Check PR

Do one pass over PR $ARGUMENTS: check CI, read reviews, fix what's actionable, report status.

1. Gather PR state

# Overall state
gh pr view $ARGUMENTS --repo docker/docs --json state,title,url,headRefName

# CI checks
gh pr checks $ARGUMENTS --repo docker/docs --json name,state,detailsUrl

# Top-level reviews
gh pr view $ARGUMENTS --repo docker/docs --json reviews,reviewDecision

# Inline (line-level) comments — NOT included in the above
gh api repos/docker/docs/pulls/$ARGUMENTS/comments \
  --jq '[.[] | {id: .id, author: .user.login, body: .body, path: .path, line: .line}]'

Always check both the reviews endpoint and the inline comments endpoint. A review with an empty body may still have line-level comments requiring action.

2. If merged

Report the final state. Then check for any unanswered review comments (both top-level and inline) and reply to each one explaining what was done or that the issue was addressed in a follow-up. Skip to step 6 after.

3. If closed without merge

Read the closing context to understand why:

gh pr view $ARGUMENTS --repo docker/docs --json closedAt,comments \
  --jq '{closedAt, lastComment: .comments[-1].body}'

Report the reason. Common causes: rejected by maintainers, superseded by another PR, closed by automation.

4. If CI is failing

• Read the failure details (follow detailsUrl if needed)
• Determine if the failure is in the PR's changed files or pre-existing
• Actionable: check out the branch, fix, commit, push

  git checkout <branch>
  # fix the issue
  git add <files>
  git commit -m "fix: <description>"
  git push

• Pre-existing / upstream: note it, do not block

5. If review comments or changes requested

• Read each unresolved comment
• Address feedback in a follow-up commit
• Push, then reply to each comment explaining what was done:

  gh api repos/docker/docs/pulls/$ARGUMENTS/comments \
    --method POST \
    --field in_reply_to=<comment-id> \
    --field body="<response>"

• End every comment reply with an accurate agent-disclosure footer that names the active coding agent, for example Generated by Codex or Generated by Claude Code.
• Resolve each thread via GraphQL after replying:

  # Get thread IDs
  gh api graphql -f query='
    query($owner:String!, $repo:String!, $pr:Int!) {
      repository(owner:$owner, name:$repo) {
        pullRequest(number:$pr) {
          reviewThreads(first:50) {
            nodes { id isResolved comments(first:1) { nodes { path } } }
          }
        }
      }
    }' -f owner=docker -f repo=docs -F pr=$ARGUMENTS \
    --jq '.data.repository.pullRequest.reviewThreads.nodes[] | select(.isResolved == false) | {id, path: .comments.nodes[0].path}'
  
  # Resolve a thread
  gh api graphql -f query='
    mutation($id:ID!) { resolveReviewThread(input:{threadId:$id}) { thread { isResolved } } }
  ' -f id=<thread-id>

• Re-request review if changes were requested
