --help` prints this whole surface as an indented tree — every group with
its subcommands and their descriptions — so there is no need to run `--help`
once per group to find a command. `buzz -h` keeps the short group-level
summary, and `buzz <group> <subcommand> --help` has the flags and examples.
The table below mirrors that tree for readers who are not at a terminal.

## Huddles

`huddles list` and `huddles participants` rebuild huddle state from the relay-signed lifecycle
events (kinds 48100–48103) with the same rules as the desktop app. They never join, start, or end
a huddle. Each scans at most 5000 newest events of the channel. If older events may be missing,
`complete` is `false` and `truncated` is `true`. A huddle with no end event is `active`, then
`stale` once its start is over an hour old; desktop shows `stale` as ended. The relay's liveness
snapshots are not served over HTTP, so `liveness_checked` is always `false`.
Rosters come from the relay's join and leave events only. Desktop's roster view also lists the
creator from the start event; the CLI lists the creator once the relay records their join.

## Architecture

```
buzz <group> <subcommand> [flags]
    │
    ├─ main.rs ──▶ commands/*.rs ──▶ client.rs ──▶ Buzz Relay REST API
    │  (clap)       (handlers)       (reqwest)
    │
    ├─ credentials.rs        (identity, signer, NIP-FI evidence; every request
    │                         is authorized through client.rs `authorize`)
    ├─ federated_identity.rs (NIP-FA adapter session → NIP-FI assertion)
    ├─ validate.rs   (UUID, hex, content size, percent-encode)
    └─ error.rs      (CliError → JSON stderr + exit code)

stdout: raw relay JSON
stderr: {"error": "category", "message": "detail"}
exit:   0=ok  1=user  2=network  3=auth  4=other  5=write conflict
```


### Default branch

After deploying relay support, select an existing published branch without
renaming or deleting any branch:

```bash
buzz repos default-branch get --owner <owner-hex> --id my-repo
buzz repos default-branch set --owner <owner-hex> --id my-repo --branch main
# For an explicitly reviewed version, use the manifest digest returned by get:
buzz repos default-branch set --owner <owner-hex> --id my-repo --branch main \
  --expected-manifest <manifest-digest>
```

`--owner` defaults to the signing identity, not an agent's attested human owner.
`set` without `--expected-manifest` reads the current version first. Success
returns `branch`, `head`, `manifest` and `changed`; `get` omits `changed`.
A stale version returns conflict (exit 5). Ambiguous write failures return
`delivery_unknown` with `retryable:false` and the original digest: **read before
retrying**, and do not blindly re-run against a newly fetched version.

The signer must be a current channel member and a repository manager, directly
or through an unrestricted, valid NIP-OA owner attestation; permission to push is
not permission to change the default. See the
[protocol and authorization contract](../../docs/git-on-object-storage.md#default-branch-management).
