• Harness vs. Runtime: When to Graduate

  13 Jul, 2026

  Harness gives you a working agent in 20 seconds with 25 lines of configuration. Runtime takes 398 lines of code. Both run on the same compute. The graduation trigger that matters is not hooks or custom loops — it's per-user outbound identity.

• Build a Regression Suite for an Agent

  12 Jul, 2026

  I built a test suite for a support agent and found three classes of bugs that escape human review, output-quality scoring, and code review — and the regressions they taught me how to catch permanently.

• Two Ways to Authorize an Agent Tool: IAM or OAuth on Amazon Bedrock AgentCore Gateway

  11 Jul, 2026

  When you expose a tool to agents through an AgentCore Gateway, the real decision is who is allowed to call it — SigV4/IAM for callers inside your AWS boundary, or a JWT authorizer for everyone else. Here are the three patterns and when each fits.

• I Pointed an AI Code-Security Tool at My Own Control Plane

  9 Jul, 2026

  Corridor reviews AI-generated code inside the coding loop instead of after commit. I imported a real AWS control plane, planted an IDOR bug in a PR, and watched what it caught.

• How AgentCore Gateway Turns Any API Into an Agent Tool

  9 Jul, 2026

  AgentCore Gateway is a managed front door between agents and tools. It handles inbound auth, outbound auth, and protocol translation once, so any API or Lambda becomes an MCP tool that every connected agent can call. Here is how the wiring actually works.

• What Actually Gets Stored When You Put a Vector in S3 Vectors

  9 Jul, 2026

  A vector store keeps three things per record — a key, an array of floats, and a bag of metadata. Your document text is stored as metadata, and a 2 KB limit on the filterable part is what quietly breaks ingestion.

• Which Tier Does Your Vector Workload Live On?

  9 Jul, 2026

  Amazon S3 Vectors dropped the entry cost of vector storage on AWS to near zero. The question that matters now is which tier of the cost/latency curve your workload sits on — and why agents belong on the cheap one.

• Zed on Bedrock Makes the Agent Harness Portable

  6 Jul, 2026

  Wiring Zed to Amazon Bedrock turns Zed's agent harness into a provider-portable coding surface across the frontier models your account can reach.
