parthh01/sphinx is a Git hook that, in agent-assisted development, checks whether you understood the changes before pushing to a protected branch. The approach described in the README briefly pauses the push, and a reviewer model, separated from the conversation that produced the code, reads the commit diff and then asks questions. Once the answer passes, the interrupted push resumes. This repository does not provide the latest release information, so it cannot be described as a change in a specific version.
The reviewer examines the committed changes with read-only Git tools and asks about the code's behavior, the situations in which it fails, and the conditions that must be respected. If the answer is wrong, it explains the grounds and presents a different scenario. The conversation record that produced the code is not passed to the reviewer, so this is separated from self-verification that relies on the same context. The focus of the questions is also on how the actual code behaves, rather than general concepts such as latency or inconsistency. The purpose of this tool, therefore, is not to block code generation but to confirm whether the changes were understood.
However, the README limits it to a practice tool rather than a security gate. Usage costs arise, credentials may be exposed, and there is also the possibility of bypassing the hook and of reviewer model errors. A push can be stopped for up to 25 minutes, so there is a chance that the work flow is broken by a shell timeout or a false alarm. Therefore, passing cannot be regarded as a guarantee of code safety; it is more accurate to view it as an understanding check that makes you explain the changes.
