Overview

The Autohand ACP adapter bridges Autohand CLI with editors that support the Agent Client Protocol, like Zed. This gives you access to Autohand's powerful AI capabilities without leaving your editor.

What you get:

  • AI-powered code generation and editing directly in Zed
  • Context-aware assistance that understands your entire codebase
  • Seamless integration with Autohand's tool ecosystem
  • Configurable permissions and safety controls

Prerequisites

Before setting up the integration, make sure you have:

Verify your Autohand installation:

Installation

Step 1: Install the ACP adapter

Install the Autohand ACP adapter globally:

Step 2: Verify the installation

Step 3: Configure Zed

Zed can launch the adapter via the Agent Server extension. Add the following to your Zed settings or use the extension configuration:

Tip: The adapter includes an extension.toml that points to GitHub release assets for easy installation via Zed's extension system.

Configuration

Environment variables control how the adapter launches Autohand. Set these in your shell profile or Zed's environment configuration.

Basic settings

Variable Default Description
AUTOHAND_CMD autohand Path or command name for Autohand
AUTOHAND_CONFIG ~/.autohand/config.json Path to Autohand config file
AUTOHAND_MODEL - Override the model (--model)
AUTOHAND_TEMPERATURE - Override the temperature (--temperature)

Permission modes

Control how Autohand handles actions that require approval:

Mode CLI Flag Behavior
auto (default) --yes Auto-confirm risky actions
restricted --restricted Deny dangerous operations
unrestricted --unrestricted Allow all operations without prompts
ask none Prompt for each action (may hang)

Set the permission mode:

Advanced settings

Variable Default Description
AUTOHAND_DRY_RUN false Set to 1 to add --dry-run
AUTOHAND_AUTO_COMMIT false Set to 1 to add --auto-commit
AUTOHAND_EXTRA_ARGS - Extra CLI arguments (space-separated)
AUTOHAND_INCLUDE_HISTORY false Set to 1 to include prior turns
AUTOHAND_HISTORY_LIMIT 6 Max turns to include in history
AUTOHAND_MAX_HISTORY_CHARS 8000 Max history characters to include

Using Autohand in Zed

Starting a session

Once configured, Autohand appears as an available agent in Zed's AI panel. Select it and start chatting:

Best practices

  • Be specific: Describe exactly what you want. Include file paths when relevant.
  • Use restricted mode for exploration: When browsing code or asking questions, restricted mode prevents accidental changes.
  • Enable history for complex tasks: Set AUTOHAND_INCLUDE_HISTORY=1 for multi-turn conversations.
  • Review changes: Use --dry-run to preview changes before applying them.

Example prompts

Troubleshooting

Adapter doesn't start

Check: Is Node.js 18.17+ installed?

Session hangs or stalls

Cause: Autohand may be waiting for interactive input.

Solution: Make sure AUTOHAND_PERMISSION_MODE is not set to ask. Use auto, restricted, or unrestricted.

Missing configuration

Cause: Autohand config file doesn't exist or is incomplete.

Solution: Run Autohand interactively once to complete setup:

Each prompt loses context

Cause: By default, each ACP prompt starts a fresh Autohand process.

Solution: Enable history to carry context between turns:

Limitations

  • Non-interactive mode: Autohand runs without interactive prompts. If it needs input (e.g., missing config), the run will stall.
  • Tool permissions: ACP tool-level permission prompts are not surfaced to the editor. Use AUTOHAND_PERMISSION_MODE to control approvals.
  • Fresh process per prompt: Each ACP prompt starts a new Autohand process. Enable AUTOHAND_INCLUDE_HISTORY for basic continuity.
  • No streaming UI: Progress indicators and intermediate output depend on the editor's ACP implementation.
