Pull Request Overview

This PR introduces a chat functionality for insights data, implementing a multi-agent system that routes user queries to appropriate data sources and tools. The system uses Amazon Bedrock for AI processing and connects to Tinybird for data retrieval.

• Implements a three-agent architecture (router, text-to-sql, pipe) for handling different types of queries
• Adds streaming chat endpoints with integration to Model Context Protocol (MCP) for Tinybird
• Includes comprehensive prompt templates for SQL generation and tool routing

• The model identifier "us.anthropic.claude-sonnet-4-20250514-v1:0" appears to reference Claude Sonnet 4 from May 2025, which would be after my knowledge cutoff. Please verify this model exists in Amazon Bedrock or use a known model identifier.

The reasoningConfig with budgetTokens appears to be a provider-specific feature that may not be available in all Amazon Bedrock models. Consider adding error handling or documentation about which models support this feature.

	return {
	bedrock: {
	reasoningConfig: { type: "enabled", budgetTokens: 3000 },

	/**
	* Returns provider-specific options for Bedrock models.
	* Note: reasoningConfig with budgetTokens is only supported by certain Bedrock models (e.g., Anthropic Claude 3).
	* If the model does not support this feature, it will be omitted.

	protected getProviderOptions(input: TextToSqlAgentInput): any {
	const model = input.model;
	// Check if model supports reasoningConfig (assume a property or method, e.g., supportsReasoningConfig)

The replaceAll method with regex was added in ES2021. For broader compatibility, consider using replace with the global flag: text.replace(/```json\s*\n?/g, '')

Suggested change

	let cleanText = text.replaceAll(/```json\s*\n?/g, "");
	cleanText = cleanText.replaceAll(/\n?```/g, "");
	let cleanText = text.replace(/```json\s*\n?/g, "");
	cleanText = cleanText.replace(/\n?```/g, "");
