Use when writing or refactoring Ruby/Rails code, structuring app/modules/[feature]/ layers, or defining contracts/ modules (SOLID, files within FUSE_SOLID_MAX_LINES).
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
<objective> SOLID Ruby enforces a modular architecture for Ruby 4.0+/Rails 8: every feature lives under `app/modules/[feature]/` (controllers, services, repositories, contracts, models) with shared code in `app/modules/core/`, contracts (duck-typing modules) live only in `contracts/` directories, `# frozen_string_literal: true` is required in every file, and every public method carries YARD documentation. Before writing any new code it requires a DRY check against `app/modules/core/services` and `app/modules/core/contracts`. See `solid-principles.md` for the overview, the per-principle references for SRP/OCP/LSP/ISP/DIP detail, and the templates for module/service/contract/model/error/test scaffolding. </objective> # SOLID Ruby - Modular Architecture ## Agent Workflow (MANDATORY) Before ANY implementation, spawn 3 agents in parallel, one `Agent` call each with a `name`: 1. **fuse-ai-pilot:explore-codebase** - Analyze existing architecture 2. **fuse-ai-pilot:research-expert** - Verify Ruby/Rails docs via Context7 3. **fuse-ai-pilot:sniper** - Post-implementation validation --- ## DRY - Reuse Before Creating (MANDATORY) **Before writing ANY new code:** …

How to install
mdr add fusengine/agents/solid-ruby@sha256:a58de4ed78bc1657The line at the top of this page pins the label git:20261012.499a4d1, 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.
