The relay side of NIP-FI agent tokens. An agent token has its own type, `nip-fi-agent+jwt`, and carries its human owner's pubkey in `nostr_owner_pubkey`. This PR verifies that claim, makes denying or disconnecting the owner cut off every agent that owner authorized, and makes the verified owner decide community admission. A relay without agent support refuses the unknown type, so nothing needs to advertise or configure agent support. The `NIP-FI.md` text for the agent type is included. Builds on #8372 and #8377 (both merged). ### Owner claim and owner deny - **Token type binds the owner claim (`buzz-auth`).** A `DedicatedNipFi` issuer policy accepts `nip-fi+jwt` (human) and `nip-fi-agent+jwt` (agent); `AccessTokenAtJwt` policies stay `at+jwt`-only with their `client_id` and subject rules unchanged, and unknown types are refused. An agent token must carry a lowercase-hex `nostr_owner_pubkey` distinct from its `nostr_pubkey`; a human or `at+jwt` token carrying the claim with any value, including null, is `evidence_rejected`. The verified owner is exposed as `VerifiedAssertion::owner()`. - **No agent switch.** There is no relay setting, NIP-11 field or operator binding field for agent support. - **Session owner.** Each connection records its NIP-FI issuer and the agent's owner (`NipFiSession`) on the root WebSocket manager and the audio registry. `disconnect_nip_fi(iss, target)` closes a connection when either its own key or its recorded owner equals the target. - **Owner deny check.** `nip_fi_core::assertion_denied` checks the deny set for both `(iss, k)` and `(iss, owner)`, and every existing deny check uses it: WebSocket before upgrade and after registration, HTTP, audio, and the shadow observer, so shadow and enforce make the same decisions. The shadow disconnect observer matches a session's key or owner under its issuer with the same rule, so an owner's disconnect records a would-close for its agents. ### Shadow owner check In shadow mode, WebSocket AUTH, audio join and HTTP admission record a `Stage::Owner` verdict when an admitted agent token's owner is banned (`owner/denied`), conflicts with the agent's stored owner (`owner/denied`), or cannot be checked because a read failed (`owner/unavailable`). These are reads only; shadow admission is unchanged. Shadow applies the same stored-owner rule as enforce but never writes the link, so it can't predict a later owner-link write failure, or which of two racing first links wins. ### Admission through the verified owner - **Owner bans, unconditionally.** `community_ban_outcome` takes the token owner and checks its ban in place of a NIP-OA owner. That applies whether the agent is a member itself, the relay is open, or the agent is admitted through its owner. - **Owner-derived membership.** In `api::relay_members::check_membership`, an agent that is a member itself is still admitted first. Otherwise, when a verified assertion names an owner, the owner's membership decides (`MembershipDecision::ViaOwner`), and no NIP-OA is needed on the connection. The issuer has already passed this community's NIP-FI binding check at that point. When a token owner is present it is the only owner considered. - **Stored-owner consistency.** `link_agent_owner` replaces the boolean `materialize_nip_oa_owner` result with `OwnerLink::{Linked, Conflict, Unavailable}`. An unset stored owner is recorded, so relay bans and roster removal of the owner reach the agent through `revoke_live_access`. Shadow and enforce judge the stored owner through one read, `stored_owner_link`, and `link_agent_owner` writes (atomically, first write wins) only when that read finds no owner; a failed read fails closed. If the stored owner differs from the token owner, the request is refused with `authorization denied` on HTTP, WS and audio. A NIP-OA owner conflict keeps its existing link-error refusal. - **One decision on every surface.** Root WS AUTH, audio registration and every NIP-98 HTTP route (bridge, `buzz/v1`, git transport and settings, invites, media, workflows, moderation reads) pass `NipFiAdmission::token_owner()` / `VerifiedAssertion::owner()` into the same ban, membership and owner-link steps. The final socket check rereads bans and writer-side membership; it doesn't reread the owner link, which is written once from NULL. HTTP membership still goes through the bounded replica read. With a verified agent token, every HTTP admission refusal, including the fresh ban rereads in `buzz/v1` and Git settings, is NIP-FI's fixed `authorization_denied` (or `authorization_unavailable` when a dependency fails), and audio checks bans before writing the owner link. `enforce_relay_membership` now takes the `TenantContext`, because it writes the owner link. - **Publishing.** A ban caught while publishing over `POST /events` after the shared membership check is also an admission refusal. Ingest reports it as a typed `IngestError::Ban` (banned, or ban lookup unavailable) at the write gate, the HTTP typing indicator's cached gate, and the moderation and relay-admin command rereads. `IngestError::Ban` carries the legacy error. The bridge turns it into the fixed `authorization denied` / `authorization unavailable` only when the request carries a verified agent token. WebSocket and token-less HTTP responses are byte-for-byte unchanged, and timeouts, scopes, permissions and every other ingest error keep their existing responses. ### Rollout - **Deploy the relay before kgoose.** An older relay refuses `nip-fi-agent+jwt`, so agents are locked out until both are deployed. Humans are unaffected. - **There is no agent-only switch.** Setting NIP-FI to shadow or off turns it off for humans too. - **Rollback is safe for owner links.** Stored owner links survive a rollback, and the older code still honors them. - **Shadow signals:** in `buzz_nip_fi_shadow_total`, `stage="owner"` means an owner would-deny (`owner/denied`) or an owner read that was unavailable (`owner/unavailable`), not a success. A clean agent admission shows as `stage="admit", outcome="admit"`. - **The relay checks that the owner is a member, not which issuer the owner logged in through.** In a community that trusts several issuers, any trusted issuer can name any member as owner. That matches the spec: the issuer is trusted to vouch for the owner, and kgoose requires the owner's attestation. Agent tokens are only issued to relays whose NIP-FI binding trusts the issuer, and NIP-FI itself is off unless configured. No deployed config or secrets change. --------- Signed-off-by: Will Pfleger <pfleger.will@gmail.com> Signed-off-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz> Co-authored-by: Hayt <211b96e6a2b7f45fd4047988976c7bbbeeda0c15f3ae7b32eec20834b5a55118@buzz.block.builderlab.xyz> Co-authored-by: Duncan <dcfd242e557282d7a1e2cf2e6877522682f1e5c6156dc92ca7d90eaedd3b0f95@buzz.block.builderlab.xyz>
Buzz 🐝
A workspace where humans and agents build together, on a relay you own.

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:
| 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:
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)

Community
- Buzz feedback community — ask questions, share feedback, and connect with other Buzz users

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.
