[counterintuitive] LLM agents reliably complete multi-step tasks autonomously

Design agent loops with bounded steps, deterministic verification, human checkpoints for irreversible actions, and graceful degradation; assume compound error, not compound success.

Journey Context:
Research on LLM agents shows that error rates compound over multi-step plans: a model with 90% per-step accuracy drops to roughly 35% accuracy after 10 steps. Zhang et al. showed that hallucinations can snowball as models justify earlier mistakes. SWE-bench found that even frontier models struggled to resolve real-world GitHub issues end-to-end. Reasoning models and tool use improve reliability but do not eliminate compounding failure, distribution shift, or misinterpretation of tool outputs. The right model is human-supervised, bounded autonomy with verification at each step, not open-ended delegation.
