Core SDKFast Context module for rapid parallel code search.This module implements a specialized subagent that retrieves relevant code
from a codebase using parallel tool calls, similar to Windsurf’s Fast Context.Key features:
Parallel tool execution (up to 8 concurrent calls)
Limited serial turns (max 4) for fast response
Restricted tool set (grep, glob, read) for safety
Returns files + line ranges (no summarization)
Optional optimizations (no performance impact when disabled):
Ripgrep backend: Use search_backend='ripgrep' for faster grep
Async file I/O: Uses aiofiles if installed
Incremental indexing: Use enable_indexing=True
Context compression: Use compression='truncate' or compression='smart'
