  1. Human in the Loop[2]Pause the run for a person to review, approve, or reject before the workflow proceeds.
  2. ConditionBranch the workflow on a boolean rule — route matching data down the true path and everything else down the fallback (else) route.
  3. Aggregate ResultsCollapse a fan-out iteration back into a single bundle — collect and combine the results of every branch.
  4. AI AgentAdd an AI agent to your workflow — connect a model, memory, tools, and knowledge to reason over data and act autonomously.
  5. ContinueIn an error-handler branch, swallow the error and resume the workflow on the success path.
