TypeScript Strict Rule
Keeps the agent honest about types — no `any`, no non-null assertions to silence errors, and explicit return types on exported functions.

Snippet

description: TypeScript strictness conventions
alwaysApply: true
---
- Never use `any` — prefer `unknown` and narrow it
- Do not use `!` non-null assertions to silence the type checker
- Add explicit return types to exported functions
- Model invalid states out of existence with discriminated unions
- Validate external data at the boundary with a schema (zod)
