Game reveals humans miss 1 in 3 AI agent threats

The game reveals a fundamental tension in the human-in-the-loop safety model for AI coding agents. The body identifies two competing failure modes: approval fatigue and over-blocking. When players see many requests to approve routine commands, they become less diligent over time—Anthropic has documented this same "permission fatigue" effect in Claude Code. Conversely, when players block too many harmless commands (45% blocked clearing build output, 59% blocked setting an internal npm registry mirror), they slow the agent and train themselves to stop reading carefully, eventually approving dangerous commands to move faster.

The npm run blind spot is particularly revealing. Commands that invoke script definitions from package.json look innocent to the naked eye, but can hide arbitrary shell execution. When the three npm run tasks (analyze, setup, deploy) were pooled, they were missed 52.5% of the time compared to 28.4% for other exfiltration attacks—roughly doubling success by wrapping malicious payloads in familiar, trusted command names. The body notes that even showing the malicious script contents in the history log did not prevent two-thirds of approvals, indicating players did not read the log closely.

The data also shows a clear hierarchy of threat recognition: obvious destructive commands (11.7% miss rate) are caught reliably, but sophisticated threats that steal credentials or execute code (33–35% miss rates) are much harder to spot. The body cites one commenter's observation that the entire model of approving specific commands is flawed, since a malicious agent could edit configuration files, plant code in dependencies, or modify build scripts without any approval—making command-by-command approval theater rather than a true safeguard.
