Why it matters
Making content involves a lot of production steps around the creative part. Here an agent takes on some of those steps so the person can focus on the idea. It is one of 70 sightings filed under Media & Content on Agent Sightings (number 38 by interest), and one of 255 involving Claude Code.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into Claude Code or any similar agent and adjust the details to your situation.
For every audio file in this folder, convert to 44.1 kHz WAV, rename consistently, and produce an English transcript for any Portuguese file. Report what you changed.
Tip: Start small: run it once on a low-stakes example, read what the agent did, and only then let it run on real work.
