Team catalog projections (`kind:30178`) embed every member's system
prompt, so they need the same read gate personas already have: only the
author sees an unshared event. The gate was hardcoded to `kind:30175` at
six read surfaces plus the SQL pushdown, so rather than adding a second
special case it becomes kind-generic over `SHARED_GATED_KINDS = {30175,
30178}`.
## Kind 30178
New parameterized-replaceable kind, addressed by `(pubkey_o, 30178,
team_id)`. It embeds sanitized member projections instead of referencing
`kind:30175` heads — a foreign reader of a shared team could not
otherwise hydrate members whose own persona events are unshared or, for
built-ins, absent entirely. `kind:30176`'s wire body is untouched, so
device sync keeps its contract.
## Kind-generic shared gate
`buzz_core::kind` replaces `is_persona_shared_kind` /
`is_unshared_persona_event` / `persona_event_is_shared` with
`SHARED_GATED_KINDS` and the kind-agnostic `is_shared_gated_kind` /
`is_unshared_gated_event` / `event_is_shared`. Every read surface
consults the set:
| Surface | File |
|---|---|
| REQ historical delivery + `ids` lookup |
`crates/buzz-relay/src/handlers/req.rs` |
| Live fan-out | `crates/buzz-relay/src/handlers/event.rs` |
| COUNT fallback | `crates/buzz-relay/src/handlers/count.rs` |
| NIP-98 HTTP `/query`, `/count`, `/search` |
`crates/buzz-relay/src/api/bridge.rs` |
| Pre-`LIMIT` SQL pushdown | `crates/buzz-db/src/event.rs` |
The SQL clause generalizes from `kind != 30175` to `kind NOT IN (...)`
bound from `SHARED_GATED_KINDS`, still applied before `ORDER BY … LIMIT`
so a page of newer private events cannot starve an older shared one off
the candidate set. `EventQuery::persona_reader` is renamed
`shared_gated_reader` and `needs_persona_filtering` to
`needs_shared_gate_filtering` to match.
Because the `buzz-core` rename has consumers outside the relay, the four
desktop call sites of `persona_event_is_shared` travel with it:
`desktop/src-tauri/src/commands/personas/pending.rs`,
`desktop/src-tauri/src/event_sync.rs`, and two in
`desktop/src-tauri/src/managed_agents/persona_events.rs`. Each call is
unchanged apart from the name — the persona `shared` projection behaves
exactly as before.
## Ingest validation
`validate_persona_envelope` splits into two reusable pieces —
`validate_shared_tag` (exactly-two-element `["shared","true"]`, at most
one occurrence) and `single_bounded_d_tag` (exactly one `d` tag,
non-empty, `<=64` chars, no ASCII control characters or whitespace).
`validate_team_catalog_envelope` composes both; personas additionally
keep the slug grammar `^[a-z0-9][a-z0-9_-]{0,63}$`.
`kind:30178` deliberately does **not** get the slug grammar. Team ids
are UUIDs or built-in identifiers such as `builtin-team:welcome`, and
the colon is not slug-legal; rewriting ids to fit would break NIP-33
addressing against the team's own `kind:30176` head. The non-empty and
exactly-one checks are load-bearing regardless — without them generic
NIP-33 storage maps a missing `d` onto `(pubkey_o, 30178, "")` and every
team overwrites its predecessor.
The exact two-element `shared` shape is enforced because the SQL
visibility clause is JSONB containment (`tags @>
'[["shared","true"]]'`), which would match a three-element superset such
as `["shared","true","extra"]`.
`kind:30178` is also added to the `Scope::UsersWrite` allowlist and to
`is_global_only_kind`, so a stray `h` tag cannot channel-scope an
owner-authored definition.
## Deferred
`kind:30176` is deliberately not a gate member. Its writers never emit
`shared`, so catalog opt-in semantics do not describe it — it needs
owner-private reads driven by an authenticated principal set, tracked as
a separate follow-up.
## Tests
- 19 new `ingest.rs` unit tests covering the 30178 envelope (UUID and
colon `d` tags, 64-char boundary, non-ASCII bound,
empty/valueless/duplicate/missing `d`, embedded newline, `shared`
false/three-element/duplicate, scope and global-only membership).
- Persona regressions for the valueless `["d"]` shapes, since the
`d`-tag helper is shared by both validators.
- Existing `kind.rs` gate tests generalized and extended to assert the
gate applies to 30178 as it does to 30175.
- New `crates/buzz-test-client/tests/e2e_team_catalog.rs`: 9 WS-level
tests over a live relay covering author reads of unshared heads, foreign
omission from REQ, `ids`-lookup denial, COUNT existence-leak, share and
unshare transitions, and the mixed-kind filter case.
- `.github/workflows/ci.yml` adds `--test e2e_team_catalog` to the Relay
E2E job so the new suite runs.
## Docs
`docs/nips/NIP-AP.md` gains a "Team catalog projection: kind:30178"
section and an "Ingest validation: kind:30178" subsection, records the
gate as kind-generic, documents 30178 deletion vs. unshare semantics,
and adds a security note that sharing a team exposes every member's
instructions even when that member's own `kind:30175` head is unshared.

Buzz 🐝
A workspace where humans and agents build together, on a relay you own.
Vision · Sovereign · Forge · Agents · Architecture · Apache 2.0
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.
A look inside
 Agents are members, not bots. Add an agent to a channel the same way you add a person. |
 Spin up a room in seconds. Name it, describe it, make it private. |
 Media you can talk about. Leave comments pinned to specific frames. |
|
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 — macOS (.dmg), Linux (.AppImage / .deb), or Windows (.exe). Install it like any other app.
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 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)

just test # Full suite (starts services if needed)
just ci # Everything CI runs
just reset # ⚠️ Wipe data + recreate
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.
