Review PRs created by the agent cop fix workflow and approve, fix, or close them.
Fix variant (EnforcedStyle) FP/FN on a cop — either a CI regression on a bot PR, or outstanding divergence from the corpus oracle. Auto-reads docs/corpus.md for examples.
Get a department or gem all the way to 100% conformance using per-cop validation and generated corpus reports, never manual README/docs edits.

When adding a new rubocop plugin gem or updating an existing gem version, the following files must be updated. Use this checklist to ensure nothing is missed.
bench/corpus/GemfilePin the gem version (e.g. gem "rubocop-rake", "0.7.1").
bench/corpus/diff_results.pyAdd or update the gem version in the "baseline" dictionary inside write_corpus_results().
bench/corpus/baseline_rubocop.ymlAdd the gem to the plugins: list. If any cops are Enabled: false in the gem's vendor default config, add explicit Enabled: true overrides (see existing examples for RSpec, Rails, etc.). Cops that default to Enabled: true or Enabled: pending don't need overrides — NewCops: enable handles pending cops.
bench/corpus/update_readme.pyAdd an entry to the GEMS list with key, url, and departments.
scripts/dispatch_cops.pyAdd the department to DEPT_TO_VENDOR (maps department name to vendor/<gem-dir>). If the department name doesn't snake_case cleanly (e.g. FactoryBot -> factory_bot, RSpecRails -> rspec_rails), also add it to DEPT_TO_DIR and DEPT_TO_SRC_DIR.
.github/workflows/batch-dispatch.ymlAdd the department to the department choice options list (keep alphabetical order).
Add the vendor submodule pinned to the release tag: git submodule add <repo-url> vendor/<gem-name>.
New cops default to preview tier via src/resources/tiers.json. Promotion to stable happens automatically via the corpus oracle workflow — do not manually edit tiers.json. The corpus oracle uses --preview so preview-tier cops are always tested in CI, but users running nitrocop locally without --preview won't see them.
See PR #1353 (rubocop-rake support) for an example of adding a new plugin gem, though note it missed several of the items in this checklist (fixed in a follow-up commit).
