GitHub CLI

Interact with GitHub using the gh CLI tool.

PR Review Comments

Fetch a specific comment by ID

When you have a comment URL like https://github.com/owner/repo/pull/123#discussion_r2715128564, extract the comment ID from discussion_r{ID}:

gh api repos/{owner}/{repo}/pulls/comments/{comment_id}

Example:

gh api repos/biteinc/maitred/pulls/comments/2715128564

Fetch all PR inline comments

PR inline code comments (review comments) are at /pulls/{pr}/comments, NOT /pulls/{pr}/reviews:

# Get all comments with pagination
gh api "repos/{owner}/{repo}/pulls/{pr}/comments?per_page=100"

# Filter by user (e.g., CodeRabbit bot)
gh api "repos/{owner}/{repo}/pulls/{pr}/comments?per_page=100" \
  --jq '.[] | select(.user.login | contains("coderabbit"))'

# Get latest 5 comments sorted by date
gh api "repos/{owner}/{repo}/pulls/{pr}/comments?per_page=100" \
  --jq '.[] | select(.user.login | contains("coderabbit"))' \
  | jq -s '. | sort_by(.created_at) | reverse | .[0:5]'

Fetch PR review summaries

Review summaries (the top-level review with approval/request changes) are separate from inline comments:

gh api repos/{owner}/{repo}/pulls/{pr}/reviews

Key differences

Endpoint	Contains
/pulls/{pr}/comments	Inline code comments on specific lines
/pulls/{pr}/reviews	Review summaries (approve, request changes, comment)
/issues/{pr}/comments	General PR conversation comments (not on code)

Common PR Operations

# View PR details
gh pr view {pr_number} --repo {owner}/{repo}

# View PR with specific fields
gh pr view {pr_number} --repo {owner}/{repo} --json title,body,reviews,comments

# List PR files changed
gh pr diff {pr_number} --repo {owner}/{repo}

# View PR checks
gh pr checks {pr_number} --repo {owner}/{repo}

Tips

• Always use per_page=100 when fetching comments to ensure you get recent ones
• Comment IDs in URLs (#discussion_r{ID}) can be fetched directly via the API
• Use jq -s (slurp) to collect streaming JSON into an array for sorting
• CodeRabbit comments have user.login containing "coderabbit"
