Using a real workflow-triage script that makes 26 underlying API calls, the team measured a ~126x reduction in characters reaching the agent's context (25,811 vs ~3.26M), cutting cost from ~$2.44 to ~$0.02 per run on Claude Sonnet 5. The post details exactly what was measured vs. extrapolated, includes the full script source, and prices the token savings across five current LLM models. The core insight: intermediate tool results that stay inside the execution environment never inflate the model's context window. ## Full article daily.dev links to this article rather than hosting it.
