"""Headroom integrations with popular LLM frameworks.

Available integrations:

LangChain (pip install headroom[langchain]):
    - HeadroomChatModel: Drop-in wrapper for any LangChain chat model
    - HeadroomChatMessageHistory: Automatic conversation compression
    - HeadroomDocumentCompressor: Relevance-based document filtering
    - HeadroomToolWrapper: Tool output compression for agents
    - StreamingMetricsTracker: Token counting during streaming
    - HeadroomLangSmithCallbackHandler: LangSmith trace enrichment

Agno (pip install agno):
    - HeadroomAgnoModel: Drop-in wrapper for any Agno model
    - HeadroomPreHook/HeadroomPostHook: Agent-level hooks for tracking
    - create_headroom_hooks: Convenience function to create hook pairs

MCP (Model Context Protocol):
    - HeadroomMCPCompressor: Compress MCP tool results
    - compress_tool_result: Simple function for tool compression

Example:
    # LangChain integration
    from headroom.integrations import HeadroomChatModel
    # or explicitly:
    from headroom.integrations.langchain import HeadroomChatModel

    # Agno integration
    from headroom.integrations.agno import HeadroomAgnoModel
    # or explicitly:
    from headroom.integrations.agno import HeadroomAgnoModel

    # MCP integration
    from headroom.integrations import compress_tool_result
    # or explicitly:
    from headroom.integrations.mcp import compress_tool_result
