This is designed for when you've already written out an implementation plan and want Claude to execute it methodically with review checkpoints. It breaks work into batches (default is three tasks at a time), reports back after each batch, and waits for your feedback before continuing. The critical bit is the upfront plan review where Claude is supposed to flag concerns before starting rather than improvising mid-execution. It explicitly tells Claude to stop and ask when blocked instead of guessing, which is the right instinct but depends heavily on having a well-structured plan to begin with. Chains into the finishing-a-development-branch skill when tasks are complete. Most useful when you want tight control over implementation pacing.
