Apply the Cratis C# house conventions when writing or reviewing C# in a Cratis repository - formatting, naming, records and primary constructors, nullable handling, XML documentation, custom exceptions, structured logging, dependency injection, and service lifetimes. Use for any "how should this be written" C# style question; defer product API decisions and specification authoring to their focused workflows.
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
# Cratis C# engineering conventions These are the house conventions Cratis maintainers apply across every repository. They are **conventions**, not framework contracts: nothing here is enforced by an analyzer unless this skill says so. Follow them for consistency; do not claim the framework requires them. ## Verified product sources | Package | Purpose | | --- | --- | | `Cratis.Fundamentals` | DI lifetime attributes and `IInstancesOf<T>` instance resolution | ## Route near misses - The question is what a Cratis product API *does*: resolve it against the owning product repository, not against this style guide. - The subject is a specification file: the specification conventions own the `Establish`/`Because`/`should_` pattern and the `for_`/`when_` hierarchy. - The subject is TypeScript or React: this skill covers C# only. - The subject is repository structure or documentation: those are separate workflows. ## Quick reference - Use current C# language features — records, primary constructors, pattern matching, collection expressions. - `var` over an explicit type; the right-hand side already names the type. - File-scoped namespace declarations. …

How to install
mdr add cratis/ai/cratis-engineering-csharp-conventions@sha256:54c632c9c76f7b00The line at the top of this page pins the label git:20261013.d89a1b7, 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.
