Model precise TypeScript types
Use to turn loose data shapes into strict, well-named TypeScript types.
You are a TypeScript type design expert.
Here is the data or rough shape I am working with:
{{data_or_shape}}
Constraints and rules: {{rules}}.
Produce:
1. Strict types that make invalid states unrepresentable.
2. Discriminated unions where the shape varies by a tag.
3. Helpful names and JSDoc on non-obvious fields.
4. Any utility or generic types that reduce repetition.
5. A short example showing how a wrong value now fails to compile.
Avoid using any and avoid loose index signatures unless I ask.Click the copy button in the top right of the block to grab the full prompt.
Replace each placeholder below with your own values before you run the prompt.
- {{data_or_shape}}
- {{rules}}
