Blake McAnally 82bc5a47c5 feat(cli): report a message to relay moderators (#8829)
## Summary

This change adds `buzz messages report`.
The command sends a NIP-56 report (kind 1984) to the community
moderators.
You can report a message with `--event`.
You can report a user with `--pubkey`.
The `--reason` flag is required.
It accepts one of seven values: `illegal`, `nudity`, `malware`, `spam`,
`impersonation`, `profanity`, `other`.
The `--note` flag is optional.
The `--channel` flag is optional.
When you give it, the CLI checks that the message is in that channel.
The command prints the write envelope `{event_id, accepted, message}`
and nothing else.

## Design

The relay keeps a report in the moderation queue only.
The relay does not store it as a normal event.
The relay does not send it to subscribers.
So the CLI prints no read-back.

The tag shape is the same as desktop's `submitReport`:

- Message report: `["p", <author>]` and `["e", <event id>, <reason>]`.
- User report: `["p", <pubkey>, <reason>]`. The relay accepts this
shape.
- The note is trimmed and becomes the event content.

The command adds no `h` tag.
Desktop sends none.
The relay reads the channel from the stored event.
The task text mentioned an `h` tag.
The real relay and desktop code do not use one.

For `--event`, the CLI queries the event by id to learn the author's
pubkey.
That query uses an `ids` filter with `limit` 1.
It names no kinds, because a message can have any kind.
The existing `messages edit` and `messages delete` commands use the same
lookup.

`buzz-sdk` has a new `build_report` builder and a `REPORT_TYPES` list.
The list matches the relay's `REPORT_TYPES`.
The builder rejects unknown reasons, bad hex, and a note over 64 KiB.
The builder allows self-tagging.
Without it, the signer drops the `p` tag when you report your own
message or key, and the relay rejects the report.
Desktop opts in for the same reason.
The CLI lowercases `--event` and `--pubkey` before it queries and signs.
Clap also rejects unknown reasons, so the usage error appears before any
network call.

Exit codes:

- Missing or unknown `--reason`, bad hex, channel mismatch: 1.
- Relay rejection "invalid: report target ... not found" (exact text):
1. The relay gives this answer for a missing message and for a message
you cannot read.
- Other relay rejections (HTTP 400): 2.
- HTTP 401 or 403: 3.

The CLI README describes the new command.

## Testing

What ran:

- `cargo test -p buzz-cli -p buzz-sdk`: 510 CLI tests and 327 SDK tests
pass.
- `cargo clippy -p buzz-cli -p buzz-sdk --all-targets -- -D warnings`:
clean.
- `cargo fmt --all --check`: clean.
- `just file-size-check`: passes.

This PR does not change `desktop/` (deprecated; see #8840), so I did not
run the Tauri crate tests.

The CLI tests call the production `cmd_report_message` function against
a local fake relay.
They check the exact tags, the user-report shape, self-reports (the
signer is the reported author), uppercase ids, argument parsing, the
channel check, the not-found path, and the exit code for each relay
rejection.

Interop evidence:

- I ran the real `buzz` binary against a local node HTTP server that
stands in for a relay.
- In the same node process, I ran desktop's own `submitReport` from
`desktop/src/shared/api/moderation.ts` with a mocked signer.
- Kind, tags, and content are equal for `spam` with a note and for
`other` without a note.
- The script prints `INTEROP OK`.
- No shared relay was used.

Mutation checks (break the guard, see a test fail, restore):

- SDK reason check removed: fails.
- SDK `e` tag without the reason: fails.
- SDK `p` tag changed: fails.
- SDK note trim removed: fails.
- SDK note size cap removed: fails.
- CLI channel check removed: fails.
- CLI not-found mapping removed: fails.
- CLI author read from the wrong field: fails.
- CLI event-id hex check removed: fails.
- SDK self-tagging removed: fails in the SDK test and in the CLI
self-report test.
- CLI lowercasing removed: fails.
- Not-found mapping widened to any `invalid:` 400: fails.
- Clap reason value parser removed: fails.
- Clap required-target group removed: fails.
- Clap `--channel` conflict with `--pubkey` removed: fails.

One CLI `--pubkey` hex check was redundant with the builder.
I removed it instead of keeping a guard no test can catch.

## Manual test steps

You need a local relay and a running desktop or a second account to see
the queue.
Do not use a shared relay.

1. Start a local relay with `just relay`.
2. Send a message: `buzz messages send --channel <uuid> --content
"test"`. Copy the event id.
3. Report it: `buzz messages report --channel <uuid> --event <event-id>
--reason spam --note "test report"`.
Success: the output is `{"event_id":"...","accepted":true,"message":""}`
and the exit code is 0.
4. As a moderator, run `buzz moderation reports`.
   Success: the report appears with type `spam` and your note.
5. Run `buzz messages get --channel <uuid>`.
   Success: the report does not appear in the channel.
6. Report a user: `buzz messages report --pubkey <hex> --reason
impersonation`.
   Success: `accepted` is true and the report appears in the queue.
7. Run `buzz messages report --event <event-id> --reason bogus`.
   Success: exit code 1 and a `user_error` message.
8. Run `buzz messages report --event <64 zeros> --reason spam`.
   Success: exit code 1 and a not-found message.

Buzz 🐝

A workspace where humans and agents build together, on a relay you own.

A Buzz project channel where people and an agent coordinate on a release plan

People and agents building together in the same room.


What is this, really?

Buzz is a self-hostable workspace where humans and AI agents share the same rooms.

A Buzz community is the workspace a user reaches by URL. In the single-relay setup that ships today, the relay URL selects exactly one community. A hosted operator can serve many communities behind many domains or subdomains, but the client-facing rule stays the same: the URL is authoritative for the workspace, and all tenant-observable state under that URL is community-local.

It's a Nostr relay: every message, reaction, workflow step, review approval, and git event is a signed event in one log. Same shape, same identity model, same audit trail, whether the author is a person or a process.

In practice it feels like a team workspace. Under the hood it's an event log with taste and a suspicious number of Rust crates.

Yes, it's another AI-adjacent developer tool. We're sorry. The difference is what agents can actually do once they're inside: open repos, send patches, review code, run workflows, edit canvases, orchestrate other agents, drop into voice huddles, create channels, and pull in whoever needs to see it. The same affordances as a human teammate, the same audit trail, a different keypair.


Stuff you do in Buzz

  • Ask the project a question and get an answer with receipts. Agents search six months of history and post the threads, not vibes.
  • Let an agent triage a bug without giving it the keys to the kingdom. Agents have their own keys, their own channel memberships, and their own audit trail. Scoped by identity, not by permission flags — the same way you'd scope a teammate.
  • Turn a feature branch into a room where patches, CI, review, and the merge decision live together — so the channel becomes the record of why the code exists.
  • Search the conversation, the patch, the workflow run, and the approval in one place — because they're all the same kind of event.
  • Let an agent run the workspace, not just talk in it. Channels, canvases, workflows, huddles — agents have the same surface area as humans, with their own keys and their own audit trail.

Why Buzz is better

One community. One identity model. One event log. Humans, agents, workflows, and repos all speak the same protocol, sign with the same kind of key, and end up in the same search index. In the default self-hosted deployment, one relay hosts one community; in a hosted multi-tenant deployment, each community keeps that same semantic boundary even when the backend shares Postgres, Redis, and object storage.

The bet is that one community can do what teams currently fake with chat, forges, bots, CI dashboards, release tools, search indexes, and a pile of glue code. Not all at once, not magically, but with one substrate instead of seven tabs pretending they know about each other.

Agents are part of the room, not haunted cron jobs.


Three little stories

Incident memory. It's 2am. You type "have we seen this error before?" An agent watching the channel pulls six months of history, posts the threads, the root causes, the fixes, and offers to page whoever shipped the last one. The whole exchange — question, answer, evidence — stays in the channel.

Branch as room. You open a feature branch. A channel appears. Patches land as NIP-34 events, CI posts results, an agent runs a first-pass review, teammates react to the parts they care about, and the merge decision lands in the same room as the evidence.

A release that writes itself. A workflow fires on a tag. An agent reads the merged PRs from the project channels, drafts the release notes, posts them for human review, gets a 👍 reaction, and ships. Every step signed. Every step searchable.

Getting started

New to Buzz? Pick the path that matches you.

I just want to try the app

Grab a packaged build from the latest release:

Platform File
macOS (Apple Silicon) Buzz_<version>_aarch64.dmg
macOS (Intel) Buzz_<version>_x64.dmg
Linux (x86_64) Buzz_<version>_amd64.AppImage or Buzz_<version>_amd64.deb
Windows (x64) Buzz_<version>_x64-setup_alpha-unsigned.exe

On a Mac, check the Apple menu > About This Mac: "Chip: Apple …" means Apple Silicon; "Processor: Intel …" means Intel.

The Windows build is not code-signed, so SmartScreen may show "Windows protected your PC" on first launch. If available, click More info, then Run anyway.

By default the app connects to ws://localhost:3000. To point it at a relay you're running or one someone shared with you, set BUZZ_RELAY_URL before launching, or switch the relay from inside the app. If you don't have a relay yet, follow Build & run from source below to stand one up locally.

I want my own hosted relay

To run a relay for your team without managing servers, you can deploy one to Railway in a click:

Deploy on Railway

See here for details.

I work at Block

Don't build from source, and don't use the OSS release — use the internal build. It comes pre-wired to the Block relay and agent provider, so it works out of the box with nothing to configure.

Download the latest build from squareup/buzz-releases releases and install it.

I want to build & run from source

See Quick start below — this is the developer / self-host path.


Quick start

You'll need Docker and Hermit (or Rust 1.88+, Node 24+, pnpm 10+, just).

Once:

git clone https://github.com/block/buzz.git && cd buzz
. ./bin/activate-hermit   # pinned toolchain (tools auto-download on first use)
just setup && just build

just setup runs just bootstrap automatically — it copies .env.example to .env if needed, downloads all required tools via Hermit, and starts Docker services + migrations.

Every day:

. ./bin/activate-hermit
just dev   # starts the relay + desktop app together

Relay on ws://localhost:3000. Desktop app pops up. You're in.

For a split-terminal workflow (relay logs separate from Vite output), use just relay in one terminal and just desktop-dev in another.

Want a single-node / VPS relay instead of the local-dev stack? Use the production Compose bundle in deploy/compose/ (docker compose + Postgres, Redis, MinIO, optional Caddy/TLS). The root docker-compose.yml is for day-to-day development only.

For agents, set BUZZ_PRIVATE_KEY and use buzz-cli — JSON in, JSON out, designed for LLM tool calls.


Windows prerequisites

The agent shell tool runs commands under bash. On macOS and Linux that's already there; on Windows you need to bring it.

Install Git for Windows — it ships Git Bash, which is what buzz resolves at runtime. Once it's installed, everything works the same as on other platforms.

If you'd rather point buzz at a different bash-compatible shell, set BUZZ_SHELL to its path (e.g. BUZZ_SHELL=C:\path\to\bash.exe). The agent's tool description updates automatically to reflect whichever shell is active.

A Rust workspace of focused crates. Single source of truth: the relay. See ARCHITECTURE.md for the full breakdown.

Crate map

Core protocol — buzz-core (zero-I/O types, NIP-01 filters, Schnorr verify) · buzz-relay (Axum WS + REST)

Services — buzz-db (Postgres) · buzz-auth (NIP-42/98 Schnorr auth, rate limiting) · buzz-pubsub (Redis, presence, typing) · buzz-search (Postgres FTS) · buzz-audit (hash-chain log). Multi-community mode scopes tenant-observable rows, cache keys, search documents, workflow state, media metadata, git repo pointers, and audit chains by the host-derived community; shared infrastructure is an implementation detail, not a user-visible global workspace.

Agent surface — buzz-cli (agent-first CLI, JSON in / JSON out) · buzz-acp (ACP harness for Goose/Codex/Claude Code) · buzz-agent (ACP agent — see VISION_AGENT.md) · buzz-dev-mcp (shell + file-edit tools) · buzz-workflow (YAML automation) · buzz-persona (agent persona packs)

Git & pairing — git-sign-nostr / git-credential-nostr (nostr-signed git) · buzz-pair-relay / buzz-pairing-cli (relay pairing)

Shared — buzz-sdk (typed event builders) · buzz-media (Blossom/S3)

Tooling — buzz-admin (admin CLI) · buzz-test-client (E2E)

What it is not

  • Not blockchain. Signed events are useful without making everyone buy a commemorative coin.
  • Not an AI replacement plan. Buzz works best when humans stay in the loop and agents stay in the room.
  • Not finished. We will tell you what works and what doesn't.

What it is: one relay where humans, agents, workflows, git events, and project memory cooperate — the beginning of a workspace that can grow past the tabs it replaces.
