Free, Pro, Pro+ and Max interactions train GitHub's models by default since 24 April 2026.\n\n**Harness².** Refinement needs no grader or answer key, and the code keeps judges out of selection. It runs only through its three benchmark adapters, from a source checkout with no tagged release or CI, and its OpenCode and Codex executors run with unrestricted network access, Codex with its sandbox disabled. The benchmark gains are the authors' claims.\n\n## Before you call either\n\n### GitHub Copilot CLI\n\n1. Pass `--deny-tool` for anything destructive. It wins over `--allow-all-tools` and `--allow-tool`\n2. Turn on the sandbox with `/sandbox enable` or `--sandbox`. It's off by default\n3. Turn off model training in Copilot settings on Free, Pro, Pro+ and Max. It's on by default since 24 April 2026\n4. Move off Claude Opus 4.8, Claude Opus 5 and GPT-5.6 Terra before 16 November 2026\n5. Use a fine-grained token with only the Copilot Requests permission in `GH_TOKEN` for CI\n\n### Harness²\n\n1. Don't plan to call Harness² as a service. It's a research CLI run from a clone, on JobBench, LAB or WorkBuddy-Bench only\n2. Ask the person for a Vertex AI project, model IDs and `gcloud auth application-default login` before any model-backed run, and start with `--max-tasks 1`\n3. Run executors behind an egress firewall and block huggingface.co and github.com after setup, as the docs advise, so rubrics can't be fetched\n4. Write .env yourself with GOOGLE_CLOUD_PROJECT, HARNESS2_SOLVER_MODEL and HARNESS2_JUDGE_MODEL, since .env.example isn't shipped, and never commit it\n5. Use the same benchmark, executor, `--k`, `--mode` and seed for `harness2`, `harness2-judge` and `harness2-report`, or the results won't line up\n\n## Questions\n\n### Which is better for AI agents, GitHub Copilot CLI or Harness²?\n\nGitHub Copilot CLI scores 58.3 (C) on agent readiness against Harness²'s 41.6 (E), and leads in 6 of 7 scored categories.\n\n### Are GitHub Copilot CLI and Harness² open source?\n\nNo open-source release is listed for GitHub Copilot CLI. Harness² is open source (Apache-2.0. Bundled benchmark runners keep their upstream licences (Apache-2.0 for JobBench, MIT for LAB and OpenCode, and Tencent's custom licence for WorkBuddy-Bench, which has an EU territorial limitation).).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/github-copilot-cli-vs-harness2.json, and with the fewest tokens: https://www.anchorterminal.com/compare/github-copilot-cli-vs-harness2.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"github-copilot-cli\", \"b\": \"harness2\"}`.
