Anti Slop
Anti Slop
A good filter for interfaces, text and code; it needs to be paired with a skill or a DESIGN.md file for design direction.
A rule set for AI agents that filters out generic interfaces, filler text and "AI-style" code; it is a filter and does not impose colors, fonts or layout.
Overview
Anti Slop (antislop) is an open-source (MIT) rule set that helps AI agents avoid delivering generic interfaces, filler wording and code with "written by AI" tells. What sets it apart from design skills: it is a filter, not a style guide, so it does not dictate colors, fonts or layout; the design direction is still yours to decide.
The author suggests using it alongside a DESIGN.md file: antislop removes what shouldn't be there (made-up figures, sparkly logos, meaningless beta labels...), while DESIGN.md provides the design direction.
There is an installer that asks you to choose skills and agents, or you can install it as a plugin for Claude Code, Codex, Cursor, Cline and many other agents.
