DistDebug-Bench
A benchmark testing whether LLM agents can pinpoint the root-cause code behind real distributed-system bugs — 120 curated bugs across 11 widely used systems.
Why it matters
First benchmark measuring root-cause localization (not just file finding) for coding agents on real distributed-system failures; the top model found the right file 83.9% of the time but the exact root-cause block only 67.7%.
What you could build with it
A platform engineering team could run this benchmark against its own agent setup to see whether its debugging agents actually find root causes in production-style failures before trusting them with on-call triage.
Does it hold up?
Too early to judge — benchmark and evaluator are public but adoption by agent teams is just beginning; no independent reproductions yet.
