greenfield-architect skillA

greenfield-architect is agent-read markdown (skill) from jdanigo/hydraia: Use when the user wants a new app, service, or system designed from scratch — greenfield work with no existing code to anchor to. Interactive architect: elicits requirements one question at a time, drives architecture proposals, recommends a stack with rationale, designs the API contract, and records every decision as an ADR. Never assumes scale, stack, or constraints..

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

Latest version
mdr add jdanigo/hydraia/greenfield-architect@git:20260703.c5a2b92
Exact content
mdr add jdanigo/hydraia/greenfield-architect@sha256:5c7b3b18e24c8b93

Pin 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.
