Daily recap for June 5, 2026

Today we shipped seven new production-grade AI tutorials for small businesses. They range from an automated return-reason agent for Shopify to a knowledge agent that answers PayPal transaction questions, plus behavioral email triggers, invoice processing, and customer support evaluation harnesses. Each tutorial includes a downloadable zip and a full walkthrough.

New tutorials

Cohere MCP Server for SMB Research and Summarization

This tutorial builds an MCP server that exposes Cohere's language models and search tools to AI agents, enabling automated research, summarization, and content generation. Small businesses can drop this server into any MCP client to give their agents research capabilities without writing custom API wrappers.

Databricks Agent Eval Harness for SMB Support Bots

This solution provides an automated regression testing pipeline for customer support agents, running on Databricks. It uses golden conversation datasets to score agent responses with a Databricks LLM, enforces quality gates, and exports results to Braintrust for analysis. SMBs can catch regressions before they affect customers.

Return Reason Agent for Shopify Merchants

Automate refund and RMA decisions for Shopify orders using a hybrid RAG pipeline and an agnostic LLM. When a return reason webhook fires, the agent classifies the issue, retrieves policy context, and decides whether to refund, replace, or escalate — cutting hours of manual review down to seconds.

Behavioral Email Trigger Agent for WooCommerce Merchants

This agent replaces calendar-based email schedules with real-time behavioral triggers. It monitors WooCommerce events — product views, cart abandons, purchases — and uses an LLM to decide which personalized email to send via Klaviyo, boosting engagement and sales for merchants.

Anthropic Knowledge Agent for PayPal SMB Transaction Insights

A knowledge agent that lets business owners ask natural-language questions about their PayPal transaction history — like 'What were my largest refunds last month?' — and get answers grounded in actual data via hybrid RAG and Anthropic Claude. No more manual report digging.

Under the hood: Anthropic Claude, @reaatech/hybrid-rag-pipeline, 108 tests, 99.6% coverage.

Azure AI Document Pipeline for Sage Intacct Invoice Automation

This document pipeline turns uploaded PDF invoices into structured Sage Intacct AR entries. It uses Azure OpenAI for extraction, a JSON repair step to fix malformed output, and confidence routing to flag low-confidence fields for human review, eliminating manual data entry.

xAI Grok Agent Eval Harness for SMB Support QA

A CI-friendly eval harness that uses xAI Grok as both the system under test and the judge. It runs batch evaluations against golden datasets, scores response quality and safety, and can gate deployments to prevent bad updates. Ideal for SMBs using Grok for customer support.
