Generate pure CSS masonry-style layouts with responsive breakpoints, configurable gaps, and optional full-width skip selectors

Mutate OpenAPI request fields into semantically risky variants and optionally send them to a real backend to check defensive validation coverage

Simulate the reading order and spoken semantics a screen reader may expose from a URL or raw HTML, then flag likely accessibility gaps

Generate a contrast-focused accessibility heatmap from a UI screenshot or HTML input and suggest stronger patch colors

Validate a real API response JSON against the response schema declared in an OpenAPI 3.x specification

Parse Terraform plan JSON or text output, classify resource changes, and surface a dependency-oriented summary before apply

Expand RRULE-based VEVENT recurrence into concrete occurrences and export them as JSON or a flattened ICS calendar

Forecast future periods from CSV or JSON time-series data and inspect trend, seasonal, and residual decomposition in one report
