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

Benchmark agent skills by generating eval cases, comparing skill-guided vs baseline runs, and recording artifacts under skills-test/{skill-name}.

Debug Rstest issues systematically, including performance regressions. First determine whether the slowdown is in build startup or test execution, then run controlled config or code experiments and compare before/after timings.

Create or update draft GitHub releases for the current project's main GitHub repository, then organize GitHub-generated release notes into user-friendly sections without rewriting release note items. Use for preparing, formatting, categorizing, creating, or updating GitHub release notes or draft releases, including optional highlights when the user asks for them.

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.

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

Migrate Jest or Vitest test suites and configs to Rstest. Use when asked to move from Jest/Vitest to Rstest, replace framework APIs with `@rstest/core`, translate test config to `rstest.config.ts`, or update test scripts and setup files for Rstest equivalents.

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.

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.

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

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.

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.
