# PyTorch PR Review Skill Review PyTorch pull requests focusing on what CI cannot check: code quality, test coverage adequacy, security vulnerabilities, and backward compatibility. ## Usage Modes ### No Argument If the user invokes `/pr-review` with no arguments, **do not perform a review**. Instead, ask the user what they would like to review: > What would you like me to review? > - A PR number or URL (e.g., `/pr-review 12345`) > - A local branch (e.g., `/pr-review branch`) ### Local CLI Mode The user provides a PR number or URL: ``` /pr-review 12345 /pr-review https://github.com/pytorch/pytorch/pull/12345 ``` For a detailed review with line-by-line specific comments: ``` /pr-review 12345 detailed ``` Use `gh` CLI to fetch PR data: ```bash # Get PR details gh pr view <PR_NUMBER> --json title,body,author,baseRefName,headRefName,files,additions,deletions,commits # Get the diff gh pr diff <PR_NUMBER> # Get PR comments gh pr view <PR_NUMBER> --json comments,reviews ``` ### Local Branch Mode Review changes in the current branch that are not in `main`: ``` /pr-review branch /pr-review branch detailed ``` Use git commands to get branch changes: ```bash # Get current branch name git branch --show-current # Get list of changed files compared to main git diff --name-only main...HEAD # Get full diff compared to main git diff main...HEAD # Get commit log for the branch git log main..HEAD --oneline # Get diff stats (files changed, insertions, deletions) git diff --...
