System Documentation

What problem does it solve?

This Skill helps you diagnose slow Python startup by showing exactly which imports and sub-imports take the most time.

Core Features & Use Cases

  • Import-time profiling: Produces a detailed timing breakdown of nested imports for a chosen import statement.
  • Waterfall HTML report: Generates an interactive HTML waterfall visualization to pinpoint bottlenecks quickly.
  • Use Case: When importing spatialdata (or related modules) feels sluggish, you can profile import spatialdata or a specific entry point like from spatialdata import SpatialData to identify the most expensive dependency chain.

Quick Start

Run: profimp --html "import spatialdata" > /tmp/profimp.html
