# DevToys vs semantic-kernel

- Only in DevToys: CommunityToolkit.Mvvm, Microsoft.AspNetCore.Components.WebView, Microsoft.AspNetCore.Components.Web, Blazor, SixLabors.ImageSharp, Microsoft.Extensions.Logging.Debug, split-grid
- Only in semantic-kernel: Npgsql, OpenAI, Microsoft.Extensions.Hosting, AIOHTTP, EntityFramework, System.IdentityModel.Tokens.Jwt, azure-identity, Azure.AI.OpenAI, Microsoft.Extensions.AI.AzureAIInference, Microsoft.Extensions.AI.OpenAI, azure-ai-agents, Microsoft.Extensions.AI, azure-ai-projects, MCP, Microsoft.ML.OnnxRuntime, Handlebars.Net, YamlDotNet, defusedxml, DocumentFormat.OpenXml, jinja2, JsonSchema.Net, JsonSchema.Net.Generation, Pydantic, Microsoft.OpenApi, openapi-core, Microsoft.Extensions.Logging.Console, opentelemetry-api, OpenTelemetry

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
