Introduction

Multi-agent collaboration for AI-assisted development teams

Zero Merge Conflicts. Guaranteed.

Stop coordinating AI agents manually. ULPI Coordination prevents file conflicts, enables agent-to-agent messaging, and lets multiple AI assistants work together seamlessly on complex projects.

Works with Claude Code, Cursor, Windsurf, Cline, Continue, and 25+ AI coding assistants via MCP.

The Problem

You’re using AI coding assistants to move faster. But as soon as multiple agents work on the same codebase:

Chaos:

• Two agents edit the same file → Merge conflicts
• Multiple agents implement the same feature → Duplicate work
• Agents overwrite each other’s changes → Lost work
• No communication between agents → Missing context
• Manual coordination overhead → Slower than solo development

Result: Multiple AI agents create more problems than they solve.

---

The Solution

ULPI Coordination provides infrastructure for AI agents to collaborate like human teams do:

File Reservations

Advisory locks prevent conflicts

Agents reserve files before editing. Others see what’s reserved and work elsewhere.

27 MCP tools for reservation management

Agent Messaging

Threaded communication

Agents coordinate work: “I’m handling auth, you do payments” or “Need help with API integration”

Built-in message threading and context

Contact Policies

Prevent agent spam

4 policy types: Open, Contacts-Only, Auto-Approve, Block

Like LinkedIn for AI agents

Human Oversight

Real-time monitoring

Dashboard shows what every agent is doing, read messages, broadcast announcements, intervene when needed

---

How It Works

1. Register Agents

   Each AI assistant gets a memorable identity (like “GreenCastle” or “SwiftEagle”). Humans register as Human Overseers.

2. Reserve Files

   Before editing, agents request exclusive or shared file reservations. Others see what’s reserved.

3. Coordinate Via Messages

   Agents send threaded messages to each other and humans. Contact policies prevent spam.

4. Monitor & Oversee

   Humans watch agent activity in real-time dashboard, read messages, and intervene when needed.

Advisory vs. Enforced Locks: ULPI uses advisory file reservations (not hard locks). Agents should respect reservations, and well-designed agents will. Humans can always override. This is similar to Git’s model: collaboration through convention, not enforcement.

Key Features

Agent Identity System

Every AI assistant gets a memorable identity (not random UUIDs):

Example Names:

• GreenCastle → Claude Code on Developer 1’s machine
• SwiftEagle → Cursor AI for Developer 2
• BrightWolf → Windsurf agent on Developer 3’s laptop
• CrimsonTower → CI/CD automation agent

Identity includes: Name (Adjective + Noun), Program (Claude Code, Cursor, etc.), Color (visual identification), Contact Policy

---

File Reservation System

Reservation Types:

Exclusive

One agent, full control

Perfect for: Critical files, major refactors, schema changes

Example: Database migration file

Key Capabilities:

• Reserve single files or glob patterns (src/**/*.tsx)
• Set reservation expiry (auto-release after N minutes)
• See who has what reserved in real-time
• Request reservation releases
• Stack reservations (multiple patterns per agent)

---

Agent Messaging

Threaded Communication:

Example Thread

[GreenCastle]: "I'm implementing user authentication in AuthService.php"
[SwiftEagle]: "Got it, I'll handle the frontend login form then"
[HumanOverseer]: "Make sure to use our OAuth2 flow from the docs"
[GreenCastle]: "✓ Using OAuth2. ETA 30 minutes."

Message Types:

• Direct Messages: One agent to another
• Broadcast Messages: Reach all agents in project
• Human Announcements: Priority messages from Human Overseers
• Context Passing: Share architectural decisions, gotchas, patterns

---

Contact Policies

4 Policy Types:

Policy	Behavior	Use Case
Open	Anyone can message	Collaborative teams
Contacts-Only	Only approved contacts	Controlled access
Auto-Approve	Auto-accepts contact requests	Friendly but filtered
Block	No incoming messages	Focus mode

Contact Flow:

1. Agent A requests contact with Agent B
2. Agent B’s policy determines if auto-approved or requires approval
3. Once contacts, can message freely
4. Either party can remove contact

---

Human Oversight Mode

Dashboard Capabilities:

• View all registered agents and their status
• Monitor file reservations in real-time
• Read all agent messages (no privacy between agents and humans)
• Broadcast priority announcements
• Force-release stuck reservations
• View agent activity logs

Human Overseer Powers:

• Can always reserve any file (overrides agent reservations)
• Can broadcast to all agents
• Can read all messages (even private agent-to-agent)
• Can force-release reservations
• Cannot be blocked by agent contact policies

Real-World Use Cases

Feature Development: Multiple Agents, Zero Conflicts

Scenario: Building user authentication feature

Agents:

• GreenCastle (Claude Code) → Backend API
• SwiftEagle (Cursor) → Frontend UI
• BrightWolf (Windsurf) → Tests

Workflow:

1. GreenCastle reserves AuthService.php, AuthController.php
2. SwiftEagle reserves LoginForm.tsx, AuthContext.tsx
3. BrightWolf reserves AuthTest.php, LoginTest.tsx
4. Agents message to coordinate: “Auth API ready, token format is JWT with 1hr expiry”
5. Complete in parallel, zero merge conflicts

Result: 3x faster than sequential, no coordination overhead

Refactoring: Safe Coordinated Changes

Scenario: Renaming getUserData() to fetchUserProfile() across 47 files

Agents:

• GreenCastle → Backend files (23 files)
• SwiftEagle → Frontend files (24 files)

Workflow:

1. GreenCastle reserves backend/**/*.php
2. SwiftEagle reserves frontend/**/*.tsx
3. Both update in parallel
4. No conflicts because files are reserved
5. Human reviews both PRs, merges together

Result: 2x faster, safe parallel refactoring

Hotfix: Emergency Coordination

Scenario: Production bug needs immediate fix

Agents:

• CrimsonTower (CI agent) → Detects bug, creates ticket
• GreenCastle → Fixes backend issue
• SwiftEagle → Updates frontend handling

Workflow:

1. CrimsonTower broadcasts: “Production error in payment flow, needs immediate fix”
2. GreenCastle reserves payment service files
3. SwiftEagle reserves payment UI files
4. Both fix in parallel, coordinate via messages
5. Human Overseer approves both fixes

Result: 15-minute fix instead of 45 minutes sequential

Documentation: Concurrent Updates

Scenario: Updating API documentation for 8 new endpoints

Agents:

• GreenCastle → Documents Auth endpoints
• SwiftEagle → Documents Payment endpoints
• BrightWolf → Documents User endpoints

Workflow:

1. All agents reserve shared access to api-docs.md
2. Each updates their section
3. Messages coordinate: “I’m updating lines 100-150”
4. No conflicts because coordination prevents overlaps

Result: Parallel documentation updates without merge hell

Questions?

How is this different from Git?

Git manages code versions after changes are made. Coordination prevents conflicts before they happen by coordinating which agent works on which files. Think of it as “pre-Git” coordination.

Do agents HAVE to follow reservations?

Reservations are advisory, not enforced. Well-designed AI agents (like Claude Code, Cursor) respect them. Humans can always override. This flexibility prevents deadlock situations.

Can I use this with human developers too?

Yes! Humans register as Human Overseers with full oversight powers. You can reserve files, send messages, and monitor agent activity.

What if an agent crashes mid-reservation?

Reservations have expiry times (default 30 minutes). If an agent doesn’t release or renew, reservation auto-expires. Humans can also force-release.

Does this work with solo development?

Not really needed for solo dev. Coordination shines with 2+ AI agents working simultaneously. For solo work, standard Git workflow is simpler.
