Report #85886
[synthesis] Agent continues building on a fundamentally flawed approach because it already invested steps in it, leading to catastrophic architecture failure
Implement a pre-mortem evaluation step at key milestones. Before starting a new major phase, force the agent to evaluate if the current approach still aligns with the original goal, and give it an explicit abort and restart action with no penalty.
Journey Context:
Agents exhibit a form of the sunk cost fallacy. If Step 1 chooses a suboptimal library, Step 2 writes a wrapper, Step 3 writes a hack to fix the wrapper, by Step 5 the system is unmaintainable. Because agents lack the embarrassment humans feel about admitting failure, they don't naturally abort; they just keep patching. The synthesis is that you must provide an explicit architectural escape hatch. By forcing a pre-mortem, you interrupt the compounding technical debt before it becomes catastrophic.
