| 3 | ## When to Use This Skill |
| 4 | |
| 5 | > **CRITICAL — Do not bypass this skill.** Whenever this skill is active, follow the patterns and constraints here. Do not substitute your own general knowledge of DevExpress APIs. If a scenario is not covered in the main skill body, read the relevant reference file or use MCP servers before writing code — do not guess API signatures. |
| 6 | |
| 7 | Use for any task involving: |
| 8 | - Creating `XtraReport` instances and building report structure in code |
| 9 | - Adding bands (DetailBand, GroupHeaderBand, ReportHeaderBand, etc.) |
| 10 | - Adding controls (XRLabel, XRTable, XRChart, XRPictureBox, etc.) to bands |
| 11 | - Binding reports to data sources (IList, DataTable, SqlDataSource, ObjectDataSource) |
| 12 | - Defining report parameters, calculated fields, and expression bindings |
| 13 | - Exporting reports: `ExportToPdf`, `ExportToXlsx`, `ExportToDocx`, `ExportToCsv`, etc. |
| 14 | - Configuring `PdfExportOptions`, `XlsxExportOptions`, etc. |
| 15 | - Saving/loading report layouts with `SaveLayoutToXml` / `LoadLayoutFromXml` |
| 16 | - Report types: table, master-detail, cross-tab, label, subreport |
| 17 | |
| 18 | > **Scope**: This skill covers runtime API only — no viewer UI, no print preview, no designer embedding. For platform-specific viewer integration, see: `devexpress-reports-aspnetcore`, `devexpress-reports-blazor`, `devexpress-reports-winforms`, or `devexpress-reports-wpf`. |
| 19 | |
| 20 | ## Before You Start |
| 21 | |
| 22 | If the host agent has a structured question-asking tool available, use it to ask these questions one at a time with clear options — for example, Claude Code's `AskUserQuestion` tool or GitHub Copilot's `askQuestions` tool. If no such tool is available, ask the questions directly in the chat response before generating code. |
| 23 | |
| 24 | Ask the developer: |
| 25 | |
| 26 | 1. **Target framework**: .NET 8+ or .NET Framework 4.x? |
| 27 | 2. **Platform**: WinForms, WPF, ASP.NET Core, Blazor, console/service, or MAUI? |
| 28 | 3. **Operation**: Create a new report in code? Load existing `.repx` layout? Modify an existing report class? |
| 29 | 4. **Data source**: What data are you binding? (IList/collection, DataTable/DataSet, EF DbContext, SQL database, JSON, Excel, none) |
| 30 | 5. **Output**: Export to file/stream? Which format(s)? Or display in a viewer? |
| 31 | 6. **Existing NuGet setup**: Are DevExpress packages already installed, or starting fresh? |
| 32 | |
| 33 | ## Prerequisites & Installation |
| 34 | |
