+# Route Stickiness
+
+> `agent_framework_oci` feature — English guide.
+
+**Main implementation:** `routing/enterprise_router.py + runtime/agent_runtime.py`
+
+---
+
+### 1. What it is
+
+Prevents short follow-up messages from unnecessarily switching the conversation to another agent.
+
+### 2. Problem it solves
+
+Production agents should not rely on prompts alone to “do the right thing”. This feature moves a specific responsibility into a controlled framework layer, reducing unpredictable behavior and duplicate domain-agent code.
+
+### 3. Simplified flow
+
+```text
+current message
+ + short history
+ + previous route
+   ↓
+semantic continuity
+   ↓
+keep route or handoff
+```
+
+### 4. How it works internally
+
+Route Stickiness evaluates whether a new message is semantically continuous with the current subject/agent. It reduces agent ping-pong for messages such as “what about that amount?”, “yes”, “the second one”, or “and last month?”.
+
+Existing settings include `ENABLE_ROUTE_STICKINESS`, `ROUTE_STICKINESS_LLM_PROFILE`, `ROUTE_STICKINESS_CONFIDENCE_THRESHOLD`, `ROUTE_STICKINESS_HISTORY_TURNS`, and `ROUTE_STICKINESS_MAX_TOKENS`. The decision may still allow handoff when there is enough evidence of a topic change.
+
+### 5. How to enable/configure
+
+Exact activation depends on the template/agent. Check framework settings, YAML configuration, and the service template. Not every feature requires a global flag: some are activated by the contract returned from a tool/workflow.
+
+### 6. Example
+
+```env
+ENABLE_ROUTE_STICKINESS=true
+ROUTE_STICKINESS_CONFIDENCE_THRESHOLD=0.90
+ROUTE_STICKINESS_HISTORY_TURNS=2
+ROUTE_STICKINESS_MAX_TOKENS=80
+```
+
+### 7. Telemetry and observability
+
+When the feature participates in an agent execution, preserve `request_id`, `trace_id`, `session_id`, `agent_id`, `message_id`, and other correlation keys in state/events. This makes the decision observable through Langfuse/Observer without embedding observability logic in the domain.
+
+### 8. How to test
+
+1. Add a unit test for the core behavior.
+2. Add a runtime integration test when state spans multiple turns.
+3. Test the happy path and at least one failure/rejection path.
+4. Confirm retries/replays do not duplicate side effects for transactional features.
+5. In production, also validate telemetry and ID correlation.
+
+### 9. Common mistakes
+
+- A threshold that is too low may trap the user on the wrong agent.
+- A threshold that is too high may lose continuity on short follow-ups.
+- Stickiness should not block explicit handoff when the user clearly changes intent.
+
+### 10. Relationship with other features
+
+Use this feature together with the framework's horizontal capabilities rather than creating a parallel implementation in domain-agent code. For transactional journeys, pay special attention to **Clarification**, **Pause/Resume**, **Durable Idempotency**, **Workflow Error Recovery**, and **Guardrails**.
