I've found an agent to manage agents, plus aggressively creating skills/workflows helps.

The main agent is the entry point:

"review this PR" should open a new workspace and spin up one or more agents to do whatever review workflow you like.

"Implement ticket xyz" should open a new space, read the ticket content, plan/write/test/review/create a PR without much managerial input. You'll still need to answer questions and check work between steps, but all of the busy work can be done by your agent(s) with skills. If they get it wrong, update the skill.

Same for "research this bug report/product question/error trace".
