AI Agent

Fast 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'

Import

python
from praisonaiagents.context import fast
