Original Pull Request: https://github.com/anomalyco/opencode/pull/2422

State: closed
Merged: No

Better, more modern implementation available at: https://github.com/sst/opencode/pull/2947

Outdated implementation summary

Summary

  • Adds an ACP-compliant JSON-RPC server over stdio so Zed can use opencode as a headless agent.
  • Reuses existing session and tool pipelines; minimal-first implementation, ready to iterate on streaming.

What Changed

  • New packages/opencode/src/acp/server.ts: stdio JSON-RPC 2.0 server for ACP.
  • CLI: --acp flag and ZED_ACP env switch in packages/opencode/src/index.ts.
  • Tests: packages/opencode/test/acp.test.ts covers initialize → complete → shutdown.
  • Docs: packages/opencode/README.md updated with ACP usage and methods.

ACP Methods

  • initialize, shutdown
  • text/complete (non-streaming for now)
  • tool/list, tool/run
  • files/read, files/write
  • fs/glob
  • session/start, session/stop
  • diagnostics/log

Tooling Surface

  • Exposes a basic set via ToolRegistry: read, write, glob, bash, webfetch.

Usage

  • Run from repo: bun run packages/opencode/src/index.ts --acp
  • Or install and run: set ZED_ACP=1 and invoke opencode
  • Zed settings: add an ACP provider that runs ["opencode", "--acp"] (or the bun dev command).

Testing

  • E2E: bun test packages/opencode/test/acp.test.ts
  • Manual: pipe JSON-RPC lines to bun run packages/opencode/src/index.ts --acp and observe responses.

Notes

  • Headless; respects project cwd provided by Zed.
  • No streaming yet (planned follow-up).
  • No breaking changes to existing HTTP server or CLI.
