We itemize the real monthly bill for one production AI agent — tokens, messaging, hosting, and monitoring — at July 2026 published prices, fully sourced.

Three documented AI agent incidents — Replit, Google Gemini CLI, and a Cursor agent — the root cause of each, and the control that would have prevented it.

We opened primary sources behind six named AI agent case studies, a withdrawn Big Four report, and two independent benchmarks to see what actually holds up.

Automation runs a fixed, predefined workflow. An AI agent is given a goal and decides its own steps. A sourced, plain-English guide with a comparison table.

A falsifiable six-part checklist for production-ready AI agent frameworks: pass/fail tests, official docs, failure math, and real July 2026 tooling prices.

What AI automation really costs a small business: attributed market price bands, monthly run costs, a three-year cost worksheet, and what blows budgets.

Vendor thresholds for build vs buy disagree by 100x. We derive the crossover formula from published prices and BLS wages so you can rerun the math yourself.

Gartner expects over 40% of agentic AI projects to be canceled by end-2027. Seven documented causes, each pinned to a named incident — and the missing control.
