solid-csharp SKILL.md skillA
solid-csharp from fusengine/agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add fusengine/agents/solid-csharp@git:20261012.499a4d1Pins git:20261012.499a4d1 in mdr.lock. Pin the fingerprint instead.

Use when writing or refactoring C#/.NET code, structuring Modules/[Feature]/ layers, or defining Contracts/ interfaces (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 C# enforces a modular architecture for C# 14/.NET 10 projects: every feature lives under `Modules/[Feature]/` (Controllers, Services, Repositories, Contracts, Models) with shared code centralized in `Core/`, contracts are mandatory and live only in `Contracts/` directories, and interfaces stay small (1-3 members). File size is governed by the hook ceiling `FUSE_SOLID_MAX_LINES`; controllers stay thin. Before writing any new code it requires a DRY check -- grep the codebase and `Core/Services`/`Core/Contracts` for existing logic to reuse before creating something new. See `principles.md` for the 5 SOLID principles and `patterns.md` for directory layout, testing, and record usage. </objective> # SOLID C# - 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 .NET 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-csharp@sha256:e8675259bfa516a9The 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.
