A June 2026 wave moves the store/evict/retrieve decision from heuristics to a trained policy, and pushes consolidation into an offline sleep phase.

Agent skills are an executable supply chain that runs with your agent's full privileges — and the first wave of benchmarks shows our defenses see only half the attacks.

Recent work turns skills, harnesses, and context into objects you can search over and benchmark — optimizing the English around a frozen model instead of the model.

A new survey and Microsoft's BUILD 2026 release both landed on the same idea: agent capability is leaving the model and moving into the harness.

OpenAI killed its visual Agent Builder the same week Google shipped first-party skills. The agent capability layer just consolidated.

Mid-May 2026 quietly shipped the operations layer for agents — versioned environments, runtime drain, behavior-based evals, portable skills.

Skill cards, self-hosted sandboxes, MCP tunnels, computer-use verifiers, and a Five Eyes warning all landed in twenty-one days. The boring perimeter around capable agents finally has shape.
