SAGE Tool Use

Tool retrieval and ranking algorithms for LLM agents

🎯 Overview

sage-agentic-tooluse provides a comprehensive suite of tool selection and ranking algorithms for LLM agents:

• Keyword Selector: Fast matching based on keyword overlap
• Embedding Selector: Semantic similarity using embeddings
• Hybrid Selector: Combines keyword and embedding approaches
• DFS-DT Selector: Decision tree-based tool selection
• Gorilla Selector: Gorilla-style tool retrieval

📦 Installation

# Basic installation
pip install isage-agentic-tooluse

# Development installation
pip install isage-agentic-tooluse[dev]

🚀 Quick Start

Keyword-based Tool Selection

from sage_libs.sage_agentic_tooluse import KeywordSelector, ToolSelectionQuery

# Create selector
selector = KeywordSelector.from_config(config=keyword_config, resources=resources)

# Select tools for a query
selected = selector.select(
    query=ToolSelectionQuery(
        sample_id="q1",
        instruction="Get current weather in New York",
        candidate_tools=["weather_api", "search_api"],
    ),
    top_k=5
)

for tool in selected:
    print(f"Tool: {tool.tool_id}, Score: {tool.score}")

Embedding-based Tool Selection

from sage_libs.sage_agentic_tooluse import EmbeddingSelector, ToolSelectionQuery

# Create selector with embedding model
selector = EmbeddingSelector.from_config(config=embedding_config, resources=resources)

# Select tools based on semantic similarity
selected = selector.select(
    query=ToolSelectionQuery(
        sample_id="q2",
        instruction="What's the weather like?",
        candidate_tools=["weather_api", "search_api"],
    ),
    top_k=5
)

Hybrid Tool Selection

from sage_libs.sage_agentic_tooluse import HybridSelector, ToolSelectionQuery

# Combine keyword and embedding approaches
selector = HybridSelector.from_config(config=hybrid_config, resources=resources)

selected = selector.select(
    query=ToolSelectionQuery(
        sample_id="q3",
        instruction="Find tools for weather updates",
        candidate_tools=["weather_api", "search_api", "calendar_api"],
    ),
    top_k=5,
)
