Git Tree Review Flow

How CodeSubmit turns a repo into a review map

CodeSubmit does not jump from a C++ take-home straight to a thumbs-up or thumbs-down. The review flow starts by mapping the full git tree, then filtering obvious generated and vendor noise so reviewers get a fair file map before deeper review begins.

File listings alone do not decide anything. The tree is the map, then reviewers read the README, manifests, and top-modified files that explain how the submission works before they turn it into a candidate-friendly take-home review and a sharper CodePair follow-up.

Fair-review baseline

File listings are discovery, not evidence. Generated and vendor noise gets filtered so the review starts from candidate-authored work.

Map the tracked repo

The first pass builds a real file map so the review starts from the submitted project, not a stereotype about the stack.

Filter to reviewable files

Noise gets filtered out early so reviewers spend time on candidate-authored work instead of generated scaffolding.

Anchor to the root files

README and top-level manifests explain how the project is meant to work before deeper inspection begins.

Carry it into follow-up

That repo map turns into concrete review notes, likely test files, and live follow-up prompts for the hiring team.

The result is a cleaner handoff for hiring teams: concrete paths to inspect, stronger AI summaries, and live follow-up topics that stay anchored to the repo.
