This skill should be used when the user asks about "WebSocket in Bun", "real-time communication", "Bun.serve websocket", "ws server", "socket connections", "pub/sub", "broadcasting messages", "WebSocket upgrade", or building real-time applications with Bun
Handles Chainlink CCIP requests and never signs or broadcasts. It sends one-node GET diagnosis to chainlink-nop-skill. It sends ACE policy design to chainlink-ace-skill. Pool and message mechanics stay here. It applies to route, token, message-status, and lane lookups, fee estimates, cross-chain transfers and messaging, sender and receiver contracts, extraArgs V3, Fast Transfers, CCT token pools, and CCIP monitoring.
Guide for contributing to Nuxt UI. Provides component structure patterns, Tailwind Variants theming, Vitest testing conventions, and MDC documentation guidelines. Use when creating new components, reviewing component PRs, modifying existing components, writing tests, or creating documentation in this codebase.
Query Coralogix continuous-profiling data with the `cx profiling` CLI — find which services use the most CPU or memory, which profile types a service has, what profiles can be filtered by, when usage spiked and which pod or version caused it, and which code paths and functions a service spends its CPU or memory on (flame graphs). Use when the user asks "which services use the most CPU", "top memory consumers", "what is service X spending CPU on", "hot functions", "flame graph for a service", "why is this service using so much CPU", "memory allocations by function", "CPU spike by pod", "which version increased CPU", "continuous profiling", "profiling data", or wants to explore profiles of a service. For how much CPU or memory a service or pod uses and whether it is saturated, use `cx-service-catalog` instead.
Write JavaScript (Node.js v22) for Factorial Code processes and modules — the async main() entry point with module.exports = { main }, fcode.context.parameters, fcode.import(), datastore/storage/env helpers, auto-installed dependencies, and return-value formats. Use when creating or editing .js process or module code for Factorial Code (fcode).
Author Factorial Code process input-parameter schemas (parametersSchema.json) — every supported input type and validation option, with a complete annotated sample. Use when creating or editing a parametersSchema.json, or defining a Factorial Code (fcode) process's input parameters or form fields.
Integrate Firecrawl into application code whenever a product, agent, or workflow needs web data inside the app — web search, live search results, page scraping, structured extraction, or browser interaction. Use when building any feature that needs data from the web in code, even if the user does not mention Firecrawl explicitly and only describes wanting web data, website content, search, scraping, or interaction in an application. Trigger for Firecrawl requests, "fire girl" shorthand, and generic app-level web-data needs that should map to `/scrape`, `/search`, or `/interact`. Do not use this skill for one-off terminal-only web tasks during the current session; use `firecrawl/cli` for those.
Expert guidance on the Google Agent Development Kit (ADK) for Python. Use this skill when the user asks about building agents, using tools, streaming, callbacks, tutorials, deployment, or advanced architecture with the Google ADK in Python.
Animation components and utilities for Remotion video projects. Use when building Remotion compositions with text animations, gradient transitions, particle effects, 3D scenes, or staggered motion effects. Provides example bits (complete compositions) and reusable components that can be installed via jsrepo
Look up information in SigNoz documentation. Make sure to use this skill whenever the user asks "how do I", "where in the docs", "what does the docs say about", "find docs for", or otherwise needs reference material on SigNoz instrumentation, OpenTelemetry setup, self-hosted deployment, API endpoints, auth headers, or troubleshooting steps, even if they don't say the word "docs" explicitly. Docs lookup only; for actions inside SigNoz, the agent will pick the matching `signoz-*` action skill.
Every product will be AI-powered. The question is whether you'll build it right or ship a demo that falls apart in production. This skill covers LLM integration patterns, RAG architecture, prompt engineering that scales, AI UX that users trust, and cost optimization that doesn't bankrupt you. Use when: keywords, file_patterns, code_patterns.
Generates API documentation using OpenAPI/Swagger specifications with interactive documentation, code examples, and SDK generation. Use when users request "API documentation", "OpenAPI spec", "Swagger docs", "document API endpoints", or "generate API reference".
Rebuild, install, and reload the private Remotion Canvas Capture unpacked Chrome extension. Use when the extension needs to be restored after a Codex worktree was deleted, rebuilt after source changes, moved to its durable install directory, or reloaded in Chrome or Chrome Canary.
Entry point for any CometChat task on any platform. Detects the framework + UI Kit version (React, Angular, iOS, Android, React Native, Flutter), then routes to that family's skills — for a NEW integration or a change to an existing one. Triggers: 'add chat', 'add cometchat', 'add chat to my app', 'add calling', 'change something in my chat', 'my chat is already set up', 'add a feature to the chat', 'add chat to my android app', 'integrate cometchat android', 'add chat to my ios app', 'integrate cometchat ios', 'add chat to my swift app', 'migrate my app to cometchat', 'migrate from sendbird', 'migrate from getstream / stream', 'replace sendbird / stream chat with cometchat'.
Iterative, confirmation-driven workflow for building Factorial Code processes and modules end to end — plan-and-confirm, discovery scripts, incremental implementation validated with the run_code MCP tool, exposing processes as MCP tools, plus security and error-handling practices. Use when asked to build, automate, or integrate something on Factorial Code (fcode) and you need the recommended working method.
Use the Factorial Code CLI (fcode) for local development and cloud sync — the pull → add → run → push flow, the local webhook/forms server, workspace versions and aliases, and the workspace config files (metadata.json, settings.json, variables). Use when running fcode commands, testing a process locally, syncing to the cloud, cloning every App of a development team, inspecting or resolving differences between local and cloud, or configuring a process's webhook, Factorial Action (the `factorial` block — form, UI trigger, agent tool, backend), or version settings.
Write Python 3.13 for Factorial Code processes and modules — the main() entry point, fcode.context.parameters, fcode.import_module(), datastore/storage/env helpers, PEP 8 / snake_case, auto-installed dependencies, and return-value formats. Use when creating or editing .py process or module code for Factorial Code (fcode).
Take a spec, issue, branch, or pull request to a reviewed pull request: implement and publish it, then run review-and-resolve rounds, each step in a fresh subagent, resuming wherever the pull request stands. Use only when the user says the explicit phrase "Finish it".
Run measurement-led React and Next.js performance audits for waterfalls, bundle size, RSC/server-client boundaries, hydration mismatch, rerender churn, script cost, and slow page interactions. Use when the user needs help diagnosing or refactoring a slow React UI, App Router route, heavy client component, or Next.js page with excess JavaScript or weak client/server boundaries. Triggers on: React perf, Next.js perf, waterfall, bundle size, hydration, rerender, client component too heavy, slow route, React profiler, web vitals
Bootstrap and toolchain guidance for three.js applications using npm, Vite/Webpack/Rollup, bare ESM import maps, and TypeScript. Covers canonical import paths for `three` core versus `three/addons/` (examples/jsm re-exports), version alignment with https://threejs.org/docs/, and fixing "module not found" for loaders and controls. Use when scaffolding a new 3D project, migrating bundler, or debugging resolution of addons—do not use for rendering API details (see threejs-renderers) or asset loading logic (see threejs-loaders).
Zod schema validation best practices for type safety, parsing, and error handling. This skill should be used when defining z.object schemas, using z.string validations, safeParse, or z.infer. This skill does NOT cover React Hook Form integration patterns (use react-hook-form skill) or OpenAPI client generation (use orval skill).
Use when you need to design, review, or improve REST APIs with Spring Boot — including HTTP methods, resource URIs, status codes, DTOs, versioning, deprecation and sunset headers, content negotiation (JSON and vendor media types), ISO-8601 instants in DTOs, pagination/sorting/filtering, Bean Validation at the boundary, idempotency, ETag concurrency, HTTP caching, error handling, security, contract-first OpenAPI (OpenAPI Generator), controller advice, and problem details for errors. This should trigger for requests such as Review Java code for Spring Boot REST API; Apply best practices for Spring Boot REST API in Java code; Design Spring Boot REST controllers and DTOs; Add Problem Details error responses in Spring Boot REST; Improve pagination validation or idempotency in Spring APIs.

Guide for building, configuring, and deploying microfrontends on Vercel. Use this skill when the user mentions microfrontends, multi-zones, splitting an app across teams, independent deployments, cross-app routing, incremental migration, composing multiple frontends under one domain, microfrontends.json, @vercel/microfrontends, the microfrontends local proxy, or path-based routing between Vercel projects. Also use when the user asks about shared layouts across projects, navigation between microfrontends, fallback environments, asset prefixes, or feature flag controlled routing
Design or refactor project structure around the right boundary unit: feature, shared layer, route segment, or workspace package. Use when a repo feels scattered, a team needs naming/import conventions, or the user must choose between type-based, feature-based, framework-colocated, and workspace layouts. Triggers on: file organization, folder structure, project structure, reorganize repo, feature folders, shared vs feature code, where should this file live, apps/packages split, and project layout refactor.
Address the review findings posted on an Entire trail: fetch the trail's open findings, fix the code, and resolve them on the trail. Use when the user gives a trail URL or number and asks to address, fix, or resolve its findings or review comments. Not for local diff review — that is the `review` 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.
