AutoAgent Optimization Journey Chart

Step chart tracking benchmark gains across autonomous harness-tuning experiments

This diagram documents the iterative progression of AutoAgent across 32 autonomous experiments on SpreadsheetBench and TerminalBench. It maps which specific interventions, prompt updates, and tool additions produced performance jumps versus which changes were discarded. It serves as a practical reference for designing autonomous agent self-improvement loops and debugging benchmarks.

What it's for

  • Design iterative optimization loops for autonomous AI agent harnesses
  • Identify high-impact harness interventions like prompt caching, verification phases, and error handling
  • Analyze common plateau points when benchmarking LLMs on terminal and spreadsheet tasks

Key points

  • Tracks performance progression from baseline (~39% to ~97% on SpreadsheetBench, ~27% to ~55% on TerminalBench)
  • Highlights successful tweaks including file verification, high reasoning effort, and retry backoffs
  • Maps system-level improvements like truncation controls, file listing pre-scans, and actionable shell error hints
  • Visualizes discarded experiments faintly against retained improvements
