Can I integrate external tools using MCP or LSP?

Yes, this skill provides specific schemas for .mcp.json and .lsp.json to connect Claude with external servers and language services.

What is the role of hooks in a Claude Code plugin?

Hooks allow you to trigger bash commands, LLM prompts, or other agents during specific lifecycle events like PreToolUse or SessionStart.

What are the required fields for a plugin manifest?

The only strictly required field in the plugin.json file is 'name', which must be a unique kebab-case identifier.

Where should I place component directories like commands and agents?

All component directories (commands, agents, skills, hooks) must be located at the plugin root level, not inside the .claude-plugin folder.

How do I test my plugin locally before publishing?

You can test a plugin locally by running the command 'claude --plugin-dir ./path-to-your-plugin' to load it into your current session.
