Product announcement post from **Block Engineering** signed by **Thomas Petersen** (*Principal Designer & Builder*), published on **August 18, 2026**, ~1,800 words across thirteen short sections, introducing **Buzz Projects** — a **software forge hosted on its own relay**: Git repositories, branches, pull requests, issues, review and merge, multi-repo projects, an activity feed, all linked to conversation channels. The post's standfirst and thesis: *« Coding agents are the terminal for your computer. Buzz is the terminal for your network. »* Three contributions. **(A) A trust doctrine grounded in *ex post* proof rather than *ex ante* authorization**: on one side *« No forced guardrails, no limitations on what your agents are allowed to help you with »*, on the other *« Every push, review, approval, and merge is a signed Nostr event. If an agent authors a patch, you can see which agent produced it and which human authorized that agent to act »*; the section closes on a stated direction — *« we are already exploring ideas around agent trust protocols informed by past behavior »*. **(B) Git interoperability without proprietary tooling**: *« These are standard git repositories… You can fetch, clone, pull, and push over plain Smart HTTP, with no custom tooling or wrapper CLI required »*, with the clé Nostr serving as a single identity — *« The same npub that signs your messages signs your pushes. »* **(C) A distinction between execution surface and network presence**: *« A terminal gives an agent somewhere to execute commands and change files, but it does not give it a persistent place in the network. Buzz does. »* The post produces no figures and contains no outbound links; it qualifies itself as preliminary six times (*« still very basic »*, *« fairly elementary »*, *« still under experiments »*), and Projects lives under the **Experiments** tab of Buzz Desktop.

Tech-watch note by **Didier Girard** dated **August 2, 2026**, prompted by a colleague's question ("what is ACP?") to address a problem that is not terminological but **documentary**. **Three protocols compete for the acronym**, with no technical overlap whatsoever: **Agent Client Protocol** (client ↔ agent — Zed, August 2025, JSON-RPC 2.0 over stdio, Apache-2.0, "what LSP did for languages"), **Agentic Commerce Protocol** (agent ↔ merchant — OpenAI + Stripe, Sept. 29, 2025, competing with Google's **UCP** of Jan. 11, 2026 backed by **AP2**), and **Agent Communication Protocol** (agent ↔ agent — IBM Research / BeeAI, marginal but polluting searches). **The core of the note is not the disentangling but its observed failure**: the author searches "ACP" in their tech-watch knowledge base and gets **twelve results, all about the commerce protocol, zero about Zed's** — *"our watch agents had indexed the acronym without disambiguating it"*. Hence a knowledge-engineering rule: ***"a bare acronym is never indexed"*** — the entity is "Agent Client Protocol", "ACP" is **only an alias**, carried by three distinct entities. A structuring clarification follows (**MCP connects an agent to its tools, ACP connects a client to an agent; the two stack**), then the textbook case: **Buzz**, published by **Block** on July 21, 2026 under Apache-2.0 — a self-hostable workspace built on **Nostr**, where every human or agent participant is a **key pair** and every message, workflow step, or git push is a **signed event** in an append-only log. An entirely protocol-based architecture (`buzz-acp` an ACP harness over stdio, `buzz-agent` an ACP agent calling an LLM, `buzz-dev-mcp` an MCP shell + editing server), hence agent agnosticism: **Goose, Claude Code, and Codex** plug in through the same harness, and **Hermes** (Nous Research) connected to it without Block writing a single line — *"N+M instead of N×M, running in production"*. The note closes on the question of the **Claude subscription** versus third-party agents, with a five-stage 2026 timeline and a **design rule** that holds beyond this case: the line is not legal but **architectural** — ***"who is consuming, and on whose behalf"*** (an `owner-only` agent consumes your subscription on your behalf; an `anyone` agent in a shared channel routes your colleagues' requests through your account). **Verification carried out on this corpus**: the thesis holds, and more starkly than the note claims — not only is "Agent Client Protocol" **completely absent**, but the bare acronym `ACP` **is already typed as an entity** in two fiches, and the KB page `Agentic-Commerce-Protocol` **already attributes the protocol to Google** when it belongs to OpenAI + Stripe. The collision described is not a future risk: it has **already produced an attribution error** in the graph.
**Didier Girard** — auteur de la note. Écrit ici depuis la position de **praticien de la veille outillée** : le déclencheur est une question de collègue · le matériau principal est le comportement observé de sa propre base de connaissances · et la conclusion est une **règle de curation** adoptée en interne. Le texte alterne donc deux voix — l'explicateur de protocoles et l'ingénieur de la connaissance qui constate un défaut chez lui et en tire une norme.
