What is devexpress-vcl-reports?

A reporting guide for DevExpress VCL applications written in Delphi or C++Builder. It covers report layouts, data connections, a viewer, and a designer for creating or viewing reports.

Use it to build report viewers and designers, connect report data, define report parameters, and work with REPX report layout files.

It explains the VCL-specific pieces needed to connect DevExpress Reports to these applications instead of treating them like ordinary web reports.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00230	$0.05010
Opus 5.5	$0.00092	$0.02004
Sonnet 5.5	$0.00046	$0.01002
Haiku 4.5	$0.00023	$0.00501

Security

Grade A, and why

devexpress-vcl-reports scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/check-form-load.ps1, scripts/harness/build-harness.cmd, scripts/inspect-viewer.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

DevExpress VCL Reports (ExpressReports)

VCL Reports is the DevExpress Reports engine for Delphi and C++Builder. The reporting backend (VCLBackend.exe) is embedded in the executable and started on demand. The Report Viewer and Report Designer are the DevExpress web Document Viewer and Report Designer hosted in WebView2. A report layout is a standard XtraReports REPX XML document, so anything inside a layout (bands, controls, expressions, data sources, parameters, styles) follows DevExpress Reports (XtraReports) documentation; only the Delphi/C++Builder side is VCL-specific.

Applies to DevExpress VCL v26.1+.

Required Units

Unit	Purpose
`dxReport`	`TdxReport` (non-visual: `ShowViewer`, `ShowDesigner`, `ExportTo*`, `Layout`, `Parameters`)
`dxReport.Control`	`TdxReportControl` (embedded viewer)
`dxReport.Parameters`	`TdxReportParameter` (add it when you declare variables of this type; `Parameters['P'].Value` alone compiles without it)
`dxBackend`	`TdxBackendDataConnectionManager`, `TdxBackend`, `TdxReportExportFormat`
`dxBackend.Bundled`	Backend lifetime helpers. Keep it in `uses` of console/service apps
`dxBackend.ConnectionString.SQL`	`TdxBackendDatabaseSQLConnection` (XPO connection string: SQL Server, SQLite, PostgreSQL, ...)
`dxBackend.ConnectionString.JSON`	`TdxBackendInMemoryJSONConnection` (URI or inline JSON)
`dxBackend.ConnectionString.JSON.DataSet`	`TdxBackendDataSetJSONConnection`, `TdxBackendDataSetCollectionItem` (any `TDataSet`)
FireDAC driver units	Only when the data comes from a FireDAC dataset (the built-in SQL connection needs none): the full list, including `FireDAC.Phys.SQLiteWrapper.Stat` for SQLite, is in design-time-dfm.md. A connection set up only in the `.dfm` does not link them

uses dxReport, dxBackend, dxBackend.ConnectionString.JSON.DataSet;   // + others from the table as used

#include "dxReport.hpp"
#include "dxBackend.hpp"
#include "dxBackend.ConnectionString.JSON.DataSet.hpp"
#pragma link "dxReport"
#pragma link "dxBackend"
// A dotted unit name needs the object-file extension, or the linker reads the last segment as one
// ("Unable to open file 'DXBACKEND.CONNECTIONSTRING.SQL'"):
#if defined(_WIN64)
#pragma link "dxBackend.ConnectionString.JSON.DataSet.o"
#else
#pragma link "dxBackend.ConnectionString.JSON.DataSet.obj"
#endif

In C++, read a report parameter by name with FReport->Parameters->ParamByName["P"]->Value.

What ships with it

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

devexpress-vcl-reports is a skill published in the GitHub repository DevExpress/agent-skills (70 stars, last pushed yesterday), licensed MIT. It adds 230 tokens to every session and 5,010 once invoked, about $0.0009 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-11-10.
