Enhanced Reuse Agent for Intelligent License Reuse

The current reuse workflow in FOSSology provides a powerful mechanism to copy license clearing decisions from a previously analyzed upload to a newer version. However, this process remains largely mechanical and opaque, offering little insight into what has changed between versions after reuse is applied. As a result, users must manually inspect differences to understand the impact of reuse, which becomes increasingly difficult for large codebases and frequent updates. To address this limitation, this project proposes the development of an Enhanced Reuser Agent that adds an intelligent analysis layer on top of the existing reuse workflow. The agent runs automatically after scanners complete and reuse decisions are applied, comparing the previously cleared upload (v1) with the new upload (v2). It generates insights such as a diff-aware file tree, license comparison, aggregated statistics, and a risk-level summary. In addition, a Smart Reuse (Suggested Matches) mechanism automatically identifies and recommends similar previously-cleared uploads, reducing the manual effort required to search for suitable reuse candidates. By providing a clear and interactive view of structural and license-level changes, along with proactive reuse suggestions, the system enables users to better understand the outcome of reuse and efficiently refine decisions where needed. This transforms reuse into a more transparent and insight-driven process, reducing manual effort and improving overall usability while remaining fully compatible with the existing FOSSology workflow.
