❓ Why is a Recursion Limit Needed?
The Xpert AI platform supports collaboration among multiple agents, enabling multi-turn processing, conditional logic, and context passing. These features may lead to nested invocations, such as:- Agent A delegates part of a task to Agent B, which then delegates to Agent C, and so on
- A failed task triggers a rollback or retry mechanism
- An agent re-invokes itself to optimize inference based on output results
- Excessive token consumption
- Severe response delays
- System instability
✅ Best Practices
- Clarify the Task Flow: Ensure that the task call paths are convergent, not infinite loops.
- Implement Exit Mechanisms: Define stop conditions in agent logic—e.g., max rounds reached, goal achieved, confidence no longer improving.
- Avoid Unnecessary Nesting: Minimize deep call chains. Prefer flat, modular agent designs with clear responsibilities.
- Configure Limits Wisely: In certain modes (e.g., developer mode), recursion limits can be manually increased. Set conservatively.
🔍 How to Troubleshoot recursion_limit Errors
Follow these steps:
1. Check Invocation Logs
- Log into the Xpert AI Console
- Navigate to the agent execution logs
- Locate the faulty task and inspect the message chain
2. Identify Recursion Paths
- Review model capabilities used by the agent
- Check for circular invocation patterns, such as A → B → A → B → …
3. Check Condition Logic
- Verify whether stop conditions like
if completeare functioning - Ensure conditional checks prevent redundant inferences
4. Fix and Test
- Modify the agent prompt or logic to avoid infinite loops
- Monitor task logs to confirm if the recursion limit is still being triggered
5. Temporarily Increase the Limit (Not Recommended for Production)
- In development or testing environments, advanced settings allow you to raise the
recursion_limit - Always monitor logs and revert to a safe value once the issue is resolved
📌 Example Scenarios and Optimization Tips
| Scenario | Issue | Optimization Tip |
|---|---|---|
| Agent keeps rewriting the same response | No stop condition | Set a max rewrite round limit (e.g., 3) |
| Multiple subtasks depend on each other | Circular dependency | Designate one master agent to control task dispatching |
| Retry logic lacks a cap | Infinite retries | Add a max retry counter |
