Development
Review Go project architecture: package structure, dependency direction, layering, separation of concerns, domain modeling, and module boundaries. Use when reviewing architecture, designing package layout, evaluating dependency graphs, or refactoring monoliths into modules. Trigger examples: "review architecture", "package structure", "project layout", "dependency direction", "clean architecture Go", "module boundaries". Do NOT use for code-level style (use go-coding-standards) or API endpoint design (use go-api-design).
Write Go CLIs that manage processes and workloads — daemons, supervisors, job runners, deploy tools, anything that spawns or controls other processes. Use when writing, reviewing, or refactoring Go that handles OS signals, runs children via os/exec, fans out concurrent work, threads context for cancellation, returns exit codes, or builds a flag/cobra command surface. Covers the footguns the standard library makes easy to hit — SIGTERM vs Ctrl-C, SIGKILL-by-default children, orphaned process groups, pipe deadlocks, goroutine leaks, zombie reaping, and os.FindProcess lying about liveness. Triggers whenever the task touches process lifecycle, graceful shutdown, subprocess control, or concurrent workload supervision in Go — even if not named.
Build production realtime voice agents with Hume's Empathic Voice Interface (EVI): speech-to-speech sessions, empathic/prosodic response design, EVI 3 versus EVI 4-mini selection, WebSocket and SDK integration, tools/function calling, interruption/barge-in, turn-taking, transcripts/audio artifacts, pricing/limits, privacy, safety, consent, and QA.
Meta XR Interaction SDK (com.meta.xr.sdk.interaction.ovr) in Unity. Use when adding ANY interaction to a Meta VR or Horizon OS scene - grab (hand, distance, ray, touch), poke, teleport/locomotion, gaze, interactable UI canvases - when making an object grabbable, adding interactors to hands or controllers, creating an interaction rig, or baking interaction into a prefab or a scene whose rig loads elsewhere (dynamically, DontDestroyOnLoad, additively). Use the OVR backend unless the user explicitly asks for cross-platform. Covers QuickActionsAPI and OVRQuickActionsAPI as the default way to wire interactions, running them via unity-cli, an Editor script, or MCP, installation, and the undocumented behavior that source-reading or a Play-mode run is otherwise needed to discover.
Expert JavaScript developer specializing in modern ES2023+ features, Node.js runtime environments, and asynchronous programming patterns. This agent excels at writing clean, performant JavaScript code using the latest language features, optimizing runtime performance, and implementing scalable backend solutions with Node.js or Bun.

Covers route handler with fetchRequestHandler (GET + POST exports), TRPCProvider with QueryClientProvider, createTRPCOptionsProxy for RSC prefetching, HydrateClient/HydrationBoundary for hydration, useSuspenseQuery for Suspense, and server-side callers.
Use for new frontend applications, dashboards, games, creative websites, hero sections, and visually driven UI from scratch, or when the user explicitly asks for a redesign/restyle/modernization. Builds from clean, airy, high-taste, readable image-generated concept design with section-specific references, faithful implementation, and browser testing.
Expert in integrating payment gateways (Stripe, PayPal, Adyen) and designing PCI-compliant billing architectures. Use when implementing checkout flows, subscriptions, or payment processing. Triggers include "Stripe", "PayPal", "payment gateway", "checkout", "subscription billing", "PCI compliance", "payment processing".
Guides the design and assessment of RBAC and ABAC authorization models against the NIST RBAC model (Sandhu et al.) and NIST SP 800-162 (ABAC guide). Auto-invoked when designing role hierarchies, evaluating permission boundaries, implementing ABAC policy patterns, performing role mining, or preventing role explosion. Produces architecture recommendations with framework-grounded rationale.
Creates or updates the documentation (usually README.md, plus DEVELOPMENT.md for larger projects) directly in the source repository — as the source of truth. Sources are the existing docs, changelog files, Git commits since the last documentation update, and the source code. Use this skill when the user wants to write docs in a repo, update the README, document new features/changes, or bring the docs up to date. Trigger terms: create docs, update README, document, bring docs up to date, document changelog.
Review an experience, technical, plan, roadmap, or implementation doc from draft-experience, draft-technical, build-feature or draft-roadmap — you are the reviewer, not the author. Use when the user asks to review a plan, roadmap, design or experience document, or invokes /review-doc <feature>. Reads docs/<feature>/<DOC>.revN.md, writes <DOC>.revN.notes.md grounded in the product shape, the project's principles and the actual code, and iterates with the user until the doc is ready to become <DOC>.final.md.
Use the RPGJS Studio HTTP API to create or manage a 2D RPG game. Trigger this skill when Codex needs to CRUD maps, map events, database records, media assets, or general project settings in RPGJS Studio, especially when the task should be done through `curl` or another HTTP client with an API key and configurable base URL.
Enforces Built for Shopify (BFS) quality standards during Shopify app development. Use when building, reviewing, or auditing Shopify apps for BFS compliance, or when the user mentions Built for Shopify, BFS, app quality, or app store requirements.
GitHub Spec-Kit integration for constitution-based spec-driven development. 7-phase workflow (constitution, specify, clarify, plan, tasks, analyze, implement). Use when working with spec-kit CLI, .specify/ directories, or creating specifications with constitution-driven development. Triggered by "spec-kit", "speckit", "constitution", "specify", references to .specify/ directory, or spec-kit commands.
Spencer's house style for UIs. DO NOT INVOKE THIS SKILL UNLESS SPECIFICALLY ASKED. Use whenever Spencer asks for a frontend, page, screen, component, dashboard, app shell, modal, form, table, or any kind of web visual — including phrasings like "build a UI for X", "throw together a screen", "make a dashboard", "I need a quick app". Also use when starting a brand-new React project from scratch on this machine. Overrides any general "frontend-design" skill: Spencer dislikes the default shiny-AI aesthetic and wants tight, neutral, dense, system-font UIs that look like the due-diligence and security-review apps. If Spencer is editing an existing repo with a clearly different stack (e.g. Next.js with shadcn already wired up), follow that repo's conventions, but still apply Spencer's typography, density, and tone preferences from this skill.

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.
