The rules real projects give Cursor's agent, from .cursor/rules.
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

lucamezzaliraCursor rulelucamezzalira/mfe-skills/.cursor/rules/mfe-architecture.mdc
Provides micro-frontend architecture vocabulary, principles, and decisions framework grounded in Building Micro-Frontends (O'Reilly). Use when a user asks "should we use micro-frontends?", "how do I split my frontend into MFEs?", "what is a micro-frontend?", "help me define MFE boundaries", "should I use horizontal or vertical split?", "how do micro-frontends communicate?", or "is my architecture a distributed monolith?". Requires independent deployment or multi-team scaling as the explicit context. Does not activate for single-team frontend architecture, component design, or build tooling questions with no cross-team deployment angle.

lucamezzaliraCursor rulelucamezzalira/mfe-skills/.cursor/rules/mfe-boundary-review.mdc
Reviews and generates micro-frontend code against eight boundary rules from Building Micro-Frontends (O'Reilly), plus governance extensions for feature-flag scope, edge strategy, SSR ownership, and boundary fitness functions. Use when a user says "review my shell code", "is this a boundary violation?", "generate a Module Federation shell", "how do I mount this MFE?", "review my micro-frontend architecture", "set up event communication between MFEs", "create a new micro-frontend", "how should we use edge with MFEs?", "where should feature flags live?", or "how do I enforce boundaries in a monorepo?". Loads automatically when the user pastes shell integration code, Module Federation config, Single SPA registration, or Native Federation routes. Does not activate for component-level code within a single deployed unit, or for generic React, Vue, or Angular questions with no cross-team deployment angle.

edhoferdianCursor ruleedhoferdian/EEF/.cursor/rules/frontend-engineering-edho-ferdian.mdc
Authoring and configuration guidance for building React/Next.js frontend applications well from the start — component composition, UX/interaction recipes, Vite config, HeroUI setup, and AI-slop detection (see the Reference files table below for the full breakdown). A companion to language-code-review-edho-ferdian (which reviews code after it's written) — use this when DESIGNING or WRITING new frontend code, not when reviewing existing code. Trigger phrases: \"bagaimana cara structure component ini\", \"best practice React untuk X\", \"setup Vite untuk Y\", \"biar UI-nya gak keliatan AI banget\", \"kok hasil desainnya generic/template banget\", or when starting a new frontend feature.
Instruction files for Cursor's agent, kept in .cursor/rules/ as .mdc files.
A rule can apply only to files matching a pattern, or only when the agent asks for it. AGENTS.md always applies.
Copy the .mdc file into your project's .cursor/rules/ directory and adjust its globs.
Open a rule to see its discussion. Reports from people and their agents are coming.
