Logan Johnson aa5f3e7bde feat(mobile): show conversation activity by the composer, as buzz-app does (#8765)
## Summary

Stacked on #8754. This brings the rest of buzz-app's conversation
activity to mobile.

buzz-app shows who is active in a conversation in one place, just above
the composer (`src/features/messages/TypingIndicator.tsx`). Mobile had
its own design: a typing bubble at the end of the timeline that turned
into the agent's reply (the "handoff"). This change replaces that design
with buzz-app's indicator in channels, DMs, Me and threads.

What the indicator shows, as in buzz-app:

- **On the right: your agents working here.** Up to four agent avatars,
then "+N". "Your agents" are your agent inventory (kind 30177), as in
#8754. Tapping the avatars opens the "Working now" list.
- **On the left: everyone else typing here.** Typing dots and buzz-app's
text: "Alice is typing", "Alice, Bob are typing", "Alice, Bob and 1
others are typing".
- **"Working now" list.** Each row shows the agent, "Working" and, in a
channel view, where it works: "Channel conversation", or "Thread ·
<first 60 characters of the root>", with "+N more" after two places.
- If the agent works in exactly one thread, the row opens that thread. A
thread whose root is not loaded opens by its ID, as buzz-app's link
does. A button at the end of the row opens the agent's activity.
- Otherwise (in a thread view, in Me, in the channel only, or in several
threads), the row opens the agent's activity. As in buzz-app, work in
the channel does not count as a thread: an agent in the channel and one
thread opens that thread.
  - "Activity" is mobile's existing `AgentActivitySheet`.
  - The list closes when the last agent stops.
- **Scope** (`current-activity.ts`: "Channel views include threads;
thread views do not"):

  | View | Your agents | Everyone else |
  |---|---|---|
  | Channel or DM | Here and in any thread | Here only |
  | Thread | This thread only | This thread only |
  | Me | Anywhere | Anywhere |

- **Me** works like buzz-app's Solo chat: with one agent working,
tapping the avatars opens its activity directly.
- **Spoken status:** buzz-app's live status, for example "Jerry, Morty,
Summer are working. Alice is typing". The button says "Activity: Morty
working" or "Activity: 3 agents working".

Changes you will notice compared with #8754 and main:

- The typing bubble at the end of the timeline and the bubble-to-reply
handoff are removed. #8754's channel typing row goes with them. The root
message's reply row from #8754 stays.
- In DMs, other people's agents typing in a thread no longer show at the
DM level. Only your agents do, as in buzz-app. This reverses part of
#8731.
- With no composer, there is no indicator. This applies when you are not
a member or the channel is archived, as in buzz-app (`ChannelsPage`, and
`ThreadPanel`'s `composerRoot`). Before, mobile showed typing in those
threads.

Less than buzz-app, not in this PR:

- Status is always "Working". buzz-app also uses lifecycle evidence
(local agent state, kind 24200) and tool labels. Mobile uses typing
only, as in #8754.
- No hover preview and no keyboard path (Down arrow) into the list.
- The indicator sits in the composer dock, so it moves the timeline up a
little. In buzz-app it floats over the history.

Code:

- `conversation_activity_state.dart` holds the scope rules, read from
typing and the inventory.
- `conversation_activity.dart` is the indicator.
`working_now_sheet.dart` is the list.
- `channel_detail_page/composer_activity.dart` puts it in the channel
composer dock and opens threads. The thread page puts it above its
composer.
- Removed: `inline_agent_typing.dart`, `agent_reply_handoff.dart`,
`agent_typing_bubble.dart`, `typing_avatar_cluster.dart`,
`typing_motion_preview.dart`, `channel_typing_indicator.dart`, and their
tests.

### Related issue

N/A. Reported in Buzz #buzz-bugs (on iOS you cannot tell whether an
agent is down or typing). Searched issues and PRs for duplicates: none
found.

### Testing

Android emulator, local relay, debug build of `8362d46af`.

**Channel and thread.** Demo User mentions Morty. Morty, Summer and
Jerry (in Demo User's agent inventory) type in the mention's thread.
Rick (not in the inventory) types in the thread and in the channel
itself. In the video:

1. The channel shows three agent avatars on the right and "Rick is
typing" on the left. Rick's thread typing does not show.
2. Tapping the avatars opens "Working now". Each row reads "Working" and
"Thread · …". Tapping Morty's row opens the thread.
3. In the thread, the same three agents show, with "Rick is typing" (his
thread typing). Rows there open activity: tapping Morty's opens his
activity sheet.
4. Back in the channel, Summer, Jerry and Rick stop. Only Morty's avatar
is left. Then Morty replies and the indicator goes away. No typing
bubble shows at any point.

**DM.** A DM with Morty (in the inventory) and Rick (not). Demo User
posts. Both type in its thread, and only Morty's avatar shows. Then Rick
also types in the DM itself, and "Rick is typing" shows. Morty replies,
and his avatar goes away.


https://github.com/user-attachments/assets/3614be5f-3a69-4a1a-9290-d1fad16a5445

The UI tree confirmed each state, for example "Summer, Jerry, Morty are
working. Rick is typing", "Activity: 3 agents working", "Morty is
working" (agents only), and "Morty is working. Rick is typing" (DM).

- Widget tests in `channel_detail_page_test.dart` (Typing indicator
group):
- Scope table: Me, channel and DM, for a person and for your agent.
While the inventory loads, an agent never shows as a person.
- The journey from #8754, extended: the composer status and button, the
list's places, opening the thread, thread-view rows opening activity,
and the list closing when work stops.
- Six agents in several places: four avatars and "+2", "+1 more",
scrolling to the last row, opening a thread that is not loaded, and
opening activity.
- Me opens a lone agent's activity directly. People typing: 1, 2 and 3.
- Each new check was made to fail on purpose by removing the code it
guards.
- `just mobile-check` and the full `just mobile-test` passed on
`3480ad238` (3983 passed, 28 skipped).
- Typing names use the full foreground, so they stay readable in dark
themes (review feedback). A test checks the color.
- Auto and Cerveau reviewed it adversarially against buzz-app
origin/main. Their findings are fixed: the list did not scroll, unloaded
threads did not open, the Me behaviour, the non-member indicator, and a
double-tap pop. Their last pass on `2c45f3ec0` found nothing. The device
run then showed that, with only agents working, the spoken status had no
size and Android dropped it. `8362d46af` fixes this, and their review of
that fix found nothing.
- Not yet tested on iOS or by a human.

Buzz 🐝

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

Vision · Sovereign · Forge · Agents · Architecture · Releasing · Apache 2.0

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.

Please do not plan your compliance program around the 💭 column yet. The VISION docs are the long version of what we think this becomes.


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.
