When to Use

Use this skill when:

• You need a type-safe, composable unit conversion graph for a domain. The primary entry point for all unacy usage. → use createRegistry
• You already have a Zod schema for a format and want to produce a typed Parser with minimal boilerplate. → use createParserWithSchema
• You are receiving a runtime value and need to confirm it is a valid TypeScript enum before using it as a TypedMetadata<EnumType>.type field. → use validateEnum
• You need to dynamically dispatch on the kind of a metadata object at runtime (e.g., in serialisers or schema generators built on top of unacy). → use detectMetadataKind

Do NOT use when:

• You only need a single direct conversion with no type guarantees — a plain function is lighter and requires no registry setup overhead. (createRegistry)
• Your validation logic cannot be expressed as a Zod schema — write a custom Parser<T> instead, throwing ParseError on failure. (createParserWithSchema)

API surface: 11 functions, 5 classes, 24 types

Configuration

3 configuration interfaces — see references/config.md for details.

Quick Reference

Key functions: createRegistry (Create a new, empty converter registry), createParserWithSchema (Create a Parser<WithFormat<T, F>> backed by a Zod-compatible schema), validateEnum (Validate that a runtime value is a valid TypeScript enum object), validateClass (Validate that a runtime value is a valid class constructor), validateRecordSchema (Validate that a runtime value is a valid record schema), validateTupleSchema (Validate that a runtime value is a valid tuple schema), isEnumMetadata (Type guard: returns true when meta), isClassMetadata(Type guard: returnstruewhenmeta), isRecordMetadata (Type guard: returns true when meta), isTupleMetadata(Type guard: returnstruewhenmeta), detectMetadataKind (Detect the kind of a metadata object by inspecting its type field) Key classes: UnacyError (Base error class for all unacy errors), CycleError (Error thrown when a cycle is detected during BFS path-finding), MaxDepthError (Error thrown when BFS path-finding exceeds the maximum conversion depth), ConversionError (Error thrown when a conversion cannot be performed), ParseError (Error thrown when parsing a string into a format-tagged value fails)

40 exports total — see references/ for full API.

References

Load these on demand — do NOT read all at once:

• When calling any function → read references/functions.md for full signatures, parameters, and return types
• When using a class → read references/classes.md for properties, methods, and inheritance
• When defining typed variables or function parameters → read references/types.md
• When configuring options → read references/config.md for all settings and defaults
