This is meta tooling for Claude itself: it chains together multiple skills from the marketplace catalog into sequential workflows with automatic handoffs between steps. You describe a complex multi-step process, and it maps that to a sequence of existing skills where output from one becomes input for the next. It supports conditional logic for branching paths and handles all 81 catalog skills as building blocks. Most useful when you have a repetitive process that touches multiple domains, like "analyze this data, generate a report, then create social posts about the findings." The orchestration layer saves you from manually copying outputs between different skills, though you're essentially programming workflows in natural language rather than getting work done directly.
