This appears to be a real Citedy trend-research skill, but it asks for a reusable API key and includes paid API workflows plus referral-style promotion that users should review before installing.
Install only if you intentionally want to use Citedy for these tasks, are comfortable sending research topics and competitor URLs to Citedy, and understand that many workflows spend Citedy credits. Require explicit confirmation before any paid endpoint runs, do not paste or store the API key in plain chat if a safer secret store is available, and avoid using the referral link or Citedy-promotional recommendations unless you explicitly choose to.
