building-mcp-servers
Guides creation of high-quality MCP (Model Context Protocol) servers that enable LLMsto interact with external services through well-designed tools. Use when building MCPservers to integrate external APIs or services, whether in Python (FastMCP) orNode/TypeScript (MCP SDK). Covers tool design, authentication, Docker deployment,and evaluation creation. NOT when consuming existing MCP servers (use the server directly).
complete-workflow-examples
Copy-paste hardened CI/CD workflows with SHA-pinned actions, minimal GITHUB_TOKEN permissions, OIDC authentication, and comprehensive security scanning for GitHub Actions.
playwright-e2e-testing
Playwright modern end-to-end testing framework with cross-browser automation, auto-wait, and built-in test runner
visual-verification
Visually verify implemented features work correctly before marking complete. Use when testing UI changes, verifying web features, or checking user flows work in the browser.
finishing-a-development-branch
Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup
ashby-api-guide
This skill should be used when the user asks about "Ashby API", "how to use Ashby tools", "Ashby authentication", "Ashby MCP tools", "what can I do with Ashby", or needs help understanding available Ashby operations. Provides complete API documentation and tool usage guidance.
testing
Write and manage tests using TDD with Pest (PHP), Vitest (React), and Playwright (E2E). Use when writingfeature tests, unit tests, component tests, or improving test coverage. EXCLUSIVE to testing-expert agent.
golang
Provides idiomatic Go programming expertise and best practices. Ensures clean, efficient, and maintainable code following official Go conventions. Specializes in concurrent programming patterns, interface design, error handling strategies, and performance optimization. Masters standard library usage and ecosystem integration.Use when: writing Go code (.go files), designing interfaces and struct types, implementing concurrent patterns (goroutines/channels), handling errors idiomatically, writing table-driven tests, creating Go modules, optimizing performance-critical code, managing dependencies with go.mod, implementing HTTP servers and clients, working with context propagation, or designing package APIs for public libraries.
policy-runner
Run policy-as-code checks (e.g., OPA/Conftest) based on the policy_plan. Use in Flow 2 and Flow 4.
render
Deploys web applications on Render with automatic builds, managed databases, and zero-config SSL. Use when deploying web services, static sites, or setting up managed infrastructure.
learning-adaptive-testing
adaptive-testing design for effective learning measurement.
supabase-expert
This skill should be used when the user asks to "create a Supabase table", "write RLS policies", "set up Supabase Auth", "create Edge Functions", "configure Storage buckets", "use Supabase with Next.js", "migrate API keys", "implement row-level security", "create database functions", "set up SSR auth", or mentions 'Supabase', 'RLS', 'Edge Function', 'Storage bucket', 'anon key', 'service role', 'publishable key', 'secret key'. Automatically triggers when user mentions 'database', 'table', 'SQL', 'migration', 'policy'.
e2e-playwright-diagnosis
Diagnose and resolve E2E test failures in Playwright. This skill should be used when E2E tests fail and need investigation, when Playwright test errors require root cause analysis, or when test failures need to be reproduced in the browser for debugging. Orchestrates MCP tools (Playwright, Chrome DevTools, Serena) and delegates code fixes to specialized agents.
e2e
Playwright E2E testing patterns with chrome-devtools MCP integration.Reference for integration tests, A11y validation, and visual regression.
authorization-endpoint-reviewer
Review test cases for Authorization Endpoint. Covers response_type=code, request parameters (scope, client_id, redirect_uri, state, nonce, prompt, display, max_age), and authorization response per OIDC Core 1.0 Section 3.1.2.
attacking-active-directory
Attack and enumerate Active Directory environments using Kerberos attacks (Kerberoasting, ASREPRoasting), credential dumping (DCSync, Mimikatz), lateral movement (PtH, PtT), and BloodHound analysis. Use when pentesting Windows domains or exploiting AD misconfigurations.
livekit-prompt-builder
Guide for creating effective prompts and instructions for LiveKit voice agents. Use when building conversational AI agents with the LiveKit Agents framework, including (1) Creating new voice agent prompts from scratch, (2) Improving existing agent instructions, (3) Optimizing prompts for text-to-speech output, (4) Integrating tool/function calling capabilities, (5) Building multi-agent systems with handoffs, (6) Ensuring voice-friendly formatting and brevity for natural conversations, (7) Iteratively improving prompts based on testing and feedback, (8) Building industry-specific agents (debt collection, healthcare, banking, customer service, front desk).
prompting-patterns
Automatically applies when engineering prompts for LLMs. Ensures proper prompt structure, templates, few-shot examples, context management, and injection prevention.
ln-621-security-auditor
Security audit worker (L3). Scans codebase for hardcoded secrets, SQL injection, XSS, insecure dependencies, missing input validation. Returns findings with severity (Critical/High/Medium/Low), location, effort, and recommendations.
vue-vite-testing
Comprehensive unit testing guide for Vue 3 + Vite projects using Vitest and Vue Test Utils. Use when writing or reviewing unit tests for Vue components, composables, Pinia stores, or TypeScript/JavaScript utilities in Vite-based projects. Covers test structure, best practices, mocking strategies, and Vue-specific testing patterns.
