AI Developer Tools

Selvedge

Selvedge captures the reasoning behind AI agent code changes, storing why a change was made alongside the code for future reference.

What is Selvedge?

Selvedge is an open-source tool that records the reasoning from AI agents during code changes, enabling developers to query the 'why' behind modifications using commands like `selvedge blame`.
