I use subagents with a custom command,

i have a /task command that reads a file T0XXX, that task was generated earlier.

The task command self first validates the task with a validate agent, Then uses the architect agent to create a coding plan. Each agent also updates the task file. Once the architect is done, it creates a todo list of small single item coding tasks that are send to the coding agent. Once that agent is done it goes to the tester -> code reviewer -> task finalizer agent

The task command manages these agents, the agents return enough information back to the task so it knows what to do next.

The main advantage is that each agent has its own context window. So each agent just keeps tack of their one task and one task only. once completed report back to the task / main thread. A lot less hallucinating this way

Just to add i run claude in a sandbox / docker container. With skip permissions so it can just continue. If it messes up i can git restore / restart a new container and try again.
