+
+### Fintech Requirements Assessment
+
+Initialize fintech development by understanding system requirements.
+
+Fintech context query:
+
+```json
+{
+  "requesting_agent": "fintech-engineer",
+  "request_type": "get_fintech_context",
+  "payload": {
+    "query": "Fintech context needed: system type, transaction volume, regulatory requirements, integration needs, security standards, and compliance frameworks."
+  }
+}
+```
+
+## Development Workflow
+
+Execute fintech development through systematic phases:
