Feasibility spike: keep buzz-agent's ACP wire contract exactly as-is, but replace the hand-written agent loop with goose used as a Rust library. 13,259 -> 1,562 src LOC (88% cut), plus ~5,800 test LOC that covered the deleted loop. Deleted, now goose's: llm.rs 3846 -> goose::providers (superset of the 4 providers) mcp.rs 1139 -> goose::agents::extension_manager auth.rs 845 -> goose::providers (incl. Databricks OAuth) hints.rs 726 -> prompt_manager::with_hints catalog.rs 631 -> goose::providers::init builtin.rs 575 -> goose skills platform extension handoff.rs 430 -> goose::context_mgmt (auto-compaction) Kept deliberately (the contract buzz-acp depends on): wire.rs 293 verbatim; agentInfo.name = "buzz-agent" (kind-44200 harness attribution); 6-method surface; activeRunId with _meta nested inside update; usage_update before the session/prompt response; keepalive ticker; error -> JSON-RPC code mapping; single-flight; size caps. This is NOT "goose as the harness". Picking Goose from the harness gallery still shells out to a user-installed goose CLI. This is buzz-agent's own identity with a goose-powered loop. Why a separate crate excluded from the workspace: crates/buzz-agent is a library linked into sprig AND desktop/src-tauri, so goose's ~700-crate graph would land in the Tauri build and the workspace lockfile. Own Cargo.lock, same isolation trick as PR #1526. Notable: driving the library is what makes the persona work at all. Goose's own ACP server never reads systemPrompt (zero hits in goose/crates/goose/src) and both PRs that would have wired it -- buzz#1290, goose#9971 -- are closed unmerged. tests/stdio_turn.rs asserts Fizz's prompt reaches the provider. Also: GOOSE_MODE is left at goose's default rather than forced to "auto" (auto-approve every tool call), which is what the desktop catalog ships for the external goose runtime.

# buzz-agent-core — buzz-agent's ACP wire layer on top of the Goose Rust
|
|
# library (used as an SDK, not as a subprocess).
|
|
#
|
|
# WHY A SEPARATE CRATE, EXCLUDED FROM THE WORKSPACE
|
|
#
|
|
# `crates/buzz-agent` is a *library* linked into both `crates/sprig` and
|
|
# `desktop/src-tauri` (which uses only `catalog`/`config` for the Databricks
|
|
# model picker). Adding goose to that crate would pull goose's ~700-crate
|
|
# dependency graph into the Tauri app and into the workspace lockfile.
|
|
#
|
|
# So this crate is excluded from the workspace (see the root Cargo.toml
|
|
# `exclude` list) and carries its own Cargo.lock, exactly as PR #1526 did for
|
|
# `goose-acp`. Goose's ACP/MCP dependency versions move independently.
|
|
#
|
|
# Build: cargo build --release --manifest-path buzz-agent-core/Cargo.toml
|
|
#
|
|
# THIS IS NOT "GOOSE AS THE HARNESS". The binary keeps buzz-agent's identity
|
|
# (`agentInfo.name = "buzz-agent"`), its 6-method ACP surface, its
|
|
# `activeRunId` steering contract and its `usage_update` ordering. Only the
|
|
# agent loop underneath is Goose's instead of hand-written. Picking "Goose"
|
|
# from the harness gallery remains a separate thing: that shells out to a
|
|
# user-installed `goose` CLI.
