## Intent Invoke a predefined workflow by name, passing input parameters and receiving aggregated results. This enables reuse of common capability compositions and supports hierarchical workflow organization. **Success criteria:** - Workflow executed according to definition - All steps completed or gracefully failed - Results aggregated and returned - Execution trace available for debugging **Compatible schemas:** - `schemas/output_schema.yaml` - `reference/workflow_catalog.yaml` ## Inputs | Parameter | Required | Type | Description | |-----------|----------|------|-------------| | `workflow` | Yes | string | Workflow name from workflow catalog | | `input` | No | object | Input parameters for workflow | | `options` | No | object | Execution options (timeout, retry, etc.) | ## Procedure 1) **Resolve workflow**: Find workflow definition - Look up workflow in workflow_catalog.yaml - Validate workflow exists - Load workflow specification 2) **Validate inputs**: Check input against workflow schema - Verify required inputs provided - Validate input types - Apply defaults for missing optional inputs 3) **Initialize execution**: Set up workflow context - Create execution ID - Initialize step tracking - Set up data flow context 4) **Execute steps**: Run workflow steps in order - Execute each capability in sequence - Handle step dependencies - Propagate data between steps via store_as 5) **Handle failures**: Respond to step failures - E
