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.

Check if a failing test is a known upstream flake in Chromium's LUCI Analysis database. Provides flakiness statistics, verdict, and recommendation for filter file decisions. Triggers on: check upstream flake, is this test flaky upstream, check luci flakiness, upstream flake check.

Delete local branches whose PRs have been merged upstream. Checks GitHub PR status for each branch. Triggers on: clean branches, delete merged branches, prune branches, branch cleanup.

Audit and fix best practices docs for stale references, duplicates, obsolete content, and formatting issues. Triggers on: fix bp docs, fix best practice docs, audit bp docs.

Force-push a branch and all its downstream branches to origin. Auto-detects the downstream tree and skips branches already up-to-date. Triggers on: force push downstream, push chain, push all branches.

Implement review feedback on a PR. Checks out the branch, applies reviewer-requested changes, runs preflight, commits, and pushes. Triggers on: impl-review, implement review, implement review feedback, address review comments.

Re-run failed CI jobs for a brave/brave-core PR. Detects failure stage and uses WIPE_WORKSPACE for build/infra failures. Triggers on: make ci green, retry ci, rerun ci, fix ci, re-run failed jobs, retrigger ci.
