Create or repair local Docker Compose services, Dockerfiles, mounts, networking, and readiness checks. Use when container configuration is the deliverable; ordinary container commands and production deployment are separate concerns
Migrate legacy Salesforce UI stacks onto modern LWC — Aura → LWC conversion completeness verification and Lightning Out Beta → Lightning Out 2.0 host-page migration. TRIGGER on \"verify Aura to LWC migration completeness\", \"migrate Lightning Out Beta to LO 2.0\", \"upgrade $Lightning.use() to <lightning-out-application>\", \"replace hardcoded LO tokens with OAuth PKCE\", \"write an LO 2.0 host page\", or an external Lightning Out page that stopped rendering; also `.cmp`/`.js-meta.xml` files alongside LWC. DO NOT TRIGGER for the initial Aura-to-LWC conversion (use experience-aura-lwc-migrate), a React-to-LWC migration, or building a new LWC (use experience-lwc-design-generate).
CRITICAL — Do NOT write code yourself. Route ALL code generation through this Skill. This is the MANDATORY entry point. When a user asks for any code, file, project, or feature (生成代码/write code, 写函数/write a function, 创建模块/create a module, 开发项目/develop a project, 实现功能/implement a feature, 写一个XX/make an XX, 做一个XX/build an XX), or mentions CodeArts/码道, you MUST invoke this Skill first. Under NO circumstances may you skip this Skill and write code directly. Even if you think "this is faster" or "this is a simple task" — DO NOT skip.
Collaborative design exploration that authors the Design & Rationale section of the one unified docs/specs/ spec. Triggers: 'brainstorm', 'ideate', 'explore options', or /ideate. Default is a one-pass design preamble; the deep rung gates the 2-3 approach divergent loop and the discover bridge. Do NOT use for task decomposition (that is /plan, which adds Decomposition to the same doc) or code review.
Investigates a single PostHog error tracking issue end-to-end. Use when the user provides an issue ID or pastes an issue URL (`/error-tracking/<id>`) and wants to understand the error — who it affects, what triggers it, when it started, whether it correlates with a release, browser, OS, or feature flag, and what the next step should be. Pulls aggregated metrics, sample exception events, segment breakdowns, linked replays, and synthesizes a hypothesis-grade summary in one pass
Expose local HTTP, HTTPS, and TLS applications to the public internet through localhost.run SSH tunnels. Use when the user wants to share a locally running app, demo work in progress, test webhooks, access a local server from a remote device, set up a Custom Domain, tunnel non-HTTP protocols, or troubleshoot an existing localhost.run tunnel. Triggers on phrases like "expose my localhost", "make my local server public", "share my dev server", "tunnel my local app", "ngrok alternative", or any localhost.run reference.
Guides agents through complete, maintainable MoonBit bindings for C/C++ libraries, from upstream source surveys through vendoring, safe API design, documentation tests, and ASan validation. Use when creating or hardening MoonBit native FFI bindings, wrapping C APIs, vendoring C sources into native-stub, or turning a C library into a MoonBit package.
Use before any bulk edit, migration, standardization, or redesign—including splitting a large file or module and refactoring for agents or readability—before adding a guard, linter, hook, or constraint against a class of bugs, and before retrying a fix for the same symptom. It checks the hypothesis, mechanism, scope, and applicable facts before implementation; the result is one recommended approach, its boundary, and a verifiable sign of success. Also use when a decision relies on an unverified cause, external fact, or metric. Do not use for choosing a product task, finding edge cases, or making a small agreed-upon change.
Use Obscura for lightweight headless browsing, web scraping, and CDP automation. Trigger when users mention Obscura, want a lighter Chrome replacement for AI agents, need `obscura fetch` or `obscura scrape` commands, want to run `obscura serve`, need Playwright or Puppeteer to connect to Obscura over Chrome DevTools Protocol, or need a safe local development workflow such as Vite plus hostc plus Obscura because localhost is blocked by Obscura's SSRF protections
This skill should be used when the user asks to implement Phaser 4 game code, create or edit scenes, add players, enemies, scoring, collectibles, movement, shooting, animations, input, physics behavior, game objects, or complete gameplay features in TypeScript.
PowerShell vs. Git Bash/MSYS2 shell detection and cross-shell compatibility on Windows. Proactively activate for: (1) detecting whether a script runs under PowerShell, pwsh, Git Bash, or cmd, (2) shell-specific path handling, (3) MSYS_NO_PATHCONV when calling Windows binaries from Git Bash, (4) PowerShell from Git Bash and vice versa, (5) line-ending differences (CRLF vs. LF), (6) environment variable differences (env: VAR vs. VAR vs. percent VAR percent), (7) calling PowerShell scripts (.ps1) from bash and bash scripts from PowerShell, (8) profile loading differences. Provides shell-detection one-liners, path-conversion helpers, environment-variable portability patterns, and cross-shell invocation recipes.
General React fundamentals - components and JSX, props and state, the core hooks (useState/useEffect/useRef/useMemo/useCallback/useContext), composition, conditional and list rendering, and controlled inputs. The canonical "depends on React" reference.
Cut a release from the Conventional Commits a repo already writes: derive the semver bump and a changelog from the commit range, bump the manifest, tag it, and publish a GitHub release, all behind a mandatory preview. Use when the user says "cut a release", "tag a version", "release this", "what's the next version", "generate a changelog", "ship v2", or "/releasekit". It never publishes to a package registry and never moves a published tag.
Use for Roblox multiplayer communication across the client-server boundary: designing RemoteEvent, UnreliableRemoteEvent, and RemoteFunction flows; validating client requests; handling replication-aware gameplay; applying rate limits and anti-exploit checks; reasoning about network ownership, server-authority patterns, Input Action System use in authoritative gameplay, and streaming-sensitive multiplayer correctness
Audit and propose fixes for a page's heading hierarchy and semantic outline — verify exactly one H1, logical H2-H6 nesting with no skipped levels, descriptive heading text, and HTML5 landmarks (article/section/nav/main/footer) — so the document outline is extractable. Module M7c. Feeds the Search SEO score (clean headings also support AI answer-block extraction, which is scored separately under M11).
createServerFn (GET/POST), validator (Zod or function), useServerFn hook, server context utilities (getRequest, getRequestHeader, setResponseHeader, setResponseStatus), error handling (throw errors, redirect, notFound), streaming, FormData handling, file organization (.functions.ts, .server.ts).

Emulated Sign in with Apple / Apple OIDC for local development and testing. Use when the user needs to test Apple sign-in locally, emulate Apple OIDC discovery, handle Apple token exchange, configure Apple OAuth clients, or work with Apple userinfo without hitting real Apple APIs. Triggers include "Apple OAuth", "emulate Apple", "mock Apple login", "test Apple sign-in", "Sign in with Apple", "Apple OIDC", "local Apple auth", or any task requiring a local Apple OAuth/OIDC provider.
Bootstrap agents for iOS, iPadOS, macOS, Swift, SwiftUI, SwiftData/Core Data, Swift Testing, Xcode build/test/debug, Simulator, App Intents, or XcodeBuildMCP work. Use before building, fixing, refactoring, QAing, or setting up Apple-platform repos, and when asked to load/install Ray's iOS skills or bootstrap iOS.
Maps and documents codebases of any size by orchestrating parallel subagents. Creates docs/CODEBASE_MAP.md with architecture, file purposes, dependencies, and navigation guides. Updates CLAUDE.md with a summary. Use when the user says "map this codebase", "cartographer", "/cartographer", "create codebase map", "document the architecture", "understand this codebase", or when onboarding to a new project. Automatically detects if map exists and updates only changed sections.
Map the load-bearing files, symbols, callers, and dependencies of an unfamiliar codebase before making changes. Use for architecture orientation, impact analysis, what-would-break questions, or finding callers. Uses CodeGraph when available and a dependency-free builtin fallback.
Dispatch implementation tasks to agent teammates in git worktrees from a prepared capsule, then settle the batch. Triggers: 'delegate', 'dispatch tasks', 'assign work', or /delegate. Compiles the batch with prepare, spawns teammates, submits their results with settle. Supports --fixes flag. Do NOT use for single-file changes or polish-track refactors.

Gathers real data from GitHub (via gh CLI), Linear (via zen-linear skill), Jira (via zen-jira skill), and Sentry (via zen-sentry skill). Renders a live HTML dashboard in Zenflow's built-in browser. Also runs automated actions: multi-model PR review, dependency audits, and bug triage.
Functional programming patterns with immutable data. Use when writing logic, data transformations, or encountering mutation bugs — including any feature request that builds, merges, filters, sorts, prices or otherwise reshapes records, lists, carts, orders or invoices, even when it never mentions immutability; load it alongside tdd for such changes, not instead of it. Covers immutability violations catalog, pure functions, composition, early returns, and options objects. Also use when composing Effect programs or reviewing Effect runtime boundaries in a project that already uses Effect. Do NOT over-apply heavy FP abstractions (monads, fp-ts) unless the project requires them.
Migrates apps from @coinbase/onchainkit to standalone wagmi/viem components. Handles provider replacement (OnchainKitProvider to WagmiProvider), wallet component replacement (Wallet/ConnectWallet to custom WalletConnect), and transaction component replacement. Use when the user says “migrate my onchainkit,” “replace onchainkit provider,” “migrate my wallet component,” “replace my onchainkit wallet,” “migrate my transaction component,” “remove onchainkit dependency,” or “move off onchainkit.”
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.
