author-contributions
Identify all files a specific author contributed to on a branch vs its upstream
by microsoftFree
Description
author-contributions is an agent skill from the Microsoft VS Code repository, listed on skills.sh. It finds every file a specific author contributed to on a branch, compared with an upstream branch such as main, and it traces contributions through file renames. The skill gives a procedure: first identify the author's exact git identity from the log, because short usernames do not match full display names, then collect the files the author committed directly, and then follow renames to pick up work done under an earlier file name. The output is a simple markdown table with the status of each file, DIRECT or VIA_RENAME, the file path and the line counts added and removed, followed by a summary. Because it runs many sequential git commands, the skill suggests delegating it to a subagent. It applies when someone asks who edited what, or what code an author contributed on a branch.…
