Migrate webpack, Vite, create-react-app (CRA/CRACO), or Vue CLI projects to Rsbuild.

Migrate tsc or tsup library projects to Rslib.

Migrate ESLint or other linters to Rslint. Use when asked to replace ESLint flat config, lint scripts, VS Code ESLint settings, inline directives, rules, presets, plugins, or lint dependencies with Rslint equivalents.

Migrate Jest or Vitest projects to Rstest. Use when replacing Jest/Vitest config, scripts, APIs, setup, mocks, snapshots, coverage, or projects with @rstest/core; auditing test discovery parity; resolving config-loading or dependency-version failures; or diagnosing migration-time build, runtime, memory, and performance regressions caused by Rstest's Rsbuild/Rspack execution model, dependency bundling, runtime-mocked module graphs, assets, logs, or worker pools.

Rsbuild best practices for config, CLI workflow, type checking, bundle optimization, assets, and debugging. Use when writing, reviewing, or troubleshooting Rsbuild projects.

Use when upgrading a Rsbuild 1.x project to v2, including dependency and configuration updates.

Use when analyzing Rspack/Webpack bundles from local rsdoctor-data.json and producing evidence-based optimization recommendations.

Rslib best practices for config, CLI workflow, output, declaration files, dependency handling, build optimization and toolchain integration. Use when writing, reviewing, or troubleshooting Rslib projects.

Opinionated Rslib recommendations for modern JS/TS npm package design covering pure ESM, strict TypeScript, explicit exports, small stable APIs, pragmatic dependencies, accurate sideEffects, correct declarations, package validation, provenance, README.md, and AGENTS.md. Use when the user wants to make a JS/TS package more modern, check whether the current package setup is healthy, review package.json/exports/types/dependencies/docs/release readiness, or apply a modern library baseline.

Rspack best practices for config, CLI workflow, type checking, CSS, bundle optimization, assets and profiling. Use when writing, reviewing, or troubleshooting Rspack projects.

Helps Rspack users and developers debug crashes or deadlocks/hangs in the Rspack build process using LLDB. Use this Skill when users encounter "Segmentation fault" errors during Rspack builds or when the build progress gets stuck.

Diagnose and optimize Rspack optimization.splitChunks configuration. Use this when a user wants better production chunking, safer chunks: "all" defaults, fewer duplicated modules, better long-term caching, cacheGroups design help, maxSize tuning, or debugging over-fetch caused by name and forced chunk merging.

Comprehensive guide and toolkit for diagnosing Rspack build issues. Quickly identify where crashes/errors occur, or perform detailed performance profiling to resolve bottlenecks. Use when the user encounters build failures, slow builds, or wants to optimize Rspack performance.

Use when upgrading a Rspack 1.x project to v2, including dependency and configuration updates.

Rspress best practices for config, CLI workflow, content organization, frontmatter, MDX, themes, i18n, search, static assets, deployment, and debugging. Use when writing, reviewing, or troubleshooting Rspress documentation sites.

Customize Rspress themes using CSS variables, Layout slots, component wrapping, or component ejection. Use when a user wants to change the look and feel of an Rspress site, override theme components, add custom navigation/sidebar/footer content, inject global providers, or modify the default Rspress theme in any way. Also use when a user mentions theme/index.tsx, Layout slots, BEM class overrides, or rspress eject.

Generate and maintain description frontmatter for Rspress documentation files (.md/.mdx). Use when a user wants to add SEO descriptions, improve search engine snippets, generate llms.txt metadata, prepare docs for AI summarization, or batch-update frontmatter across an Rspress doc site. Also use when adding new documentation pages to an Rspress project — every new doc file needs a description.

Generate or maintain Rspress documentation for a project. Use whenever the user wants to create a new Rspress v2 docs site, add docs for user-facing feature work or PRs, maintain a dedicated Rspress docs project in a monorepo, or prevent stale Rspress v1 scaffolds/version drift before documentation work. For full v1-to-v2 migration, hand off to the rspress-v2-upgrade skill.

Migrate Rspress projects from v1 to v2. Use when a user asks to upgrade Rspress, follow the v1-to-v2 guide, update configs/themes, or validate the upgrade.

Rstest best practices for config, CLI workflow, test writing, mocking, snapshot testing, DOM testing, coverage, multi-project setup, CI integration, performance and debugging. Use when writing, reviewing, or troubleshooting Rstest test projects.

Debug Rstest startup, build, runtime, logging, and memory problems systematically. Use when Rstest is slower than Jest/Vitest or a previous baseline; when runner/build/tests/CLI wall disagree; when setup/collect or Node module loading dominates; when mocked modules still enter bundles; when experimental bundle coverage or asset utilization needs inspection; or when dependency bundling, assets, pools, isolation, logs, or memory need evidence-based tuning.

Set up or migrate Storybook to use the Rsbuild builder. Handles fresh setup for React, Vue 3, HTML, Web Components, and React Native Web, migration from webpack5 or Vite frameworks, and integrations with Rslib, Modern.js, and Rspack. Use when asked to add Storybook, migrate Storybook to Rsbuild, configure rsbuildFinal, or integrate Storybook with Rslib/Modern.js/Rspack.
