Mapping Technical Debt: How Semantic Graphs Reveal What Coding Agents Miss
Blog post from Epsilla
Technical debt is identified as a structural issue rooted in the complex relationships between components in a codebase, rather than merely being about lines of code, with AI coding agents struggling to address this due to their inability to understand the global impact of functions. By converting codebases into graph databases, invisible structural debt becomes visible and queryable, allowing high-risk functions and architectural bottlenecks to be pinpointed, as demonstrated by an open-source experiment with the OpenClaw repository using the tool CodeGraph. This method highlights the limitations of current AI agents, which can analyze functions locally but lack the systemic understanding needed to assess "fan-in," or the systemic importance of functions, posing risks during complex refactoring tasks. The experiment revealed significant insights into the repository's structure, such as identifying "zombie code" and critical architectural bottlenecks, and led to the development of Epsilla's Semantic Graph, which extends beyond code to include documentation, tickets, and APIs. This comprehensive structure provides the necessary context for Agent-as-a-Service platforms to operate safely and effectively, by offering a holistic view of the system and its dependencies, thus transforming AI agents into responsible, context-aware engineering partners.
