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`.

Use when implementing state management with PlatformVmStore for complex components requiring reactive state, effects, and selectors.

This skill automates database backups using the database-backup-automator plugin. It creates scripts for scheduled backups, compression, encryption, and restore procedures across PostgreSQL, MySQL, MongoDB, and SQLite. Use this when the user requests database backup automation, disaster recovery planning, setting up backup schedules, or creating restore procedures. The skill is triggered by phrases like "create database backup", "automate database backups", "setup backup schedule", or "generate restore procedure".

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.

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.

Use when implementing state management with PlatformVmStore for complex components requiring reactive state, effects, and selectors.

This skill should be used when the user wants to view, display, or show a file stored in the CRM database. This is an orchestration skill that combines downloading from the database and opening with the OS default application. Triggers on requests like "show me the contract from CRM", "display the image from the database", "view the PDF for company X", or "open the attachment from the database".

This skill uses the stored-procedure-generator plugin to create production-ready stored procedures, functions, triggers, and custom database logic. It supports PostgreSQL, MySQL, and SQL Server. Use this skill when the user asks to "generate stored procedure", "create database function", "write a trigger", or needs help with "database logic", "optimizing database performance", or "ensuring transaction safety" in their database. The skill is activated by requests related to database stored procedures, functions, or triggers.

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.

Event-driven architecture patterns including message queues, pub/sub, event sourcing, CQRS, and sagas. Use when implementing async messaging, distributed transactions, event stores, command query separation, RabbitMQ, Kafka, SQS, or NATS integration.
