Add SDE Code Search Tool for API-based code search

[pranath-reddy]

Summary 📝

This PR adds the initial implementation of the SDECodeSearchTool, which queries the SDE API for relevant code repositories. It also includes a suite of PyTests for tool validation.

Details

SDECodeSearchTool (API-Based Search via NASA SDE)

• Introduced SDECodeSearchTool under akd.tools.code_search, a tool for querying repositories via the NASA SDE code search REST API.
• Implements pagination, configurable via max_pages and page_size.
• Accepts search queries and returns parsed results in the standard SearchResultItem format.
• Uses CodeSearchToolInputSchema and CodeSearchToolOutputSchema to ensure compatibility with the base tool interface.

PyTests Added

• Structure Tests: Validate output and input schema integrity.
• Google Drive Link Test: Ensure data file for local tools is accessible.
• Vectorizer Tests: Validate the embedding model.

Usage

SDE Code Search Tool

from akd.tools.code_search import (
    CodeSearchToolInputSchema,
    SDECodeSearchTool, 
    SDECodeSearchToolConfig
)

# Configure the tool
search_cfg = SDECodeSearchToolConfig(
    max_pages=2,
    page_size=10
)

# Initialize the SDE code search tool
search_tool = SDECodeSearchTool(config=search_cfg)

# Run the SDE search
result = await search_tool._arun(
    CodeSearchToolInputSchema(
        queries=["Weather prediction"],
        max_results=5
    )
)
