This paper introduces personalized ambiguity adaptation, a task where coding assistants leverage resolved session history from previous interactions to disambiguate recurring user-specific patterns in new sessions. The authors benchmark existing methods that typically handle ambiguities in isolation, highlighting a gap in cross-session memory utilization. The study evaluates how effectively assistants can identify and resolve these persistent ambiguities without requiring repeated clarification prompts from the user.

• Current coding assistants mostly resolve ambiguity within a single session, ignoring past context.
• New benchmark tests if assistants can recall user-specific ambiguity patterns across sessions.
• Cross-session memory could significantly reduce the need for repetitive clarification prompts.
• Performance metrics provided for adapting to recurring personalized coding ambiguities.

AWS has added an AutoScalingInstanceRefresh update policy to CloudFormation, allowing automatic instance refreshes when properties requiring replacement are updated. This integration enables controlled rollouts with features like launch-before-terminate, alarm monitoring, and bake-time checkpoints. Scaling policies and health checks remain active during deployments, with rollback managed via standard CloudFormation stack operations.

• Define AutoScalingInstanceRefresh as a CloudFormation update policy to automate safe replacements.
• Retain service health during updates as scaling policies and health checks stay active.
• Use bake-time checkpoints and alarm monitoring for controlled, observable rollouts.
• Leverages existing CloudFormation stack rollback mechanisms for failure recovery.

TraceCoder addresses the black-box nature of LLM coding agents by implementing a relational snippet-history schema that logs benchmark references, repair rounds, and LLM explanations for every change. The system utilizes a competitive fractional position-key indexing scheme to assign stable, lexicographic identifiers to code snippets, enabling precise tracking of code evolution. A browser-based visualization tool renders this history as heat-mapped, hover-annotated source code to facilitate post-hoc auditing and explainability.

• Enables full provenance queries by recording benchmark references and failure text per repair event.
• Uses fractional position-key indexing with tree-node delimiters for stable snippet versioning.
• Provides browser-based heat-mapped visualization for intuitive code evolution auditing.
• Transforms ephemeral LLM repair loops into auditable, traceable workflows.

This paper introduces AgenticCANN, a framework for automatically synthesizing Ascend C operators to optimize NPU inference. It addresses the significant challenge of generating code for Huawei's Ascend hardware by incorporating structured, multi-level domain insights to compensate for limited training corpora. The system leverages an agentic evolution approach tailored to the unique programming model of Ascend C, distinct from standard CUDA workflows.

• Automates Ascend C operator synthesis, reducing need for deep hardware expertise.
• Uses knowledge-augmented agentic evolution to handle low-corpus NPU environments.
• Specifically targets Ascend C's unique programming model, unlike prior CUDA-focused LLM tools.
• Delivers structured domain insights across the development lifecycle to overcome platform knowledge deficits.
