We removed over 80% of Claude Code's system prompt for more advanced models. How to apply the lessons we learned to your own context engineering in Claude Code and with your own agents.
This is directly applicable to the Claude-powered orchestrator that delegates to rails-expert, test-engineer, and investigator agents — leaner system prompts for advanced models could improve reliability and reduce token costs across all 20+ app interactions. The lesson that 80% of system prompt can be removed for capable models suggests the orchestrator's agent definitions and task delegation prompts should be audited and stripped down. This is especially relevant for high-frequency agents like the test-engineer automating Rails test suites or the investigator scanning app_monitor and code_quality apps, where prompt efficiency directly impacts throughput.
