# Collaboration Modes Design Document

## 🎯 Overview

Handoff AI's adaptive collaboration system allows users to choose how they want to work with AI based on project complexity, AI capability, and personal preference.

## 🚀 Core Collaboration Modes

### **1. `collaborate` Mode**
**When to use**: Complex projects, critical decisions, learning scenarios
**Behavior**: 
- AI asks clarifying questions before proceeding
- Validates assumptions with human
- Documents all decisions and reasoning
- Seeks approval for architectural choices
- Rich back-and-forth communication

**Example Interaction**:
```
AI: "I see you want to add authentication. I found two patterns in your codebase:
1. JWT with middleware (used in /api/users)
2. Session-based (used in /admin)

Which pattern should I follow for this new feature?"
```

### **2. `automatic` Mode**
**When to use**: Simple tasks, greenfield projects, routine work
**Behavior**:
- AI makes decisions independently
- Documents what it did and why
- Minimal human interruption
- Follows established patterns automatically
- Only asks for help when truly stuck

**Example Interaction**:
```
AI: "Added JWT authentication following your existing /api/users pattern. 
Created middleware, updated routes, added tests. 
Documented assumptions in .project/assumptions.md"
```

### **3. `guided` Mode**
**When to use**: Learning, team environments, structured decision-making
**Behavior**:
- AI presents options with pros/cons
- Human chooses, AI executes
- Educational explanations provided
- Good for knowledge transfer
- Structured decision points

**Example Interaction**:
```
AI: "For authentication, here are your options:
A) JWT (stateless, scalable, complex refresh handling)
B) Sessions (simple, server state, scaling challenges)
C) OAuth integration (secure, external dependency)

Which would you prefer? I can explain any option in detail."
```

### **4. `review-only` Mode**
**When to use**: High-trust scenarios, experienced developers, time pressure
**Behavior**:
- AI completes entire tasks
- Presents final result for review
- Human approves/rejects/requests changes
- Fastest execution, batch feedback
- Good for routine implementations

**Example Interaction**:
```
AI: "Authentication implementation complete. Review:
- Added JWT middleware ✓
- Updated 5 routes ✓  
- Added 12 tests ✓
- Updated documentation ✓

Approve to merge, or request specific changes."
```

## ⚙️ Configuration System

### **Global Settings** (`.project/handoff-config.md`)
```yaml
# Default collaboration mode
default_collaboration_mode: collaborate

# Mode preferences by context
collaboration_modes:
  new_project: automatic
  existing_project: collaborate
  team_environment: guided
  solo_development: automatic
  
# AI capability trust level (affects mode suggestions)
ai_trust_level: medium # low | medium | high
```

### **Per-EPIC Overrides**
```yaml
# EPIC-specific collaboration modes
epic_modes:
  feature-implementation: collaborate
  codebase-exploration: automatic
  codebase-improvement: guided
  collaborative-documentation: review-only
  release-management: guided
```

### **Dynamic Mode Switching**
```yaml
# Allow mode changes during execution
allow_mode_switching: true

# Auto-suggest mode changes based on context
smart_mode_suggestions: true

# Learn from user preferences over time
adaptive_learning: true
```

## 🧠 Smart Mode Selection

### **Context-Based Defaults**
```javascript
function suggestCollaborationMode(context) {
  const factors = {
    projectAge: context.isNewProject ? 'automatic' : 'collaborate',
    complexity: context.taskComplexity > 7 ? 'collaborate' : 'automatic',
    teamSize: context.teamSize > 1 ? 'guided' : 'automatic',
    userExperience: context.userLevel === 'junior' ? 'guided' : 'collaborate',
    aiTrustLevel: context.aiTrust === 'high' ? 'automatic' : 'collaborate'
  };
  
  return calculateBestMode(factors);
}
```

### **Learning System**
- Track mode effectiveness (user satisfaction, task completion)
- Suggest mode changes based on patterns
- Adapt to user preferences over time
- Learn project-specific optimal modes

## 🎪 Mode Transition Examples

### **Collaborate → Automatic**
```
Human: "This is working well, you can handle the rest automatically"
AI: "Switching to automatic mode. I'll complete the remaining tasks and document my decisions."
```

### **Automatic → Collaborate**
```
AI: "I encountered an architectural decision that affects multiple systems. 
Switching to collaborate mode for your input."
```

### **Guided → Review-Only**
```
Human: "I trust your judgment on these routine changes"
AI: "Switching to review-only mode. I'll batch the remaining changes for your review."
```

## 🔄 Implementation Phases

### **Phase 1: Basic Modes** (v0.4.0)
- Implement 4 core modes
- Basic configuration system
- Manual mode switching
- Update EPICs to respect modes

## 🎯 Future Evolution

### **AI Capability Growth**
```
Today:     70% collaborate, 20% guided, 10% automatic
6 months:  50% collaborate, 30% guided, 20% automatic
1 year:    30% collaborate, 30% guided, 40% automatic
2 years:   20% collaborate, 20% guided, 60% automatic
```

### **New Modes (Future)**
- **`mentor`**: AI teaches while working
- **`pair`**: Real-time collaborative coding
- **`audit`**: AI reviews and suggests improvements
- **`research`**: AI explores and reports findings

## 🛠️ Technical Implementation

### **Mode Detection**
```javascript
class CollaborationModeManager {
  getCurrentMode(context) {
    return this.resolveMode({
      globalDefault: this.config.default_collaboration_mode,
      epicOverride: this.config.epic_modes[context.epic],
      userPreference: this.userPrefs.preferred_mode,
      contextSuggestion: this.suggestMode(context)
    });
  }
  
  switchMode(newMode, reason) {
    this.logModeChange(this.currentMode, newMode, reason);
    this.currentMode = newMode;
    this.notifyUser(`Switched to ${newMode} mode: ${reason}`);
  }
}
```

### **Mode-Aware AI Behavior**
```javascript
class AIAgent {
  async processTask(task, mode) {
    switch(mode) {
      case 'collaborate':
        return await this.collaborativeProcess(task);
      case 'automatic':
        return await this.automaticProcess(task);
      case 'guided':
        return await this.guidedProcess(task);
      case 'review-only':
        return await this.reviewOnlyProcess(task);
    }
  }
}
```
