📚 Co-RL: Unsupervised Reasoning Emerges from Diverse Cohort in Multi-agent RL — Cooperative multi-agent RL where peer-derived rewards replace human labels — reasoning emerges without supervised data. Relevant if you're exploring multi-agent training without reward engineering.

📚 SPADE: Self-Play in Adaptive Synthetic Executable Environments — LLM writes its own executable training environments and learns via self-play — environment scaling without hand-built simulators. Points at self-improving agent training loops.

📚 FM-Bench: A Benchmark for Long-Horizon Management with Competing Agents — Benchmarks LLM agents managing a football club over 20 simulated years with competing agents — long-horizon decision-making under competition. Useful eval for agents that need to sustain strategy, not just answer.

📚 Emergence of Agentic AI: A Review on Evolution, Background, Working Principles, Applications, Adoption Factors, and Future Research Directions — Broad survey of agentic AI — evolution, working principles, adoption factors, future research directions. Useful orientation if you're evaluating where agent frameworks are heading.

Multi-agent RL is moving from hand-crafted rewards and simulators to self-generated ones. If you're building agent training pipelines, the bottleneck is shifting from data to environment design.

💬 Bounded Agents: Delegation Security for Multi-Agent AI Systems — Agentic Principal Chain enforces session-aware authorization to block harmful action combinations and delegation abuse in multi-agent systems.

💬 Looped Language Models Improve Compositional Tool Calling — Looped LMs use recurrent computation for multi-step tool use, with adaptive inference balancing accuracy and compute.

Security and tool-calling reliability are the two threads the community is pulling on this week — both papers point at concrete failure modes operators will hit.

💬 SWE-bench Science: Can Coding Agents Resolve Engineering Tasks in Science? — New benchmark extends SWE-bench to scientific codebases; agents struggle with domain-specific failures and scientific guidance helps only sometimes.

💬 SkillGate: Training In-Policy Skill Selection in Long-Horizon Agents — SkillGate fixes selector credit starvation in agent skill selection by separating outcome credit for execution tokens from local advantage.

Three papers converge on the same theme: agent reliability is still fragile — memory can mislead, skill selection needs better credit assignment, and coding agents stumble on domain-specific tasks.
