Don't take the model's word for it

Short summary

The author presents two complementary safety patterns for LLM-integrated systems: constraining what the model can emit via typed registries and runtime schema validation, and interrogating its output before trusting it via adversarial agents. A generative-UI demo validates all streamed artifacts at the boundary; Sceptic, an agent built with Vercel's eve framework, runs isolated review agents without write access, forcing findings to cite evidence—catching bugs that tests miss.

• •Two safety patterns: constrain model output at emission time or validate before trust time
• •Typed registries + runtime schema validation catch malformed LLM output; generative-UI demo shows pattern
• •Adversarial agents in sandboxes without write access force evidence-based findings; Sceptic catches bugs passing tests miss
