An agent avatar pack is a folder of still images in one visual style. You assign those images to the agents already in your roster: a chief of staff, an engineer, a designer, a marketer, an assistant. The pack does not add a new agent and it does not replace the tool you use to run them.
CoolAgents packs are built for that job. Each pack is one style, about twenty faces, so the crew looks related instead of like twelve unrelated portraits.
Why a pack, not a single portrait
A single portrait dresses one bot. A pack dresses the roster. When every role shares a style, the sidebar reads as one crew. When every role is a different generator result, it reads as a pile of pictures.
The homepage preview shows the same style on each role before you buy. That is the decision: pick the crew, not a one-off face.
