An open-source framework that prevents AI agents from breaking your codebase.
Skill Claude CodeCodex
Canonical Mandu agent workflow. Use first in Mandu projects before direct source edits so Codex, Claude Code, Gemini CLI, and other agents follow the same context -> plan -> apply -> verify -> repair loop.
Skill Claude CodeCodex
React composition patterns for Mandu applications. Use when designing Island components, managing shared state, or building reusable component APIs. Triggers on compound components, context providers, boolean props, or component architecture tasks.
Skill Claude CodeCodex
Production deployment patterns for Mandu applications.
Skill Claude CodeCodex
File-system based routing for Mandu. Use when creating pages, API routes, layouts, or dynamic routes. Triggers on tasks involving app/ folder, page.tsx, route.ts, layout.tsx, [id], [...slug], or URL patterns.
Skill Claude CodeCodex
Architecture guard system for Mandu. Use when checking layer dependencies, enforcing architecture rules, or validating file locations. Triggers on tasks involving architecture, layers, dependencies, or guard commands.
Skill Claude CodeCodex
Island Hydration pattern for Mandu. Use when creating interactive components, client-side state, or partial hydration. Triggers on tasks involving "use client", client.tsx, useState, useEffect, Island, or hydration.
Skill Claude CodeCodex
Performance optimization patterns for Mandu applications. Use when optimizing slot handlers, Island components, bundle size, or Bun runtime. Triggers on tasks involving async/await, Promise.all, lazy loading, caching, or performance.
Skill Claude CodeCodex
Security best practices for Mandu applications. Use when implementing authentication, authorization, input validation, or protecting against common vulnerabilities. Triggers on guard, auth, CSRF, XSS, or security tasks.
Skill Claude CodeCodex
Mandu Slot API for writing business logic. Use when creating API handlers, implementing authentication guards, adding lifecycle hooks, or working with request/response context. Triggers on tasks involving Mandu.filling(), ctx.ok(), ctx.error(), .guard(), .get(), .post(), or slot files.
Skill Claude CodeCodex
Tailwind CSS v4 integration and Island styling patterns for Mandu Framework.
Skill Claude CodeCodex
Testing patterns for Mandu applications. Use when writing unit tests, integration tests, or E2E tests. Triggers on test, spec, Bun test, Playwright, or testing tasks.
Skill Claude CodeCodex
UI component library integration and accessibility patterns.
Skill Claude CodeCodex
A Korean-language workflow for scaffolding REST API endpoints with CRUD operations, authentication, and uploads. REST APIs let software exchange data over web requests, while CRUD means create, read, update, and delete.
Skill Claude CodeCodex
A Mandu project workflow for creating a new feature by analysing requirements, adding page or API routes, defining data contracts, and generating starter code. An API is a program interface that lets software exchange data; an Island is a client-side UI component in this project.
Skill Claude CodeCodex
A troubleshooting workflow for Mandu web projects, covering build failures, blank pages, API errors, broken styles, and other common problems.
Skill Claude CodeCodex
A production deployment guide for Mandu applications, covering the steps from building and testing to running the app with Docker, CI/CD, and nginx. Docker packages an application and its dependencies into a repeatable container.
Skill Claude CodeCodex
A reference guide to core Mandu concepts, including server-rendered pages, interactive islands, API handlers, access guards, shared API schemas, and server-side data loaders. Server-side rendering creates page HTML on the server before sending it to the browser.
Skill Claude CodeCodex
A guide for Mandu Guard, a system that enforces allowed software layers and imports. It also explains six architecture presets, such as Feature-Sliced Design and Clean Architecture.
Skill Claude CodeCodex
A code-quality checking guide built around linting, type checking, and architecture checks. Linting finds issues such as unused variables, while type checking catches incorrect data types.
Skill Claude CodeCodex
A specification-first workflow for creating features, resources, routes, or API endpoints. It creates a contract describing the expected structure before generating the code, then verifies the result.
Skill Claude CodeCodex
A deployment workflow for Mandu projects that combines build, validation, SEO-file generation, and a production rehearsal. It stops the process when an early check fails and asks for approval before the real deployment.
Skill Claude CodeCodex
A routing guide for choosing among Mandu's many coding-agent tools and workflow instructions. Mandu is a project system with tools for creating features, checking edits, debugging, refactoring, and deploying.
Skill Claude CodeCodex
A session-start workflow for quickly understanding a software project’s current state. It gathers the project summary, recent commits, documentation list, architecture rules, errors, and suggested next steps.
Skill Claude CodeCodex
A safety procedure for large or difficult-to-reverse code changes, such as migrations and broad refactors. It creates a restore point, opens a transaction, verifies the edits, and either keeps or rolls them back.
