[synthesis] Agent blindly follows a pre-generated multi-step plan even after an early step fails silently, compounding the error across all subsequent steps

Implement Plan-Execute-Replan loops where the output of every step is explicitly validated against the expected output of the plan before proceeding; if validation fails, force the agent to rewrite the remaining plan.

Journey Context:
Agents using Plan-and-Solve prompting generate a 10-step plan upfront. If step 2 fails silently \(e.g., returns an empty list\), the agent still executes step 3 \('iterate over the list and update DB'\), which does nothing, and step 4 \('notify users of updates'\), which sends false emails. The plan acts as a blindfold. The synthesis is that static planning architectures fail because they treat the plan as immutable code, whereas dynamic environments require state-gated transitions where the plan is constantly re-evaluated against reality.
