errore

Run `npx skills add remorses/errore --all -g -y` in your terminal to install the skill globally for your coding agent.

It replaces thrown exceptions with errors returned as values in an Error | T union, so TypeScript forces callers to handle every failure and unhandled errors fail compilation.

It uses plain union types and instanceof checks instead of wrapper types or monads, so there is no unwrapping boilerplate and TypeScript narrows types automatically.

Yes. It ships a SKILL.md file that teaches agents the errors-as-values convention, and it works in Claude Code, Cursor, and other SKILL.md-compatible agents.

No. You convert exceptions to typed errors only at boundaries like fetch or JSON.parse using .catch() or errore.try, then use plain instanceof checks everywhere else.
