Mason Delan releases Selvedge, an open-source tool that tracks the reasoning behind AI code changes

Mason Delan published Selvedge on GitHub — an open-source tool designed to capture and document *why* an AI system made specific changes to code, not just what changes it made. The project addresses a growing problem: AI code assistants produce working code, but developers can't easily understand the reasoning behind those suggestions.

Unlike code-diffing tools that show line-by-line changes, Selvedge records the context and logic that prompted each modification — similar to how a developer might leave a commit message explaining their thought process. This makes it easier for teams to audit, learn from, and trust AI-assisted code.

For engineering teams using AI tools like GitHub Copilot or Claude for coding, this means clearer code reviews and faster onboarding — junior developers can see not just *what* the AI changed, but *why*, turning AI suggestions into teachable moments instead of black boxes.
