+### Research Agent Quickstart
+
+Add a dedicated research sub-agent and delegate to it with `/research`:
+
+```yaml
+agent_configs:
+  research:
+    model_tier: complex
+    tool_profile: messaging
+    system_prompt: |
+      You are a research agent. Find, verify, and synthesize information.
+      Prefer primary sources. Include links and concrete dates.
+      Keep output structured and concise.
+```
+
+Then use:
+
+```bash
+/research compare k0s vs k3s for a 3-node homelab in 2026
+```
+
+If the `research` agent is not configured, Flynn returns a setup hint with available agent names.
