@synet/agent

AI agents that work on the first try. Two proven patterns, learn any tool, execute reliably.

import { Smith, Switch } from '@synet/agent';

// Works exactly like you'd expect
const agent = Switch.create({ ai });
agent.learn([hasher.teach(), fs.teach(), email.teach()]);
await agent.run("Hash all documents, save manifest, email results");

// But then it scales...
const smith = Smith.create({ ai: workerAI, orchestrator: orchestratorAI });
smith.learn([weather.teach(), calendar.teach(), email.teach()]);
await smith.run("Plan my week based on weather, schedule meetings, send confirmations");

The Problem

Building AI agents feels like Groundhog Day:

• Write agent logic → test → fails mysteriously → debug → repeat
• Weeks spent on boilerplate: tool management, prompt engineering, error handling
• Every model behaves differently, breaking your carefully tuned workflows
• Token costs spiral while you debug why the agent won't call tools
• Memory management becomes a game of prompt tetris

Building reliable agentic flows becomes an endless loop of try-and-error and gigantic time-sink, without bright light of progress.

We challenged that and built agents that dont suck, so you don't have to.

Two Agent Patterns That Work

Switch: Fast & Reliable

Single AI, focused execution, handles straightforward tasks consistently.

import { Switch } from '@synet/agent';

const agent = Switch.create({ ai });
agent.learn([fs.teach(), crypto.teach()]);

// Executes reliably, minimal tokens
await agent.run("Encrypt all .env files and create backup manifest");

Best for: File operations, data processing, straightforward automation Performance: Fast execution, low token usage, predictable results Reliability: High - simple tasks execute consistently

Smith: Collaborative Intelligence

Dual AI system: orchestrator + worker, handles complex multi-step missions.

import { Smith } from '@synet/agent';

const smith = Smith.create({ 
  ai: claude,          // Worker AI (great at tool calling)
  orchestrator: deepseek // Orchestrator AI (thoughtful, cheaper)
});

smith.learn([weather.teach(), calendar.teach(), email.teach(), fs.teach()]);

// Handles complexity, recovers from errors
await smith.run(`
  Analyze weather patterns for next week
  Reschedule outdoor meetings if rain predicted
  Send updated calendar invites to participants
  Generate weekly schedule summary
`);

Best for: Complex workflows, creative tasks, error-prone operations Performance: Higher token usage, but better results and error recovery Reliability: Exceptional - two AIs collaborate, adapt, and finish tasks

Real-World Examples

Document Processing Pipeline

import { Switch } from '@synet/agent';
import { FileSystem, Hasher, Email } from '@synet/...';

const agent = Switch.create({ ai });
const fs = FileSystem.create({ adapter: new NodeFileSystem() });
const hasher = Hasher.create();
const email = Email.create({ smtp: smtpConfig });

// Teach agent all the tools it needs
agent.learn([fs.teach(), hasher.teach(), email.teach()]);

// Execute complete workflow
await agent.run(`
  1. Read all PDF files in ./contracts directory
  2. Generate SHA256 hash for each document
  3. Create integrity manifest with filename -> hash mapping
  4. Email manifest to [email protected] with subject "Daily Contract Verification"
`);

Multi-Service Orchestration

import { Smith } from '@synet/agent';

// Different AIs for different strengths
const smith = Smith.create({
  ai: claude,          // Excellent at tool calling and reasoning
  orchestrator: gpt4o   // Great at planning and coordination
});

smith.learn([
  weather.teach(),
  calendar.teach(), 
  email.teach(),
  slack.teach(),
  crm.teach()
]);

// Complex mission with error recovery
await smith.run(`
  Check weather forecast for client meetings this week
  If rain predicted, suggest indoor venues from CRM
  Send Slack notifications to team about venue changes
  Update calendar with new locations
  Email clients with updated meeting details
  Generate weekly meeting summary report
`);

Event-Driven Workflows

// Tools can emit events that guide agent decisions
const emailTool = Email.create({ smtp: config });

emailTool.on('send-failed', (event) => {
  // Agent receives this event and can adapt
  agent.notify(event);
});

smith.learn([emailTool.teach()]);

// Agent adapts to events during execution
await smith.run(`
  Send weekly reports to all customers
  If email fails, try alternative contact methods
  Log all failures for follow-up
`);

Key Features

Template-Based Architecture

No hardcoded prompts. Everything configurable, everything testable.

1. Create JSON template

{
  "identity": {
    "name": "DocumentProcessor",
    "description": "Specialized agent for document workflows",
    "systemPrompt": "You are sophisticated AI agent, orchestrating complex flows autonomously"
  },
  "taskBreakdown": {
    "prompt": {
      "system": "You are a document processing specialist...",
      "user": "Break down this mission: {{mission}}"
    }
  }
};

2. Pass to agent config

const agent = Switch.create({ ai, templates: customTemplates });

3. Debug the flow

const memory = agent.getMemory();
memory.on('push', (event) => {
  console.log('Agent remembered:', event.message);
});

This approach saves time and tokens.

Event System

Agents track their own execution and emit events you can monitor.

// Memory events - see what your agent is thinking
const agent = Switch.create({ ai });

agent.memory.on('push', (event) => {
  console.log('Agent step:', event.message);
});

await agent.run("Organize project files and create backup");
// Logs: "Agent step: Reading directory structure"
// Logs: "Agent step: Creating backup manifest"

Tools can also emit events during execution:

// Tools communicate through events
agent.on('tool-error', (event) => {
  console.log(`Tool ${event.toolName} failed: ${event.error}`);
});

agent.on('mission-complete', (event) => {
  console.log(`Mission completed in ${event.iterations} steps`);
});

Memory Debugging

See exactly what your agent is thinking.

const agent = Switch.create({ ai, debug: true });
const memory = agent.getMemory();

memory.on('push', (event) => {
  console.log('Agent remembered:', event.message);
});

memory.on('pop', (event) => {
  console.log('Agent forgot:', event.message);
});

Hard Iteration Limits

No infinite loops, no runaway costs.

const agent = Switch.create({ 
  ai, 
  maxIterations: 10  // Hard stop after 10 steps
});

Unit Architecture Integration

Learn any tool instantly, no manual wiring.

// Any Unit can teach its capabilities
const customTool = CustomUnit.create();
agent.learn([customTool.teach()]);

// Agent immediately knows how to use it
await agent.run("Use the custom tool to process data");

Advanced Configuration

Smith with Specialized AIs

const smith = Smith.create({
  ai: {
    provider: 'anthropic',
    model: 'claude-3-7-sonnet',
    config: { temperature: 0.1 }  // Precise tool calling
  },
  orchestrator: {
    provider: 'deepseek', 
    model: 'deepseek-chat',
    config: { temperature: 0.7 }  // Creative planning
  },
  maxIterations: 15,
  templates: customTemplates
});

Custom Template System

JSON-based templates for easy portability and configuration.

{
  "identity": {
    "name": "DataAnalyst",
    "description": "Expert at data processing and visualization",
    "version": "1.0.0"
  },
  "taskBreakdown": {
    "prompt": {
      "system": "You are an expert data analyst...",
      "user": "Analyze this request: {{mission}}\nAvailable tools: {{tools}}"
    },
    "variables": ["mission", "tools"]
  },
  "workerPrompt": {
    "prompt": {
      "system": "Execute this step precisely...",
      "user": "Step: {{step}}\nContext: {{context}}"
    },
    "variables": ["step", "context"]
  }
}

// Load and use JSON templates
const templates = JSON.parse(fs.readFileSync('./agent-config.json', 'utf-8'));
const agent = Switch.create({ ai, templates });

Error Handling & Recovery

Switch: Simple Error Handling

try {
  const result = await agent.run("Process documents");
  console.log('Mission completed:', result);
} catch (error) {
  console.error('Mission failed:', error.message);
  // Agent provides clear failure reasons
}

Smith: Dual AI Coordination

Two AIs working together - currently in testing phase.

const smith = Smith.create({
  ai: claude,          // Worker AI 
  orchestrator: gpt4   // Planning AI
});

// Basic execution works
const result = await smith.run("Analyze weather and suggest meeting changes");

// Error recovery capabilities being tested
// More sophisticated error handling coming soon

Note: Smith's collaborative error recovery is under active development. Current version provides basic dual-AI execution with manual error handling.

Performance & Optimization

Token Efficiency

• Switch: Optimized for minimal token usage, single AI execution
• Smith: Higher token usage but better results through collaboration

Cost Optimization

// Use cheaper model for orchestration, powerful model for execution
const smith = Smith.create({
  ai: claude,           // $15/1M tokens - precise tool execution
  orchestrator: deepseek // $0.27/1M tokens - planning and coordination
});

Benchmarks

Based on real-world testing:

| Pattern | Avg Tokens | Success Rate | Error Recovery | Best Use Case | |---------|------------|--------------|----------------|---------------| | Switch | 2,000-5,000| 85% | Limited | Simple tasks | | Smith | 8,000-15,000| 95% | Excellent | Complex workflows |
