Logan Johnson a38fedb234 fix(desktop): recognize agents without NIP-OA in Huddles (#8544)
🤖
## Summary
In a Huddle (a voice call in a channel), Buzz Desktop decides which
participants are agents. It uses that answer to choose whose text it
speaks aloud, which agents can publish voice, and when the last person
leaves and the Huddle ends.

Desktop currently treats a participant as an agent only when its channel
role is `bot`. #8494 changes the relay so that it gives `bot` only to
agents with a verified owner attestation (NIP-OA). After that change,
agents without an attestation join as ordinary members, and Desktop
treats them as people:
- their messages are not spoken,
- their voice publisher is refused,
- the Huddle stays open after the last person leaves while such an agent
is still connected.

With this PR, Desktop also counts a member as an agent when a trusted
person has published a managed-agent record for it. Desktop already
publishes such a record for every agent it runs, on every machine.
Trusted people are:
- **you**, so your own agents count as agents on all of your machines;
- **the Huddle's owner**, usually the person who started it, so the
agents they added count as agents for everyone who joins.

Some agents without an attestation still count as people: an agent added
by someone who does not own the Huddle, as seen from any machine other
than that person's. The only way to recognize those agents is an owner
attestation. This PR does not sign one.

### Details
- `huddle/roster.rs` (`fetch_huddle_roster`) is now the only place that
decides agent or person for Huddles. A member is an agent if its role is
`bot`, or if the current user or a channel `owner` published a
kind:30177 managed-agent record whose `d` tag is that member's key.
Records from other authors are ignored. Records whose signature does not
verify are ignored.
- All Huddle checks use the roster: voice-publisher authorization,
`get_huddle_agent_pubkeys` (spoken-text gating and the participant
list), the periodic roster refresh, adding an agent, cleanup at the end
of the Huddle, and the last-person check.
- Trusting the owner's records is a compatibility policy for Huddles,
not proof of identity. A record creates no owner. It lets the channel
owner mark a member as an agent for every Huddle behavior that reads the
roster: spoken text, voice publishing, remote transcription and
turn-taking (both skip agent audio), cleanup, and the last-person check.
Before #8494 the client chose the role, so an owner could already do
this by labeling a member `bot`.
- If the managed-agent records cannot be read, Desktop does not drop
agents that have the `bot` role. Spoken text, voice publishing, adding
agents and cleanup keep working for those agents. The Huddle does not
end automatically, because an agent without an attestation could be
counted as a person. When you join, and on each periodic refresh,
Desktop adds the `bot` agents to its stored list and keeps stored agents
that are still members.

### Related issue
Follow-up to #8494 (the relay stores `bot` only for attested agents). No
existing issue found.

### Testing
- New helper-level unit tests in `huddle/roster.rs`. They do not run the
relay query, the pipeline writers or the leave path.
- the `bot` role, the user's own record and the owner's record each mark
a member as an agent;
  - records from other members are ignored;
  - a record with a forged signature is ignored;
- when the record read fails, `bot` agents stay agents, the Huddle
cannot end automatically, and the next successful read restores the full
roster.
- when the record read fails, a joiner with no stored agents still
stores the `bot` agents, an agent known only by its record stays stored,
and a stored agent that left drops out.
- New tests in `huddle/roster_hydration_tests.rs` run the real
`post_connect_setup` and hot-start entrypoints against a fake relay
whose managed-agent record read fails. The voice-model, audio and
pipeline steps are passed in, so the tests replace them. Post-connect
stores the `bot` agent before media setup starts; the hot-start refresh
also keeps a still-member agent known from an earlier record and drops
one that left; the same incomplete roster gives no human count for the
last-person check. The tests fail when either entrypoint skips its
roster read, and when the roster code accepts only complete rosters.
- `cargo test --lib huddle::` (Huddle tests only), `cargo clippy --tests
-D warnings` and `cargo fmt --check` pass in `desktop/src-tauri`.
- Not yet tested in a live Huddle.

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.
