PR Comment Fix Workflow

Checkout a PR branch, fetch unresolved review comments, fix each one, commit, reply, resolve, and push — all in one pass.

Prerequisites

Before starting, verify gh is authenticated:

gh auth status

If it fails, stop and tell the user to run gh auth login.

Step 1: Identify the PR

Determine the target PR from the user's message. They might give you a PR number (#142), a branch name (feature/new-parser), or a URL. Normalize to a PR number early:

# If given a branch name, find its open PR
gh pr list --head <branch-name> --state open --json number --jq '.[0].number'

Once you have the PR number, fetch the branch name and check it out:

gh pr checkout <pr-number>

This ensures you're on the exact branch the PR tracks — not a stale local copy.

Step 2: Fetch unresolved review comments

Pull all review comments and filter to unresolved threads. Each comment has a thread ID, file path, line number, and body.

gh api graphql -f query='
  query($owner: String!, $repo: String!, $pr: Int!) {
    repository(owner: $owner, name: $repo) {
      pullRequest(number: $pr) {
        reviewThreads(first: 100) {
          nodes {
            id
            isResolved
            comments(first: 10) {
              nodes {
                body
                path
                line
                author { login }
              }
            }
          }
        }
      }
    }
  }
' -f owner='{owner}' -f repo='{repo}' -F pr=<pr-number>

Extract {owner} and {repo} from the current git remote:

gh repo view --json owner,name --jq '"\(.owner.login) \(.name)"'

Filter to threads where isResolved is false. If every thread is already resolved, tell the user there's nothing to fix and stop.

Step 3: Triage comments

Not every comment is actionable code feedback. Classify each unresolved thread:

• Actionable — requests a concrete code change (rename, refactor, fix bug, add validation, change logic, etc.)
• Question / Discussion — asks "why did you do X?" or debates an approach with no clear fix directive
• Nit / Style — trivial formatting or naming preferences
• Praise / Acknowledgement — compliments, thumbs-up, "looks good"
