+# Organize Changes into Logical Commits
+
+Analyze all current git changes and organize them into logical, atomic commits. Follow these steps:
+
+1. **Analyze Changes**: Run git status and git diff to see all modified and untracked files
+2. **Review Content**: Examine the actual changes in each file to understand what was modified
+3. **Group Logically**: Group changes by:
+   - Feature or bug fix
+   - Service or component
+   - Related functionality
+   - UI changes vs business logic vs API changes
+4. **Create Commits**: For each logical group:
+   - Stage only the relevant files
+   - Create a descriptive commit message following conventional commit format
+   - Use prefixes like feat:, fix:, refactor:, chore:, docs:, etc.
+5. **Verify**: After all commits, show git log to confirm all changes were committed
+
+Important guidelines:
+- Keep commits atomic (one logical change per commit)
+- Write clear, descriptive commit messages
+- Don't mix unrelated changes in the same commit
+- Follow the existing commit message style in the repository
+- Include the Claude Code attribution at the end of each commit message

+# Repository Guidelines
+
+## Project Structure & Module Organization
+- Root solution: `ExportDXF.sln`.
+- WinForms app: `ExportDXF/ExportDXF/` (.NET Framework 4.8; SolidWorks automation). Key folders: `Forms/`, `Services/`, `Models/`, `Utilities/`, `Templates/`, `Resources/`, `ItemExtractors/`, `ViewFlipDeciders/`, `Extensions/`, `Properties/`.
+- Companion utilities: `EtchBendLines/` (standalone solution for DXF processing; includes vendored `netDxf`).
+- Sample docs: `TestDocs/` contains drawings/fixtures useful for local validation.
+- Tests: none yet; add new test projects under `tests/` (e.g., `tests/ExportDXF.Tests/`).
+
+## Build, Test, and Development Commands
+- Restore: `msbuild ExportDXF.sln /t:Restore` (or `nuget restore ExportDXF.sln`).
+- Build (Release): `msbuild ExportDXF.sln /p:Configuration=Release`.
+- Build single project: `msbuild ExportDXF/ExportDXF/ExportDXF.csproj /p:Configuration=Release`.
+- Run app: `ExportDXF/ExportDXF/bin/Release/ExportDXF.exe` (or `bin/Debug/ExportDXF.exe` after a Debug build).
+- Prereqs: Visual Studio 2019/2022 or Build Tools with .NET Framework 4.8 targeting pack; SolidWorks installed for automation features (app starts without SW but SW-dependent actions require it).
+- Format: `dotnet format` from repo root if .NET SDK is installed; otherwise use VS “Format Document”.
+
+## Coding Style & Naming Conventions
+- C#: 4-space indent, braces on new lines, nullable where supported.
+- Naming: PascalCase for types/methods; camelCase for locals/fields; `Async` suffix for async methods.
+- Structure: Keep UI in `Forms/` thin; delegate work to `Services/` and `Utilities/`. One class per file; filename matches type (e.g., `DxfExportService.cs`).
+- Interop: Isolate SolidWorks COM/interop behind interfaces for testability; prefer dependency injection where practical.
+
+## Testing Guidelines
+- Framework: xUnit recommended. Name files `*Tests.cs` and methods `MethodName_Should_DoThing`.
+- Location: `tests/ExportDXF.Tests/` with reference to the app or extracted class libraries.
+- Scope: Favor service- and utility-level tests; avoid UI surface. Mock/abstract SolidWorks interop.
+- Run: `dotnet test` (add when tests exist).
+
+## Commit & Pull Request Guidelines
+- Messages: imperative, present tense with optional scope (e.g., `ExportDXF: improve DXF export options`). Provide rationale in body and any breaking changes.
+- PRs include: clear description, linked issues (`Closes #123`), screenshots/GIFs for UI, migration notes, and local run steps.
+
+## Security & Configuration Tips
+- Do not commit secrets or license keys.
+- App configuration resides in `app.config`; user/machine-specific settings should stay in user config and not be committed.
+- Keep SolidWorks version/paths configurable where possible.
+
+## Agent Tools: Roslyn Bridge (C# Analysis)
+- Purpose: Use for C# code analysis, symbol queries, diagnostics, and semantic navigation via a local WebAPI bridge to Roslyn.
+- Golden rules:
+  - Always use this tool first for any C#/Roslyn analysis; do not guess.
+  - Always check service health/instances before querying.
+  - Default to `solutionName=ExportDXF` for this repo. If you intentionally open and analyze `EtchBendLines.sln`, use `solutionName=EtchBendLines`.
+- Service assumptions:
+  - WebAPI listens on `http://localhost:5001` when installed and running.
+  - Visual Studio must have the target solution open for the instance to appear.
+- Quick workflow (ExportDXF):
+  - List VS instances: `curl http://localhost:5001/api/instances`
+  - Health check: `curl http://localhost:5001/api/health`
+  - Diagnostics summary: `curl "http://localhost:5001/api/roslyn/diagnostics/summary?solutionName=ExportDXF"`
+  - Errors only: `curl "http://localhost:5001/api/roslyn/diagnostics?solutionName=ExportDXF&severity=error"`
+  - Warnings only: `curl "http://localhost:5001/api/roslyn/diagnostics?solutionName=ExportDXF&severity=warning"`
+  - All diagnostics: `curl "http://localhost:5001/api/roslyn/diagnostics?solutionName=ExportDXF"`
+  - List projects: `curl "http://localhost:5001/api/roslyn/projects?solutionName=ExportDXF"`
+  - Solution overview: `curl "http://localhost:5001/api/roslyn/solution/overview?solutionName=ExportDXF"`
+  - Find symbol by name: `curl "http://localhost:5001/api/roslyn/symbol/search?solutionName=ExportDXF&symbolName=TypeOrMember"`
+  - Symbol at file/position: `curl "http://localhost:5001/api/roslyn/symbol?solutionName=ExportDXF&filePath=C:/full/path/File.cs&line=10&column=5"`
+  - Find references: `curl "http://localhost:5001/api/roslyn/references?solutionName=ExportDXF&filePath=C:/full/path/File.cs&line=10&column=5"`
+- Notes:
+  - Lines are 1-based; columns are 0-based. Use absolute file paths.
+  - Get canonical file paths from the `projects` endpoint responses.
+  - Prefer this tool over manual grepping for symbols/references/diagnostics.
+- Troubleshooting:
+  - No instances listed: ensure Visual Studio is running with the solution open; wait up to 60s for discovery.
+  - Service not reachable: verify the Roslyn Bridge WebAPI service is installed and running on port 5001.
+
+- Helper script:
+  - `scripts/rb.ps1` provides short commands with defaults for this repo (defaults to `-SolutionName ExportDXF`).
+  - Examples: `./scripts/rb.ps1 summary`, `./scripts/rb.ps1 projects`, `./scripts/rb.ps1 symbol -SymbolName Program`.
