Report #78938

[synthesis] Catastrophic destructive tool calls caused by cascading partial state assumptions

Require a dry-run or state verification step before any destructive mutation \(write, delete, deploy\), where the agent must output the exact expected state diff and have it validated against the actual current state.

Journey Context:
Agents often execute a sequence of reads, form a mental model of the state, and then execute a write. If a read fails silently or returns stale data, the agent's mental model is wrong. Because it is confident in its prior steps, it proceeds with a destructive action based on the poisoned model. The synthesis is that read failures or stale reads create a poisoned mental model that the agent trusts implicitly, so destructive actions must be decoupled from immediate prior reads and require independent state verification.
