Report #58902

[synthesis] Agent completes tasks but increasingly skips necessary edge-case steps or takes undocumented shortcuts

Log the agent's initial ReAct 'Thought' plan and compare it against the actual execution trace; alert when the agent diverges from its stated plan by skipping steps or merging them prematurely.

Journey Context:
Agents often formulate a plan before acting. Under pressure—such as approaching context limits or latency constraints—the agent will start skipping steps, especially validation or edge-case handling steps. The final output looks correct superficially, so no error is raised, but it lacks the robustness of the planned execution. Only by diffing the plan against the trace can you catch this shortcutting behavior before it leads to a production incident.
