gh-pr-flow

name: gh-pr-flow description: GitHub PR review workflow using GraphQL. Prefer over raw gh CLI or GitHub MCP tools when working with PR review comments and threads.

GitHub PR Review Flow

Supports standalone operations or full workflow. Ask user what they need. Default to full workflow if they share a PR URL without specifics.

Standalone Operations

Fetch PR review threads

gh api graphql -f query='{
  repository(owner: "OWNER", name: "REPO") {
    pullRequest(number: PR_NUMBER) {
      reviewThreads(first: 100) {
        nodes {
          id
          isResolved
          line
          path
          comments(first: 1) {
            nodes { id body author { login } }
          }
        }
      }
    }
  }
}' --jq '
  ["thread_id","resolved","path","line","body"],
  (.data.repository.pullRequest.reviewThreads.nodes[] | [
    .id,
    .isResolved,
    .path,
    .line,
    (.comments.nodes[0].body | gsub("\n";" ")[0:150])
  ]) | @csv'

Add select(.isResolved == false) to filter unresolved only.

Resolve a thread

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

Unresolve a thread

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

Get full thread details

gh api graphql -f query='{ node(id: "PRRT_xxx") { ... on PullRequestReviewThread { comments(first: 10) { nodes { body author { login } } } } } }'

Full Workflow

Phase 1: Setup

1.1 Identify Repository Context

Extract owner and repo from:

• PR URL provided by user (e.g., github.com/owner/repo/pull/123)
• Current git remote: git remote get-url origin
• Ask user if ambiguous

Store as variables for all subsequent calls:

OWNER=<extracted-owner>
REPO=<extracted-repo>
PR_NUMBER=<extracted-number>

1.2 Determine User Preference

Infer from context:

Hands-on (default): User wants to review changes, says "help me", "walk through", "let's look at". Confirm before executing, show diffs before commit.

Hands-off: User says "just fix", "handle it", "address all comments". Process autonomously, commit and resolve when done.

Phase 2: Retrieve Review Threads

2.1 Fetch Threads

gh api graphql -f query='{
  repository(owner: "OWNER", name: "REPO") {
    pullRequest(number: PR_NUMBER) {
      reviewThreads(first: 100) {
        nodes {
          id
          isResolved
          line
          path
          comments(first: 1) {
            nodes { id body author { login } }
          }
        }
      }
    }
  }
}' --jq '
  ["thread_id","resolved","path","line","body"],
  (.data.repository.pullRequest.reviewThreads.nodes[] | [
    .id,
    .isResolved,
    .path,
    .line,
    (.comments.nodes[0].body | gsub("\n";" ")[0:150])
  ]) | @csv'

2.2 Filter by Resolution Status

Ask user: "Show only unresolved threads, or include resolved ones too?"

For unresolved only, add to jq: select(.isResolved == false)

2.3 Present Summary

Show threads in a clear table format:

• Thread ID (for later resolution)
• File path and line number
• Resolution status
• Truncated comment preview

Phase 3: Analyze Comments

3.1 Categorize Each Thread

For each unresolved thread, categorize:

• Code change required: Bug fix, refactor, style change
• Question/clarification: Needs response, not code
• Suggestion: Optional improvement
• Nitpick: Minor issue, low priority

3.2 Fetch Full Comment When Needed

If truncated preview is insufficient, fetch full body:

gh api graphql -f query='{
  node(id: "THREAD_ID") {
    ... on PullRequestReviewThread {
      comments(first: 10) {
        nodes { body author { login } createdAt }
      }
    }
  }
}'

Phase 4: Plan Approach

4.1 Create Action Plan

For each actionable thread, determine:

• What file to modify
• What change to make
• Whether it affects other code

4.2 User Confirmation (Hands-on Mode)

If hands-on: Present the plan and ask for confirmation before proceeding.

Show:

• Files to be modified
• Summary of each change
• Any potential risks or side effects

4.3 Create Todo List

Use TodoWrite to track each thread as a task. For example:

- [ ] Fix: path/to/file.py:42 - datetime.utcnow() deprecation
- [ ] Fix: path/to/other.py:118 - error message improvement
- [ ] Respond: question about API design

Phase 5: Execute Changes

5.1 Process Each Thread

For each code-change thread:

1. Read the relevant file(s)
2. Make the fix
3. Mark todo as complete
4. Move to next thread

For question/clarification threads:

1. Note that a comment response is needed
2. Prepare response text for Phase 8

5.2 Hands-on Checkpoints

If hands-on mode: After each significant change, show diff and ask for approval.

Phase 6: Commit and Push

6.1 Stage Changes

git add -A
git status
git diff --staged

6.2 Commit

Create descriptive commit message summarizing the PR feedback addressed.

If hands-on: Show commit message and ask for confirmation.

git commit -m "Address PR review feedback: <summary>"

6.3 Push

git push

If hands-on: Ask before pushing.

Phase 7: Resolve Threads

7.1 Resolve Fixed Threads

For each thread where code was fixed:

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

7.2 Track Resolution

Report which threads were resolved and which remain open.

Phase 8: Add Comments (Optional)

8.1 Respond to Questions

If any threads required clarification responses:

gh api graphql -f query='mutation {
  addPullRequestReviewComment(input: {
    pullRequestReviewId: "REVIEW_ID",
    body: "Response text here",
    inReplyTo: "COMMENT_ID"
  }) {
    comment { id }
  }
}'

Or simpler via REST:

gh api repos/OWNER/REPO/pulls/PR_NUMBER/comments/COMMENT_ID/replies -f body="Response"

8.2 Ask User for Response Content

If user wants to add custom responses, ask what they want to say for each thread requiring a response.
