DESCRIPTION:Life sciences compliance isn't forgiving. When your software he
 lps companies navigate FDA regulations\, ISO 13485\, and EU MDR\, "move fa
 st and break things" isn't an option. Audit trails matter. Documentation i
 s mandatory. Getting it wrong means regulatory findings\, delayed product 
 launches\, or worse — patient safety risks.\n\nDuring the development of
  our AI Assistant we made every mistake in the most unforgiving environmen
 t possible. After more than a year building with PydanticAI\, pydantic-eva
 ls\, and Claude — nearly 3\,000 commits and 20+ contributors — here ar
 e 7 anti-lessons so you don't have to repeat them:\n\n1. **"We need a mult
 i-agent system"** — We built one. Then deleted it.\n2. **"Agents need so
 phisticated planning"** — A todo list beat our workflow engine.\n3. **"G
 ive the agent lots of specific tools"** — Two high-level tools replaced 
 dozens.\n4. **"Encode workflows in code"** — Markdown files the agent re
 ads at runtime won.\n5. **"It works when I test it"** — Simple tests ≠
  real user journeys. Realistic evals or you're blind.\n6. **"Automate ever
 ything"** — Human stays in the driver's seat\, not the trunk.\n7. **"App
 ly what made you successful before"** — Your engineering instincts might
  hurt you here.\n\nReal code\, real git commits\, real mistakes from a dom
 ain where mistakes are expensive.\n\n**Come for the mistakes. Leave with s
 hortcuts.**
