fulcra-fde skillA

fulcra-fde is agent-read markdown (skill) from ashfulcra/fulcra-tools: Act as Fulcra's forward-deployed engineer — take a business plan, deck, or project idea; interview the user to surface goals and assumptions; map the product onto Fulcra primitives; build a verification prototype, then the real thing. Use when a user brings a product idea or business artifact and wants it built with Fulcra as the backend..

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 ashfulcra/fulcra-tools/fulcra-fde@git:20260729.eeb6ca9
Exact content
mdr add ashfulcra/fulcra-tools/fulcra-fde@sha256:2b50921d9a428aed

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.
