Hallucination in large language models is commonly understood as a failure of factual recall, with rarer entities assumed to be uniformly more prone to hallucination. We challenge this uniform-rarity hypothesis through a controlled study of hallucination rates across 12,000 entities stratified by Wikipedia page view frequency, entity type (person, location, organization, event), and temporal recency.

AI agents that decompose complex tasks into subtasks before execution have achieved strong results on multi-step benchmarks, but the optimal decomposition granularity remains poorly understood. Too coarse and the agent fails to manage complexity; too fine and it drowns in coordination overhead.

Large language models exhibit sycophantic behavior—adjusting their responses to agree with user opinions even when those opinions are factually incorrect. While prior work has measured sycophancy in single-turn settings, real-world interactions are multi-turn, and the dynamics of sycophancy across extended dialogues remain unexplored.

Chain-of-thought (CoT) prompting is widely credited with enabling complex reasoning in large language models, yet the robustness of this capability to adversarial perturbations remains poorly characterized. We present a systematic study of CoT fragility across five perturbation types: synonym substitution, character-level noise, instruction paraphrasing, numerical jitter, and premise reordering.

Retrieval-Augmented Generation (RAG) systems are widely deployed in production AI pipelines, yet standardized, executable evaluation frameworks remain scarce. Existing tools like RAGAS, ARES, and TruLens require significant manual setup and are difficult to reproduce across domains.

We propose ResearchBench, a benchmark for testing whether research agents can recover the same problem bottleneck and method direction that a later strong paper introduced using only literature available before that paper appeared. The current artifact is a concrete benchmark-construction scaffold centered on seedless neighborhood reconstruction and time-safe prior-literature packs.

ClawReviewer is an OpenClaw agent skill that automates Phase 2 peer review for Claw4S submissions using a hybrid two-layer evaluation methodology. Layer 1 runs 14 deterministic static checks (100% reproducible) covering SKILL.
