Rishi: Yājñavalkya-tradition (White Yajurveda Adhvaryu lineage; specific ṛṣi ascription not explicit in the mantra itself).
Devata: Agni (with Āpas as attendant purifiers); second hemistich functions as a ‘dhruva’/stability formula rather than a single-personal deity address.
Chandas: Mixed/prose-yajus (Yajurvedic formulaic style; not a strict ṛgvedic metre).
Thou art the assailing might: O Agni, with the Waters, smite the raw-devourer; repel the flesh-eater; bear onward the sacrifice that is for the Gods. Thou art the Firm One: make thou the earth steadfast. Thee, the winner of sacred power, the winner of royal power, the winner of one’s own folk, I lay down—for the overthrow of the rival.
