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.

Auto-detect top maintainers for each repo in an org and set the maintainers custom property via the GitHub API. Use when the user wants to populate or update maintainer metadata.

Validate metadata fields (author, source, category) in opengrep/semgrep YAML rule files. Use when the user wants to lint or check rule quality.

Clean up stale security-action Slack messages based on review signals (reactions, label removal, resolved threads). Use when the user wants to clean old notifications from a Slack channel.

Delete Slack messages from a channel filtered by bot username and repository names. Use when the user wants to bulk-delete bot messages for specific repos.

Auto-dismiss Dependabot alerts matching configurable hotwords (e.g. DoS) or a GHSA/CVE dismiss list. Use when the user wants to bulk-dismiss low-priority Dependabot alerts.

Scan org repos for open Dependabot alerts at or above a severity threshold and build notification messages for maintainers. Use when the user wants to check or nudge about Dependabot vulnerabilities.

Fetch and parse a JSON config file from a GitHub repository. Use when the user wants to read a configuration file from a remote repo.

List all repositories in a GitHub org with their maintainers custom property. Use when the user wants to see who maintains each repo.
