Help users integrate Portaly Payment hosted checkout, including merchant setup, subscription plans (monthly, yearly with 12-month deferred disbursement, one-time), checkout sessions, recurring renewal callbacks, and callback verification. Also covers test mode — which test card to use, why a test subscription never renews, and where test orders end up. Trigger when the user mentions Portaly Payment, creator subscription, wants to add subscription-based checkout to their application, wants the list of unfinished or failed checkouts (the dashboard's 未完成結帳 / 付款失敗) to follow up or reconcile, or is troubleshooting a Portaly test payment, test card, sandbox order, or a renewal callback that never arrived
Parallel thinking with six enforced perspectives, based on Edward de Bono's Six Thinking Hats® method. Examine one decision through sequential passes for facts, feelings, risks, benefits, alternatives, and synthesis without blending them. Use when a decision is being made too quickly or from one angle, when everyone agrees suspiciously quickly, when a discussion mixes emotions with data, or for "six hats", "thinking hats", "look at this from every angle", or "structured devil's advocate". Do NOT use for analytical work like debugging, code review, or implementation tasks.
Symfony UX frontend stack -- decision tree and orchestrator for choosing between Stimulus, Turbo, TwigComponent, LiveComponent, UX Icons, and UX Map. Use when the user is unsure which tool fits, wants to combine multiple UX packages, or asks a general frontend architecture question in Symfony. Also trigger when the user asks "which UX package should I use", "how to make this interactive", "should I use Stimulus or LiveComponent", "how to structure my Symfony frontend", "what is the difference between Turbo and LiveComponent", "should this be a Frame or a LiveComponent", "how do these UX packages work together", "what is the Symfony way to do frontend". Do NOT trigger when the user clearly names a specific tool (stimulus, turbo, twig-component, live-component, ux-icons, ux-map) -- defer to the specialized skill instead.
Comprehensive security and correctness audit of a branch's changes. Use for thermo nuclear, thermonuclear, or deep review requests, or branch/PR diff audits focused on bugs, breaking changes, security issues, devex regressions, and feature-gate leaks.
Voice agents represent the frontier of AI interaction - humans speaking naturally with AI systems. The challenge isn't just speech recognition and synthesis, it's achieving natural conversation flow with sub-800ms latency while handling interruptions, background noise, and emotional nuance. This skill covers two architectures: speech-to-speech (OpenAI Realtime API, lowest latency, most natural) and pipeline (STT→LLM→TTS, more control, easier to debug). Key insight: latency is the constraint. Hu

Forced Analogy / Structural Transplant — map the problem onto a structurally similar system from a distant domain (immune system, air-traffic control, restaurant kitchen, jazz ensemble) and transfer its mechanisms back. Use when a solution works but feels derivative, when the industry playbook is exhausted, or when a system in nature or another trade already solves this shape of problem. Triggers include "analogy", "forced analogy", "how would a hospital/kitchen/airport handle this", "transplant from another industry", "structurally similar system". Do NOT use for analytical work like debugging, code review, or implementation tasks

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
