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

Use the globally installed rsdoctor-agent CLI from @rsdoctor/agent-cli only after a real rsdoctor-data.json path exists. Keep analysis read-only unless the user explicitly asks for install/config setup.

.rsdoctor-analysis-cache.json entries before doing new work.rsdoctor-data.json fast: user-provided path, then dist/rsdoctor-data.json, output/rsdoctor-data.json, static/rsdoctor-data.json, .rsdoctor/rsdoctor-data.json, then one bounded rg --files search excluding node_modules and .git. Treat manifest.json only as an index.rsdoctor-agent analysis commands, do not run the Analysis Gate, and either ask for the data path or run the Generation Gate below only when setup/generation is required.rsdoctor-agent data-fetch command: verify global @rsdoctor/agent-cli with npm view @rsdoctor/agent-cli version and rsdoctor-agent --version; install latest only if missing/outdated, a version-related error occurs, or the user asks to refresh.Performance rules: parallelize independent checks, cache only derived facts (dataFile, dataFileMtime, pluginName, pluginVersion, dependency/config/plugin modification times), and invalidate cache when paths disappear, modification times change, the user asks to refresh, or cached values fail. Speculative plugin checks must not trigger generation; use them only after confirming the data file is missing.
Identify pluginName (@rsdoctor/rspack-plugin or @rsdoctor/webpack-plugin) and determine pluginVersion from local files first: package.json, lockfile, then node_modules/<plugin>/package.json; use pnpm why / npm ls only as fallback.
Use this exact if/else decision tree; do not merge branches:
if pluginName is missing:
install/register the matching Rsdoctor plugin, then configure output.mode='brief' and output.options.type=['json']; build with RSDOCTOR=true only
else if pluginVersion is unknown:
resolve pluginVersion first; if still unknown, configure output.mode='brief' and output.options.type=['json']; build with RSDOCTOR=true only
else if pluginVersion >= 1.5.11:
do not edit plugin config just for JSON; build with RSDOCTOR_OUTPUT=json and RSDOCTOR=true if needed
else: # pluginVersion < 1.5.11
MUST configure output.mode='brief' and output.options.type=['json']; build with RSDOCTOR=true only
Preflight every build command: RSDOCTOR_OUTPUT=json is allowed only in the pluginVersion >= 1.5.11 branch. For missing, unknown, or < 1.5.11, it is forbidden. For < 1.5.11, generating rsdoctor-data.json requires the plugin config below:
output: {
mode: 'brief',
options: {
type: ['json'],
},
}
Default Evidence Set:
| Summary key | Evidence source | Bounds |
|---|---|---|
buildCost | build summary | filtered fields only |
assetsTop | top assets by raw/gzip size | fixed Top-N |
packagesTop | top packages by gzip size | fixed Top-N; avoid full packages list pages |
duplicatePackages | E1001 duplicate package summary | first-pass summary only |
crossChunkPackages | E1002 cross-chunk duplication summary | first-pass summary only |
retainedModulesTop | tree-shaking retained-modules --limit 10 | filtered fields only; no --compact |
Scope rules:
rsdoctor-agent for bundle data access only after rsdoctor-data.json exists; prefer parallel independent fetches; bound output with --filter, pagination, and --limit.tree-shaking retained-modules --emitted-only --category side-effects --limit 10 with narrow --filter for side-effects investigations.tree-shaking retained-modules with --emitted-only, bounded --category, --sort gzipSize, --limit, and narrow --filter; do not pass --compact.tree-shaking summary only as fallback for missing fields or aggregate context. Treat tree-shaking bailout-reasons as high-volume; run it only when explicitly requested and pass target --modules (max 100).5k tokens, 500 KB raw output, or a few hundred transcript lines, stop broad fetching and switch to targeted compact queries.Output format:
For Top-N insights, prefer a table: Name | Volume/Time | Count | Recommendation.
Recovery rules:
rsdoctor-data.json missing: do not run rsdoctor-agent; ask for the data path or run Generation Gate, then use the matching install reference if setup is needed.rsdoctor-agent.query reports unknown tool: run list and use a catalog tool name, or switch to direct <group> <subcommand> mode.install, build, global CLI installation, version checks, or rsdoctor-agent... inside sandbox. Run Rsdoctor CLI setup and data-fetch commands outside sandbox so they can access project files and dependencies normally.References: commands/options references/command-map.md; install/config/data location references/install-rsdoctor.md, references/install-rsdoctor-rspack.md, references/install-rsdoctor-webpack.md, references/install-rsdoctor-common.md; raw data fields references/rsdoctor-data-types.md; common patterns references/common-analysis-patterns.md.
