Cursor needs to stop guessing names and check first

Dope.

Ive been working on Agent Orchitration Control Plane App all day.

Here is an earlier today version of my readme…

Its taking on a scope_kreep in just this afternoon and evening that its super fun and crazy.

Developing with YOLO is so fn fantastic.!!!

(also not that when you hit the “25 call limit” stall-warning:

EDIT, HAHA did it again:

Introducing the Cursor Agent Control Plane: Multi-Instance Collaboration with PostgreSQL

TL;DR

A PostgreSQL-based control plane that enables multiple Cursor IDE instances to work together seamlessly, sharing context, commands, and workspace state across machines.

The Vision

Imagine running Cursor on multiple machines, each instance aware of the others, sharing context, and working together seamlessly. That’s what the Cursor Agent Control Plane enables - a distributed system where Cursor instances become collaborative agents.

Architecture Overview

graph TB
    subgraph "Control Plane"
        PG[("PostgreSQL<br/>Source of Truth")]
        
        subgraph "Core Services"
            CMD["Command Queue"]
            SYNC["Sync Manager"]
            LOCK["Lock Manager"]
            CTX["Context Manager"]
        end
        
        subgraph "Monitoring"
            HEALTH["Health Check"]
            METRICS["Metrics"]
            LOGS["Event Log"]
        end
    end
    
    subgraph "Agent 1 (Machine A)"
        A1["Cursor Instance"]
        A1_WS["Workspace"]
        A1_COORD["Coordinator"]
    end
    
    subgraph "Agent 2 (Machine B)"
        A2["Cursor Instance"]
        A2_WS["Workspace"]
        A2_COORD["Coordinator"]
    end
    
    A1_COORD --> PG
    A2_COORD --> PG
    PG --> CMD & SYNC & LOCK & CTX
    CMD & SYNC & LOCK & CTX --> HEALTH & METRICS & LOGS

Key Features

Implementation Highlights

1. PostgreSQL as Source of Truth

-- Agent session management
CREATE TABLE cursor_control.agent_sessions (
    session_id UUID PRIMARY KEY,
    machine_name TEXT,
    workspace_path TEXT,
    capabilities JSONB,
    last_heartbeat TIMESTAMPTZ
);

-- Command queue
CREATE TABLE cursor_control.command_queue (
    command_id UUID PRIMARY KEY,
    source_agent UUID,
    target_agent UUID,
    command_type TEXT,
    payload JSONB,
    status TEXT
);

2. Python Coordinator

class CursorPgCoordinator:
    """PostgreSQL-based coordinator for Cursor agents"""
    
    def enqueue_command(self, target: str, command: str, payload: dict):
        """Send command to another agent"""
        
    def get_pending_commands(self) -> list:
        """Get commands waiting for execution"""
        
    def update_workspace_state(self, changes: list):
        """Sync workspace changes"""
