Reviewer scorecard
“Visual regression testing catches bugs that unit tests miss. The Storybook publishing and review workflow is seamless.”
“The simplest way to get typed, validated outputs from LLMs. Pydantic integration is natural for Python developers.”
“Expensive at scale but visual testing ROI is real. Catching UI regressions before production saves time and trust.”
“Does one thing perfectly. No over-abstraction, just structured outputs. The anti-LangChain.”
“Design review directly on PRs is game-changing. No more 'does this match the design?' back and forth.”
“Structured outputs are the bridge between LLMs and traditional software. Instructor makes that bridge trivial to build.”
