## Description

Chronos is an LLM software engineering agent and repository-scale debugging model designed for autonomous bug fixing. The system functions as an automated bug fixing system that localizes defects, reasons through root causes, and implements validated multi-file patches.

The project is distinguished by a graph-guided retrieval engine that uses a persistent memory graph to navigate call relationships and dataflows across large repositories. It employs a persistent debugging workflow that indexes a history of commits and logs to recognize patterns and avoid repeating previous mistakes across iterative debugging cycles.

The system covers root cause analysis through causal trace localization and logic-based bug tracing across multiple files. It further provides autonomous code repair by synthesizing patches and validating them within an iterative sandbox environment. Repository intelligence is handled via multi-hop contextual retrieval and multi-source ingestion of logs and traces.

The system provides reasoning step transparency and generates automated debug documentation, including risk assessments and justifications for every applied fix.
