CrestApps.Core AI Templates

Prompts are Markdown files with YAML front matter, rendered with Liquid (Fluid) and discovered from embedded resources, the file system, code, or custom providers.

Guidelines

• AddCoreAIServices() already chains AddCoreAITemplating(); call it directly only when using templating on its own.
• Keep each template to one concern (tone, safety, RAG rules) and compose at runtime with MergeAsync or profile selections.
• Put system prompts under Templates/Prompts/ (their Kind defaults to SystemPrompt). Files directly under Templates/ must declare Kind. Generic Templates/ discovery is not recursive.
• Use a persona (crestapps-core-ai-personas) for identity and voice instead of copying the same persona prompt into many templates.
• All ITemplateService and ITemplateProvider methods take an optional CancellationToken; pass it through.

Registration

using CrestApps.Core.Templates.Extensions;

builder.Services.AddCoreAITemplating(options =>
{
    options.AddDiscoveryPath("/app/templates");
});

// Embedded .md resources under Templates/ in an assembly.
builder.Services.AddTemplatesFromAssembly(typeof(Program).Assembly, source: "MyApp");

AddCoreAITemplating() builds on AddTemplating() and adds the Profile and SystemPrompt template sources, the AI profile template manager, and AIProfileSystemPromptTemplateProvider.
