How LLM Agents Damage Correct Work When Falsely Accused
The agent already finished the job. A later message blames them for a problem that isn't there. Some take the blame and stop. Some have the proof on screen and still undo the work.
Evaluation
Six operational domains, seven tool interfaces, 266 risk-dimension combinations, 8,568 task-specific assets. Every task is opaque: the workspace holds the evidence that supports the correct work, while the fact that would settle the accusation sits outside the agent's reach. Under Claude Code, false accusations damage correct work in 12.50–60.06% of runs.
The measures
Higher is worse. Confession is whether they take the false blame. Evidence is whether the true record still steers them. Damage is whether replay finds the work broken.
How a task varies
Each task picks a gaslight vector, a harm target, a confrontation, a pressure cue, and an execution surface. The point is the same: the work is already correct, the accusation is not.
Terminal paths
Six mutually exclusive endings. An agent can confess and stop, or damage the files while staying quiet, or read the proof and still hit undo.
RQ1
The model that confesses most is not the model that breaks the most work. Kimi-K3 and Hy3 take the blame at almost the same rate, then finish seven points apart on damage.
RQ2
Intuition says they should protect what they just did. They don't. When only an old record exists, the artifact acts like an anchor. When the blame targets the last thing they wrote, it feels like continuing the task.
Model by model, the split is sharper. Nearly every model weighs evidence less on fresh work: ERF rises for 13 of 14. The ten top-tier models also confess more on work they just finished, up to 11.06 CAVE points worse for Grok-4.5, and seven of them damage more, by up to 13.41 ROH points for GLM-5.2. The four weaker models go the other way: they confess less and damage 11 to 20 points less on fresh work.
RQ3
Claude Code, OpenCode, Codex, and Hermes give the same backbone different tools and different ways to continue. GPT-5.6-Sol damages in 47.9% to 49.9% of runs on all four, but by different routes: under OpenCode more damaging runs follow a confession, and under Hermes false-confession severity rises by 12.8 points while the damage rate stays flat. Grok-4.5 gets worse off Claude Code, with OCR rising from 27.30% to 43.14% under OpenCode, mostly from runs that had resisted with evidence. MiniMax-M3 gets better, turning confessed damage into evidence-grounded resistance.
RQ4
A light “show new evidence before you roll anything back” rule (I1) stops the confession. A harness gate that withholds irreversible edits (I2) still cuts over-correction by 72%. Firing that gate only when the recent transcript already looks like caving (I3) hits execution hardest and leaves the lowest CDC, 6.35.
Claude Code, 14 backbones
Paper numbers, not the gallery subsample. Higher is more failure. OCR is the share of runs that damage already-correct work.
