Description

Added a new Delphi Expert agent focused on Delphi/Object Pascal development.

This agent helps with Delphi project tasks such as VCL/FMX development, Object Pascal best practices, database access, FireDAC/Oracle usage, REST integrations, component development, memory/resource management, threading, and automated testing with DUnitX.

The agent includes Delphi-specific guidance for:

Generating production-ready Delphi/Object Pascal code
Respecting Delphi version compatibility, especially Delphi 10.x
Creating DUnitX tests using a known-good runner structure
Supporting TestInsight and CI-friendly test execution
Registering newly created units in .dpr or .dpk files so they appear correctly in the Delphi IDE Project Manager
Avoiding loose .pas files that are not tracked by the project

The purpose is to provide a specialized AI assistant for developers maintaining or modernizing Delphi applications, especially enterprise desktop systems that rely on VCL, databases, and legacy-compatible tooling.

Type of Contribution

• New instruction file.
• New prompt file.
• New agent file.
• New plugin.
• New skill file.
• New agentic workflow.
• Update to existing instruction, prompt, agent, plugin, skill, or workflow.
• Other (please specify):

Additional Notes

This contribution adds a Delphi/Object Pascal specialist agent based on the existing expert-agent structure used by other language agents.

The agent is intentionally focused on practical Delphi development, including legacy and enterprise scenarios where Delphi is still widely used. It includes guidance for VCL/FMX applications, database-heavy systems, FireDAC/Oracle usage, REST integrations, component development, memory/resource ownership, threading, and automated testing.

A few Delphi-specific points were added because they are important in real Delphi projects:

DUnitX tests should include a functional .dpr runner, not only test fixture units.
The DUnitX runner template includes TestInsight support, console logging, NUnit XML output, RTTI discovery, and CI-safe behavior.
New .pas units created during refactoring should be registered in the .dpr or .dpk so they appear in the Delphi IDE Project Manager.
The agent avoids assuming the latest Delphi version and gives special attention to Delphi 10.x compatibility.

The goal is to help Delphi developers get useful, compilable, maintainable code and avoid common Delphi-specific issues that generic coding agents often miss.
