I blocklist all of them. I allowlist one going over our issue management system, and a few around internal processes I believe have value (basically very short pointers at OpenAPI specs for making HTTP reqs - could probably be in the repo AGENTS.md but w/e). When opening a new repo I'll look if any skills look like they actually give helpful context and aren't Claude vomiting out a torrent of text (over)fitting some insanely specific use case and allowlist those. Or give up after too much exposure to vile AI created text.
