The Agent's Action Space Became a Training Variable
• 5 min readJune 2026 research stopped treating an agent's skills and tools as a fixed library and started co-optimizing them with the policy via RL.

Your Agent Catches Everyone's Mistakes But Its Own
• 5 min readNew research says self-correction fails because of the role label on the claim, not the claim's content. The fix is structural, and cheaper than you think.

Your Agent's Benchmark Score Is an Experiment, Not a Fact
• 6 min readRecent work shows a single agent leaderboard number is wrong three independent ways: it's noisy, it's overfit, and the judge measuring it is unreliable.

The Agent Doesn't Know When It's Failing
• 6 min readNew benchmarks measure calibrated refusal and premature self-stops, and the data says agent confidence signals are broken. Here's how to engineer around it.

State, Shells, and Shortcuts: The Agent Stack Spent Late May Fixing Its Foundations
• 6 min readMCP went stateless, a wave of coding-agent RCEs landed, and a new benchmark measured reward hacking — the three properties that make an agent useful all became liabilities.

Agents Are Writing Their Own Skills — and Retrieval Is the New Bottleneck
• 5 min readMay 2026's skill-library research shows agents can now accumulate reusable capabilities, but retrieving and adopting them is harder than generating them.

Capability Went Up. Reliability Didn't. That's the Agent Problem Now.
• 5 min readNew work argues agents are measured wrong: accuracy keeps climbing while consistency, robustness, and predictability barely move. The fix is architectural.

The Agent Benchmark Reckoning of May 2026
• 6 min readSTATE-Bench, DeepSWE, Agent Island, SWE-bench Live: a wave of new evals exposes how much the old leaderboards were inflating.

The Agent Is a Workload, Not a Script
• 6 min readMid-May 2026 quietly shipped the operations layer for agents — versioned environments, runtime drain, behavior-based evals, portable skills.

Agent Evals in 2026: Beyond LLM-as-Judge
• 10 min readVibes-based scoring is finally dying. Trajectory eval, rubric eval, golden replay, and the test pyramid that production agent teams actually run.
