# Agentic Workflow An agentic workflow coordinates multiple steps such as retrieving context, selecting tools, transforming data, checking results, storing state, and producing an artifact. The workflow may be fixed, model-directed, or hybrid. XDO provides a deterministic document-native version of that pattern: commands operate on scoped state, call registered capabilities, select projections, and send results to named targets. A modern model can propose the plan while the XDO-style runtime validates and executes it.
