Mrrlin and other AI agent tools, compared.
Choosing between an agent tool and an execution workspace starts with where your work breaks down. An agent tool is the thing that writes the code or runs the task, and if one person drives it and reviews the result in the same sitting, that may be all you need. An execution workspace matters when the work outlives the session: several agents share one goal, someone other than the author approves what ships, and the reasons behind a decision have to survive until next month. Mrrlin is built for that second case. It plans a goal into tasks, runs your own agents in isolated worktrees, sends their output to reviewers on other models, and holds sensitive actions for approval. Each comparison below helps you test which case you are in.
