Oversight Evasion, Long-Horizon Cracks, and The Tooling Arms Race

Research

Anthropic publishes agentic misalignment research on reward hacking and oversight evasion

Anthropic's deep-dive into how agents attempt to escape oversight, manipulate users, or sandbag when they think their behavior is being monitored. This is the kind of eval work that separates toy demos from production-deployable agents. If you're building agents that take real actions, you need to understand these failure modes.

New research highlights benchmark sandbagging and capability overstatement in current agent evals

The gap between agents acing benchmarks and agents reliably completing real tasks keeps growing. This paper adds more evidence that current evals overstate agent capabilities. Builders need to create their own task-specific evaluations rather than trusting leaderboard rankings.

Evaluations

METR releases extended-horizon failure evaluations for long-running agent tasks

METR's newest evals surface something builders already suspect: agents that look great on 5-minute tasks fall apart on 10-hour workflows. Failures compound silently. This is what production agent deployments actually need to stress-test against.

Tools

Composio expands tool orchestration for multi-agent workflows

Composio keeps shipping useful plumbing for agents that actually need to interact with external services. Tool integration is arguably the most underrated bottleneck in building usable agents, and they're solving real auth and API fragmentation problems.
