Build and customize a production-ready agent workflow from scratch, or audit and upgrade an existing repo — decision-complete tickets with success criteria bound to red oracles, a hook-enforced gate, a definition of done and of a bug, adversarial review that executes, and runtime proof against the real system.
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 — stand up the agentic-project success harness Install the planning and guardrail harness that keeps an agentic coding project correct and resumable, into a target repo — empty (**init**) or existing (**audit**). Lead with the principles; derive the concrete artifacts at runtime to fit the project's stack. **On invocation, go straight to Process step 1:** print the fixed summary below verbatim as plain text, then ask init vs audit and begin the interview. Do not inspect the working directory to guess the mode — ask the user. Running `/greenfield` is the instruction — do not wait for further direction. Premise under everything: **agent-written code is first-class**. It meets the same bar as hand-written code, so the project needs guardrails that keep agent work correct, verifiable, resumable, and consistent — not a lighter standard because "an agent wrote it." Two rules govern this skill: - **Full kit, adaptive form.** Every one of the 17 success factors below is secured by *some* artifact in every project — except factor 17 (performance), whose artifact is present only where the project has a perf-sensitive surface, else a justified N/A. Each artifact's …

How to install
mdr add davidegreenwald/claude-greenfield/greenfield@sha256:14710335efb476b2The line at the top of this page pins the label git:20260906.f56f45e, 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.
