SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Route user queries and agent requests quickly and deterministically using semantic vector matching to avoid slow LLM-only routing, reduce latency, and improve precision for intent classification and tool invocation.

Core Features & Use Cases

  • High-speed intent classification: Match queries to predefined routes using embedding similarity instead of expensive generation.
  • Dynamic function calling: Extract parameters and generate function-call schemas for executing tasks programmatically.
  • Flexible index and encoder support: Work with local encoders or API encoders and backends like Local, Pinecone, Qdrant, or Postgres for production.
  • Use Case: Build a chatbot routing layer that identifies user intent, blocks sensitive topics, and triggers appropriate backend functions with extracted parameters.

Quick Start

Use the semantic-router to classify an input query and return the best-matching route name plus any function call arguments.

Frequently Asked Questions about semantic-router

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How does semantic routing improve intent classification for LLMs?

Semantic routing improves intent classification by matching user queries to predefined routes using embedding similarity, bypassing slow LLM generation to reduce latency and increase decision speed.

Can I use Pinecone or Qdrant for vector search in semantic routing?

Yes, you can use Pinecone or Qdrant for vector search. Semantic routing supports flexible indexes including Local, Pinecone, Qdrant, and Postgres for production deployments.

How do I route user queries to dynamic function calls using embeddings?

You route user queries to dynamic function calls by applying semantic vector matching to extract parameters and generate function-call schemas for executing tasks programmatically.

What encoders work with semantic routing for fast tool routing?

Fast tool routing works with multiple encoders including OpenAI, Cohere, HuggingFace, and FastEmbed, allowing you to choose between local or API-based embedding generation.

When should I use semantic vector matching instead of LLM-only routing?

Use semantic vector matching instead of LLM-only routing when you need high-speed, deterministic decision-making to avoid generation latency and improve precision for tool invocation.
