🚀 Lighthouse Unified Integration Guide

✅ FINAL IMPLEMENTATION: Unified registerTools() API

This document outlines the final implementation of Lighthouse integration through a unified registerTools() method that accepts both object and array formats.

🎯 Overview

Problem Solved: Seamless integration of Lighthouse tools without migration or special methods.

Solution: Enhanced registerTools() method that automatically detects and handles both:

• Object format: Record<string, SimpleTool> (existing compatibility)
• Array format: Array<{ name: string; tool: SimpleTool }> (Lighthouse compatibility)

🔧 Core Implementation

Method Signature

registerTools(tools: Record<string, SimpleTool> | Array<{ name: string; tool: SimpleTool }>): void

Automatic Format Detection

registerTools(tools: Record<string, SimpleTool> | Array<{ name: string; tool: SimpleTool }>): void {
  if (Array.isArray(tools)) {
    // Handle array format (Lighthouse compatible)
    for (const { name, tool } of tools) {
      this.registerTool(name, tool);
    }
  } else {
    // Handle object format (existing compatibility)
    for (const [name, tool] of Object.entries(tools)) {
      this.registerTool(name, tool);
    }
  }
}

🌟 Lighthouse Compatibility

Zod Schema Support

NeuroLink already supports Zod schemas in the SimpleTool interface:

type SimpleTool = {
  description: string;
  parameters?: ZodSchema; // Zod support already implemented
  execute: (params: ToolArgs, context?: ExecutionContext) => Promise<unknown>;
};

Example: Lighthouse Tool Integration

import { NeuroLink } from "@juspay/neurolink";
import { z } from "zod";

const neurolink = new NeuroLink();

// Lighthouse tools exported as array with Zod schemas
const lighthouseTools = [
  {
    name: "juspay-analytics",
    tool: {
      description: "Analyze Juspay merchant payment data",
      parameters: z.object({
        merchantId: z.string().describe("Merchant identifier"),
        dateRange: z.object({
          start: z.string().datetime(),
          end: z.string().datetime(),
        }),
        metrics: z
          .array(z.enum(["volume", "success_rate", "avg_amount"]))
          .optional(),
      }),
      execute: async ({ merchantId, dateRange, metrics }) => {
        // Lighthouse tool implementation
        return {
          merchantId,
          period: dateRange,
          analytics: {
            totalVolume: 125000,
            successRate: 0.987,
            avgAmount: 45.67,
          },
        };
      },
    },
  },
  {
    name: "payment-processor",
    tool: {
      description: "Process payment transactions",
      parameters: z.object({
        amount: z.number().positive(),
        currency: z.string().length(3),
        paymentMethod: z.enum(["card", "upi", "wallet"]),
      }),
      execute: async ({ amount, currency, paymentMethod }) => {
        return {
          transactionId: `txn_${Date.now()}`,
          status: "success",
          amount,
          currency,
          method: paymentMethod,
        };
      },
    },
  },
];

// Register Lighthouse tools using unified API
neurolink.registerTools(lighthouseTools);

// Use in AI generation
const result = await neurolink.generate({
  input: {
    text: "Show me payment analytics for merchant MERCH123 for the last week",
  },
  provider: "google-ai",
});

📊 Compatibility Matrix

Format	Type	Lighthouse Compatible	Backward Compatible	Status
Object	Record<string, SimpleTool>	⚠️ Requires conversion	✅ Yes	Existing
Array	Array<{ name: string; tool: SimpleTool }>	✅ Direct compatibility	✅ Yes	New

🔄 Migration Path

Existing Code

No changes required - object format continues to work:

// Existing code remains unchanged
neurolink.registerTools({
  myTool: { description: "...", execute: async () => {...} }
});

New Lighthouse Integration

Direct import using array format:

// Lighthouse tools can be imported directly
import { lighthouseAnalyticsTools } from "lighthouse-sdk";
neurolink.registerTools(lighthouseAnalyticsTools);

🚀 Benefits

1. Unified API: Single method for all tool registration needs
2. Zero Migration: Lighthouse tools work without conversion
3. Backward Compatibility: Existing code unchanged
4. Type Safety: Full TypeScript support for both formats
5. Zod Integration: Native support for Zod parameter validation
6. API Simplification: Removes need for separate methods

🧪 Testing Strategy

Format Detection Tests

describe("Unified registerTools()", () => {
  test("should detect object format", () => {
    neurolink.registerTools({ tool1: {...}, tool2: {...} });
    expect(neurolink.getCustomTools().size).toBe(2);
  });

  test("should detect array format", () => {
    neurolink.registerTools([
      { name: "tool1", tool: {...} },
      { name: "tool2", tool: {...} }
    ]);
    expect(neurolink.getCustomTools().size).toBe(2);
  });

  test("should support mixed registration", () => {
    neurolink.registerTools({ objectTool: {...} });
    neurolink.registerTools([{ name: "arrayTool", tool: {...} }]);
    expect(neurolink.getCustomTools().size).toBe(2);
  });
});

Lighthouse Integration Tests

describe("Lighthouse Integration", () => {
  test("should register Lighthouse tools with Zod schemas", () => {
    const lighthouseTools = [
      {
        name: "analytics",
        tool: {
          description: "Analytics tool",
          parameters: z.object({ merchantId: z.string() }),
          execute: async ({ merchantId }) => ({ data: merchantId }),
        },
      },
    ];

    neurolink.registerTools(lighthouseTools);
    const result = await neurolink.executeTool("analytics", {
      merchantId: "test",
    });
    expect(result.data).toBe("test");
  });
});

📚 Implementation Checklist

• Design: Unified method signature with union types
• Detection: Automatic format detection using Array.isArray()
• Compatibility: Zod schema support verification
• Documentation: Updated README and guides
• Implementation: Modify registerTools() method in NeuroLink class
• Cleanup: Remove redundant registerToolsFromArray() method (never existed)
• Testing: Update tests for unified method
• Validation: End-to-end integration testing

🔮 Future Extensibility

The unified approach supports future extensions:

// Future: Additional format support
registerTools(tools:
  | Record<string, SimpleTool>           // Object format
  | Array<{ name: string; tool: SimpleTool }>  // Array format
  | MCPServerConfig                      // Future: MCP server format
  | PluginManifest                       // Future: Plugin format
): void

This architecture ensures the API can grow with new tool formats while maintaining compatibility.
