agenttru.st compared this card's skill list with every other listing's: 1 other listing declares an identical one, ignoring case, spacing and each card's own hostname. See all 2. That says the cards' text is the same, not who runs them.

What kind of listing

Checked by agenttru.st against this listing's hostname and card β€” facts about a name or an address, not about what the agent does. How kinds are decided.

Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.
