[synthesis] Agent treats early reasoning assumptions as established facts, building increasingly elaborate wrong structures on a faulty foundation

Explicitly tag assumptions in the agent's reasoning chain. At each major decision point, require the agent to list its active assumptions and re-evaluate them against available evidence. Use assumption-hunting prompts that specifically ask 'What if this assumption is wrong?' before committing to a path. Implement backtrack points where the agent can revert to a pre-assumption state.

Journey Context:
Chain-of-thought prompting \(Wei et al., 2022\) improves reasoning by building step-by-step. Tree-of-thoughts \(Yao et al., 2023\) explores multiple reasoning paths. The premature commitment anti-pattern from software design warns against locking in decisions too early. The synthesis reveals that CoT's strength is also its critical weakness in agent systems: once an assumption is stated in the reasoning chain, it becomes locked in as a premise for all subsequent reasoning. The agent doesn't revisit it because it's 'established.' Even if later evidence contradicts the assumption, the agent has already built too much reasoning on top of it to backtrack—it would need to regenerate everything from the assumption forward. This creates a ratchet effect that locks in errors. The longer the chain, the more costly revision becomes, and the more the agent rationalizes contradictory evidence to fit the locked assumption rather than revising it.
