Use when designing, writing, or reviewing backend code — HTTP endpoints, payment or state-changing flows, database reads and writes, calls to other services, background jobs, rolling out a risky change, or production alerting and on-call.

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

# Clean Backend

The operational habits that don't surface from inside the code in front of you.

Every practice here was measured missing from real baseline output. The practices
that showed up reliably without prompting were removed — see *Deliberately not
covered* at the end. Apply these **in addition to** your own engineering judgment;
they are a floor to add, not a checklist that replaces what you already do well.

## Part 1 — Absent from every baseline

Three lifecycle decisions. Nothing inside a single endpoint cues them, which is
exactly why they get skipped.

### 1. Version the route from day one

```TypeScript
// Measured: the route ships unversioned, every time.
POST /charges
GET  /products

// Fill the version slot.
POST /api/v1/charges
GET  /api/v1/products
```

Mobile clients outlive your refactors. An unversioned route turns the first
breaking change into a coordinated migration.

**Skip it when** the service has exactly one consumer that you deploy atomically
with it.

### 2. Deploying is not releasing

```TypeScript
// Measured: the new path ships live to everyone at once.
return renderCheckoutV2(cart);
…

How to install

The exact contents, by fingerprint

mdr add allanops/clean-backend/clean-backend@sha256:24f38972b52d9f61

The line at the top of this page pins the label git:20260723.9cc7cc7, 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.
