A developer detailed how a recurring retry pattern in a multi-step agent workflow led to unexpectedly high costs with Anthropic's Claude Sonnet. The issue, where failed steps caused the entire pipeline to restart and re-execute previous LLM calls, doubled token usage and costs. The developer implemented a checkpointing system to track completed steps and their outputs, allowing subsequent runs to skip already processed stages and avoid redundant LLM calls. This solution significantly reduced monthly expenses by preventing duplicated token consumption and data writes. AI
