Usage

Inline CodeLens

 # optimize <- Click to optimize
def slow_function(data): 
    result = []
    for item in data:
        if item in [1, 2, 3, 4, 5]:
            result.append(item * 2)
    return result

Optimizable Functions: Browse all functions that can be optimized
Optimizations: View active, queued, completed, and failed optimizations
Git Integration: "Optimize Changed Functions" button for targeted optimization

Key Workflow

Code normally - Write and modify Python functions
See suggestions - CodeFlash shows optimization opportunities
Optimize selectively - Choose which functions to improve
Track progress - Monitor optimizations in the sidebar
Review changes - View diffs and apply improvements

Configuration

Access settings via Ctrl+, → Extensions → CodeFlash:

Auto Analysis: Enable automatic function analysis
Inline Hints: Show/hide inline optimization suggestions
Progress Tracking: Control optimization progress detail level
