Overview Effect-TS provides a type-safe error channel (E in Effect ) that tracks potential failures. Use Tagged Errors for distinguishability and specialized combinators for handling or accumulating errors.

| Define Error | Data.TaggedError | Create distinguishable, typed errors. | | Catch One | Effect.catchTag | Handle a specific tagged error by its tag. | | Catch All | Effect.catchAll | Handle all errors in the channel. | | Accumulate | Effect.all(..., { mode: 'either' }) | Collect multiple results/errors into Either[]. |

Use when implementing error handling, validation logic, or custom error types in Effect-TS. Source: mrevanzak/effect-ts-skills.
