Mythosia.AI.Abstractions

Core contracts and shared models for the Mythosia.AI ecosystem. Defines IAIService, all model types, and streaming primitives. Consumed by Mythosia.AI.Rag and any library that needs the AI service contract without pulling in heavy provider implementations.

Installation

dotnet add package Mythosia.AI.Abstractions

Install this package directly only when writing a library that depends on the AI service contract (e.g., RAG orchestration, custom middleware). Applications normally take a transitive dependency through Mythosia.AI.

Core Interface

`IAIService`

The central abstraction for AI completion and streaming.

public interface IAIService
{
    string Model { get; }
    string Provider { get; }
    string SystemMessage { get; set; }
    bool StatelessMode { get; set; }
    ChatBlock ActivateChat { get; }

    // Completion
    Task<string> GetCompletionAsync(string prompt);
    Task<string> GetCompletionAsync(Message message);
    Task<string> GetCompletionAsync(Message message, AIRequestContext context);
    // ... additional overloads with AIRequestProfile

    // Streaming
    IAsyncEnumerable<string> StreamAsync(string prompt, CancellationToken ct = default);
    IAsyncEnumerable<StreamingContent> StreamAsync(Message message, StreamOptions options, CancellationToken ct = default);
    // ... additional overloads
}

All concrete providers (ChatGptService, ClaudeService, GeminiService, etc.) in Mythosia.AI implement this interface.

Models

Type	Description
`Message`	A conversation message with role, content, and optional multimodal content
`MessageContent`	Base class for multimodal content (`TextContent`, `ImageContent`, `AudioContent`)
`ChatBlock`	Conversation container holding system message and message history
`ActorRole`	Message role enum (`System`, `User`, `Assistant`, `Function`)
`AIRequestContext`	Per-request context overrides (system message prefix/suffix, message override)
`AIRequestProfile`	Per-request parameter overrides (temperature, max tokens, stateless mode)
`AIModels`	Model identifier constants for all supported providers
`AIProvider`	Provider enum (`OpenAI`, `Anthropic`, `Google`, `xAI`, `DeepSeek`, `Perplexity`)

Streaming

Type	Description
`StreamingContent`	Streaming chunk with content, type, metadata, and token usage
`StreamingContentType`	Chunk type enum (`Text`, `Reasoning`, `FunctionCall`, `FunctionResult`, `Status`, `Error`, `Completion`)
`StreamOptions`	Streaming behavior options (metadata, function calls, reasoning)
`TokenUsage`	Token count data (input, output, cached, reasoning)

Functions

Type	Description
`FunctionDefinition`	Function schema for LLM function calling
`FunctionCallingPolicy`	Controls function calling behavior and iteration limits
`AiFunctionAttribute`	Marks a method as an AI-callable function
`AiParameterAttribute`	Describes a function parameter for the AI

Exceptions

Type	Description
`AIServiceException`	Base exception for AI service errors
`AgentMaxStepsExceededException`	Thrown when agent exceeds maximum iteration steps

Why This Package?

Mythosia.AI.Rag  →  Mythosia.AI.Abstractions  (zero heavy dependencies)
                     instead of
                     Mythosia.AI  (Azure.AI.OpenAI, NJsonSchema, TiktokenSharp, ...)

By depending on abstractions rather than the full implementation package, libraries like Mythosia.AI.Rag avoid pulling in provider-specific dependencies. The concrete provider is chosen by the final application.
