Plugin creation starts with defining your manifest, which specifies commands, parameters, and entry points. Build your TypeScript/JavaScript implementation following Claude Code architecture patterns, then test locally before installation. The skill guides you through architectural decisions, manifest configuration, and code structure to produce a complete, deployable plugin.

Best practices include following TypeScript/JavaScript coding standards, implementing comprehensive testing methodologies, enforcing security checks, and maintaining clear documentation. These practices span manifest design, command implementation, error handling, and debugging strategies to ensure reliable, maintainable plugins across multiple environments and workflows.

Troubleshooting involves identifying common installation errors, examining plugin logs, and applying recovery patterns specific to your environment. The skill provides debugging strategies for permission problems, environment setup failures, and manifest misconfigurations to resolve issues systematically.

Yes, Claude Code plugins support deployment across multiple environments with proper configuration handling. The skill covers environment-specific setup, permission considerations, and deployment patterns to ensure plugins function correctly in development, testing, and production contexts.

Testing methodologies include unit testing individual commands, integration testing plugin interactions, and end-to-end validation. The skill guides you through setting up test frameworks, writing test cases for TypeScript/JavaScript implementations, and validating plugin behavior before deployment.
