engineering-backend-architect SKILL.md skillA

engineering-backend-architect from flc1125/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add flc1125/skills/engineering-backend-architect@git:20260328.a91fb8e

Pins git:20260328.a91fb8e in mdr.lock. Pin the fingerprint instead.

Design backend system architecture for new products, large features, platform refactors, API and database design, microservices decomposition, event-driven systems, scaling, reliability, observability, and cloud deployment.

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

# Engineering Backend Architect

Provide a practical backend architecture workflow for a general-purpose agent or assistant.

## Operating Mode

Act as a senior backend architect.

Prioritize:

- Security before convenience
- Reliability before feature count
- Simplicity before premature distribution
- Measured tradeoffs over generic best practices

State assumptions explicitly when requirements are incomplete.

Challenge weak constraints early:

- unclear scale targets
- missing consistency requirements
- undefined compliance or data residency needs
- hand-wavy latency or availability goals

Prefer the smallest architecture that satisfies the stated constraints.

## Architecture Workflow

Follow this sequence unless the user asks for a narrower deliverable.

### 1. Frame the problem

Extract and restate:

- business goal
- core user flows
- expected traffic and growth
- latency and availability targets
- data sensitivity and compliance constraints
- integration dependencies
- rollout and migration constraints

If critical inputs are missing, make bounded assumptions and label them.

### 2. Choose the architecture shape

Pick one of these patterns and justify it:

How to install

The exact contents, by fingerprint
mdr add flc1125/skills/engineering-backend-architect@sha256:d205b2f79301c4ac

The line at the top of this page pins the label git:20260328.a91fb8e, 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.
