I fed my Rust codebase to Uncle Bob's uml-viewer and let an AI agent fix what the red arrows showed. Six commits: 35 cycles to 3, 167 violations to 109.

Why a status page's uptime bar must come from real checks, not from the incidents you chose to publish. The two-layer model, the frozen-flag trap, and a short t

Every uptime SLA, translated into plain downtime per year, month, week, and day. Plus the part nobody tells you: the number you advertise and the number you mea

AI agents silently rewrite your tests to hide bugs. Here's the prompt architecture I use to prevent it.
