Agent Client Protocol Skill

The Agent Client Protocol (ACP) is a standardized communication framework between code editors (IDEs) and AI coding agents, similar to how the Language Server Protocol (LSP) unified language server integration. ACP enables any compatible agent to work with any compatible editor without custom integrations.

Core Value Proposition: Build once, run everywhere - agents implementing ACP work with any compatible editor, and editors supporting ACP gain access to all ACP-compatible agents.

When to Use This Skill

This skill should be triggered when:

• Building AI coding agents that need editor integration
• Implementing ACP support in code editors or IDEs
• Creating tool call handlers for agent operations
• Managing file system operations from agents
• Implementing session management for AI assistants
• Building bridges between existing agents and ACP clients
• Understanding JSON-RPC messaging for agent-editor communication
