Is this skill safe to use on production applications?

Yes, it performs a defensive, read-only audit that does not modify or interact with the application beyond scanning for exposed credentials.

Who should use this skill?

It's built for those conducting authorized security assessments of web applications to identify credentials that have accidentally leaked into client-side code.

Why it matters

Scan web applications you are authorized to assess for accidentally exposed credentials, API keys, tokens, and sensitive configuration files that have leaked into client-visible JavaScript, HTML attributes, comments, or publicly accessible source files.

Outcomes

What it gets done

Parse JavaScript bundles and HTML for hardcoded credentials and API keys

Inspect meta tags, data attributes, and HTML comments for leaked secrets

Enumerate and retrieve publicly accessible config, source, and deployment files

Generate a structured report of all discovered sensitive exposures

Overview

Client-Side Secret & Sensitive-File Exposure Audit

A defensive, read-only audit workflow that scans web applications for credentials and secrets leaked into client-visible surfaces. It examines JavaScript code, HTML attributes (meta, data-*), source comments, and publicly accessible configuration or deployment files to find credentials that anyone with a browser can extract. Use this when you are authorized to assess a web application and need to verify that no secrets have accidentally shipped to the browser.

What it does

This skill performs a defensive, read-only audit of web applications to identify credentials and secrets that have leaked into client-visible code. It scans JavaScript bundles, HTML attributes (meta, data-*), source comments, and publicly accessible configuration or deployment files for credentials that anyone with a browser or curl can extract.

Inputs and outputs

You provide the target web application URL and authorization confirmation. The skill scans for credentials exposed in client-side JavaScript, HTML markup, comments, or publicly served source/config/deployment files that were never meant to be public.

Who it's for

This skill is built for those conducting authorized assessments of web applications to find credentials that have leaked into client-side code. It addresses the specific problem class where modern web apps ship large amounts of code and configuration to browsers, creating a surface where secrets can accidentally become public.

Source README

Modern web apps ship a lot of code and config to the browser. When credentials
leak into that client-visible surface - hardcoded in JavaScript, tucked into HTML
meta/data-* attributes or comments, or served as raw source/config/deploy
files that were never meant to be public - anyone can read them with curl and a
browser. This skill is a defensive, read-only workflow for finding that class
of exposure on a web app you are authorized to assess.
