+You are an expert release manager for a Yarn 4 monorepo who uses the npm CLI for quick version bumps and patch releases.
+
+# Versioning With npm CLI
+
+## Policy
+- Prefer small, fast patch releases for incremental work.
+- Treat new components and minor fixes as patch releases when they are additive and low-risk.
+- Reserve minor/major only for notable feature waves or breaking changes.
+
+Note: While the repo supports Changesets for broader release coordination, this rule documents the npm CLI flow for quick iterations.
+
+## What Counts As “Small”
+- Additive components (new UI or form wrappers) without breaking changes
+- Bug fixes, perf tweaks, a11y refinements, copy/docs updates
+- Internal refactors that don’t change public APIs
+
+## Pre-flight
+- Clean working tree: no uncommitted changes
+- On a release-worthy branch (e.g., `main`)
+- Build and tests pass: `yarn build && yarn test`
+
+## Patch Bump (Single Workspace)
+For the published package `@lambdacurry/forms`:
+
+```bash
+# Bump version with custom message
+npm version patch -w @lambdacurry/forms -m "Add DateField component and fix TextField accessibility"
+
+# The -m flag creates the git commit automatically with your message
+# No need for separate git add/commit steps
+
+## Post-version Steps
+After running `npm version patch`, you'll need to:
+
+1. **Return to top level**: `cd ../..` (if you're in the package directory)
+2. **Update lockfile**: `yarn install` to update `yarn.lock` with the new version
+3. **Commit lockfile**: `git add yarn.lock && git commit -m "Update yarn.lock for @lambdacurry/forms vX.Y.Z"`
+
+This ensures the lockfile reflects the new package version and maintains consistency across the monorepo.
+```
+
+Guidelines:
+- Keep the summary one line and human-readable.
+- Examples: "Add DateField; fix TextField aria; smaller bundle".
+- This updates `packages/components/package.json` and creates a normal commit without tags.
+
+## Open PR and Merge
+- Push your branch and open a PR.
+- When the PR merges into `main`, GitHub CI publishes the package. No manual tagging or `npm publish` needed.
+
+## Minor / Major (When Needed)
+- Minor: larger feature sets or notable additions across multiple components
+  ```bash
+  npm version minor -w @lambdacurry/forms -m "Add comprehensive form validation and new field types"
+  ```
+- Major: any breaking change (API removals/renames, behavior changes)
+  ```bash
+  npm version major -w @lambdacurry/forms -m "Breaking: rename onSubmit to handleSubmit; remove deprecated props"
+  ```
+
+## Summary Message Tips
+- Keep it under ~100 chars; list 2–3 highlights separated by semicolons
+- Focus on user-visible changes first; include critical fixes
+- Avoid noisy implementation detail; link to PR/issue in the PR body
+
+## Coordination With Changesets
+- Use this npm CLI flow for quick, low-risk patches.
+- For multi-package changes, coordinated releases, or richer changelogs, prefer Changesets (`yarn changeset`) and follow the existing repo workflow.

+# Repository Guidelines
+
+## Project Structure & Module Organization
+- `apps/docs`: Storybook docs, examples, and UI tests.
+- `packages/components`: Source for `@lambdacurry/forms` (`src/**`, built to `dist/`).
+- `types/`: Shared ambient types.
+- `.changeset/`: Versioning and release metadata.
+- Root configs: `biome.json`, `turbo.json`, `tsconfig.json`, `package.json` (Yarn workspaces).
+
+## Build, Test, and Development Commands
+- `yarn dev`: Run all workspace dev tasks via Turbo.
+- `yarn build`: Build all packages/apps.
+- `yarn serve`: Serve built Storybook (`apps/docs`).
+- `yarn test`: Run workspace tests (Storybook test-runner in `apps/docs`).
+- `yarn format-and-lint` | `:fix`: Check/auto-fix with Biome.
+- Per workspace (examples):
+  - `yarn workspace @lambdacurry/forms build`
+  - `yarn workspace @lambdacurry/forms-docs dev`
+
+## Coding Style & Naming Conventions
+- Indentation: 2 spaces; max line width 120; single quotes (Biome enforced).
+- TypeScript + React (ES modules). Keep components pure and typed.
+- Filenames: kebab-case (e.g., `text-field.tsx`, `data-table-filter/**`).
+- Components/Types: PascalCase; hooks: camelCase with `use*` prefix.
+- Imports: organized automatically (Biome). Prefer local `index.ts` barrels when useful.
+
+## Testing Guidelines
+- Framework: Storybook Test Runner (Playwright under the hood) in `apps/docs`.
+- Naming: co-locate tests as `*.test.tsx` near stories/components.
+- Run: `yarn test` (CI-like) or `yarn workspace @lambdacurry/forms-docs test:local`.
+- Cover critical interactions (forms, validation, a11y, filter behavior). Add stories to exercise states.
+
+## Commit & Pull Request Guidelines
+- Commits: short imperative subject, optional scope, concise body explaining rationale.
+  - Example: `Fix: remove deprecated dropdown select`.
+- PRs: clear description, linked issues, screenshots or Storybook links, notes on testing.
+- Required checks: `yarn format-and-lint` passes; build succeeds; tests updated/added.
+- Versioning: when changing published package(s), add a Changeset (`yarn changeset`) before merge.
+
+## Security & Configuration
+- Node `22.9.0` (`.nvmrc`) and Yarn 4 (`packageManager`).
+- Do not commit secrets. Keep large artifacts out of VCS (`dist`, `node_modules`).
+- PR previews for Storybook are published via GitHub Pages; verify links in PR comments.
+
+## Cursor Rules Review
+- `.cursor/rules/react-typescript-patterns.mdc` (Always): React 19 + TS conventions, refs, props/types, naming.
+- `.cursor/rules/ui-component-patterns.mdc` (Always): Radix + Tailwind 4 + CVA patterns, a11y, performance.
+- `.cursor/rules/form-component-patterns.mdc`: Remix Hook Form + Zod wrappers, errors, server actions.
+- `.cursor/rules/storybook-testing.mdc`: Storybook play tests, router stub decorator, local/CI flows.
+- `.cursor/rules/monorepo-organization.mdc`: Imports/exports, package boundaries, Turbo/Vite/TS paths.
+- `.cursor/rules/versioning-with-npm.mdc`: npm CLI version bumps (patch-first), CI publishes on merge.
+
+When to review before starting work
+- Building/refactoring UI components: react-typescript-patterns + ui-component-patterns.
+- Form-aware components or validation: form-component-patterns.
+- Writing/updating stories or interaction tests: storybook-testing.
+- Moving files, changing exports/imports, adding deps/build entries: monorepo-organization.
+- Complex UI (data table, Radix primitives, variants): ui-component-patterns for a11y/perf.
+
+Quick checklist
+- Files/names: kebab-case files; PascalCase components; named exports only.
+- Types: explicit props interfaces; React 19 ref patterns; organize imports (Biome).
+- Forms: Zod schemas, proper messages, `fetcher.Form`, show `FormMessage` errors.
+- Tests: per-story decorators, semantic queries, three-phase play tests; run `yarn test`.
+- Monorepo: no cross-package relative imports; verify `exports`, TS `paths`, Turbo outputs.
