File contents

CSharpier — format C# (all files)

When to use

User wants all *.cs files formatted, or a directory / project run through CSharpier.
Before handoff or before commit when .cs is in scope (format-before-handoff-and-commit.mdc).

Preconditions

CSharpier is installed: global tool and/or local dotnet tool (manifest next to the repo).
Run from the repository root that contains the code (for Unity: often the folder above Assets, e.g. GridDungeonECS), unless the user names a different root.

Commands (pick what works in the environment)

Local tool — if dotnet-tools.json exists at repo root:
```
dotnet tool restore
dotnet csharpier format .
```
Global tool on PATH — common when the repo has no manifest (many Unity projects):
```
csharpier format .
```

Single file or subtree:

dotnet csharpier format path/to/File.cs
csharpier format path/to/File.cs
dotnet csharpier format Assets/SomeFolder
csharpier format Assets/SomeFolder

format . recursively formats .cs files per CSharpier configuration (e.g. .csharpierrc, csharpier.yaml, .editorconfig).

Agent workflow

Confirm root: Prefer the workspace’s git/Plastic root (parent of Assets for Unity projects) so formatting matches CI/editor.
Run via Shell from that root:
- If dotnet-tools.json is present: dotnet tool restore then dotnet csharpier format . (or scoped paths).
- Else try dotnet csharpier format . once; if it fails (“Could not execute”, tool not found), run csharpier format . (global).
If both fail: report that dotnet tool install csharpier --global or adding a local tool (dotnet new tool-manifest + dotnet tool install csharpier) is required; do not silently substitute another formatter.
Scope: “Format all .cs” → format . from chosen root. Do not limit to Assets only unless the user asked to scope there.

Notes

CSharpier does not format .uxml, .shader, etc. — C# only.
Windows PowerShell does not treat && as a command separator on older versions. Use ; or run Set-Location "d:\path\to\repo"; csharpier format . (or separate Shell invocations) instead of cd path && csharpier ….
