Overview

Concrete tool for performing semantic search within code documentation sites using RAG provided by CrewAI.

Description

The CodeDocsSearchTool class extends RagTool to enable semantic searches within code documentation sites using natural language queries. It provides two operational modes: a fixed documentation URL mode where docs_url is set during initialization (using FixedCodeDocsSearchToolSchema), and a dynamic mode where docs_url is passed at runtime (using CodeDocsSearchToolSchema). The add method registers documentation URLs with the RAG system using DataType.DOCS_SITE, and the _run method performs semantic searches with optional similarity_threshold and result limit parameters. The tool description is dynamically generated based on whether a fixed docs_url is provided.

Usage

Use this tool when CrewAI agents need to reference API docs, programming guides, or technical specifications during development or troubleshooting tasks.
