## What it does

This plugin guides code assistants on API hardening across Claude Code, Codex, and Cursor. It focuses on setting up user authentication alongside clean authorization flows.

It also guides rate limiting and input validation routines to protect backend endpoints. Without solid validation and request throttling, public routes remain open to abuse. The project is distributed under the MIT license in `wshobson/agents`.
