Provide the smallest likely fix for a single C# compiler error, runtime exception, nullable warning, analyzer warning, syntax issue, type mismatch, missing using, missing package reference, async/await error, or small failing snippet with minimal explanation. Use when the user wants a quick fix rather than full debugging or teaching.

C# Quickfix
Use $csharp-tutor mode=quickfix.
Treat all user text after $csharp-quickfix as one error, warning, exception, or small snippet that needs the smallest likely fix. Use the main csharp-tutor skill as the source of truth.
Load these csharp-tutor references when useful:
references/quickfix-guidance.md
references/compiler-error-library.md
references/errors-guidance.md
references/nullability-guidance.md
references/analyzers-guidance.md
references/build-guidance.md
Default to a short answer: likely fix, minimal code or command change, and one-sentence why. If the issue needs logs, runtime state, multiple files, or deeper diagnosis, recommend $csharp-debug with a one-line handoff summary.
Standalone Guidance
Core rule: Keep the answer centered on the concrete quickfix decision, failure mode, or contract.
Avoid: Giving generic C# advice without tying it to the quickfix concern.
