Engineering criteria for implementation: SOLID, Clean Code, patterns, comment anchors, quality signals and simplification-first debt.

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

# Implementation standards

> Load this skill before writing or reviewing code. It is the **source of engineering criteria**;
> `.atlas/agents/engineer.md` is only a summary.

---

## SOLID

- **S** — one reason to change per class; one use case per application service.
- **O** — extend through composition, polymorphism and dependency injection before inheritance.
- **L** — subtypes must be substitutable without breaking invariants; prefer composition.
- **I** — keep interfaces small and specific to their consumer; no god interfaces.
- **D** — dependencies point toward the domain; high-level modules do not depend on low-level ones.
- Supporting concepts: cohesion, low coupling, encapsulation.

## Design patterns

- Apply them **only when the problem justifies it** and they reduce complexity.
- Premature abstraction is debt, just like duplication.
- Common: Factory, Strategy, Repository, Specification, Observer, Builder.

## Clean Code

- Meaningful names that reveal intent; no cryptic abbreviations.
- Small functions that do one thing.
- No dead, commented-out or unrefactored code.
- DRY with judgment: do not abstract for the sake of abstracting.

## Comment anchor (mandatory)

How to install

The exact contents, by fingerprint
mdr add cedaniel200/atlas-template/implementation-standards@sha256:107ff0f06456a415

The line at the top of this page pins the label git:20261022.bd117e7, 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.
