dtsong/GitHub PR Request Review

Scope Constraints

• Read-write operations — requests reviewers and teams for a pull request.
• Reads CODEOWNERS, file history, and team assignments to suggest reviewers.
• Does not approve or submit reviews — reviewers do that themselves.
• Does not merge PRs — use gh-pr-merge skill for that.

Input Sanitization

• PR numbers: must be positive integers.
• Reviewer usernames: alphanumeric characters and hyphens only; must begin with @ prefix.
• Team names: alphanumeric characters, hyphens, and forward slashes only (e.g., team/frontend).
• Repository identifier: inferred from local git context; if provided, must match owner/repo format with alphanumeric characters and hyphens only.

/gh-pr-request - Request PR Reviewers

Request reviewers for a pull request with smart suggestions.

Usage

/gh-pr-request                    # Suggest reviewers for current PR
/gh-pr-request @user1 @user2      # Request specific reviewers
/gh-pr-request 123 @user1         # Request reviewer for PR #123
/gh-pr-request --team backend     # Request team review

Workflow

Step 1: Identify PR

# Get PR for current branch
PR_NUM=$(gh pr view --json number -q '.number' 2>/dev/null)

if [ -z "$PR_NUM" ]; then
    echo "No PR found for current branch."
    echo "Create one with: /commit-push-pr"
    exit 1
fi

Step 2: Analyze Changed Files

# Get files changed in PR
gh pr view $PR_NUM --json files -q '.files[].path'

# Identify code owners
# Check CODEOWNERS file if exists
cat .github/CODEOWNERS 2>/dev/null

Step 3: Suggest Reviewers

Based on:

• CODEOWNERS rules
• Recent contributors to changed files
• Team assignments
• Past reviewers on similar changes

# Get recent contributors to changed files
for file in $(gh pr view $PR_NUM --json files -q '.files[].path'); do
    git log --format='%an' -n 5 -- "$file"
done | sort | uniq -c | sort -rn

Step 4: Request Reviewers

# Request individual reviewers
gh pr edit $PR_NUM --add-reviewer @user1,@user2

# Request team review
gh pr edit $PR_NUM --add-reviewer team/backend
