Testing & Security

Browser testing, web scraping, and UI validation using Playwright MCP. Use this skill when you need to test Streamlit apps, validate web interfaces, test responsive design, check accessibility, or automate browser interactions through MCP tools.

Advanced test reporting, quality dashboards, predictive analytics, trend analysis, and executive reporting for QE metrics. Use when communicating quality status, tracking trends, or making data-driven decisions.

Systematic test design with boundary value analysis, equivalence partitioning, decision tables, state transition testing, and combinatorial testing. Use when designing comprehensive test cases, reducing redundant tests, or ensuring systematic coverage.

Build effective test automation strategy using the test pyramid and practical patterns. Use when planning automation approach, selecting tools, or optimizing test suites.

Advanced visual regression testing with pixel-perfect comparison, AI-powered diff analysis, responsive design validation, and cross-browser visual consistency. Use when detecting UI regressions, validating designs, or ensuring visual consistency.

WCAG 2.2 compliance testing, screen reader validation, and inclusive design verification. Use when ensuring legal compliance (ADA, Section 508), testing for disabilities, or building accessible applications for 1 billion disabled users globally.

Using AI agents as force multipliers in quality work. Use when designing autonomous testing systems, implementing PACT principles, or scaling quality engineering with intelligent agents. Core skill for all QE agents in the fleet.

Configuring Snowflake connections using connections.toml (for Snowflake CLI, Streamlit, Snowpark) or profiles.yml (for dbt) with multiple authentication methods (SSO, key pair, username/password, OAuth), managing multiple environments, and overriding settings with environment variables. Use this skill when setting up Snowflake CLI, Streamlit apps, dbt, or any tool requiring Snowflake authentication and connection management.

Chaos engineering principles, controlled failure injection, resilience testing, and system recovery validation. Use when testing distributed systems, building confidence in fault tolerance, or validating disaster recovery.

Test for security vulnerabilities using OWASP principles and security testing techniques. Use when conducting security audits, testing authentication/authorization, or implementing security practices.

Developing, testing, and deploying Streamlit data applications on Snowflake. Use this skill when you're building interactive data apps, setting up local development environments, testing with pytest or Playwright, or deploying apps to Snowflake using Streamlit in Snowflake.

Strategic regression testing with test selection, impact analysis, and continuous regression management. Use when verifying fixes don't break existing functionality, planning regression suites, or optimizing test execution for faster feedback.

Regulatory compliance testing for GDPR, CCPA, HIPAA, SOC2, PCI-DSS and industry-specific regulations. Use when ensuring legal compliance, preparing for audits, or handling sensitive data.

Conduct context-driven code reviews focusing on quality, testability, and maintainability. Use when reviewing code, providing feedback, or establishing review practices.

Test application performance, scalability, and resilience. Use when planning load testing, stress testing, or optimizing system performance.

Cross-browser, cross-platform, and cross-device compatibility testing ensuring consistent experience across environments. Use when validating browser support, testing responsive design, or ensuring platform compatibility.

Use when users need help generating safe, tested POSIX shell commands from natural language descriptions. Guides users through command generation, safety validation, and execution workflows using Caro best practices

Guide for using the ct (CommonTools) binary to interact with charms, recipes, and the Common Fabric. Use this skill when deploying recipes, managing charms, linking data between charms, or debugging recipe execution. Triggers include requests to "deploy this recipe", "call a handler", "link these charms", "get data from charm", or "test this recipe locally".

Monitor dbt execution using the dbt Artifacts package. Use this skill when you need to track test and model execution history, analyze run patterns over time, monitor data quality metrics, or enable programmatic access to dbt execution metadata across any dbt version or platform.

Apply context-driven testing principles where practices are chosen based on project context, not universal "best practices". Use when making testing decisions, questioning dogma, or adapting approaches to specific project needs.
