What problem does it solve?

When debugging Pyre/Pysa false negatives, it can be hard to locate where taint flow is dropped. This Skill helps you compare two Pysa analysis outputs to identify exactly where taint flow is lost, enabling precise remediation.

Core Features & Use Cases

  • Compare two Pysa output directories to locate divergence in taint propagation.
  • Extract and correlate issue handles from static analysis URLs to guide investigation.
  • Provide a structured workflow that surfaces the precise call chain where taint propagation breaks.

Quick Start

Provide two Pysa output directories and an issue URL to begin locating where taint flow is lost.
