What dotnet-inspect-decompiler does

This skill inspects a selected .NET type or member and renders reconstructed C#, annotated C# with IL details, or raw IL. It can resolve an overload, show a signature, and search public API methods for a chosen C# body shape such as object creation or a try statement.

Searches stay scoped to an assembly, type, or member. Results can include a qualified member selector, MethodDef token, rendered-body range, and the matching text. Run restore and build first when project dependencies changed. Package and PDB acquisition may use the network, so --offline is required when the analysis must stay local.

What it helps with

reconstruct C# from a .NET assembly
compare decompiled code with raw IL
find methods by C# body shape
inspect offsets, branches, and calls
select a specific overloaded member

Example prompts for the agent

Inspect type JsonSerializer from package System.Text.Json and show reconstructed C# plus IL with --offline.
Search MyLib.dll for methods where Kind=TryStatement, returning JSONL results.
Render member JsonSerializer selector Serialize:1 as Decompiled Source and Annotated Source.

Questions about dotnet-inspect-decompiler

How do I install dotnet-inspect-decompiler in Claude Code?

Run npx skills add richlander/dotnet-inspect --skill decompiler -a claude-code, then check ~/.claude/skills/decompiler/SKILL.md.

What does dotnet-inspect-decompiler do?

It reconstructs C# and displays IL for a selected type or member. It can also search assembly-scoped method bodies for a specified C# shape.

What does --offline change?

The flag blocks network acquisition of packages and PDB files. The resulting evidence set uses locally available assembly data.
