backend-architecture SKILL.md skillA
backend-architecture from johnkozaris/jko-claude-plugins is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

This skill should be used for consequential backend architecture decisions: module or service boundaries; modular monoliths versus independent services; service extraction and data migration; data ownership and consistency; synchronous, event-driven, actor/stateful, or pipeline designs; failure isolation, backpressure, deployment topology; or deciding where orchestration and invariants belong. Trigger on requests to review or design a backend, split a service, choose a queue or communication…
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
# Backend Architecture Start from the system that exists, not from an architecture diagram you already want to impose. ## Investigate before choosing Inspect entry points, module boundaries, data stores, call paths, deployment units, tests, and recent changes. Where available, inspect runtime signals, incident and deployment history, data growth, and ownership or regulatory constraints. Identify the constraint driving the decision: independent deployment, failure isolation, data ownership, latency, throughput, team ownership, regulatory separation, or simply code that is hard to change. Separate evidence from assumptions and perform a blind-spot pass before converging. Research what the repository, telemetry, and primary documentation can answer; prioritize remaining user questions by how likely their answers are to change the architecture. Do not use remembered version trivia as evidence. ## Production opinions - **Default to a modular monolith.** A process boundary must earn its network, operational, consistency, and observability costs. Split a service when the system needs independent deployment, failure isolation, scaling, ownership, …

How to install
mdr add johnkozaris/jko-claude-plugins/backend-architecture@sha256:c35f2474bda244b2The line at the top of this page pins the label git:20260725.6c1b23d, 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.
