Create PR

Create a GitHub pull request from the current branch with an auto-generated title and description based on commit history.

Usage

/pr-create [--target <branch>] [--draft] [--title "<title>"]

Flag	Description
`--target <branch>`	Target branch (default: repository's default branch)
`--draft`	Create as a draft PR
`--title "<title>"`	Override the auto-generated title

Prerequisites

Must be inside a git repository with a GitHub remote
The gh CLI must be installed and authenticated (gh auth status)

Workflow

Step 1: Gather Branch Information

Get the current branch and verify it has commits to push:

git branch --show-current

If on main or master, warn the user — they probably want to create a feature branch first.

Check if the branch has been pushed to the remote:

git log --oneline origin/{branch}..HEAD 2>/dev/null

If there are unpushed commits, push the branch first:

git push -u origin {branch}

Ask the user for confirmation before pushing.

Step 2: Determine Target Branch

If --target was specified, use that branch.

Otherwise, determine the default branch:

gh repo view --json defaultBranchRef --jq '.defaultBranchRef.name'

Step 3: Check for Existing PR

Check if a PR already exists for this source → target branch combination:

gh pr list --head {branch} --json number,url

If one exists, show the URL and ask the user if they want to update that PR instead of creating a new one.

Step 4: Generate Title and Description

If --title was specified, use that.

Otherwise, generate a title from the commit history:

git log --oneline origin/{target}..HEAD

Title rules:

If there's 1 commit, use the commit message as the title.
If there are 2-5 commits, summarize the overall change in one line (under 70 chars).
If there are 6+ commits, summarize the theme of the changes.

Description: Generate a markdown summary:

## Summary

{2-3 bullet points summarizing what this PR does, derived from commit messages and changed files}

## Changes

{list of commits, from `git log --oneline`}

## Files Changed

{output of `git diff --stat origin/{target}..HEAD`}

If commit messages or the branch name reference issues (e.g., fix-123, Fixes #456), include Fixes #<number> in the description body to auto-link.

Step 5: Confirm with User

Before creating the PR, show the user what will be created:

## PR Preview

**Title:** {title}
**Source:** {branch} → **Target:** {target}
**Draft:** {yes/no}

### Description
{description}

Use AskUserQuestion to confirm:

Create — proceed as shown
Edit — let the user modify title/description
Cancel — abort

Step 6: Create the PR

gh pr create --title "{title}" --body "{description}" --base {target} [--draft]

Step 7: Confirm

After creation, show:

## PR Created

**PR #{number}:** {title}
**URL:** {url}

Error Handling

gh not authenticated: Suggest running gh auth login.
Not in a git repo: Tell the user to navigate to a repository.
No commits ahead of target: Nothing to create a PR for. Tell the user.
Branch already has a PR: Warn if one exists and offer to update instead.
Push fails: Remote rejection, authentication issues — show the error and suggest fixes.

Safety

Always confirm before pushing — the user may have unpushed commits they're not ready to share.
Always preview before creating — show the full PR preview and let the user edit or cancel.
Do NOT create PRs without user confirmation.
Do NOT push to protected branches (main, master, release/*).
