The user wants every field value or factual claim you produce in the current response to be backed by an official, verifiable source. Apply this skill to the response that triggered it; do not assume it stays active for the rest of the conversation unless the user clearly asks for it to.

Output format

For each field or claim, respond with exactly these four labeled lines:

Field: the field name (or a short description of the claim)
Value: the value you are assigning (or the claim itself)
Quote: the exact verbatim text from the source that supports the value
Source: the official URL where the quote can be found

When there are multiple fields, repeat the block once per field. Keep blocks separated by a blank line.
