llm-keys-ui 0.1

The release of llm-keys-ui 0.1 introduces a plugin that allows users to manage API keys on remote machines without pasting them into the ChatGPT app. By running a simple command, the plugin provides a local or Tailscale URL for an interface where additional keys can be saved, and later retrieved via a shell command. This streamlines key management for coding agents used in LLM projects.

datasette-auth-github 1.0

The article announces the 1.0 release of the datasette-auth-github plugin. The author discovered that the plugin was setting cookies without a Max‑Age parameter, causing sessions to expire at the end of a browser session, especially on Mobile Safari. This issue was fixed in pull request #80, and the plugin is now stable and tested against Datasette 0.65.x and 1.0ax.

Quoting Thariq Shihipar

The article announces that Claude Code will now support AGENTS.md files starting with version 2.1.277. If a CLAUDE.md file is absent in a folder, Claude will automatically look for and use AGENTS.md, leveraging Claude Code mods to customize the harness. The built‑in mod is available for use, and users can also create their own custom project instructions.

SIMLIFE: Pattern Understanding for Long-Horizon Human-Agent Partnership

SIMLIFE is a scalable platform that simulates long-term household life with rich visual observations, ground-truth action logs, and synthetic dialogues. It introduces the SimLife-BP benchmark, which tests long-context pattern understanding by requiring agents to infer latent behavioral rules from weeks or months of everyday observations across 106 episodes. The benchmark includes 1,439 question-answer pairs that probe direct, counterfactual, noisy, and inverse reasoning under varying rule hints.

MAGS: Multi-agent Auto-formalization Guarantees Safety for Agentic Outputs

The paper introduces MAGS, a multi-agent framework that automatically generates executable programs with formal safety guarantees. MAGS translates LLM-generated code into the verification-aware language Dafny, repairs any safety violations using verifier feedback, and then compiles the verified code back into executable form. Evaluations on 220 diverse examples—including CUDA kernels, terminal scripts, and robotic-arm tasks—show a 100% success rate in producing programs that meet frozen safety specifications, with additional safety and functional tests confirming strong performance across domains.

Closed-World Resolution Against Tool Hallucination in LLM Agents

The paper investigates a new failure mode of tool‑augmented large language model agents: calling non‑existent tools with arguments that do not match any declared schema. It introduces a five‑class taxonomy of tool hallucination, presents a training‑free closed‑world resolver that checks registry membership and signatures, and demonstrates that hallucinations persist across ten hosted models and various invocation surfaces, including the Model Context Protocol. The authors release a Hallucinated‑Tools Benchmark to enable comparison of resolver methods.

Self Improvement via Fast Tree-search

The paper introduces SIFT, a sample‑efficient framework for self‑improvement of coding agents that uses a fast tree‑search guided by an LLM‑as‑a‑judge signal. By performing pairwise comparisons of candidate patches and aggregating results with a regularized Bradley‑Terry model, SIFT limits expensive downstream evaluations to only the most promising nodes. The approach achieves higher coding performance on the Polyglot benchmark while reducing CPU hours, wall‑clock time, and API costs compared to prior tree‑search self‑evolution methods.

Continual Enterprise World Model Discovery in Dynamic Systems

The paper introduces a method for continual enterprise world model discovery, enabling an agent to learn and adapt to business rules in dynamic systems without prior knowledge. Using a ServiceNow environment called EnterpriseWorldShift, the authors evaluate their Continual Discovery Agent (CDA) across four rule-modification scenarios—discovery, revision, extension, and retirement—showing that CDA predicts rule effects more accurately than lookup-based approaches, improving IoU by up to 8.98 points. The agent can answer queries from its internal model without querying the live system.

ScientistTwo: Pioneering the Human Knowledge Frontier with Autonomous AI

The paper introduces ScientistTwo, a fully autonomous multi‑agent framework that takes a scientific problem, establishes baselines, generates hypotheses, and coordinates specialized agents to conduct an end‑to‑end discovery cycle without human intervention. It rigorously tests and refines its methods through automated experiments, ablation studies, and a closed‑loop peer‑review engine. Benchmarking against top conferences (ICLR, ICML, NeurIPS) shows that ScientistTwo produces expert‑level, publishable papers and codebases that outperform human state‑of‑the‑art models and receive higher review ratings under automated AI review.

Neuro-Symbolic Agentic AI for Networked Low-Altitude UAVs

The paper proposes Neuro‑Symbolic Agentic AI (NSAAI) as a framework that blends neural grounding, symbolic reasoning, and closed‑loop interaction to enhance decision‑making for networked low‑altitude UAVs. It outlines NSAAI’s strengths in data efficiency, compositional generalization, continual learning, and zero‑shot transfer, and presents a reference architecture covering task management, planning, verification, skill execution, and network interaction. An urban fire‑inspection simulation demonstrates how a UAV can coordinate sensing, cloud access, and verified image‑delivery skills under intermittent connectivity, illustrating NSAAI’s potential for reusable skills, evidence‑grounded decisions, and adaptive mission execution.
