SkillGate Pre-Filters Agent Skills with Rules, Cutting LLM Input by 77% but Still Missing Nearly a Quarter of Attacks

The open-source SkillGate uses 530 rules to identify suspicious snippets before agents load skills, then sends them to an LLM for classification and isolation. Official benchmarks measured a 1.13% false-positive rate and 76.9% recall, showing that a low-cost gateway is feasible but cannot yet replace sandboxing and least privilege.

Shieldstral Encodes Moderation Policies in Queries; 3B Multimodal Model Achieves 84.9% Average F1 on Text Safety Benchmarks

Shieldstral unifies content moderation as a binary question-answering task whose criteria can be specified in natural language, allowing the same model to switch standards based on the product context. The paper reports average F1 scores of 84.9% for text and 83.8% for multimodal content, but the model weights and complete inference package have not yet been released.

Testing 1,723 MCP Applications: Nearly Two-Thirds Did Not Require Approval Before Tool Execution

The first large-scale study of MCP clients found that official SDKs and file-based configuration have become mainstream, but only 37.2% of applications require blocking approval. The protocol has standardized communication formats, but permissions, configuration, and human oversight have yet to converge into consistent application-layer practices.

HANDBOOK.md Governs Agents With Hundred-Page Corporate Rulebooks; Best Strict Pass Rate Across 30 Model Configurations Is Just 36.2%

Surge AI has released 65 long-horizon agent tasks requiring models to follow changing policies spanning 20 to 124 pages while working across email, chat, calendars, and enterprise tools. The best configuration passed only 36.2% of tasks under strict scoring, which requires every rule to be satisfied simultaneously—showing that a large context window does not guarantee sustained compliance.

PatientAgentBench Tests Medical Agents Across 1,200 Tool-Use Dialogues, Yet the Best Model’s Triage Pass Rate Is Still Only 88%

Amazon Science has released PatientAgentBench, which tasks medical agents with completing multi-turn primary care workflows using synthetic medical records and stateful tools. The largest performance gap among the ten models appears in triage decisions, showing that answering medical questions correctly is not enough to prove that an agent can execute workflows safely.

Layer-Specific LoRA Experiments Show That the Best Update Location Differs for Learning Vocabulary, Facts, and Behavioral Policies

A new study restricted LoRA to the early, middle, or late blocks of Transformers and found that different learning objectives exhibit reproducible “adaptation geometries.” The findings elevate adapter placement from an implementation detail to a design variable for controlling knowledge transfer and side effects.

Asking for JSON Makes 44 Models’ Answers Converge, Suggesting Structured Output May Alter Model Judgment

An experiment spanning 44 language models found that merely adding “respond in JSON” reduced answer diversity, without schema enforcement or constrained decoding. The findings remind developers that structured output is not just a serialization layer—it may also change the answers models actually choose.

GitHub Models to Shut Down Completely on July 30, Disabling Inference APIs and BYOK Endpoints

GitHub Models will discontinue all services on July 30. Existing customers will lose access to the model catalog, Playground, inference APIs, and BYOK endpoints. Migrating to Microsoft Foundry is not simply a matter of changing URLs: teams must also revalidate identity and access, model versions, billing, and output compatibility.

NInfer Hard-Codes Inference Paths for Two Qwen3.6 Models, Reaching 543 Tokens per Second in Long-Context Decoding on a Single RTX 5090

The open-source NInfer uses custom quantization, weight layouts, fused kernels, and an MTP draft path to sustain long-context decoding at about 543 tokens per second for Qwen3.6-35B-A3B on a single RTX 5090. Its speed comes from deep specialization for the model and GPU, but it currently supports only two checkpoints, lacks continuous batching, and has yet to be independently benchmarked under identical conditions.

MLPerf Endpoints 0.7 Moves Cloud Inference to Continuous Submissions, but Initial Release Still Lacks Cost Normalization

MLCommons has launched Endpoints 0.7 for managed inference services, replacing twice-yearly static comparisons with automated submissions, continuous review, and interactive charts. The initial release covers five providers and three benchmarks, but cost normalization, agentic workloads, and broader participation will not arrive until version 1.0.

SpecBox 在模型生成期間預熱代理沙箱，P99 延遲最高縮短至三分之一

SpecBox 根據串流 token 推測即將使用的工具，讓沙箱啟動與模型推論重疊，並以相依圖預取後續執行環境。論文報告其 P99 端到端延遲最高改善 2.9 倍、峰值記憶體降低 45.9%，但目前仍是研究原型，尚無公開程式碼或獨立重現結果。

CoTinyVLA Outperforms 7B Robotics Baselines With Just 0.9B Parameters, but Testing Remains Limited to Simulation

CoTinyVLA distills hierarchical reasoning from a 35B teacher into a 0.9B vision-language-action model, outperforming the strongest 7B baseline across all four LIBERO-Plus test suites. Its code, training pipeline, and weights are public, but there are still no results from real robots, different hardware, or independent reproductions.
