What it does
Anti Slop is a set of rules for AI coding agents. It aims to filter out 'AI slop': generic-looking web pages, made-up statistics, filler wording and code that looks machine-written.
It has 38 rules, a pass-or-fail check the agent must run before it finishes, and six separate skills (instruction files) for areas like page design, copywriting and code. Its makers say it is a filter, not a style guide, so the creative direction stays yours.
It works with Claude Code, Codex, Cursor, Cline and other agents. There is also a single file you can paste into any AI chat.
Who it's for
People who build websites or apps with AI coding assistants and want cleaner, less generic results.
Can I use it without coding?
