 "repo_url": "https://github.com/google-research/harness2",
 "repo_slug": "google-research-harness2",
 "title": "Try both recursion modes locally with no credentials",
 "page_title": "How to try both recursion modes locally with no credentials with Harness2",
 "summary": "Run the bundled demo to see parallel and sequential harness refinement before spending any API budget.",
 "who": "A developer or researcher evaluating Harness² who wants to see how the two recursion modes behave before configuring any model access.",
 "problem": "Setting up model-backed benchmarks takes time and costs money, so it is hard to judge the framework before committing.",
 "outcome": "A completed local demo run under runs/demo that shows both recursion modes using deterministic editors and real Python executions.",
 "steps": [
  "Create the environment with `uv venv --python 3.12 .venv`",
  "Activate it with `source .venv/bin/activate`",
  "Install the package with `uv pip install -e '.[render]'`",
  "Run the demo with `harness2-demo --output runs/demo --k 2`",
  "Review the results saved under runs/demo and compare the two recursion modes"
 ],
 "agent_prompt": "In the google-research/harness2 repo on Linux with Python 3.12 and uv, create the environment, install with uv pip install -e '.[render]', and run harness2-demo --output runs/demo --k 2. Report the files written under runs/demo and summarize what each recursion mode produced. Verify that the run finished without model credentials being configured.",
 "agents": [
  "any"
 ],
 "difficulty": "Intermediate",
 "time": "30 minutes",
 "basis": "readme",
 "caveat": "The demo uses deterministic editors, so its output shows how the modes run, not how well they perform on real benchmarks.",

 "lang": "python",
 "requirements": [
  "Linux, Python 3.12, and uv",
  "For the local demo: nothing else, since it needs no model credentials",
  "For model-backed runs: Node.js 20+, the Google Cloud CLI, a Vertex AI project with model IDs, and API budget",
  "For LAB: Pandoc and Poppler. For WorkBuddy-Bench: Docker"
