The eval discipline that keeps AI products honest

Most AI products in 2026 are shipping without proper evals. The teams that have figured it out are quietly running circles around the ones still relying on "looks good to me." Here is the discipline that actually works.

Cursor, Claude Code, and the ten-times operator
