Research direction

Start by locating the existing MCP and headless integrations, then review the ACP requirements for editor-agent communication. Done should mean Command Code can be launched by ACP-compatible editors with the requested agent interaction, permission approvals, and resumable sessions.

Written by the indexing model from the issue text.

Description

Feature Description

Command Code currently integrates with editors via MCP or headless mode(cmd -p --output-format json), but it cannot be embedded as an agent in editors/IDEs that speak the Agent Client Protocol (ACP). ACP is becoming the de-facto standard for editor–agent communication and is already supported by Zed, JetBrains IDEs, and Typstify, with adapters for Claude Code, Codex, OpenCode, and Cline.

Use Case

I write Typst documents in Typstify, whose v1.8.0 AI Assistant launches any ACP agent and augments it with editor-aware MCP tools: getActiveDocument, getDocumentOutline, queryDiagnostics, typstCompiler (PDF/PNG/SVG export), previewer control, and TPIX package search/download. Configuring Command Code as the agent would let me use its models, taste learning, skills, and plan mode directly inside the editor - with permission approvals in the UI and sessions I can resume - instead of switching to a terminal for every task.
