Metrics Failure in LLM-Based Code Vulnerability Repair: An Empirical Study and a Change-Aware Screen
arXiv cs.AI · Published · 3 min read

- What happened
- Researchers found that compile rate, the standard metric for LLM-based C/C++ vulnerability repair, is unreliable and fails to reflect actual code quality improvements.
- Why it matters
- Security engineers and ML researchers evaluating automated vulnerability repair tools need to know this before trusting compile-rate benchmarks or deploying such systems.
- Watch out
- The study tested only 203 functions and three models; findings may not generalize to larger codebases, different vulnerability types, or newer LLM architectures.

The patterns behind this
- Automatic Prompt Optimization
- Agentic Context Engineering (Evolving Playbook)
- Structured Reflection (Think Tool)
Each one covers how the technique works, when it earns its cost, and where it breaks.
