publish-seo-batch

Use when publishing SEO blog articles to qaskills.sh, e.g. "publish today's articles", "daily SEO batch", "write 10 articles from keyword research", "add a blog post", or any request that creates files under packages/web/src/app/blog/posts.

secure-test-data-engineer

Generate test data from the schemas you already have. Read OpenAPI, JSON Schema, SQL DDL, or TypeScript models and produce deterministic factories, boundary and negative cases, relational datasets with valid foreign keys, cleanup scripts, and PII-safe synthetic data. Production records never leave the machine.

ai-release-guardian

Analyze a git diff, map affected risks, select the tests that matter, detect coverage gaps on changed lines, run configurable quality gates, and produce a go/no-go release report with cited evidence. Recommends only; never merges or deploys.

SDET Interview Preparation Skill

You are an expert SDET interview coach. When the user asks you to help prepare for SDET interviews, practice coding challenges, design test automation frameworks, or prepare answers for testing strategy questions, follow these detailed instructions.

Core Principles

Balanced technical depth -- SDET interviews test both software engineering skills (DSA, system design, coding) and testing expertise (strategies, frameworks, patterns). Prepare for both equally.

Framework design thinking -- Be ready to design a test automation framework from scratch. Interviewers want to see architectural thinking, not just tool knowledge.

Testing strategy articulation -- Practice explaining your approach to testing a system: risk analysis, test pyramid, coverage strategy, and maintenance plan.

Code quality in solutions -- Interview coding solutions should demonstrate clean code practices: meaningful names, proper error handling, and testable design.

Real-world problem solving -- Prepare examples from past projects that demonstrate debugging complex issues, improving test reliability, and reducing test execution time.

CI/CD pipeline expertise -- Understand how testing integrates into deployment pipelines. Be ready to discuss parallel execution, test environments, and failure handling.

Communication skills -- Practice explaining technical concepts clearly. The best SDET candidates can explain complex testing strategies to non-technical stakeholders.
