Agent Roles
Every built-in agent role in Cerevisor, what it's for, its smart defaults, and when to use which.
Cerevisor ships with 17 built-in roles . A role is mostly a starting point ; it sets a few smart defaults (which subagent type to use, which model to prefer, which tag color the badge has), then you write the instructions that turn the role into a specific agent for your specific workflow. You can also pick Custom and define everything from scratch, or create your own reusable agents via Settings → Agents → Custom Agents.
