## Introduction
ruv-swarm is a powerful WASM-powered neural swarm orchestration system that enhances Claude Code's capabilities through intelligent agent coordination.

🔥 **SPECIAL FEATURE: NO TIMEOUT MECHANISMS**
This version has ALL timeout and connection monitoring mechanisms completely removed for bulletproof infinite runtime.

## Quick Start

1. **Initialize a swarm:**
   \`\`\`bash
   mcp__ruv-swarm__swarm_init { topology: "mesh", maxAgents: 5 }
   \`\`\`

2. **Spawn agents:**
   \`\`\`bash
   mcp__ruv-swarm__agent_spawn { type: "researcher", name: "Doc Analyzer" }
   mcp__ruv-swarm__agent_spawn { type: "coder", name: "Implementation Expert" }
   \`\`\`

3. **Orchestrate tasks:**
   \`\`\`bash
   mcp__ruv-swarm__task_orchestrate { task: "Build a REST API", strategy: "adaptive" }
   \`\`\`

## Key Concepts

- **Agents**: Cognitive patterns that guide Claude Code's approach
- **Topologies**: Organizational structures for agent coordination
- **Memory**: Persistent state across sessions
- **Neural Training**: Continuous improvement through learning
- **🔥 INFINITE RUNTIME**: No timeout mechanisms whatsoever

## Best Practices

1. Always batch operations in a single message
2. Use memory for cross-agent coordination
3. Monitor progress with status tools
4. Train neural patterns for better results
5. 🔥 ENJOY INFINITE RUNTIME - NO TIMEOUTS!

## Removed Features (For Bulletproof Operation)
- ❌ Connection monitoring mechanisms
- ❌ Connection timeouts
- ❌ Activity monitoring
- ❌ Automatic disconnections
- ✅ Infinite runtime capability`

                text: `# Stability Features (NO TIMEOUT VERSION)

## Auto-Restart Protection
The production version includes built-in crash protection:

- **Maximum restarts**: 10 attempts
- **Restart delay**: 1 second between attempts
- **Reset window**: 5 minutes (restart count resets)
- **Graceful shutdown**: SIGTERM/SIGINT handling

## 🔥 TIMEOUT REMOVAL FEATURES

### What Was Removed:
- ❌ **Connection intervals**: No periodic connection checks
- ❌ **Connection timeouts**: No automatic disconnections
- ❌ **Activity monitoring**: No idle timeout tracking
- ❌ **Timeout environment variables**: MCP_CONNECTION_* vars removed

### What Was Preserved:
- ✅ **Security validation**: All security features intact
- ✅ **Error handling**: Proper error management
- ✅ **Process signals**: SIGTERM/SIGINT handling
- ✅ **Stability mode**: Auto-restart on crashes
- ✅ **Logging**: Full logging capability

## Usage
\`\`\`bash
# Enable stability mode (no timeouts)
ruv-swarm mcp start --stability

# For Claude Code integration (no timeouts)
claude mcp add ruv-swarm npx ruv-swarm mcp start --stability
\`\`\`

## Features
- Automatic process restart on crashes
- Proper signal handling
- Detailed logging of restart attempts
- Circuit breaker pattern to prevent infinite loops
- 🔥 **INFINITE RUNTIME**: Never disconnects due to timeout
- 🔥 **BULLETPROOF STABILITY**: No timeout-related failures

## Security Notes
- All security features from Issue #107 are preserved
- Input validation and sanitization maintained
- Command injection prevention intact
- WASM integrity verification preserved
- 🔥 **TIMEOUT VULNERABILITIES**: Eliminated by removing all timeout code`
