Apply Martin Fowler-inspired enterprise architecture rules when choosing layers, service layers, transaction scripts, domain models, repositories, mappers, or DTOs.
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
# Patterns of Enterprise Application Architecture Skill Use this skill when a task involves enterprise application structure, layering, service layer, transaction script, domain model, data mapper, repository, unit of work, identity map, DTOs, or integration patterns. Before making design or code decisions, read and apply [patterns-of-enterprise-application-architecture.mini.md](patterns-of-enterprise-application-architecture.mini.md). Use [patterns-of-enterprise-application-architecture.md](patterns-of-enterprise-application-architecture.md) only as a deeper reference when the mini rules are not enough for the current enterprise-pattern tradeoff.

How to install
mdr add ciembor/agent-rules-books/patterns-of-enterprise-application-architecture@sha256:fa705698efa8ef9dThe line at the top of this page pins the label git:20260909.802595f, 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.
