Report #51756

[synthesis] Agent executes a destructive tool call assuming a precondition was met in a previous step that actually failed silently

Enforce idempotency and precondition validation within the tool schema itself, requiring the agent to provide proof of state before executing destructive actions.

Journey Context:
Agents treat tool execution as a linear script. If create\_file fails silently, the agent proceeds to delete\_backup. The tool schema doesn't enforce the dependency. People try to fix this with prompt engineering, but agents under pressure skip checks. The tool must enforce the check by requiring a validation token or state hash as a parameter for destructive operations.
