Can I use this to create plugins for other users?

Yes, it includes specific guidance on plugin packaging patterns and the .claude-plugin/plugin.json structure for distribution.

Does this skill help with testing AI behaviors?

Yes, it includes an evaluation strategy that helps you define 20-50 test cases to validate the reliability and accuracy of your extension.

What is the purpose of the decision framework?

The decision framework prevents over-engineering by matching task complexity to the simplest possible component type that meets your requirements.

How do I choose between a skill and a sub-agent?

This skill uses a 0-10 scoring framework. Simple deterministic tasks (1-6) should use skills, while tasks requiring model-driven decisions and flexibility (7-8) are better suited for sub-agents.

Productivity & Workflow

Guides developers in selecting and implementing the optimal Claude extension architecture using a complexity-based decision framework.

This skill acts as a strategic orchestrator for extending Claude's capabilities, helping developers navigate the choice between hooks, agent skills, sub-agents, and full agent teams. By applying a 0-10 complexity scoring matrix, it ensures that implementations remain as simple as possible while meeting project requirements. It provides a standardized workflow for the entire extension lifecycle—from design and complexity assessment to the creation of evaluation test cases and final verification—making it an essential tool for building robust, scalable AI-driven automation.
