 META ORCHESTRATOR for implementation workflow: design → test → lint → refactor → review → commit.
 Use for any commit: features, bug fixes, refactors.
 
+## AUTO-ENGAGEMENT (When Invoked by Hook)
+
+If you're reading this because the UserPromptSubmit hook detected Go code work, the detection is already done.
+
+**Simply announce and proceed:**
+
+"Using go-ldd workflow for this Go code work"
+
+Then jump directly to the Pre-Flight Check to gather context and start the workflow.

+
 ## When to Use
 - Implementing any code change that should result in a commit
 - Need automatic workflow management with quality gates
