🥇 Remember, Don't Re-read: Stateful ReAct Agents for Token-Efficient Autonomous Experimentation · prio 13

For AI builders creating multi-step agents, this paper demonstrates a practical, architectural method to drastically reduce token costs by transitioning from stateless context re-generation to persistent state management. This shift is critical for building sustainable, autonomous agentic workflows that scale beyond simple, short-lived tasks. arxiv.org · 5 sources · Agents Agent Memory Context Engineering arXiv

🥈 PrologMCP: A Standardized Prolog Tool Interface for LLM Agents · prio 12

Delegating complex deductive reasoning to symbolic solvers like Prolog via a standardized protocol (MCP) offers a more robust and efficient alternative to costly extended chain-of-thought reasoning in LLM agents. arxiv.org · 13 sources · MCP Agents Tool Use Anthropic OpenAI Claude Sonnet 4.6 GPT-4.1 o4-mini

🥉 Attributing Drift in LLM Evaluation Pipelines: System vs. Judge · prio 12

This research provides a crucial methodology for distinguishing between system degradation and LLM judge volatility in production monitoring, directly addressing a major bottleneck in reliable AI deployment. arxiv.org · LLM Evals

4️⃣ Dr-DCI: Scaling Direct Corpus Interaction via Dynamic Workspace Expansion · prio 12

This paper provides a practical approach to scaling agentic systems by bridging the gap between large-scale retrieval and precise local document operations, directly addressing performance bottlenecks in agent-driven data analysis. arxiv.org · RAG Agents Agent Memory Context Engineering Reranking ColBERT

5️⃣ LLM Judges Have Dark Current: A Psychometric Datasheet for LLM-as-a-Judge Evaluation · prio 12

As the builder community increasingly relies on LLM-as-a-judge for automated evaluation, this metrological framework provides essential tools to detect hidden biases and quantify judge reliability, which is critical for making informed model selection and fine-tuning decisions. arxiv.org · LLM Evals Llama-3.1-8B Qwen2.5-14B Qwen2.5 32B
