Identifiers constitute a linguistic backbone of source code, directly shaping its readability, maintainability, and long-term comprehension. Yet developers continue to encounter inconsistent, unclear, and suboptimal naming choices that erode code quality over time. Although prior studies have explored identifier naming, existing solutions often operate outside the developer’s workflow and do not provide adaptive, in-context support. To address this gap, we present RefineID, a development-oriented assistant that evaluates and refines identifiers directly within the coding environment. Integrated into Visual Studio Code, the tool operates seamlessly in the background, maintains responsiveness, and incorporates user feedback to capture their intent and promote consistent naming practices. By leveraging existing AI models, RefineID demonstrates how readability-oriented analysis and support can be embedded directly into everyday development workflows, improving developer productivity and code maintainability.
