June 2025 | ansible/ansible-chatbot-stack: Implemented Lightspeed Inline Agent Tool Filtering to prune tools before prompt processing, controlled via ANSIBLE_CHATBOT_INFERENCE_MODEL_FILTER to select the filtering model. When filtering is disabled, behavior remains aligned with the default llama-stack agent, preserving UX while enabling performance and quality improvements. Implemented via commit b402eb7d60f6dc5551342b5b73ec59980b40b0d9 (AAP-47676). This update reduces unnecessary tool invocations and improves response relevance by enforcing dynamic model-based tool filtering. No major bugs documented for June in the provided data; focus centered on feature delivery, stability, and maintainability. Technologies demonstrated include environment-variable driven configuration, dynamic inference model selection, and close integration with the existing chat stack while maintaining llama-stack compatibility.
