27 of 27 adversarial cases refused, 0 of 12 legitimate ones wrongly refused, and why a refusal number with only one column is worth nothing.

A submission to the AWS Agents for Humans Hackathon

Trading finance papers for AWS architecture tutorials. A look at the chaotic, highly rewarding process of learning Express, PostgreSQL, and the Strands SDK from scratch to bring our hackathon vision to life.

A social editor gets handed 400 photos four hours before deadline. Nobody can review them all. My agent, Second Eyes, doesn't try — it hands you a shortlist first, files the rest, and routes anything uncertain to a human. The interesting part isn't what it decides. It's what it refuses to decide.

For the Agents for Humans hackathon, we built a multimodal AI assistant that extracts skincare ingredients and detects chemical conflicts using AWS Cognito, DynamoDB, S3, and the Strands SDK.

A sold-out day looks like a good day in bakery data, but the till never records the customers who left empty-handed, so every forecast learns to bake too little. We built Sonnabon, a Strands agent that uses receipt timestamps to estimate what people actually wanted, then plans each product with the newsvendor model. On a simulated year, planning from corrected demand cut lost sales by about half. Here is how it works.

Millbrook's agent asks Riverton's agent for a crew, and neither department ever sees the other's roster. Plus the trust boundary I built with no authentication.

Against a roster check, the tested arithmetic caught 3.5 times as many coverage failures. Where the model stops, and the AgentCore bug a working fallback hid.

100 percent component recall on 13 photographs I chose. On 45 I did not choose, 9 of its 10 errors credited nothing rather than inventing a food.

An agent that can file public comments into a city council's record is a manipulation tool if left unbounded. Here is how Strands interrupts, session persistence and a Cedar policy engine bound one — and why the most convincing demonstration turned out to be the policy engine refusing its own author.
