Pull request overview
This PR optimizes get_tool() in the Python porting workspace by replacing the per-call linear scan over PORTED_TOOLS with a lazily initialized, cached lookup map for O(1) access while preserving case-insensitive matching and first-match behavior.
Changes:
- Added
_get_tool_lookup()using@lru_cache(maxsize=1)andMappingProxyTypeto build an immutable, cached lowercased-name →PortingModulemapping. - Updated
get_tool()to perform constant-time lookup via the cached mapping. - Applied consistent formatting/quoting updates in
src/tools.py.

💡 What: Replaced the O(N) linear loop inside
get_toolwith an O(1) lazily initialized dictionary lookup (_get_tool_lookup). We useMappingProxyTypeand@lru_cacheto ensure the lookup dict is immutable, cached, and guarantees first-match priority as was done originally.🎯 Why: Looking up a tool by name inside
get_toolis a high-frequency operation and linear scanning of all tools for every tool invocation wastes CPU time. A hashed lookup eliminates this overhead entirely.📊 Measured Improvement:
We built a benchmark using
timeitacross 10,000 executions iterating through a mix of first, middle, last, and non-existent tools in the tools list:PR created automatically by Jules for task 16068724223843316924 started by @badMade
