GitHub PR Manager#

Overview#

Streamline GitHub Pull Request workflows: create, review, merge, changelog generation, CI checks, and draft management via gh CLI. Use when Codex needs to manage PR lifecycle, check review status, handle merge conflicts, or generate changelogs.

Quick Start#

Prerequisites#

• gh CLI installed and authenticated ( gh auth status)
• Git repository with remote on GitHub

Check your PR overview#

bash

bash scripts/gh-pr-review.sh --mine

Create a PR with auto-generated content#

bash

python3 scripts/gh-pr-create.py --draft --label review-needed

Generate changelog from merged PRs#

bash

python3 scripts/gh-pr-changelog.py --from v1.0 --to v2.0

Common Tasks#

Creating & managing PRs#

bash

# Create draft PR
gh pr create --draft --title "WIP: Add login" --body "In progress"

# Create PR with labels
gh pr create --label enhancement --label needs-review

# View PR details
gh pr view <number>         # view in terminal
gh pr view <number> --web   # open in browser

# Update PR
gh pr edit <number> --title "New title" --add-label ready

Review workflow#

bash

# Check what needs my review
gh pr list --search "review-required:@me" --state open

# Approve
gh pr review <number> --approve --body "LGTM"

# Request changes
gh pr review <number> --request-changes --body "Please fix the tests"

# Add comment
gh pr review <number> --comment --body "Nice work!"

# Check review status on a PR
gh pr view <number> --json reviewDecision,reviews

CI & merge#

bash

# Check CI status
gh pr checks <number>            # detailed status
gh pr view <number> --json statusCheckRollup

# Merge when checks pass
gh pr merge <number> --squash    # squash and merge
gh pr merge <number> --rebase    # rebase and merge
gh pr merge <number> --merge     # merge commit
gh pr merge <number> --auto      # auto-merge after checks pass

# Check mergeability
gh pr view <number> --json mergeable,mergeStateStatus

Conflict resolution#

bash

# Check if PR has conflicts
gh pr view 42 --json mergeable
# → "CONFLICTING" if there are conflicts

# Fix locally
git checkout <pr-branch>
git fetch origin
git merge origin/main                # resolve conflicts
git push

# Alternative: rebase instead
git rebase origin/main               # resolve conflicts
git push --force-with-lease

Working with branches#

bash

# Checkout a PR locally for testing
gh pr checkout <number>

# List your branches with PR status
gh pr list --author "@me" --json headRefName,title,state,isDraft

# Compare branches
gh pr diff <number>              # view diff
gh pr diff <number> --name-only  # just filenames
