A new benchmark methodology for evaluating repository-level software engineering systems in a time-consistent manner

advanced Published 30 Mar 2026
Action Steps
  1. Snapshot a repository at a specific point in time (T0)
  2. Construct repository-derived code knowledge using only artifacts available before T0
  3. Evaluate software engineering systems on tasks derived from pull requests merged after T0

Title: ATime-Consistent Benchmark for Repository-Level Software Engineering Evaluation

Abstract:
arXiv:2603.26137v1 Announce Type: cross Abstract: Evaluation of repository-aware software engineering systems is often confounded by synthetic task design, prompt leakage, and temporal contamination between repository knowledge and future code changes. We present a time-consistent benchmark methodology that snapshots a repository at time T0, constructs repository-derived code knowledge using only artifacts available before T0, and evaluates on engineering tasks derived from pull requests merged
