# ACP Client for VS Code

A [Visual Studio Code extension](https://marketplace.visualstudio.com/items?itemName=formulahendry.acp-client) that provides a client for the [Agent Client Protocol (ACP)](https://agentclientprotocol.com/) — connect to any ACP-compatible AI coding agent directly from your editor.

## Features

- **Multi-Agent Support**: Connect to 11 pre-configured ACP agents or add your own
- **Single-Agent Focus**: One agent active at a time — seamlessly switch between agents
- **Per-Agent Session List**: Each agent in the Agents view is expandable into its previous sessions. Click a session to restore its history in the chat. Backed by `session/list` when the agent supports it, or by a local per-workspace cache otherwise.
- **Session Config Options**: Dynamic per-session selectors (mode, model, reasoning level, …) advertised by the agent are rendered automatically in the composer toolbar.
- **Interactive Chat**: Built-in chat panel with Markdown rendering, inline tool call display, and collapsible tool sections
- **Thinking Display**: See agent reasoning in a collapsible block with streaming animation and elapsed time
- **Slash Commands**: Autocomplete popup for agent-provided commands with keyboard navigation
- **Mode & Model Picker**: Switch agent modes and models directly from the chat toolbar (kept for agents that haven't migrated to Session Config Options yet)
- **File System Integration**: Agents can read and write files in your workspace
- **Terminal Execution**: Agents can run commands with terminal output display
- **Permission Management**: Configurable auto-approve policies for agent actions
- **Protocol Traffic Logging**: Inspect all ACP JSON-RPC messages with request/response/notification labels
