Generate exhaustively complete and accurate Datadog Software Catalog entity YAML files (v3 schema) by examining project source code and interviewing engineers. Use when engineers need to create or update entity.datadog.yaml files for services, datastores, queues, APIs, or systems. Triggers include: "create entity yaml", "generate service catalog entry", "document this project in datadog", "create service definition", "add to software catalog", or any request involving Datadog entity/service documentation. Supports all v3 entity kinds: service, datastore, queue, api, system. Fetches existing Datadog data via API. Validates against official JSON schema. Merges with existing definitions. Outputs to .datadog/ directory.

This skill enables Claude to automatically generate comprehensive documentation for existing database schemas using the database-documentation-gen plugin. It is triggered when the user requests database documentation, ERD diagrams, or a data dictionary. The plugin supports multiple database engines and generates documentation that includes ERD diagrams, table relationships, column descriptions, indexes, triggers, stored procedures, and interactive HTML documentation. Use this skill when you need to document existing database schemas for team onboarding, architectural reviews, or data governance purposes. The trigger terms include "database documentation", "ERD diagram", "data dictionary", and `/db-docs`.

This skill enables Claude to generate end-to-end (E2E) tests for web applications. It leverages Playwright, Cypress, or Selenium to automate browser interactions and validate user workflows. Use this skill when the user requests to "create E2E tests", "generate end-to-end tests", or asks for help with "browser-based testing". The skill is particularly useful for testing user registration, login flows, shopping cart functionality, and other multi-step processes within a web application. It supports cross-browser testing and can be used to verify the responsiveness of web applications on different devices.

Automatically save and restore development context to minimize cognitive load when resuming work. Use when switching tasks, taking breaks, or returning after interruptions. Captures mental state, file locations, and next steps. Designed for ADHD developers with high context-switching costs.

Design audits and submission preparation. Use when reviewing designs for quality, checking accessibility compliance, or preparing for App Store submission.

This skill enables Claude to automatically scan for XSS (Cross-Site Scripting) vulnerabilities in code. It is triggered when the user requests to "scan for XSS vulnerabilities", "check for XSS", or uses the command "/xss". The skill identifies reflected, stored, and DOM-based XSS vulnerabilities. It analyzes HTML, JavaScript, CSS, and URL contexts to detect potential exploits and suggests safe proof-of-concept payloads. This skill is best used during code review, security audits, and before deploying web applications to production.
