csharp-dotnet
100 / 100 · Low risk
Fine to try.
Use when building on .NET 8+ with C# 12. Covers nullable reference types, records, async/await correctness, minimal APIs, dependency injection, and EF Core query performance. Trigger on "async deadlock in my asp.net app", "turn on nullable reference types", "ef core is doing n+1 queries", "set up a minimal api in .net 8". Do not use for tuning the database itself — see the database-performance skill.
What this skill can do
We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.
Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'csharp-dotnet' ] || [ -L ~/.agents/skills/'csharp-dotnet' ]; then echo 'A skill folder named csharp-dotnet already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/nimadorostkar/Claude-Skills-collection' "$d" && git -C "$d" checkout --quiet '1691932edc17063d712a85d02bcc7a1cd3791057' -- 'skills/languages/csharp-dotnet' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/languages/csharp-dotnet' ~/.agents/skills/'csharp-dotnet' && rm -rf "$d"; fi
Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'csharp-dotnet' ~/.claude/skills/'csharp-dotnet' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
