Cascade

Turn one software idea into five agent-ready markdown contracts.

One model call for product meaning; a local TypeScript compiler owns IDs, graph, files, and the five locked documents (PRD, ARD, TRD, TASKS, AGENTS) a coding agent can build from.

Semantic intake schema: features, data, integrations, constraints
Five locked presets: macOS SwiftUI desktop & menubar, Tauri 2, Astro, Android Compose
Exact-five export with SHA-256 equality between preview and export
Safe provider boundary: memory-only credentials, at most one repair request
