mvp-creator skillA
mvp-creator is agent-read markdown (skill) from maquina-app/rails-claude-code: Create comprehensive MVP documentation for Rails applications. Use this skill whenever a user describes a new app idea, wants to explore a SaaS concept, needs competitor research, or is starting a new project from scratch — even if they don't explicitly say "MVP". Triggers on "I have an idea for...", "I want to build...", "help me plan...", "research competitors for...", "create a business plan for...", "design a brand for my app", "set up Claude for my Rails project", "bootstrap an app", or any.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
How to install
mdr add maquina-app/rails-claude-code/mvp-creator@git:20260714.7bc748dmdr add maquina-app/rails-claude-code/mvp-creator@sha256:a1dba6bf97fe116aPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
