name: rook-systemic-prs
description: Drive a systemic/sweeping change across the rook (github.com/rook/*) repo as a series of small, well-contained, independently reviewable PRs. Use when the user wants to run a campaign of incremental changes across the rook codebase — dead-code elimination, lint/staticcheck cleanups, API migrations, renames, import or dependency hygiene — by fanning out subagents to scan and prepare changes, excluding work already covered by open PRs, and basing everything on upstream master. Triggers include: "sweep the rook repo for X", "break this into small PRs", "dead code elimination campaign", "iteratively clean up rook", "find another N PRs worth of <change>".

# Rook systemic change → small PRs

A repeatable loop for applying a *systemic* change (one rule applied in many
places) to a `github.com/rook/*` repo, delivered as many **small, isolated,
independently mergeable PRs** instead of one mega-PR. Optimized for **aggressive
