class Riffer::Providers::Base

Base class for all LLM providers in the Riffer framework.

Provides a template-method flow for text generation and streaming. Subclasses implement five hook methods; the base class orchestrates them.

Hook methods

build_request_params: convert messages, tools, and options into SDK params
execute_generate: call the SDK and return the raw response
execute_stream: call the streaming SDK, mapping events to the yielder
extract_token_usage: pull token counts from the SDK response
extract_content: extract text content from the SDK response
extract_tool_calls: extract tool calls from the SDK response

Constants

WIRE_SEPARATOR

Public Class Methods

skills_adapter ()

Source

# File lib/riffer/providers/base.rb, line 31
def self.skills_adapter
  Riffer::Skills::MarkdownAdapter
end

Returns the preferred skill adapter for this provider.

Override in subclasses for provider-specific formats.

  )
end

Generates text using the provider.
