2,151 IPs banned from The Cutting Room Floor wiki for Claude Code scraping
2,151 unique IPs hit The Cutting Room Floor wiki with Claude Code and got banned — sites are actively blocking agent traffic. Worth noting for anyone running agents against public wikis.
Closed-World Resolution Against Tool Hallucination in LLM Agents
Proposes closed-world resolution to stop LLM agents from hallucinating tool calls — a top production failure mode when agents invoke tools that don't exist or misuse schemas.
MAGS: Multi-agent Auto-formalization Guarantees Safety for Agentic Outputs
Multi-agent auto-formalization claims formal safety guarantees for agentic outputs — worth a look if you need verifiable agent behavior beyond prompt-level guardrails.
Do AI Agents Understand Computer Architecture?
Benchmark probing whether AI agents actually understand computer architecture — useful signal for coding-agent evals and where they break on low-level reasoning.
Launch HN: Skillsync (YC W26) – AI chat sessions made portable across agents
YC W26 launch: Skillsync makes AI chat sessions portable across coding agents — move context between Claude Code, Cursor, etc. 61 points, 53 comments on HN; the debate is whether cross-agent portability is a real workflow need or a solution looking for a problem.
Anthropic Life Sciences Verification Program
Anthropic opens Mythos, Opus, and Sonnet to life science professionals with more permissive biology safeguards — relevant for biotech agent builders needing domain-specific model access.
SoL-Pi: Recursively Scaling Auto-Research Loops for Efficient Agent Harness
Proposes recursively scaling auto-research loops for agent harnesses — targeting unattended coding agents that move beyond supervised code completion.
RetireOPD: Self-Retiring On-Policy Distillation for Agentic Reinforcement Learning
Self-retiring on-policy distillation for agentic RL — the distillation schedule adapts and stops when the student stops benefiting, instead of following a fixed plan.
@freyjavalentine.bsky.social: Saw a term calling the act of shitting out Claude code without review and expecting your coworkers to fix it
Bluesky thread coining a term for unreviewed Claude code dumped on coworkers — the 'agent slop' debate continues.
