SkillSync: Collaborative Prompt & LLM Skill Registry for Cross-Functional Teams

Show HN: Sx 2.0 – Share AI skills with your team through a Dropbox folder

I can't think of anything worse than sharing skills via Dropbox. The version management and AIBoM problems that generates is extremely painful. There's no way to track which version LLM is being used or match it against the skill, and people will likely load up too many skills. You don't have to expose git repos to end users to use git, or some other database, to provision skills.

We've adopted a simple/similar Dropbox-based approach for skills and rules - each person's ~/.claude/skills is actually symlinked to a folder just for them inside a shared Dropbox folder, one that others on our (small) team can see and edit as well. This solves a set of problems around people writing skills that reference artifacts or other skills that only exist on their system, and/or that reference their own name/information as the creator, and not knowing to make them self-contained and replicable. Luckily, adapting your colleagues' skills to self-contained versions and pulling them into your folder is trivial to instruct an agent to do. And you can have meta-skills that do this on the fly if a colleague has a skill that would unblock your project! (Editing to add a tip: make sure all the folders are set to offline visibility in Dropbox, rather than being loaded on demand from online.) The courtesy simply has to be that you don't write into other people's skill folders unless/until they ask you to maintain something for them - at which point the words "I am assuming direct control" are said with all the necessary gravity and effect. It's great to see someone putting UI and guardrails around this pattern!
