Provides file paths to language-specific extension files for the code-testing pipeline. Read this reference-only catalog for extension guidance files (e.g., dotnet.md for .NET, cpp.md for C++). Agents and skills read its bundled files directly; do not invoke this catalog through the model's skill tool.
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
# Code Testing Extensions This reference-only catalog lists bundled guidance for the code-testing pipeline. Read the matching file directly; do not invoke this catalog as a skill. Resource paths are relative to this catalog, not the project workspace. ## Available Extension Files | File | Language | Contents | |------|----------|----------| | [extensions/dotnet.md](extensions/dotnet.md) | .NET (C#/F#/VB) | Build commands, test commands, project reference validation, common CS error codes, MSTest template | | [extensions/python.md](extensions/python.md) | Python | Framework-adaptive test commands (pytest, custom runners), project layout detection, mocking guidelines, common errors | | [extensions/typescript.md](extensions/typescript.md) | TypeScript/JavaScript | Build/test commands (Jest/Vitest/Mocha), framework detection, mocking, TS-specific considerations | | [extensions/powershell.md](extensions/powershell.md) | PowerShell | Test commands (Pester v5), module import patterns, discovery/run pitfalls, mocking, common errors | | [extensions/cpp.md](extensions/cpp.md) | C++ | Testing internals with friend declarations | …

How to install
mdr add dotnet/skills/code-testing-extensions@sha256:81149d3622f5e358The line at the top of this page pins the label git:20261009.e191d40, 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.
