Lightweight Result type for TypeScript with generator-based composition.
better-result is a TypeScript library that represents either a successful value or an expected failure as a typed Result, allowing multi-step workflows to stop when an operation fails. TypeScript developers use it to make recoverable errors explicit while keeping unexpected exceptions as thrown defects. The catalogue skills and instruction support working with the library.
This repository also configures its own agents. See what better-result tells them →

Adopt better-result in an existing TypeScript codebase. Use for a repository-wide error-handling audit and proposal, or for implementing a named vertical slice with TaggedError and Result.

Migrate a TypeScript codebase from better-result 2.x to 3.0. Use when upgrading better-result across the TaggedError syntax, removed Result serialization helpers, recovery inference, matching, or retry APIs.
