SWE-bench

elizaOS's SWE-bench Lite harness. The canonical single-shot flow lives in cli.py (entry: python -m benchmarks.swe_bench …). Design notes and historical context live in this README.

Head-to-head comparison: elizaOS vs opencode

harness/comparison.py runs the same N SWE-bench Lite instances through two paths and emits a side-by-side JSON report:

• Path A — elizaOS uses the existing canonical bridge (cli._run_instance): prompt the TS bench server, extract a unified diff, grade with SWEBenchEvaluator.
• Path B — opencode clones the target repo at base_commit into a per-instance sandbox, invokes opencode run "<task>" in that workdir, then captures the working-tree diff via git diff and grades it with the same SWEBenchEvaluator. If opencode is not on PATH, each Path B record is marked status="skipped_opencode_missing" and the run continues.

Both paths share dataset loading, sandboxing, and grading so the only honest delta is the patch producer.

Run it

# Stub-only — emits the report schema with placeholder entries, no Docker,
# no eliza bridge, no opencode call. Use this to inspect the JSON shape.
python -m benchmarks.swe_bench.harness.comparison --n 2 --stub

# Real smoke (requires: docker, the eliza TS bench bridge, and opencode on PATH)
python -m benchmarks.swe_bench.harness.comparison --n 2

# Pin specific Lite instances
python -m benchmarks.swe_bench.harness.comparison \
  --instances django__django-11099 sympy__sympy-20590

A pre-generated placeholder report lives at harness/fixtures/comparison_smoke.json for downstream tooling that wants to lock in the schema before the first real run.
