Create a standalone Architecture Decision Record (ADR) for a single significant architectural decision. Captures context, decision, alternatives considered, and consequences. ADRs are immutable - once accepted, they are never edited, only superseded by a new ADR.
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
## Purpose Produce a single ADR that permanently captures a significant architectural decision. ADRs are append-only: once `Accepted`, they are never edited. If a decision is reversed, a new ADR is written with `Supersedes: ADR-NNN`. ## Input **Works best with:** A clear description of the decision being recorded. **Also valuable:** The context that led to the decision, the alternatives that were considered, any benchmarks or evidence, and the known trade-offs. **Example invocation:** `Document our decision to use HMAC-SHA256 request signing for webhook delivery instead of bearer tokens. We chose this because webhooks are server-to-server calls where rotating tokens is operationally complex, while HMAC signing uses a per-merchant secret and validates the payload integrity simultaneously.` ## Key Concepts ### ADR Lifecycle ``` Proposed → Accepted → (Deprecated) → (Superseded by ADR-NNN) ``` - **Proposed:** Under discussion. May still change. - **Accepted:** Binding. Implementation should follow this decision. - **Deprecated:** The decision is outdated but not actively reversed. - **Superseded:** A newer ADR (referenced) replaces this one. ### What Qualifies as an ADR …

How to install
mdr add fattain-naime/engineering-docs/architecture-decision-record@sha256:e438472cbe066bbbThe line at the top of this page pins the label git:20260717.2f82174, 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.
