Module acp 

domain::acp — the protocol-neutral ACP value objects.

The ACP v1.25.0 schema is the wire format this module speaks, but the value objects here are protocol-neutral IR — they are the consumer’s view of an ACP peer, not the wire types the per-revision codec generates. The wire types come from crates/protocol-droid-schema (the vendored schema is digested in crates/protocol-droid-schema/spec/MANIFEST.toml).

This module currently ships:

• version::AcpVersion — the pinned ACP release, ordered by (major, minor, patch). Unknown future releases are Unknown { major, minor, patch }.
• protocol_version::AcpProtocolVersion — the wire-level u16 initialize exchanges.
• implementation::Implementation — the clientInfo / agentInfo block.
• initialize::InitializeRequest and initialize::InitializeResponse — the initialize round-trip, plus the ClientCapabilities / AgentCapabilities shapes the request/response carry.
• method::AcpMethod — the 25 methods the v1.25.0 meta.json lists (13 agent, 11 client, 1 protocol).
• feature::AcpFeature and feature::AcpFeatureProfile — the per-feature bitset the dispatcher gates against.

What is not yet here:

• The session lifecycle types (session/new, session/load, session/prompt, session/cancel, session/list, session/delete, session/resume, session/close, logout).
• The slash-separated method params and the streaming update model.
• The SessionCapabilities, ClientSessionCapabilities, ElicitationCapabilities, and the rest of the capability sub-types the schema names.
• The application-layer dispatch and the per-revision wire codec.
• The stdio transport adapter.

This module is feature-gated behind acp-experimental at the crate level. The ACP module is post-MVP and experimental; the gate keeps the protocol-neutral core lean for consumers who never touch ACP.

Modules

content

ContentBlock — the typed content the session/prompt and session/update paths carry.

feature

AcpFeatureProfile — the ACP capability bitset, derived from the negotiated version × agent capabilities × client capabilities × transport.

implementation

Implementation — the clientInfo / agentInfo block the editor and the agent exchange in initialize.

initialize

initialize — the editor’s first call, the agent’s first reply.

method

AcpMethod — every method the ACP v1.25.0 schema names.

notification

domain::acp::notification — the session/update notification the agent streams to the client while processing a session/prompt turn.

protocol_version

AcpProtocolVersion — the wire-level protocol version.

session

domain::acp::session — the session lifecycle request / response types.

tool_call

domain::acp::tool_call — the tool call shapes the session/update notification’s tool_call and tool_call_update variants carry.

version

AcpVersion — the pinned ACP release, as a value object.
