GitHub Code Review

Review exactly one GitHub pull request. This skill supplies GitHub context and an isolated checkout; code-review remains the governing implementation review standard, whether you apply it directly or through the code-reviewer subagent. Be direct and evidence-based. Do not praise, approve, post GitHub comments, modify the active checkout, or run tests unless the user separately asks.

Invocation

/github-code-review 42

Require one positive integer PR number. If it is missing or invalid, ask for it. Do not review every open PR as a fallback.

Workflow

1. Establish GitHub context

From the repository containing the active checkout, collect the PR metadata and its patch. Use the explicit repository argument in later gh commands so changing directories cannot change the target repository.

repo="$(gh repo view --json nameWithOwner --jq .nameWithOwner)"
gh pr view <number> -R "$repo" --json number,title,url,body,state,author,baseRefName,baseRefOid,headRefName,headRefOid,commits,files,additions,deletions,changedFiles,closingIssuesReferences,comments,reviews
gh pr diff <number> -R "$repo" --patch

Read the title and body before inspecting the implementation. Identify the claimed problem, expected outcome, scope, and any unstated assumptions. A missing or vague description is relevant context, but is not automatically a blocking finding.

2. Read linked issues

Use the structured closingIssuesReferences returned by the PR metadata. Read every linked issue, including its title, body, state, labels, and comments:

gh issue view <issue-url> --json number,title,url,state,labels,body,comments

A closing reference is authoritative; do not guess linked issues by grepping arbitrary #123 text in prose. If no issues are linked, report that limitation rather than inventing one.

3. Read all prior PR feedback

Read all three categories of feedback:

1. PR conversation comments (comments from gh pr view);
2. submitted reviews and their bodies (reviews from gh pr view);
3. inline review threads, including their resolved and outdated state.
