Plan a new frontend project or first vertical slice from a product idea, with approval gates before scaffolding. Excludes existing-project micro-fixes, automatic scaffolds, package installation, UI libraries, and test setup.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Greenfield Project Builder ## Purpose Plan and execute the first safe steps of a new frontend project without turning a vague product idea into uncontrolled scaffolding. This skill converts a product idea into a minimal frontend project plan, explicit stack assumptions, approval gates, first vertical slice, and onboarding handoff. It must not scaffold, install packages, or create application files unless the user explicitly approves the exact action. ## When To Use Use this skill only for `Deep Workflow` tasks. Use this skill when the user asks to: - start a new frontend project; - plan a new frontend app from a product idea; - create a project structure before scaffolding; - define the first vertical slice of a new app; - choose an intended frontend stack before project creation; - prepare onboarding overlays for an empty or new project; - turn a broad product concept into a small frontend implementation path. ## When Not To Use Do not use this skill for: - existing-project bugfixes; - one route or component in an existing project; - purely visual redesign of an existing screen; - refactoring existing code; - UI component library setup; - testing workflows; …

How to install
mdr add ytvee-dev/webdev-agent-kit/greenfield-project-builder@sha256:7351cff3009c9b3aThe line at the top of this page pins the label git:20260710.89f880b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
