anti-slop

Opinionated Oxlint rules that reject low-evidence and low-signal TypeScript and JavaScript patterns.

Anti-slop is first and foremost the ruleset I use with my work, projects, and team. It reflects my preferences and taste rather than attempting to be a universal coding standard.

This project is meant to be vendored, not treated as a fixed npm dependency. There is no official npm package. Copy the rules into your repository, read them, and change them to match your team's standards. The bundled agent skill handles the initial copy and configuration; after that, the vendored files are yours to maintain and make your own. Community-maintained forks and packages are welcome, but their compatibility and release lifecycle belong to their maintainers.

Install with an agent skill

npx skills add dmmulroy/anti-slop --skill install-anti-slop

Then ask your coding agent to install or configure anti-slop in the current repository. The skill copies the plugin, installs compatible Oxlint dependencies—matching an existing Oxlint version when present—merges the plugin into the existing lint configuration, enables every generic rule, and validates the result. In repositories that depend directly on Effect, it also enables the opt-in Effect rule group.

Update an existing installation

Ask your agent to update anti-slop while preserving local customizations, optionally naming an upstream revision or selected fixes. The same skill stages incoming source separately, uses a three-way merge when the original upstream snapshot is recoverable, and otherwise ports reviewed changes conservatively. It preserves local rules and configuration, asks about conflicting policy and enabling new rules, and records provenance for future updates. It does not force-replace the vendored directory.

For latest upstream, ask the agent to retrieve and identify that revision; an already-installed skill bundle may be older. The copy script itself does not fetch or merge updates.

To inspect available skills first:

npx skills add dmmulroy/anti-slop --list

Manual local installation

Copy src/ into the target repository, for example at tools/oxlint/anti-slop/. If the repository already uses oxlint, install @oxlint/plugins at exactly the resolved Oxlint version. Otherwise, install the same current version of both packages. Keep both versions exact so upgrades move them together.

Register the copied entry point in oxlint.config.ts:

import { defineConfig } from "oxlint";
