Best practices for Zod schema validation and type inference in TypeScript applications.
Earthly E2E validation for YAML schema contracts. TRIGGERS - schema validation, YAML schema, schema contracts, regenerate types.
POC validation patterns to catch issues before committing to long-running ML experiments. TRIGGERS - fail-fast, POC validation, preflight check, experiment validation, schema validation, gradient check, sanity check, smoke test.
Validation patterns using fp-ts with error accumulation, form validation, and API input validation
Use when validating golden dataset quality. Runs schema checks, duplicate detection, and coverage analysis to ensure dataset integrity for AI evaluation.
Evaluates Next.js routes and outputs optimal revalidate settings, cache tags for ISR, SSR configurations, or streaming patterns. This skill should be used when optimizing Next.js caching strategies, configuring Incremental Static Regeneration, planning cache invalidation, or choosing between SSR/ISR/SSG. Use for Next.js caching, revalidation, ISR, cache tags, on-demand revalidation, or rendering strategies.
End-to-end form handling with react-hook-form, Zod schemas, validation patterns, error messaging, field arrays, and multi-step wizards. Use for complex forms, validation architecture, autosave, field dependencies. Activate on "form validation", "react-hook-form", "Zod", "form error", "multi-step form", "wizard". NOT for simple HTML forms, backend validation only, or non-React frameworks.
Validate code quality, test coverage, performance, and security. Use when verifying implemented features meet all standards and requirements before marking complete.
Automates form validation testing by submitting invalid data and capturing error states using Playwright browser automation. Use when you need to "test form validation", "check validation errors", "test invalid inputs", "verify error messages", or perform comprehensive form testing. Triggers on validation testing requests, QA workflows, or form compliance checks. Works with web forms, input fields, and validation frameworks across any web application.
Validate quality before completing tasks. Performs verification checks, testing, and quality assurance before marking work complete.
