Evil Martians' "ten anti-AI-slop moves" as a package: strict tsconfig base (noUncheckedIndexedAccess, exactOptionalPropertyTypes), type-checked typescript-eslint strict+stylistic, unicorn/sonarjs/perfectionist, behaviour rules for tests (expect-expect, no-focused-tests), React (hooks, @eslint-react, jsx-a11y strict, you-might-not-need-an-effect), Playwright, and layer boundaries via eslint-plugin-boundaries 7 with the article's default policies. Knip / jscpd / Stryker bases; Stryker carries no break threshold on purpose. Plugins are dependencies, not devDependencies: a flat config imports them from this package's own node_modules, so a consumer installing from the git tag gets them or the lint cannot run. No build step, so the tag needs no prepare. test/fixture is a mini repo with one planted violation per rule family; test/expected.js names the rule that must catch each, and the suite runs the real CLI over it (in a child process -- v8 coverage merges natively-loaded and transformed copies of the same module into "uncovered"). 35 tests, 100% branch coverage on the factories. eslint/fast.js is the type-free subset for a per-edit hook: 0.52 s cold on one file, measured against 1.28 s for base() without types -- importing a plugin is the cost, so it loads none, nor base.js which imports them. Probed under ESLint 10: jsx-a11y 6.10.2 (peer says <=9) and boundaries 7.2.0 both run; the fixture pins that.
