The baseline’s instructions say “answer Python questions concisely.” The candidates add: “Look up current release information with web fetch instead of answering from memory.

For upgrades, cover every release between the current and target version, and check the user’s code before giving a verdict.” doctl harness-runtime config list Pick the metrics . Use the UUIDs of the conversational metrics you want to measure: doctl evaluation metric list --format UUID,Name,Category Create the scenario set .
