Installation

Option 1: Clone & Symlink (Recommended for Development)

git clone https://github.com/YOUR_USER/pi-cursor.git
cd pi-cursor
pi install ./extensions

Option 2: Direct Clone to Extensions Directory

pi install https://github.com/YOUR_USER/pi-cursor.git

Option 3: Manual Installation

# Install Cursor CLI
curl https://cursor.com/install -fsS | bash

# Authenticate
agent login

# Create symlink
mkdir -p ~/.pi/agent/extensions
ln -sf /path/to/pi-cursor/extensions/cursor-acp.ts ~/.pi/agent/extensions/cursor-acp.ts

Setup Cursor CLI

1. Install the Cursor Agent CLI:

   curl https://cursor.com/install -fsS | bash
   

2. Authenticate:

   agent login
   

3. Verify installation:

   agent --version
   

Usage

Commands in pi

/cursor:connect     # Start Cursor Agent session
/cursor:mode agent  # Switch to agent mode (default)
/cursor:mode plan   # Switch to read-only planning mode
/cursor:mode ask    # Switch to Q&A mode
/cursor:disconnect  # End session
/cursor:help        # Show help

Tools

@cursor_agent(prompt, mode?)

Delegate a task to Cursor Agent.

Examples:

@cursor_agent Write a README for this project

@cursor_agent Plan: Analyze the codebase structure

@cursor_agent Fix the bug in src/auth/login.ts

cursor_status

Check if Cursor CLI is installed and authenticated.

cursor_disconnect

End the Cursor Agent session.

How It Works

pi → cursor-acp extension → agent acp (CLI process) → Cursor Cloud

The extension spawns an agent acp child process and communicates via JSON-RPC over stdio.

Troubleshooting

"Command not found: agent"

The Cursor CLI isn't installed. Run:

curl https://cursor.com/install -fsS | bash

"Authentication required"

Run agent login to authenticate with your Cursor account.

Extension not loading

Check that the symlink exists:

ls -la ~/.pi/agent/extensions/cursor-acp.ts
