aapersh/strategy-skills-for-claude ? reverse-engineered prompt

Build me a clean repository of 21 Claude skills for strategy work, grouped into six practical consulting areas like diagnosis, market intelligence, strategic choice, execution, governance, and executive communication.

I want each skill to be a small standalone markdown workflow that I can upload into Claude as a SKILL.md file, with clear guidance on when to use it, what it should produce, and the kind of consulting style it should follow. Keep the tone sharp, structured, and executive friendly, like a top tier strategy consultant would work. Make the skills useful for real business problems such as framing the issue, mapping markets, testing assumptions, building a business case, prioritizing initiatives, stress testing risk, and writing decision memos.

Please organize the folder structure neatly, add a strong README that explains the purpose of the collection and how to use each skill, and make sure the content feels consistent across all 21 files. If you need to check current Claude skill formatting or best practices, look up the latest docs online first.
