The subfolder pattern works in Copilot Cowork, so the design question actually matters. How to structure SKILL.md as a dispatch router, where organisational content belongs, and why the growing community marketplaces are a risk, not a shortcut.
A week after my first Copilot Cowork custom skills post, Microsoft has quietly changed three of the behaviours I documented. The install flow, the Skills panel, and the skill format have all moved. None of it is in Microsoft Learn yet.
I tested Copilot Cowork custom skills for a week. The docs make setup look simple, but there's undocumented behaviour, built-in skill conflicts, and a persistence gap vs Claude Cowork.
