Tool Agents Need Taint Boundaries, Not Bigger Scopes
APPA landed on arXiv on 27 July 2026 with a blunt result for tool-agent security: permission prompts are too late once poisoned or confidential data has...
Chip-Design Agents Need Token ROI, Not Demo Flows
FluxBench landed on arXiv on 20 July 2026 with a useful warning for chip-design teams: two agents can start from the same foundation model and still...
Terminal Agents Need Progress Curves, Not Victory Screens
Long-Horizon-Terminal-Bench landed on arXiv in July 2026 with an awkward result for terminal-agent buyers: even the strongest tested model still failed...
Million-Token Context Still Fails the Workload Test
Anthropic reported on February 5, 2026 that Claude Opus 4.6 scored 76% on the 8-needle 1M-token MRCR v2 test while Claude Sonnet 4.5 scored 18.5% on the...
Agent Evals Need Harnesses, Not More Scoreboards
AgentCompass first landed on arXiv on 15 July 2026 with a practical complaint: agent evaluation is fragmented, tightly coupled, and hard to reproduce...
Coding Agent Benchmarks Hit the Generalization Wall
Scale's SWE-Bench Pro public leaderboard reports that top models scoring above 70% on SWE-Bench Verified fall to 23.3% for OpenAI GPT-5 and 23.1% for...
Agent Test-Time Scaling Needs Reuse, Not More Rollouts
General AgentBench reports that running agents for more interaction steps or more sampled trajectories did not reliably improve ten leading agents,...
Multi-Agent Finance Workflows Need Cost Curves, Not More Agents
A March 2026 benchmark on financial-document processing makes the uncomfortable point: the most accurate multi-agent architecture was not the obvious...
Self-Improving Agents Have an Evaluator Problem
Anthropic's June 2026 update on recursive self-improvement is not a distant sci-fi warning. The company says its engineers now ship 8x as much code per...
Coding Agents Need Trajectory Reviews, Not Pass Bits
Most coding-agent benchmarks still compress a whole run into one bit: did the task pass? AgentLens argues that users experience the whole trajectory...
