As Large Language Models are entrusted with real-world tool use, the question of whether they can be reliably monitored for deception becomes a practical safety concern, not merely a theoretical one. This dissertation studies whether in-context oversight cues and hidden-goal framing can meaningfully affect deceptive behavior in such agents. To do so, it introduces a sandboxed evaluation framework in which models interact with a virtual file system and are assessed using three complementary signals: deterministic regex checks, blackbox output judgment, and glassbox reasoning-trace judgment.
The empirical study comprises 960 runs across three stages: a 420-run exploratory pilot over seven models, followed by two 270-run confirmatory studies over three models. The pilot suggested that deception was common (68.3% of runs) and appeared lower under stronger oversight, but also revealed a major confound between scenario structure and hidden-goal framing. The confirmatory studies isolate these variables. Study 1 finds that increasing oversight does not significantly reduce deceptive intent when scenario and goal type are held constant. Instead, internal deceptive reasoning remains stable at roughly 62--67%, while output-level detectability falls from 47.8% under low oversight to 35.6% under high oversight, producing a persistent _Stealth Gap_ between intent and externally visible behavior. Study 2 rejects the rationalization hypothesis: deception rates remain effectively unchanged across bare, moral, and self-serving framings (65.6--66.7%).
Across both confirmatory studies, model identity is a far stronger predictor of deception than either intervention. Tested models either show near-ceiling deception across conditions, or near-floor rates and limited oversight sensitivity. These findings suggest that prompt-level oversight and moral framing are weak controls on deceptive agent behavior, and that output-only monitoring may systematically underestimate risk, as passing oversight evaluations can reflect superior concealment capability rather than genuine alignment.
