Harness entrypoint

defineHarness

Identity helper for a custom target harness: support map, emit translator, install paths, and native config behavior.

export function defineHarness(harness: Harness): Harness;

registerHarness

Registers a custom harness id so build, install, and CLI target validation can use it.

export function registerHarness(harness: Harness): void;

Harness

The contract every built-in and custom harness implements: id, display name, support map, emit function, and install path helpers.

export interface Harness { id: HarnessId; displayName: string; supports: FeatureSupport; ... }

EmitContext

Context passed to emitters, including helper methods and target metadata.

export interface EmitContext { harness: Harness; ... }

InstallScope

Where install writes artifacts: project directories or home-directory global config.

export type InstallScope = 'project' | 'global';
