Where to place skills to be used in different LLM providers?

[Nikola-Milovic]

It seems that every single IDE/ CLI agent tool is using different place to store skills, is there a centralized place where I can place the skills so they're available to ANY AI system?

Claude uses .claude, codex uses .codex, gemini and cursor something else

each provider tends to define its own convention for storing skills or configs, and at the moment there isn’t a single universal folder that all systems read from. A practical approach is to keep your skills in a neutral directory under version control and then use small sync or symlink scripts to copy/link them into the provider‑specific locations. That way you maintain one source of truth but still satisfy each tool’s expectations. If a standard ever emerges, it’ll likely build on this idea of a shared repo with adapters for each provider
