Use when you want to add tracing, structured logging, or monitoring to your FrontMCP server. Covers OpenTelemetry instrumentation, vendor integrations (Coralogix, Datadog, Logz.io, Grafana), this.telemetry API for custom spans, structured JSON logging with sinks, and testing observability. Triggers: observability, telemetry, tracing, logging, monitoring, opentelemetry, otel, spans, datadog, coralogix, logz, grafana, winston, pino.
Tutorials, walkthroughs, and end-to-end examples for building FrontMCP servers. Use when you want a getting started guide, how to build a complete project, learn best practices, or follow a step-by-step example. Triggers: tutorial, walkthrough, how to build, getting started, learn FrontMCP.
Use when implementing authorization, access control, RBAC, ABAC, or ReBAC for tools, resources, prompts, or skills. Covers JWT claims mapping, authority profiles, and policy enforcement.
Pre-production audit and checklist for FrontMCP servers. Use before go-live to verify security hardening, performance checks, observability, monitoring, and health checks. Triggers: production ready, security audit, performance check, production checklist, hardening, go live.
Extend FrontMCP servers with external npm packages and libraries. Covers VectoriaDB for semantic search, and patterns for integrating third-party services into providers and tools. Use when adding search, ML, database, or external API capabilities beyond the core SDK.
Use when you want to write tests, run tests, add e2e tests, improve test coverage, test a tool, test a resource, or learn how to test any FrontMCP component. The skill for ALL testing needs.
Use when you need to deploy, build for production, containerize, or ship a FrontMCP server. Covers Vercel, Lambda, Cloudflare, Docker, edge runtime, serverless, bundle for CLI, and Node targets. Triggers: deploy, build for production, dockerize, serverless, go live.
Use when you want to configure auth, set up CORS, add rate limiting, throttle requests, manage sessions, choose transport, set HTTP options, add authentication, configure JWT, or set up OAuth. The skill for server CONFIGURATION.
ALWAYS use this skill when the user asks to build, modify, or audit a FrontMCP tool. Covers everything inside `@Tool({...})`: class and function-style tools, Zod input/output schemas with derived `execute()` types, dependency injection (`this.get` / `this.tryGet`), error handling (`this.fail`, MCP error classes), throttling (rate-limit / concurrency / timeout), auth providers (single / multi / vault), availability constraints (`availableWhen`), elicitation (`this.elicit`), interactive UI widgets via `@Tool({ ui })` (MCP Apps / SEP-1865 — including `.tsx` FileSource, CSP, `window.FrontMcpBridge`, host-detect `resourceMode`), annotations (`readOnlyHint` / `destructiveHint` / …), `examples` metadata, registration in `@App({ tools })`, and per-tool unit testing. Does NOT cover: - Read-only data exposed via a URI — use `create-resource` - Conversation templates / system prompts — use `create-prompt` - Multi-tool orchestration loops — use `create-agent` - Background work / pipelines — use `create-job` / `create-workflow` - Server-level config (transport, sessions, auth modes) — use `config` / `auth` Triggers: `@Tool`, ToolContext, tool decorator, MCP tool, snake_case tool name, inputSchema, outputSchema, ToolInputOf, ToolOutputOf, `@Tool({ ui })`, tool UI widget, MCP Apps widget, FileSource widget, `.tsx` widget, ui.csp, ui.resourceMode, window.FrontMcpBridge, tool annotations, readOnlyHint, destructiveHint, rate-limit tool, throttle tool, concurrency tool, tool timeout, this.fail, this.respond, this.fetch, this.notify, this.progress, this.elicit, ElicitationDisabledError, ToolContext.execute, this.get(TOKEN), this.tryGet, register tool in @App, tool examples metadata, availableWhen, missingAxes, `tool()` function builder, Tool.esm, Tool.remote, PublicMcpError, ResourceNotFoundError, MCP_ERROR_CODES, ui://widget.
Use when you want to create a tool, add a resource, build a prompt, write a provider, implement an adapter, add OpenAPI integration, create a plugin, agent, job, or workflow. The skill for BUILDING any FrontMCP component.
Domain router for project setup, scaffolding, and organization. Use this skill whenever someone asks to create a new FrontMCP project, set up an Nx monorepo, configure Redis or SQLite storage, organize project structure, compose multiple apps into one server, or manage the skills system. Also triggers for questions like 'how do I start', 'project layout', 'folder structure', 'add redis', 'set up database', or 'create a new app'.
Review a CodeRabbit PR comment and produce an action plan when prompted to analyze a review comment.
Use when you want to push real-time notifications into Claude Code sessions. Build webhook channels, chat bridges (WhatsApp, Telegram, Slack), agent completion alerts, job status notifications, or error forwarding. The skill for CHANNELS and NOTIFICATIONS.
A fixture skill with references and examples for E2E testing.
