marketplace-based skill discovery and registration
Provides a centralized skill registry via .claude-plugin/marketplace.json that maps 27+ Claude Skills across five categories (business-marketing, development, document-processing, productivity, research-analysis). The manifest acts as a single source of truth, defining skill metadata (name, description, source path, category) that enables unified discovery across Claude.ai, Claude Code, and Claude API platforms without requiring separate registration per platform.
Unique: Uses a declarative JSON manifest (.claude-plugin/marketplace.json) as the single source of truth for skill registration, enabling platform-agnostic discovery that works identically across Claude.ai, Claude Code, and Claude API without requiring separate registration mechanisms per platform. The flat directory structure with root-level skill folders creates a transparent, git-friendly skill catalog.
vs alternatives: More transparent and git-native than proprietary plugin marketplaces (e.g., OpenAI's plugin store) because the entire skill catalog and implementations are version-controlled in a single repository, enabling community contributions and offline access.
cross-platform skill deployment and portability
Enables a single skill implementation to be deployed identically across Claude.ai (UI-based), Claude Code (file system at ~/.config/claude-code/skills/), and Claude API (programmatic via skills parameter). Each skill is defined as a portable directory containing SKILL.md documentation and implementation files, with the marketplace manifest mapping logical skill names to physical file system paths. The deployment abstraction decouples skill definition from platform-specific installation mechanics.
Unique: Achieves platform portability through a declarative skill structure (SKILL.md + implementation files) combined with platform-agnostic marketplace metadata, rather than requiring platform-specific adapters or SDKs. The marketplace manifest acts as a routing layer that maps logical skill names to physical implementations, enabling the same skill code to be deployed via different mechanisms (UI upload, file system, API parameter) without modification.
