Why is plugin caching important to consider?

Claude Code copies installed plugins to a cache directory, meaning path traversals (../../) will break. This skill helps you structure resources so they remain accessible within the plugin directory.

What is a Claude Code plugin?

A Claude Code plugin is a package that extends Claude's capabilities with custom commands, agents, event hooks, and skills, allowing for domain-specific automation.

How do I validate my plugin before distribution?

The skill provides a validation checklist that includes verifying the plugin.json schema, checking for required README and LICENSE files, and testing commands locally using the /plugin marketplace add command.

What is the benefit of a consolidated marketplace?

Consolidated marketplaces use a single marketplace.json with 'strict: false' to manage multiple plugins in one repository, acting as a single source of truth and preventing version drift.

Can I use external tools like MCP servers in my plugin?

Yes, this skill supports the configuration of Model Context Protocol (MCP) servers within the plugin manifest, allowing your plugin to interact with external data sources and tools.
