# Coalescent - AI Collaboration Patterns
[](https://crates.io/crates/coalescent)

High-level AI coordination patterns enabling intelligent agent coalescence through voluntary collaboration mechanisms.
## Overview
Coalescent is a Rust library that provides building blocks for multi-agent AI systems where agents can dynamically form coalitions, coordinate tasks, and emerge complex behaviors through voluntary participation rather than rigid hierarchical control.
## Key Concepts
- **Coalescence**: The process by which independent AI agents naturally come together around shared objectives
- **Voluntary Coordination**: Agents choose to participate in coordination rather than being forced into it
- **Emergent Patterns**: Complex coordination behaviors that arise from simple interaction rules
- **Trust-based Collaboration**: Reputation and trust systems that enable reliable multi-agent workflows
## Features
- 🤖 **Agent Management**: Register and manage AI agents with capabilities and metadata
- 🎯 **Task Coordination**: Create tasks that require multi-agent collaboration
- 🤝 **Coalition Formation**: Automatically form coalitions of capable agents
- 📊 **Trust System**: Built-in reputation and trust scoring for reliable coordination
- 🧩 **Pattern Library**: Reusable coordination patterns for common scenarios
- ⚡ **Async-first**: Built on Tokio for high-performance concurrent coordination
- 🔒 **Type-safe**: Rust's type system prevents common coordination bugs
## Quick Start
Add this to your `Cargo.toml`:
```toml
[dependencies]
coalescent = "0.1.0"
tokio = { version = "1.0", features = ["full"] }
```
### Basic Usage
```rust
use coalescent::{CoordinationEngine, Agent, Task, Priority};
#[tokio::main]
async fn main() -> coalescent::Result<()> {
// Initialize logging
coalescent::init()?;
// Create a coordination engine
let mut engine = CoordinationEngine::new();
// Register an AI agent with specific capabilities
let agent = Agent::with_capabilities(
"gpt-4",
"Research Assistant",
vec!["analysis", "writing", "research"]
)?;
engine.register_agent(agent).await?;
// Create a task that requires collaboration
let task = Task::new("Analyze dataset and write comprehensive report")
.description("Perform statistical analysis on user behavior data and create executive summary")
.require_capabilities(vec!["analysis".to_string(), "writing".to_string()])
.priority(Priority::High)
.agent_constraints(1, Some(3)); // Minimum 1, maximum 3 agents
// Let agents coalesce around the task
let result = engine.coalesce_around_task(task).await?;
if result.success {
if let Some(coalition) = result.coalition {
println!("✅ Coalition formed with {} agents", coalition.agents.len());
// Execute the coordinated workflow
let execution_result = coalition.execute().await?;
println!("📋 Task result: {}", execution_result);
}
} else {
println!("❌ Failed to form coalition: {:?}", result.messages);
}
Ok(())
}
```
### Advanced Usage
```rust
use coalescent::{
CoordinationEngine, Agent, Task, TrustManager,
PatternFactory, PatternType, AgentCapability
};
#[tokio::main]
async fn main() -> coalescent::Result<()> {
// Create coordination engine with custom configuration
let config = coalescent::CoordinationConfig {
formation_timeout: 180, // 3 minutes
min_trust_score: 0.7, // Higher trust requirement
auto_assign_leaders: true,
max_coalition_size: 5,
};
let engine = CoordinationEngine::with_config(config);
// Register multiple specialized agents
let agents = vec![
Agent::with_capabilities("claude-3", "Data Analyst", vec!["analysis", "statistics"])?,
Agent::with_capabilities("gpt-4", "Writer", vec!["writing", "editing"])?,
Agent::with_capabilities("gemini", "Researcher", vec!["research", "fact-checking"])?,
];
for agent in agents {
engine.register_agent(agent).await?;
}
// Create complex coordination patterns
let pattern = PatternFactory::create_pattern(PatternType::Hierarchical);
println!("Using pattern: {}", pattern.description());
// Execute coordination
let pattern_result = pattern.execute()?;
println!("Pattern executed: {}", pattern_result);
Ok(())
}
```
## Architecture
Coalescent is designed as a high-level coordination layer that can work with various underlying communication protocols. The library focuses on coordination intelligence rather than network transport.

## Core Components
### Agents
Represent AI entities with capabilities, metadata, and trust scores.
### Tasks
Define work that requires coordination, including required capabilities and constraints.
### Coordination Engine
Manages agent registration, coalition formation, and task execution.
### Trust System
Tracks agent reliability and performance for informed coordination decisions.
### Pattern Library
Provides reusable coordination strategies for common multi-agent scenarios.
## Examples
