EviACT: An Evidence-to-Action Framework for Agentic Program Repair
For automated program repair, EviACT provides a more effective and efficient agentic approach by integrating execution evidence into the repair pipeline.
EviACT introduces an evidence-to-action framework for agentic program repair, improving resolve rate by 1.6-6.0 percentage points over baselines and reducing API costs by 70.1-88.6%.
LLM-based agents have moved automated program repair (APR) from fixed-context patch generation to interactive repository-level repair. However, existing agentic APR systems still struggle to use execution evidence to guide localization, patch generation, and validation. We propose EviACT (Evidence-to-Action), an agentic APR framework that coordinates three evidence-driven guardrails across repair stages. The retrieval scaffold grounds repair context, the compile gate filters invalid edits, and the test-driven gate checks target-test recovery before full regression. Across four benchmarks, EviACT improves resolve rate over the strongest reported comparable baselines by 1.6-6.0 percentage points and shows 70.1-88.6% lower reported per-bug API cost where baseline costs are available. Ablations and diagnostics suggest that these gains are associated with the coordinated evidence-to-action chain, making agentic APR more effective and efficient.
