Squash: Caido Request Minimizer Plugin

Squash is a Caido plugin that adds a right-click context menu option to minimize an HTTP request. When activated, it launches a background job that:

• Sends the original request
• Iteratively removes query parameters, form fields, JSON, and headers (including individual cookies)
• Compares responses to identify invariant behavior
• Retains only fields necessary to preserve the original response
• Sends the minimized request to a new Replay tab for review and testing

Installation

• Download plugin_package.zip from https://github.com/evanconnelly/squash/releases
• Add to Caido: https://docs.caido.io/guides/plugins
