Our toolchain assumes one human writer, AI agents break that illusion
One Writer Our tools assume one writer, and assume that writer is a human. Nothing computes what a change reads and writes at runtime, so the only known fix is brute force priced for organizations. 27 Jul 2026 Six weeks ago I wrote The Test Suite Was the Incident: my test suite had grown a pile of shared data nobody owned, every pull request paid to rebuild it, and the resulting failures had nothing to do with the changes under review.

That cost me about $180 in one night. I got a worse one. It lasted three days, and in one twenty-four-hour stretch of it I burned through an entire Codex 20x max plan.
