A masked key may still need to be revoked.
If a real credential has appeared in a public issue, chat, repository or AI conversation, assume it may be exposed. Revoke or rotate it with the provider. Masking is for preventing the next accidental disclosure.
Clean before you paste
Run logs and error messages through UCLLL first. Review the protected copy, then paste only the information needed to diagnose the problem.
Supported patterns are not a guarantee
Key formats vary. UCLLL recognises several common patterns and long identifiers, but you should add project names, internal IDs and unusual secrets under custom words.
