+# Deep-Dive Documentation Sub-Workflow
+
+**Goal:** Exhaustive deep-dive documentation of specific project areas.
+

+
+## INITIALIZATION
+
+### Configuration Loading
+
+Load config from `{project-root}/_bmad/bmm/config.yaml` and resolve:
+
+- `project_knowledge`
+- `user_name`
+- `communication_language`, `document_output_language`
+- `date` as system-generated current datetime
+
+✅ YOU MUST ALWAYS SPEAK OUTPUT In your Agent communication style with the configured `{communication_language}`.
+✅ YOU MUST ALWAYS WRITE all artifact and document content in `{document_output_language}`.
+
+### Runtime Inputs
+
+- `workflow_mode` = `deep_dive`
+- `scan_level` = `exhaustive`
+- `autonomous` = `false` (requires user input to select target area)
+

+
+## EXECUTION
+
+Read fully and follow: `./deep-dive-instructions.md`
