Claude Build DayAGET-Bench — a benchmark for governance-overlay agent behavior. This public slice asks: does a coding model's rule-compliance degrade as more rules are presented to it? Compliance is computed by a deterministic rule-checker executed against the model's generated code — never self-reported. Result: density-invariant for Opus 4.8 — compliance holds across a 4× range of rule count (5 / 10 / 20 rules: 80% / 75% / 76%, 95% CIs overlap). Build Day is the public release of this ongoing benchmark, with transparent handling of degenerate (prose-only) runs.
