PR All Repos

Create pull requests across all sub-repos that have branches ready for review, then cross-link them as sibling PRs.

Prerequisites

• gh CLI must be authenticated (gh auth status)
• Each sub-repo must have a remote configured

Order of Operations

1. Scan — identify repos with PR-ready branches
2. Create PRs — open a PR in each qualifying repo
3. Cross-link — update each PR description with sibling PR URLs

Step 1: Scan

For each directory in repos/*/ that is a git repository:

1. Check the current branch: git -C repos/<name> branch --show-current
2. Skip if on the default branch (main/master) — nothing to PR
3. Check if a PR already exists for this branch: gh pr view --repo <remote> --json url 2>/dev/null
4. Skip if a PR already exists — but record its URL for cross-linking
5. Check if the branch has been pushed: git -C repos/<name> log @{u}..HEAD 2>/dev/null
6. If unpushed commits exist, push first: git -C repos/<name> push -u origin <branch>

Collect the list of repos that need new PRs and repos that already have PRs.

Step 2: Create PRs

For each repo that needs a new PR:

1. cd into the repo directory
2. Read git log --oneline main..<branch> (or master) to understand the changes
3. Draft a PR title (short, under 70 characters) and body
4. Create the PR:

gh pr create --title "<title>" --body "$(cat <<'EOF'
## Summary
<bullet points describing changes>

## Sibling PRs
<!-- Will be updated with cross-links -->

## Test Plan

5. Record the PR URL

Step 3: Cross-Link

After all PRs are created (or found existing), do a second pass:

For each PR (new and existing), update its description to include a "Sibling PRs" section listing all other PRs in this batch:

## Sibling PRs
- [frontend#42](https://github.com/org/frontend/pull/42) — Update auth UI components
- [infra#18](https://github.com/org/infra/pull/18) — Add new IAM role for auth service

Use gh pr edit <number> --repo <remote> --body "<updated body>" to update descriptions.

Branch Name Convention

If all repos share the same branch name (e.g., feature/ENG-123-auth-redesign), note the ticket ID in the summary. If branch names differ across repos, still link them — the sibling PR section is the coordination mechanism.

Arguments

The user may optionally specify:

• A base branch: /pr-all-repos --base develop (default: main)
• A subset of repos: /pr-all-repos frontend backend-api (default: all repos with non-default branches)

Summary

Report a table at the end:

Repo	PR	Status
frontend	#42	Created
backend-api	#15	Already existed — updated with sibling links
infra	—	Skipped (on main)

Notes

• Never force-push
• If gh is not authenticated, inform the user and stop
• If a repo has no remote, skip it with a warning
• Preserve any existing PR description content when adding sibling links — only add/update the "Sibling PRs" section
