Coding standards, frameworks, refactoring, and code review (15.8K skills)
Commit local changes to the current Git branch with a message based on the project's conventions. When staged and unstaged changes coexist, choose which to include. The skill does not push changes or create pull requests.
Review local branches, pull requests, commits, or files and address issues. The skill selects a single-agent or multi-agent workflow based on the environment, with automatic fixes for lower-risk issues and confirmation for high-risk changes.
Search GitHub, Stack Overflow, Hacker News, and HuggingFace for code examples, projects, technical answers, discussions, models, datasets, and Spaces. Filter supported searches and receive structured JSON results containing titles, links, and snippets.
Diagnose why the dotnet-msbuild binlog MCP server will not start or connect. Check the selected SDK, package sources, and launch logs, then identify a recovery that respects organizational policies and verify that the host discovers the server’s tools.
Use the new Process APIs in .NET 11 applications to run external commands, capture output and errors, and manage child processes. Guidance covers waiting for completion, reading output, and controlling whether processes survive their parent.
Match C# and .NET tasks to the appropriate specialist skill using the request and project evidence. Invoke available specialists, explain how to obtain missing plugins, and complete suitable tasks with standard tooling when possible.
Create the starting files for a new agent skill, including SKILL.md, metadata, and optional folders. It guides descriptions that help agents select the skill, actionable workflows, ownership entries, and validation checks.
Create VS Code custom agents for roles such as planning or code review. It builds .agent.md files with role instructions, permitted tools, and optional handoffs that let users move work to another agent.
Write and repair custom MSBuild targets, the steps that organize build tasks. Preserve existing build sequences, choose appropriate insertion points, distinguish returned results from rebuild checks, and register generated files for cleanup.
Create .NET projects from templates and align them with neighboring projects and centralized package versions. Validate options, connect projects in a solution, and build the result to check that the generated structure works.
Apply the System.Text.Json APIs introduced in .NET 11 to produce PascalCase JSON names and retrieve typed serialization metadata, the information used to convert objects. Create runnable examples and check metadata availability without exception-based probing.
Migrate legacy .NET project files to SDK-style format, reducing repetitive XML and explicit file lists. Convert package references, move assembly metadata into project settings, and consolidate shared build and package settings across multiple projects.
Review custom dotnet new templates before publishing. Check required fields, parameter types and defaults, command name conflicts, and constraints, then receive findings grouped by severity with concrete fixes for errors and warnings.
Upgrade MSTest v1 or v2 projects to v3, including partially completed migrations. Update packages, repair affected assertions and test data, replace legacy settings, and compare test results while preserving the existing test runner.
Create, modify, debug, and review Windows Forms applications while preserving their editable layouts in Visual Studio Designer. Covers resizing, data binding, asynchronous UI behavior, and checks that distinguish successful builds from actual screen and designer verification.
Upgrade an existing .NET 8 project to .NET 9 by addressing build errors and compatibility changes. Update related packages, containers, and build pipelines, then verify the migration with clean builds and tests.
Install a .NET SDK, the tools used to build .NET projects, inside a project folder. Configure version selection and shared setup scripts to test previews or reproduce team and CI environments without changing the system installation.
Investigate MSBuild failures, measure slow builds, or review existing build definitions. Use binary logs, project settings, and comparable timing measurements to identify causes, propose focused repairs, and verify behavior without broad configuration changes.
Refactor C#/.NET code through renaming, extraction, consolidation, and other structural changes while preserving behavior. Check compatibility beyond code references, including public APIs and serialized names, then validate with builds and relevant tests.
Migrate .NET Framework code that forcibly stops threads to cooperative cancellation, where work checks and responds to stop requests. The skill covers loops, timeouts, blocked threads, and ASP.NET request endings, with cleanup and validation guidance.
Introduce nullable reference types into an existing C# project, making explicit which references may be null. Plan a staged migration, resolve compiler warnings, and clarify public API annotations while preserving runtime behavior.
Move existing .NET 9 projects to .NET 10 by updating project settings and dependencies, fixing build errors, and reviewing behavior changes. Includes CI and Docker updates, followed by builds, tests, and security checks.
Upgrade an existing .NET 10 project to .NET 11 by updating framework targets and packages, fixing compatibility issues, reviewing runtime behavior changes, and verifying builds, tests, and deployment configuration.
Prepare .NET projects for Native AOT, compilation before execution, and trimming, which removes unused code. Use build warnings to guide type annotations, reflection changes, and source-generated JSON serialization, then check all target frameworks.
