Plan Marshall Plugin - CUI JavaScript Domain

Domain manifest skill providing CUI-specific JavaScript project patterns as an additive extension to pm-dev-frontend.

Enforcement

Prohibited actions:

• Do not modify extension.py without updating this manifest documentation
• Do not bypass ExtensionBase inheritance for domain registration
• Do not hardcode skill paths; use bundle notation

Constraints:

• Extension must implement get_skill_domains() from ExtensionBase
• Domain identity must match the bundle name convention (javascript-cui)
• Profile-based skill organization must align with plugin.json registration

Additive Design

This bundle extends pm-dev-frontend — it does not stand alone:

Layer	Provided by	What it gives
Base	pm-dev-frontend	JavaScript domain (javascript), triage, ESLint, JSDoc, Jest testing
Extension	pm-dev-frontend-cui	CUI domain (javascript-cui), Maven integration, project structure defaults

The CUI extension adds the javascript-cui domain on top of the javascript domain. Both are active for CUI JavaScript projects. The applies_to_module() check requires npm + maven (dual build system), signalling a Maven-managed frontend — the defining characteristic of CUI JS modules.

Profile Organization

Core — Always loaded regardless of task:

• cui-javascript-project as a default: project structure and Maven integration are fundamental to every CUI JS task, not optional extras.

Implementation and module_testing — No CUI-specific skills required beyond what the base javascript domain provides.

Quality — No CUI-specific skills at this time.

Rationale for defaults vs optionals: A skill belongs in defaults when skipping it would mean missing critical context for routine tasks. Project structure is always relevant in a CUI JS project; domain-specific utilities (e.g., HTTP patterns) are optionals because they only apply to a subset of tasks.

Extension API

Configuration is in extension.py:

Method	Purpose
get_skill_domains()	Domain metadata with profiles
applies_to_module()	Detect CUI JS via npm + maven dual build system
config_defaults()	Set Maven profile defaults for CUI projects

config_defaults() sets write-once Maven defaults (profile map and skip list) that match CUI Open Source project conventions. These are the same Maven lifecycle hooks CUI Java projects use since the frontend Maven plugin runs inside Maven.

Integration

This extension is discovered by:

• skill-domains get-available - Lists available domains
• skill-domains configure --domains javascript-cui - Configures the domain
• marshall-steward wizard - Domain selection and config_defaults() application
