CooperBench/qwen35-9b-git-coop

What this is

Cooperative two-agent coding dataset: 211 task pairs across 18 repos, generated with mini_swe_agent on Qwen/Qwen3.5-9B in coop setting with a shared read-only git remote (--git). Agents coordinate via messaging and git fetch team; patches are auto-merged after both submit.

How it was generated

cooperbench run --setting coop --git -a mini_swe_agent -c 30 qwen35-9b-git-coop

Model served via vLLM OpenAI-compatible endpoint (openai/Qwen/Qwen3.5-9B).

File layout

• index.csv — one row per task pair; HF Dataset Viewer entry point
• qwen35-9b-git-coop/coop/<repo>/<task_id>/<features>/ — raw per-pair artifacts: result.json, eval.json, agent1_traj.json, agent2_traj.json, agent{1,2}.patch, conversation.json

log_dir column in index.csv points to the per-pair subdirectory.

Schema highlights for mid-training

Filter on: both_passed=true, model, agent_framework.

metadata JSON carries per-agent statuses, steps, merge outcome, per-feature pass — use json.loads(row["metadata"]) without following the pointer.

Note: total_tokens is 0 for this run — token counts are in agent_full_traj.json under messages[*].extra.response.usage (~116.1M total in+out).

Caveats

• step_limit=300 (3× default); 14.2% LimitsExceeded exits (60/422 agent slots) still present
• 42.9% merge conflict rate (90/210) — conflicts skip evaluation
• Token fields in result.json are 0; aggregate from agent_full_traj.json if needed
