Axum (Rust) web framework patterns for production APIs: routers/extractors, state, middleware, error handling, tracing, graceful shutdown, and testing

Elite UX agency capabilities for designing products users intuitively love. Use when creating user journeys, conducting UX research, designing flows, testing with Playwright, performing design critiques, building wireframes, writing microcopy, accessibility audits, competitive analysis, or any product design work. Triggers on UX, user journey, user experience, flow design, usability, design critique, persona creation, emotional mapping, or product design discussions.

Generate actionable, dependency-ordered task lists from implementation plans usingSpecification-Driven Development (SDD) methodology. Use when creating executablework breakdown, task lists, or executing the /tasks command.This skill analyzes design artifacts (plan, contracts, data models, test scenarios)and generates a sequenced task list with parallel execution markers. Tasks followTDD (test-first) and contract-first principles, with clear dependencies and file paths.Triggered by: /tasks command, user request for "task list", "work breakdown","implementation steps", or "what tasks do I need to complete?".

Essential testing patterns for any project.Use when: writing tests, setting up testing, or fixing test issues.Triggers: "test", "testing", "unit test", "write tests".

Write and run Go tests using the built-in testing package with table-driven tests, subtests, and mocking via interfaces. Use when writing Go tests or setting up test infrastructure.

Create ticket directories with 1-definition.md from PRD and planning docs. Use this skill to initialize new tickets with self-contained context, relationships, testing draft, and expectations.

Executes behavioral API tests by spinning up the service and making real HTTP requests. Validates status codes, response structure, and data correctness.

Programmatic browser automation using Playwright MCP server. Use when building Claude Code tools or applications that need web automation, testing, scraping, or browser interaction. Provides structured accessibility-based automation without screenshots or vision models.

Use this skill when building AI voice agents with the ElevenLabs Agents Platform. This skill covers the complete platform including agent configuration (system prompts, turn-taking, workflows), voice & language features (multi-voice, pronunciation, speed control), knowledge base (RAG), tools (client/server/MCP/system), SDKs (React, JavaScript, React Native, Swift, Widget), Scribe (real-time STT), WebRTC/WebSocket connections, testing & evaluation, analytics, privacy/compliance (GDPR/HIPAA/SOC 2), cost optimization, CLI workflows ("agents as code"), and DevOps integration. Prevents 17+ common errors including package deprecation, Android audio cutoff, CSP violations, missing dynamic variables, case-sensitive tool names, webhook authentication failures, and WebRTC configuration issues. Provides production-tested templates for React, Next.js, React Native, Swift, and Cloudflare Workers. Token savings: ~73% (22k → 6k tokens). Production tested.Keywords: ElevenLabs Agents, ElevenLabs voice agents, AI voice agent

Test-Driven Development (TDD) using Vitest and TypeScript. Use when the user requests help with TDD, writing tests before code, test-first development, Vitest test setup, TypeScript testing patterns, unit testing, integration testing, or following the Red-Green-Refactor cycle with Vitest.

Guide experienced developers through RED phase of TDD cycle - writing failing tests and verifying expected failures

Database optimization, security audit, and performance analysis for MyDetailArea Supabase/PostgreSQL. Provides safe query optimization, RLS policy review, index recommendations, and migration strategies with extreme caution and rollback plans. Use when optimizing database performance, auditing security, or creating safe migrations. CRITICAL - All recommendations require validation and testing before production.

Testing patterns, pyramid, TDD

Full-stack development expertise covering backend, frontend, database, DevOps, and testing domains

Guide for writing high-quality acceptance criteria and acceptance tests using industry-standard BDD (Behavior-Driven Development) and ATDD (Acceptance Test-Driven Development) practices. Use this skill when creating acceptance criteria for user stories, writing Gherkin scenarios, or implementing acceptance test specifications following Given-When-Then format.

Execute complete build pipeline with dead code detection, formatting, linting, type checking, testing, and production build. Use when the user mentions building, running the full pipeline, checking code quality, or preparing for deployment. Auto-triggers on phrases like "build the project", "run all checks", "prepare for production", or "validate code quality".

ONLY trigger this skill when the user EXPLICITLY asks for MCP-based testing:**Required triggers (ALL must mention "MCP" explicitly):**- "test connector with mcp"- "test mcp connector"- "test [provider] with mcp"- "use mcp to test [provider]"- "run mcp connector test"- "mcp test for [provider]"**DO NOT trigger for:**- Generic "test the connector" requests (use stackone run / test_actions instead)- "test [provider]" without explicit MCP mention- Regular validation or testing requests- Any testing that doesn't explicitly mention MCPThis skill builds a REAL agent with Claude Agent SDK that sends natural language prompts to evaluate if action descriptions are agent-friendly. It's more intensive than regular testing and should only be used when explicitly requested.
