Use when reviewing .NET hot paths or scanning source for allocation-heavy and inefficient patterns. Not for measuring a running process, benchmark design or SIMD optimization.
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
<!-- Modified by Cratis from dotnet's original (MIT): frontmatter, applicability, navigation and the changes listed in NOTICE. Upstream: https://github.com/dotnet/skills (plugins/dotnet-diag/skills/analyzing-dotnet-performance/SKILL.md; see NOTICE) --> # .NET Performance Patterns Cratis rules in `.cratis/ai/rules/` (including `csharp.md`, `specs.csharp.md`, and `orleans.md`) and the `cratis-*` skills win where they differ. Scan C#/.NET code for performance anti-patterns and produce prioritized findings with concrete fixes. Patterns sourced from the official .NET performance blog series, distilled to customer-actionable guidance. ## When to Use - Reviewing C#/.NET code for performance optimization opportunities - Auditing hot paths for allocation-heavy or inefficient patterns - Systematic scan of a codebase for known anti-patterns before release - Second-opinion analysis after manual performance review ## When Not to Use - **Algorithmic complexity analysis** — this skill targets API usage patterns, not algorithm design - **Code not on a hot path** with no performance requirements — avoid premature optimization ## Inputs | Input | Required | Description | …

How to install
mdr add cratis/ai/analyzing-dotnet-performance@sha256:80b4bc80a7f1aaefThe line at the top of this page pins the label git:20261026.fc845e3, 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.
