 "title": "Make a verified task harder and measure its difficulty",
 "page_title": "How to make a verified task harder and measure its difficulty with Evo Trace",
 "summary": "Derive a harder child task from a verified one, then measure it with fresh solver attempts.",
 "who": "A researcher building a difficulty curriculum for coding agents who needs measured difficulty rather than guesses from patch size.",
 "problem": "Easy verified tasks saturate quickly, and making a patch longer does not make a task harder.",
 "outcome": "A harder child task with a calibration result based on fresh solver attempts against the default target of two verifier passes in five attempts.",
 "steps": [
  "Install and launch Evo Trace with `curl -LsSf https://raw.githubusercontent.com/jinzijian/EvoTrace/main/install.sh | sh` and then `evotrace`.",
  "Make sure a verified asset exists and Docker is available.",
  "Run `/harden 1` to derive and test a harder child task.",
  "Run `/calibrate 2` on the child task to measure difficulty with self-play."
 ],
 "agent_prompt": "Using the EvoTrace repo at https://github.com/jinzijian/EvoTrace, run /harden 1 and then /calibrate on the resulting child asset in the DeepSeek Harness app. Report the calibration pass count out of attempts and the added behavior. Verify that the child task adds testable behavior, compatibility, edge cases, or failure constraints rather than only a longer patch.",

  "Existing Claude Code or Codex session history on the local machine",
  "Git, and Node.js 22.19+ or 24+ for the DeepSeek Harness app",
  "A model provider configured in Harness Settings for review, hardening, calibration, and evolution",
  "Docker, only when building or validating executable environments"
