Tools 7 found in our last check
check_designCheck a snippet of CSS, HTML or JSX against the Slop Patterns library and return every AI design anti-pattern it matches, with the fix for each. Covers the 101 documented patterns that have a mechanical tell. Useful for reviewing generated UI code.
list_patternsList the whole Slop Patterns taxonomy: code, id, name and one-liner for every documented AI design anti-pattern.
get_patternGet one full pattern entry by id or code (e.g. "a1" or "the-unchosen-gradient"): what it looks like, why the tools produce it, who it hurts, the fix, sources.
changelogThe library version, what each release added or changed, and how patterns are versioned. Use it to cite a specific version of Slop Patterns.
search_patternsPlain-language search across the library. "gradient headline" returns A10 Gradient Text Headline.
report_patternReport an AI design anti-pattern that is NOT yet in the library, for a design failure seen repeatedly that a search of the library does not find. Reports are reviewed by a human before anything is published, and published entries credit the reporter.
whyReturn only the causal explanation for one pattern — which model, tool or template default produces it.
