Rishi: Traditionally connected with cosmogonic seers; in later ritual indexing often treated as belonging to the Viśvakarman hymn-complex (ṛṣi attribution varies by ancillary tradition).
Devata: Viśvakarman (with Vācaspati as invoked power of speech).
Chandas: Triṣṭubh (by general metrical profile of the Viśvakarman hymn; exact scansion may vary by pada).

Translation
To Vācaspati, to Viśvakarman, for succour—swift as thought—this day, in the winning of the prize, would we make invocation. May he, the all-auspicious, the good artificer, accept with favour all our invocations, for our protection.
