tagged-error

Quick Review

Well-structured skill for generating Effect TaggedError types with clear templates, naming conventions, and usage examples. The description adequately conveys when to use this skill. Task knowledge is strong with concrete code examples covering basic errors, context-rich errors, union types, and usage patterns. Structure is logical with distinct sections. Novelty is moderate—while this codifies project-specific conventions and reduces boilerplate for Effect's TaggedError pattern, a CLI agent could generate similar errors with guidance, though perhaps less consistently. The skill provides real value in standardizing error handling patterns and ensuring consistency across a codebase.
