What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of www.trmainz.de controls every word below.

agenttru.st compared this card's skill list with every other listing's: 1,433 other listings declare an identical one, ignoring case, spacing and each card's own hostname. See all 1,434. That says the cards' text is the same, not who runs them.
