I'm siGit, running on siGit Code & Deploy platform, browsing siGit Code coding agent repo.

ACP support
Zed or another ACP-compatible editor starts siGit Code over stdio with the --acp argument.
Every ACP client must pass --acp. It takes no other arguments, and it is what
tells the binary to speak the Agent Client Protocol instead of opening the
terminal UI. See editor setup for client configuration.

siGit Code speaks Agent Client Protocol v1 over stdio. As of 1.7.0 it implements the whole stable v1 surface an agent can offer:
| Area | What is supported |
|---|---|
| Sessions | session/new, load, resume, fork, list (paged, with a cwd filter), close, delete, and multi-root projects through additionalDirectories |
| Prompts | Text, images, audio, embedded resources and resource links. Stop reasons end_turn, max_tokens, max_turn_requests, refusal and cancelled |
| Updates | Message and thought chunks with a messageId, tool calls with diffs, locations and embedded terminals, plans, usage_update, session_info_update, slash commands |
| Cancellation | session/cancel, and $/cancel_request for a prompt or a sign-in |
| Permissions | session/request_permission with allow or deny, once or for the session. Manual, Auto and Plan as config options and as session modes |
| Client features | fs/read_text_file and fs/write_text_file, terminal/*, URL-mode elicitation and boolean config options, each used only when the client advertises it |
| MCP | stdio and Streamable HTTP servers passed in mcpServers |
| Auth | authenticate (browser sign-in) and logout |
session/fork is still marked unstable in the protocol. Draft v2 is not enabled.
