Git Performance Issue Investigator

When the user needs to investigate performance issues in a Git repository by finding specific code changes, identifying responsible commits, and contacting authors. This skill is triggered by requests involving finding commits containing specific variables or code patterns, identifying earliest/introducing commits, extracting author information (name, email), and communicating about performance issues. It provides capabilities for searching Git history for specific code patterns using git log -S, retrieving full commit details with git show, extracting author metadata, and generating formatted communications using templates.
