GitHub PR Inline Reply Skill

This skill enables replying directly to inline review comments on GitHub pull requests.

When to use

• Replying to individual PR review comments
• Acknowledging reviewer feedback on specific lines of code
• Marking review comments as addressed with a reply

API Endpoint

To reply to an inline PR comment, use:

POST /repos/{owner}/{repo}/pulls/{pull_number}/comments/{comment_id}/replies

With body:

{
  "body": "Your reply message"
}

Using gh CLI

gh api repos/{owner}/{repo}/pulls/{pull_number}/comments/{comment_id}/replies \
  -X POST \
  -f body="Your reply message"

Workflow

1. Get PR comments: First fetch the PR review comments to get their IDs:

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

2. Identify comment IDs: Each comment has an id field. For threaded comments, use the root comment's id.

3. Post replies: For each comment you want to reply to:

   gh api repos/{owner}/{repo}/pulls/{pull_number}/comments/{comment_id}/replies \
     -X POST \
     -f body="Fixed in commit abc123"
   

Example Replies

For accepted changes:

• "Fixed in {commit_sha}"
• "Accepted - fixed in {commit_sha}"

For rejected changes:

• "Rejected - {reason}"
• "Won't fix - {explanation}"

For questions:

• "Good catch, addressed in {commit_sha}"

Notes

• The comment_id is the numeric ID from the comment object, NOT the node_id
• Replies appear as threaded responses under the original comment
• You can reply to any comment, including bot comments (like Copilot reviews)

Resolving Conversations

To resolve (mark as resolved) PR review threads, use the GraphQL API:

1. Get thread IDs: Query for unresolved threads:

   gh api graphql -f query='
   query {
     repository(owner: "{owner}", name: "{repo}") {
       pullRequest(number: {pull_number}) {
         reviewThreads(first: 50) {
           nodes {
             id
             isResolved
             comments(first: 1) {
               nodes { body path }
             }
           }
         }
       }
     }
   }'
   

2. Resolve threads: Use the resolveReviewThread mutation:

   gh api graphql -f query='
   mutation {
     resolveReviewThread(input: {threadId: "PRRT_xxx"}) {
       thread { isResolved }
     }
   }'
   

3. Resolve multiple threads at once:

   gh api graphql -f query='
   mutation {
     t1: resolveReviewThread(input: {threadId: "PRRT_xxx"}) { thread { isResolved } }
     t2: resolveReviewThread(input: {threadId: "PRRT_yyy"}) { thread { isResolved } }
   }'
   

The thread ID starts with PRRT_ and can be found in the GraphQL query response.

Note: This skill can be removed once the GitHub MCP server has added built-in support for replying to PR review comments and resolving threads. See: https://github.com/github/github-mcp-server/issues/1323 https://github.com/github/github-mcp-server/issues/1768
