Eval Engineering

Flow

  • Inspect all inputs first: the repository, Harness, optional traces, existing Tasks and runs, existing World knowledge, and the human goal. Identify the source files and skill references that apply before proposing work.
  • Create or update the small project World Knowledge Skill from reusable facts in those inputs. Use it to propose one grounded Task.
  • Draft the Task Spec and World Skill together. Show both to the user, keep exact Task truth only in Task.md, and refine both until the user approves them.
  • Implement the approved Task, validate its Environment and Verifier, run the real Harness, inspect the full evidence, and fix only non-agent failures.
  • Reconcile the World Skill with what the run proved, then repeat this flow for the next Task.
