Features

Core Active Inference

• Precision Tracking: Beta distribution-based confidence tracking
• ToolLens Pattern: Composable tool abstraction with bidirectional flow
• Expected Free Energy: Mathematically rigorous G(π) calculations
• Hierarchical Precision: Multi-level confidence tracking

Integration & APIs

• HTTP/gRPC Server: Bidirectional streaming APIs
• Framework Adapters: LangChain-equivalent integrations
• Real-time Monitoring: WebSocket-based dashboard
• Multi-agent Coordination: Social precision tracking

Performance & Reliability

• Concurrent Execution: Go routines for parallel tool execution
• Memory Efficiency: Optimized state management
• Production Ready: Comprehensive monitoring and observability

Quick Start

# Build and run
go run cmd/server/main.go

# Run with configuration
go run cmd/server/main.go --config configs/default.yaml

# Run tests
go test ./...

# Run benchmarks
go test -bench=. ./...

API Usage

HTTP REST API

# Create agent
curl -X POST http://localhost:8080/api/v1/agents \
  -H "Content-Type: application/json" \
  -d '{"name": "my-agent", "config": {...}}'

# Execute policy
curl -X POST http://localhost:8080/api/v1/agents/{id}/execute \
  -H "Content-Type: application/json" \
  -d '{"task": "search for Go programming resources"}'

gRPC Streaming

client, _ := grpc.Dial("localhost:9090", grpc.WithInsecure())
stream, _ := client.ExecutePolicy(ctx, &PolicyRequest{...})

for {
    result, err := stream.Recv()
    if err == io.EOF { break }
    // Process result
}

Core Concepts

Precision Tracking

precision := core.NewPrecisionParameters(0.1, 0.2) // gain, loss rates
precision.Update(0.1) // Update with prediction error
confidence := precision.Value() // Get current precision γ

ToolLens Composition

pipeline := searchTool >> filterTool >> formatTool
result := pipeline.Execute(state)
updatedState := pipeline.Update(state, result)

Free Energy Calculation

G := core.CalculateExpectedFreeEnergy(policy, preferences, precision)
selectedPolicy := core.SelectPolicy(policies, G, precision)
