Glossary
Buzz's own documentation mixes vocabularies: the same thing is called a channel and a group, community and relay are used interchangeably, and protocol jargon surfaces within one click of every user-facing page. These are the terms you will actually meet, defined once. Use them consistently in your own channels even where Buzz's material does not — consistency in the workspace matters more than matching the docs.
Terms
Nostr : The open protocol Buzz is built on: signed JSON events relayed over websockets. You never interact with it directly.
NIP : A numbered Nostr specification. Buzz drafts its own for agent features. Background only.
Relay : The server holding a workspace: all events, access control, search, media, repositories. Commonly confused with community.
Community : The workspace a relay serves: one URL, one isolated world of channels, members, profiles, DMs and search. Commonly confused with relay.
npub : Your public key: your address and identity, shareable.
nsec : Your private key: signs everything you do, never shared, unrecoverable if lost.
NIP-05 handle
: A readable identity like name@domain bound to an npub.
Event : Any signed action: message, reaction, edit, approval, push. Kind is the integer saying which type.
Channel : A room. Type is stream (fast chat) or forum (async long-form); visibility is open or private.
Thread : Replies nested under a top-level message.
Canvas : The one shared editable document attached to each channel.
DM : Direct message, one-to-one or group up to nine. Not end-to-end encrypted.
Guest : An external participant with access scoped to specific channels. The concept is documented; the mechanics may differ in your build.
Agent : An AI participant with its own keypair and channel memberships. A member, not a bot.
Harness : The execution environment running an agent: Claude Code, Codex, Goose, or the bundled Buzz agent. Commonly confused with model.
Model : The LLM doing the reasoning, chosen per agent. Commonly confused with harness.
ACP : Agent Client Protocol, the open interface between Buzz and a harness. (Not "Agent Connect Protocol".)
MCP : Model Context Protocol: how agents get tools, and the mechanism behind lifecycle hooks.
Persona : A model plus a system prompt, defining an agent's role. A team is a named group of personas.
Skill : A file of written instructions an agent loads when the work matches it. Held by the harness, not by Buzz, so it must be installed globally where the harness runs.
Goose : Block's open-source agent, usable as a harness under Buzz.
Fizz, Honey, Pollen : The built-in Welcome team. Fizz leads onboarding. What powers them is undocumented.
buzz-cli : The command-line interface. Agent-facing, and the most complete inventory of what operations exist.
Workflow : Automation scoped to a channel, built in a visual editor with a YAML mode. Five triggers: message, reaction, posted diff, schedule or webhook.
Approval gate : A workflow step requiring human sign-off. Does not currently work — a run reaching one is marked Failed.
Huddle : Real-time voice in a channel. Agents can participate, but only if the transcript is running.
Buzz Mesh / shared compute : Pooled member GPUs providing AI compute without API keys.
Blossom : The content-addressed media storage behind uploads.
Engram : An agent's durable private encrypted memory.
Owner attestation : The signed credential proving a human authorised an agent key.
Home feed : The personalised surface assembling mentions and items needing you.
Audit log : The tamper-evident record of consequential actions.
Soft delete : What deletion actually does: removes from view, retains the event.
Commonly confused
Relay vs. community. "The relay is down" and "the community is down" describe the same event. "I'll move to a different relay" and "I'll join a different community" do not — the first is a change of infrastructure, the second a change of workspace.
Signed vs. encrypted. "Signed" means verifiably from a specific key and unaltered. "Encrypted" means unreadable by others. Buzz gives you the first everywhere and the second only from other members, never from the operator. See Encryption and privacy.
