Clean up local branches by checking their GitHub PR status and deleting those that have been merged.
master:git fetch origin master
git branch --format='%(refname:short)' | grep -v '^master$'
Show the list to the user. If no branches exist besides master, report that
and stop.
Method 1: Direct ancestry — Catches regular merges and fast-forwards:
git branch --merged origin/master --format='%(refname:short)'
Method 2: Squash merge detection via git cherry — For branches not caught
by method 1, check if all commits have equivalent patches in origin/master. A
- prefix means the patch already exists upstream:
git cherry -v origin/master <branch>
If ALL lines start with - (or output is empty), the branch has been
squash-merged.
Method 3: GitHub PR status (if gh is authenticated) — For remaining
branches:
# Check for merged PRs
gh pr list --head <branch> --state merged --json number,title,url
# Check for closed (not merged) PRs
gh pr list --head <branch> --state closed --json number,title,url,mergedAt
A PR is "closed without merge" when it appears in the closed list but has an
empty/null mergedAt field. If gh is not authenticated, skip this method.
Important: Always compare against origin/master (not local master) to
detect merges even when local master is stale.
Categorize branches into these groups:
Display categorized list — Show the user a summary table with:
Confirm with user — Ask the user which branches to delete:
Delete confirmed branches — If currently on a branch being deleted,
switch to master first and fast-forward it:
git checkout master && git merge --ff-only origin/master
git branch -D <branch1> <branch2> ...
After deleting, prune stale remote tracking references:
git remote prune origin
Create a Plaster (`rewrite/*.yaml`) config for an existing Brave-core Chromium `.patch`, authoring an intent-conveying regex match per the Plaster Dos and Don'ts, then verifying it by running `plaster.py apply` and diffing the regenerated patch against the original. Does not modify sources or create other files. Triggers on: plaster from patch, convert patch to plaster, plasterize, make a plaster.
For an external contributor's open PRs to brave/brave-core, ensure the `sync-and-rebase-pr-from-fork.yml` workflow has been dispatched for each PR's latest commit SHA — so a `contributor-*` draft PR exists inside brave/brave-core and CI can run. Invoke when the user says something like "create contributor PRs for <user>", "sync contributor PRs <list>", "run the rebase-from-fork workflow for these PRs", or passes a GitHub username / list of PR URLs/numbers.
Add a new best practice to the appropriate doc. Checks for duplicates, assigns stable IDs, creates new category docs if needed. Triggers on: add best practice, new best practice, add bp, new bp.
"Create an uplift PR that cherry-picks merged PRs from a contributor into a target branch (beta or release). Defaults to broad eligibility; the scope can be narrowed via a free-form description (e.g. 'only automated test and crash fixes'). Triggers on: /uplift, create uplift, uplift PRs."
Review PRs in the configured PR repository for best practices violations. Supports single PR (#12345), state filter (open/closed/all), and auto mode for cron. Triggers on: review prs, review recent prs, /review-prs, check prs for best practices.
Run all preflight checks (format, gn_check, presubmit, build, tests) to make sure the current work is ready for review.
