  "account": "The recent experiment tested whether Claude Code could complete tasks involving repository modifications and deterministic checkers. The tests compared three configurations: bare Claude Code, Claude Code with a project-specific CLAUDE.md file, and Claude Code with RE-call memory. RE-call significantly improved success rates over the CLAUDE.md baseline, winning 17 out of 24 comparisons. Memory retrieval was successful in 83.3% of eligible sessions, with useful context retrieved 85.0% of the time. While memory improved the final score, the memory layer cost more in terms of API usage. The experiment demonstrates that a production memory layer can improve task completion accuracy, but further optimization is needed for retrieval efficiency.",
  "summary": "The first experiment measured whether Claude Code knew the right answer. This one measured whether the work actually succeeded. In my previous experiment , I tested whether a memory layer could stop Claude Code from confidently repeating project-specific mistakes. It did. But there was an obvious limitation. The tasks measured whether the answer was correct. They did not ask the agent to modify a…",
