Use this skill when creating API contracts, validating request/response payloads, generating form schemas, adding input validation to Server Actions or route handlers, or ensuring type safety across client-server boundaries. Trigger terms include zod, schema, validation, API contract, form validation, type inference, runtime validation, parse, safeParse, input validation, request validation, Server Action validation.

Best practices when developing in Ruby codebases

Automatically extract reusable patterns from Claude Code sessions and save them as learned skills for future use.

Creates Playwright test scripts from natural language user flow descriptions. This skill should be used when generating E2E tests from scenarios, converting user stories to test code, recording user flows, creating test scripts from descriptions like "user signs up and creates project", or translating acceptance criteria into executable tests. Trigger terms include playwright test, e2e flow, user scenario, test from description, record flow, user journey, test script generation, acceptance test, behavior test, user story test.

Review documentation changes for compliance with the Metabase writing style guide. Use when reviewing pull requests, files, or diffs containing documentation markdown files.

Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation

Scaffolds comprehensive testing setup for Next.js applications including Vitest unit tests, React Testing Library component tests, and Playwright E2E flows with accessibility testing via axe-core. This skill should be used when setting up test infrastructure, generating test files, creating test utilities, adding accessibility checks, or configuring testing frameworks for Next.js projects. Trigger terms include setup testing, scaffold tests, vitest, RTL, playwright, e2e tests, component tests, unit tests, accessibility testing, a11y tests, axe-core, test configuration.

Instinct-based learning system that observes sessions via hooks, creates atomic instincts with confidence scoring, and evolves them into skills/commands/agents.

Use this skill when discussing UI components, design systems, frontend implementation, or component architecture. Guides thinking about Atomic Design methodology - atoms, molecules, organisms - and promotes component reuse over creation. Triggers on UI/frontend discussions, "what components do we need?", "should I create a new component?", or design system questions.

AI agent development with LangChain, CrewAI, AutoGen, and tool integration patterns.

Use this skill when discussing code changes, implementation work, feature status, or when starting/completing development tasks. Reminds about Jira issue tracking discipline - always having an issue in progress before writing code, transitioning to done, and creating Subtasks for unexpected scope. Triggers when users mention implementing features, writing code, or checking on work status.

Use when you have a spec or requirements for a multi-step task, before touching code

Multi-agent specification review and iteration. Writes specs via spec-writer, reviews with AI personas, and iterates until approved.

Work with MongoDB (document database, BSON documents, aggregation pipelines, Atlas cloud) and PostgreSQL (relational database, SQL queries, psql CLI, pgAdmin). Use when designing database schemas, writing queries and aggregations, optimizing indexes for performance, performing database migrations, configuring replication and sharding, implementing backup and restore strategies, managing database users and permissions, analyzing query performance, or administering production databases.

Git-powered state awareness - track file changes, session context, decisions, and work history. Query what happened in previous sessions and during current session. Auto-activates for state queries and before duplicating work.

Sets up comprehensive GitHub Actions CI/CD workflows for modern web applications. This skill should be used when configuring automated lint, test, build, and deploy pipelines, adding preview URL comments on pull requests, or optimizing workflow caching. Use when setting up continuous integration, deployment automation, GitHub Actions, CI/CD pipeline, preview deployments, or workflow optimization.

Create and maintain technical documentation including READMEs, API docs, architecture decision records (ADRs), and user guides. Use this skill when writing project documentation, documenting APIs, recording architectural decisions, creating how-to guides, or establishing documentation standards. Triggers on "documentation", "readme", "docs", "adr", "architecture decision", "api docs", "user guide", "document this".

This skill should be used when installing and configuring markdown editor functionality using @uiw/react-md-editor. Applies when adding rich text editing, markdown support, WYSIWYG editors, content editing with preview, or text formatting features. Trigger terms include markdown editor, rich text editor, text editor, add markdown, install markdown editor, markdown component, WYSIWYG, content editor, text formatting, editor preview.
