Report #36465

[synthesis] Agent confidently executes multiple consecutive steps based on a false intermediate assumption

Inject state validation checkpoints where the agent must compare its internal belief of the system state against a ground-truth observation \(e.g., git status, ls, or a read-back\) before proceeding to the next major step.

Journey Context:
Agents are trained to complete tasks, creating a bias toward continuing rather than halting. If step 1 fails silently \(e.g., writes to the wrong directory\), step 2 uses the wrong path, and step 3 deletes the wrong files. People try to fix this with 'better prompting,' but the root cause is the lack of feedback loops in the execution environment. The alternative is running the whole plan and checking at the end, but by then, the failure is catastrophic. The right call is mandatory intermediate state assertions.
