hairyf knitwork-x provides programmatic code generation for JavaScript and TypeScript. It is forked from knitwork and adds comprehensive TypeScript helpers: ESM (import/export), strings, variables, classes, interfaces, functions, types, control flow (if/try/loop/switch), and serialization (object/array/map/set). All gen* functions return strings suitable for splicing into source; they are pure and do not mutate inputs.
Use this skill when an agent needs to generate code strings (e.g. for codegen tools, plugins, or dynamic module output).

Key Points
- Return type: Every
gen*function returns astring(code fragment). - Options: Most accept an optional
optionsobject (e.g.export,singleQuotes,indent); default to{}. - Indent: When supported, pass
indentas the last parameter; useindent + " "for nested blocks. - Strings: Use
genString(input, options)for quoted/escaped output sosingleQuotesis respected. - Composing: Combine
gen*outputs (e.g.genClass(..., [genConstructor(...)])) to build larger snippets.
