Greptile Overview

Greptile Summary

Optimized get_app() function by caching the current working directory path.

• Created new _cwd() helper function decorated with @once to cache the result of Path.cwd() on first call
• Replaced direct str(Path.cwd()) call with _cwd() in get_app() to avoid repeated filesystem calls
• This is a targeted performance improvement for a frequently-called function where the working directory doesn't change during execution

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• Simple, focused performance optimization using an existing proven pattern (@once decorator). The change only caches an immutable value (cwd) that doesn't change during process execution, making it safe and correct.
• No files require special attention
