Fetch Pr Comments

Fetch PR Comments

Fetch all comments from a GitHub pull request, filtered to trusted users only. Trusted users are GitHub org members and explicitly allowed bots. Untrusted comments are silently excluded.

This skill fetches from all three GitHub comment endpoints (inline review comments, review summaries, and PR conversation comments), providing a complete picture of PR feedback.

When to Use This Skill

Use this skill when you need to:

• Check a PR for new review comments that need attention
• Monitor a PR for feedback during an agentic workflow
• Build a review-response loop that only processes trusted feedback
• Fetch all actionable PR comments in a single call

Prerequisites

1. gh CLI: Authenticated with gh auth login
2. Repository read access: The token must have permission to read PR comments and check org membership

Implementation

Basic usage

result=$(bash "${CLAUDE_PLUGIN_ROOT}/skills/fetch-pr-comments/fetch_pr_comments.sh" \
  --repo owner/repo \
  --pr 123)

With custom trusted bots and exclusions

result=$(bash "${CLAUDE_PLUGIN_ROOT}/skills/fetch-pr-comments/fetch_pr_comments.sh" \
  --repo owner/repo \
  --pr 123 \
  --trusted-bots "coderabbitai,dependabot" \
  --exclude-ids "12345,67890")

Parameters

Output

JSON on stdout:

{
  "inline_comments": [
    {"id": "123", "user": "reviewer", "path": "pkg/server.go", "body": "This needs a nil check"}
  ],
  "reviews": [
    {"id": "456", "user": "reviewer", "state": "CHANGES_REQUESTED", "body": "See inline comments"}
  ],
  "issue_comments": [
    {"id": "789", "user": "coderabbitai[bot]", "body": "Static analysis found..."}
  ],
  "all_ids": ["123", "456", "789"],
  "total": 3,
  "formatted": {
    "inline": "**reviewer** on `pkg/server.go`:\nThis needs a nil check\n---",
    "reviews": "**reviewer** (CHANGES_REQUESTED):\nSee inline comments\n---",
    "issue_comments": "**coderabbitai[bot]**:\nStatic analysis found...\n---"
  }
}

Using in a polling loop

The all_ids and --exclude-ids fields enable stateful polling across iterations:

PROCESSED_IDS=""

while true; do
  sleep 300

  result=$(bash "${CLAUDE_PLUGIN_ROOT}/skills/fetch-pr-comments/fetch_pr_comments.sh" \
    --repo owner/repo --pr 123 --exclude-ids "$PROCESSED_IDS")

  total=$(echo "$result" | jq -r '.total')
  if [[ "$total" -gt 0 ]]; then
    # Process comments...
    new_ids=$(echo "$result" | jq -r '.all_ids | join(",")')
    PROCESSED_IDS="${PROCESSED_IDS:+$PROCESSED_IDS,}$new_ids"
  fi
done

Using formatted output for Claude prompts

The formatted fields provide ready-to-use text:

inline=$(echo "$result" | jq -r '.formatted.inline')
reviews=$(echo "$result" | jq -r '.formatted.reviews')
issue_comments=$(echo "$result" | jq -r '.formatted.issue_comments')

How It Works

1. Fetches from three GitHub API endpoints:
   • repos/{repo}/pulls/{pr}/comments — inline code review comments
   • repos/{repo}/pulls/{pr}/reviews — review summaries (CHANGES_REQUESTED, etc.)
   • repos/{repo}/issues/{pr}/comments — PR conversation thread
2. Identifies all unique comment authors
3. Checks each author against the trusted bots list and org membership (gh api orgs/{org}/members/{login})
4. Filters comments to trusted authors only
5. Excludes already-processed comment IDs
6. Filters out APPROVED and PENDING reviews (no actionable content)
7. Returns structured JSON with both raw data and pre-formatted text

Trust Model

A user is trusted if they match ANY of:

• Their login matches a --trusted-bots entry (with or without [bot] suffix)
• They are a member of the repository's GitHub organization

All other commenters are silently excluded.
