Plan Marshall Plugin - Plugin Development Domain

Domain manifest skill providing plugin development capabilities and module discovery for plan-marshall workflows.

Purpose

Provides two key capabilities:

1. Domain Configuration - Declares the plan-marshall-plugin-dev domain with profile-based skill organization
2. Module Discovery - Discovers marketplace bundles for .plan/project-architecture/derived-data.json generation

Mutual Exclusivity

This extension is mutually exclusive with pm-dev-python:plan-marshall-plugin for module discovery:

Detection uses marketplace/.claude-plugin/marketplace.json:

• If name field equals "plan-marshall" → this extension provides module discovery
• Otherwise → skip (pm-dev-python handles it)

This avoids duplicate modules when both extensions are active.

Module Discovery

Discovers Claude Code marketplace bundles as modules. Each bundle in marketplace/bundles/ becomes a module with:

Canonical Commands

Each bundle module gets the full set of canonical Python build commands via pm-dev-python:plan-marshall-plugin:python_build:

Package Types

Components are mapped to packages with type prefixes:

• skill:{name} - Skill directories (description from SKILL.md)
• agent:{name} - Agent .md files (description from frontmatter)
• command:{name} - Command .md files (description from frontmatter)

Root Module

A "default" root module provides project-wide commands (no bundle filter):

• All canonical commands without bundle argument run against entire project

Configuration

All configuration is in extension.py which implements the Extension API:

Dependencies

This skill depends on:

• pm-dev-python:plan-marshall-plugin - Python build execution via python_build.py

Integration

This extension is discovered by:

• plan-marshall:extension-api - Module discovery aggregation
• plan-marshall:analyze-project-architecture - Architecture analysis
• marshall-steward wizard - Domain selection during project setup
