Use this skill when writing unit tests with Jest or Vitest, implementing mocking strategies, configuring test runners, or improving test coverage. Triggers on Jest, Vitest, describe/it/expect, mocking, vi.fn, jest.fn, snapshot testing, test coverage, and any task requiring JavaScript/TypeScript unit testing.
Use this skill when planning user research, conducting usability tests, creating journey maps, or designing A/B experiments. Triggers on user interviews, usability testing, user journey maps, A/B test design, survey design, persona creation, card sorting, tree testing, and any task requiring user experience research methodology or analysis.
Use this skill when building dbt models, designing semantic layers, defining metrics, creating self-serve analytics, or structuring a data warehouse for analyst consumption. Triggers on dbt project setup, model layering (staging, intermediate, marts), ref() and source() usage, YAML schema definitions, metrics definitions, semantic layer configuration, dimensional modeling, slowly changing dimensions, data testing, and any task requiring analytics engineering best practices.
Use this skill when implementing chaos engineering practices, designing fault injection experiments, running game days, or improving system resilience. Triggers on chaos engineering, fault injection, Chaos Monkey, Litmus, game days, resilience testing, failure modes, blast radius, and any task requiring controlled failure experimentation.
Use this skill when writing Cypress e2e or component tests, creating custom commands, intercepting network requests, or integrating Cypress in CI. Triggers on Cypress, cy.get, cy.intercept, cypress component testing, custom commands, fixtures, cypress-cucumber, and any task requiring Cypress test automation.
Use this skill when conducting authorized penetration tests, vulnerability assessments, or security audits within proper engagement scope. Triggers on pentest methodology, vulnerability scanning, OWASP testing guide, Burp Suite, reconnaissance, exploitation, reporting, and any task requiring structured security assessment within authorized engagements or CTF competitions.
Report-only QA testing. Systematically tests a web application and produces a structured report with health score, screenshots, and repro steps — but never fixes anything. Use when asked to "just report bugs", "qa report only", or "test but don't fix". For the full test-fix-verify loop, use /qa instead.
Use when you need to review, improve, or write Java unit tests — including migrating from JUnit 4 to JUnit 5, adopting AssertJ for fluent assertions, structuring tests with Given-When-Then, ensuring test independence, applying parameterized tests, mocking dependencies with Mockito, verifying boundary conditions (RIGHT-BICEP, CORRECT, A-TRIP), leveraging JSpecify null-safety annotations, or eliminating testing anti-patterns such as reflection-based tests or shared mutable state.

Systematically testing web applications for broken access control vulnerabilities including privilege escalation, missing function-level checks, and insecure direct object references.
Autonomous iterative experimentation loop for any programming task. Guides the user through defining goals, measurable metrics, and scope constraints, then runs an autonomous loop of code changes, testing, measuring, and keeping/discarding results. Inspired by Karpathy's autoresearch. USE FOR: autonomous improvement, iterative optimization, experiment loop, auto research, performance tuning, automated experimentation, hill climbing, try things automatically, optimize code, run experiments, autonomous coding loop. DO NOT USE FOR: one-shot tasks, simple bug fixes, code review, or tasks without a measurable metric.
Find and own a defensible market position. Use when messaging sounds like competitors, conversion is weak despite awareness, repositioning a product, or testing positioning claims. Includes Crawl-Walk-Run rollout methodology and the word change that improved enterprise deal progression.
Lead complex software implementation, architecture decisions, and reliable delivery across any modern technology stack. Use when you need pragmatic architecture tradeoffs, technical plan creation from ambiguous requirements, code quality improvements, production-safe rollout strategies, observability setup, or senior engineering judgment on maintainability, testing, and operational reliability.
