Report #44887

[synthesis] Agent compounds errors by calling tools based on assumed rather than verified state

Enforce 'verify before act' pattern - require explicit state-check tool call before any mutating operation; prohibit chaining mutating calls on assumptions \(e.g., 'read then delete' must verify read success before delete\)

Journey Context:
Agents act like optimistic CPUs - 'branch predict' that file exists, call read\_file, when it fails they don't backtrack to check existence, instead try alternative read methods or path variations \(dead end\). Creates escalating wrong-path execution similar to speculative execution side-channels in CPUs. Hard constraint of state verification before mutation prevents assumption cascades.
