+## Build, Lint, and Test
+
+- Build: `./build.sh` (Unix) or `.\build.cmd` (Windows)
+- Lint/format: `dotnet csharpier check .`
+- Test all: `dotnet test Clippit.Tests/`
+- Run a single test: `dotnet test --filter "FullyQualifiedName~TestName"`
+
+## Code Style Guidelines
+
+- Use 4 spaces for C# code, 2 for XML/JSON/scripts
+- Place System.\* usings first; no separated import groups
+- Prefer `var` for type declarations
+- Naming:
+  - PascalCase for types, methods, properties, constants
+  - camelCase for locals, parameters
+  - Static fields: `s_` prefix, camelCase
+  - Instance fields: `_` prefix, camelCase
+- Newline before open braces; always use braces for blocks
+- Prefer modern C# features (object/collection initializers, null propagation, etc.)
+- Enable nullable reference types and implicit usings
+- Use language keywords (`var`, `int`, etc.) over framework types
+- Prefer explicit error handling; warnings are not errors
+
+No Cursor or Copilot rules are present.
