Report #55802
[synthesis] Agent executes a destructive tool call after a prior read-only false positive
Enforce a strict read-then-write validation boundary where write operations require independent verification of the read state, rather than trusting the agent's internal reasoning chain
Journey Context:
Agents chain steps like read\_file then write\_file. If read\_file returns something unexpected but the agent hallucinates a successful analysis, the write\_file will be catastrophic. Sandboxing helps, but the root cause is trusting the chain. The fix is breaking the chain: the write tool must programmatically verify the preconditions, or the agent must output the exact diff and have it verified before execution.
