List all available LLM providers and their models.
AI agents call list_llm_providers to retrieve information from Session Buddy without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about available LLM providers and their supported models. It performs no write, destructive, or execute operations—purely retrieving and presenting existing data. The blast radius of misuse is minimal since it only exposes metadata about available providers without enabling actual operations on them.
From the tool's definition Tool name 'list_llm_providers' and description 'List all available LLM providers and their models' indicate a read-only operation that retrieves configuration information without modification or side effects.
