Rigveda 1.1 opens with a direct address, "I magnify Agni, the household priest, the divine ministrant of the sacrifice, the invoker, the bestower of most treasure," and every verse that follows develops the same basic claim, that Agni's distinctive role among the Vedic gods is to serve as the ritual's own internal priest, the fire that receives the poured oblation and physically carries it, as smoke rising to the sky, toward the other gods the sacrifice is meant to reach. This is praise built around a functional description rather than around abstract attributes: the hymn does not dwell on Agni's appearance or cosmic origins so much as on what Agni does at the exact moment of sacrifice, bringing the gods to the offering and the offering to the gods, uniting the human and divine sides of the ritual in his own single body as flame.
The hymn closes by asking that the wealth and prosperity that come easily to a father coming to his son come as readily to the one who worships Agni in this way, a general wish for ritual efficacy attached to the act of correct praise rather than a specific request for a favour, which is what places the hymn, in its liturgical use as an opening invocation for the fire offering, among texts of praise rather than among the offering-petition prayers catalogued elsewhere in this corpus.
