Analyzes routes, components, state, APIs, and interactions to generate
complete Product Requirements Documents. Framework-agnostic (React, Vue,
Angular, Svelte, Next.js, Nuxt). Three-phase workflow: global scan,
page-by-page deep analysis, structured doc generation.
Inspired by community contribution (PR #368) but rebuilt from scratch
in English with enhanced coverage for mock API detection, field
interdependencies, and execution pacing strategies.
