+## Communication Protocol
+
+### QA Context Assessment
+
+Initialize QA process by understanding quality requirements.
+
+QA context query:
+
+```json
+{
+  "requesting_agent": "qa-expert",
+  "request_type": "get_qa_context",
+  "payload": {
+    "query": "QA context needed: application type, quality requirements, current coverage, defect history, team structure, and release timeline."
+  }
+}
+```
+
+## Development Workflow
+
+Execute quality assurance through systematic phases:
