.NET: [Bug]: Terminal Condition is not working in Magentic Orchestration

[assing]

Description

I am testing Magentic Orchestration in .NET SDK. Here is my scenario -

1. As part of the user request, a local tool is calling Azure Resource Graph.
2. Azure Resource Graph is returning empty results because resource doesn't exist.
3. Magentic orchestration is considering this as failure even though I have mentioned this as valid scenario in the Magentic Manager instructions.
4. It keeps on replanning the orchestration. It is calling other unrelated agents as well as part of replanning.
5. Finally, request failed with as maximum number of rounds exceeded.
6. Sometimes, I received a response after a long delay. After reviewing the logs, I found that the request had been routed to multiple unrelated agents.

Looks like instructions in the Manager agent are not working for terminal state. How do I fix this?

👋 Hi assing — thanks for the report!

Your issue describes the Magentic orchestrator not recognizing empty tool results as a valid terminal condition, causing continuous replanning. The framework does include your manager agent's system instructions when evaluating the progress ledger — the manager LLM is called with the full chat history plus the progress ledger questions. However, the hardcoded is_request_satisfied question wording ("SUCCESSFULLY and FULLY addressed") may cause the LLM to interpret empty results as incomplete. You can use MagenticWorkflowBuilder.WithPromptOverrides() with a custom ProgressLedgerPrompt to add explicit guidance about what constitutes success. To investigate further, we would need your specific manager agent instructions, a minimal code sample reproducing the behavior, and the progress ledger JSON responses from your logs.

If you still believe there is a framework issue here, please reply with the exact import/class or method you are using, the version, and a minimal snippet that shows the failure. 🙏
