+## Error Handling
+
+When the Router cannot determine an appropriate route for the given context, it will route to the **error path** instead of arbitrarily selecting a route. This happens when:
+
+- The context doesn't clearly match any of the defined route descriptions
+- The AI determines that none of the available routes are appropriate
+
 ## Best Practices
 
 - **Write clear route descriptions**: Each route description should clearly explain when that route should be selected. Be specific about the criteria.
 - **Make routes mutually exclusive**: When possible, ensure route descriptions don't overlap to prevent ambiguous routing decisions.
-- **Include an error/fallback route**: Add a catch-all route for unexpected inputs that don't match other routes.
+- **Connect an error path**: Handle cases where no route matches by connecting an error handler for graceful fallback behavior.
 - **Use descriptive route titles**: Route titles appear in the workflow canvas, so make them meaningful for readability.
 - **Test with diverse inputs**: Ensure the Router handles various input types, edge cases, and unexpected content.
 - **Monitor routing performance**: Review routing decisions regularly and refine route descriptions based on actual usage patterns.

-Context to analyze:
+Context to route:
 ${context}
 
-Instructions:
-1. Carefully analyze the context against each route's description
-2. Select the route that best matches the context's intent and requirements
-3. Consider the semantic meaning, not just keyword matching
-4. If multiple routes could match, choose the most specific one
+ROUTING RULES:
+1. ALWAYS prefer selecting a route over NO_MATCH
+2. Pick the route whose description BEST matches the context, even if it's not a perfect match
+3. If the context is even partially related to a route's description, select that route
+4. ONLY output NO_MATCH if the context is completely unrelated to ALL route descriptions
 
-Response Format:
-Return ONLY the route ID as a single string, no punctuation, no explanation.
-Example: "route-abc123"
+OUTPUT FORMAT:
+- Output EXACTLY one route ID (copied exactly as shown above) OR "NO_MATCH"
+- No explanation, no punctuation, no additional text
+- Just the route ID or NO_MATCH
 
-Remember: Your response must be ONLY the route ID - no additional text, formatting, or explanation.`
