Output

Output Skill

This skill instructs agents on importing and using the code Kubb generates from an OpenAPI/Swagger spec.

When to Use

• Writing application code that calls the generated client or hooks
• Writing tests that use the generated mocks or schemas
• Wiring generated files into an app

What It Does

• Explains where generated code lands
• Shows how to discover the real exports and a plugin's options
• Lists the rules for keeping generated code in sync

Where output lands

Kubb writes generated code under the output.path from kubb.config.ts (for example ./src/gen), organized into the folders each plugin sets through its own output.path (for example models, clients, hooks). Generated files carry a Do not edit manually banner and are rewritten on every kubb generate, so change them by editing the spec or config and regenerating.

Export names derive from the spec's operationId and schema names. Casing and grouping are configurable, so read the generated files for the exact names and signatures rather than assuming them.

Find what was generated

Inspect the real output instead of guessing:

1. Read kubb.config.ts for the top-level output.path and each plugin's output.path.
2. List the output directory for the actual file and export names.
3. Read an installed plugin's Options type (node_modules/@kubb/plugin-<name>/src/types.ts or the published type declarations) for its options and defaults, and the plugin's docs page (https://kubb.dev/plugins/plugin-<name>) for dependencies. Use those as the source of truth rather than assuming an option name.

Import from a folder's index.ts when output.barrel is set, otherwise import the file directly.

Rules

• Never edit files under output.path. Edit the spec or config and rerun kubb generate.
• Import generated code instead of copying it, so a regenerate keeps callers in sync.
• Configure the runtime client once. The client functions and framework hooks share it.
• Typecheck after regenerating so a spec change that broke a call site shows up.
