Why subscribe

Models hate naive assertions. You still need tests hooked at the right spots. Guard what your code promises users so refactors stop feeling like roulette.

For: Engineers shipping AI-backed code who need signal from CI, not green noise.

  • A behavior-first strategy that survives model upgrades
  • Guidance on mocks and seams that do not lie about reality
  • Heuristics to kill flaky tests before they rot morale
  • Patterns for good vs. self-sabotaging tests
  • A quick audit you can run on a Friday afternoon
  • Language for 'what must never break' in agent code
  • Optimizes for outcomes you defend in incident review
