# AGENTS.md — TypeScript

- `strict: true` + `noUncheckedIndexedAccess: true` are non-negotiable.
- No `any`. No `enum`. No silent type widening.
- Narrow `unknown` with guards or `zod`.
- Prefer discriminated unions for state. Prefer `satisfies` over `as`.

```bash
pnpm typecheck    # tsc --noEmit
```
