+# Automated Workflows for Claude
+
+This file documents automated workflows that Claude should be aware of when working on this project.
+
+## NPM Package Publishing
+
+### @soroban/abacus-react Package
+
+**Status**: ✅ Fully configured and ready for automated publishing to npm
+
+**How to trigger a release**:
+```bash
+# Minor version bump (new features)
+git commit -m "feat(abacus-react): add new bead animation system"
+
+# Patch version bump (bug fixes)
+git commit -m "fix(abacus-react): resolve gesture detection issue"
+
+# Patch version bump (performance)
+git commit -m "perf(abacus-react): optimize bead rendering"
+
+# Major version bump (breaking changes)
+git commit -m "feat(abacus-react)!: change callback signature"
+```
+
+**Key Requirements**:
+- Must use `(abacus-react)` scope in commit message
+- Changes must be in `packages/abacus-react/` directory
+- NPM_TOKEN secret must be configured in GitHub repository settings
+
+**Workflow Details**:
+- **File**: `.github/workflows/publish-abacus-react.yml`
+- **Triggers**: Push to main branch with changes in `packages/abacus-react/`
+- **Steps**: Install deps → Build package → Run tests → Configure dual auth → Semantic release → Publish to npm + GitHub Packages
+- **Versioning**: Independent from monorepo (uses tags like `abacus-react-v1.2.3`)
+- **Publishing**: Dual publishing to both npm and GitHub Packages simultaneously
+
+**Current Status**:
+- ✅ Workflow configured for dual publishing
+- ✅ Semantic release setup for both registries
+- ✅ Package build/test passing
+- ✅ GitHub Packages authentication configured (uses GITHUB_TOKEN)
+- ⏸️ Awaiting NPM_TOKEN secret for actual npm publishing
+
+**What Claude should do**:
+When making changes to the abacus-react package:
+1. Use the proper commit format with `(abacus-react)` scope
+2. Remember this will trigger automatic npm publishing
+3. Ensure changes are meaningful enough for a version bump
+4. Reference this workflow in explanations to users
+
+## Storybook Deployment
+
+**Status**: ✅ Fully functional
+
+**Trigger**: Any push to main branch
+**Output**: https://antialias.github.io/soroban-abacus-flashcards/
+- Web app Storybook: `/web/`
+- Abacus React component Storybook: `/abacus-react/`
+
+## Semantic Release (Monorepo)
+
+**Status**: ✅ Configured to exclude abacus-react scope
+
+**Workflow**: Regular commits without `(abacus-react)` scope trigger monorepo releases
+**Versioning**: Affects root package.json version and creates GitHub releases
+
+## Claude Guidelines
+
+1. **Always check commit scope**: When working on abacus-react, use `(abacus-react)` scope
+2. **Be intentional**: Package releases are permanent - ensure changes warrant a version bump
+3. **Documentation**: Point users to CONTRIBUTING.md for full details
+4. **Status awareness**: Remember NPM_TOKEN is required for actual publishing
+5. **Testing**: Package tests must pass before publishing (currently has workaround for vitest config issue)
+
+## Quick Reference
+
+| Action | Commit Format | Result |
+|--------|---------------|---------|
+| Add abacus-react feature | `feat(abacus-react): description` | npm minor version bump |
+| Fix abacus-react bug | `fix(abacus-react): description` | npm patch version bump |
+| Breaking abacus-react change | `feat(abacus-react)!: description` | npm major version bump |
+| Regular monorepo feature | `feat: description` | monorepo minor version bump |
+| Regular monorepo fix | `fix: description` | monorepo patch version bump |

 - **fix**: Triggers a patch version bump (1.0.0 → 1.0.1)
 - **BREAKING CHANGE**: Triggers a major version bump (1.0.0 → 2.0.0)

+### Package-Specific Publishing
+
+The `@soroban/abacus-react` package has independent versioning and automated npm publishing. Use scoped commits to trigger package releases:
+
+#### NPM Package Release Triggers
+
+```bash
+# Minor version bump for new features
+feat(abacus-react): add new bead animation system
+
+# Patch version bump for bug fixes
+fix(abacus-react): resolve gesture detection issue
+
+# Patch version bump for performance improvements
+perf(abacus-react): optimize bead rendering performance
+
+# Major version bump for breaking changes
+feat(abacus-react)!: change callback signature
+# or
+feat(abacus-react): redesign API
+
+BREAKING CHANGE: callback functions now receive different parameters
+```
+
+#### Package Release Workflow
+
+1. **Automatic**: Any commit to `main` branch with `(abacus-react)` scope triggers publishing
+2. **Dual publishing**: Package is published to both npm and GitHub Packages simultaneously
+3. **Manual testing**: From `packages/abacus-react/`, run `pnpm release:dry-run`
+4. **Version tags**: Package releases are tagged as `abacus-react-v1.2.3` (separate from monorepo versions)
+5. **Authentication**: Requires `NPM_TOKEN` secret for npm and uses `GITHUB_TOKEN` for GitHub Packages
+
+#### Important Notes
+
+- **Package scope required**: Use `feat(abacus-react):` not just `feat:` for package releases
+- **Independent versioning**: Package versions are separate from monorepo versions
+- **Path filtering**: Only changes in `packages/abacus-react/` directory trigger builds
+- **Test requirements**: Package tests must pass before publishing

 ## Development

+### 📦 NPM Package Publishing
+
+The `@soroban/abacus-react` package is automatically published to **both npm and GitHub Packages** using semantic versioning. To trigger a release:
+
+```bash
+# For new features (minor version bump)
+git commit -m "feat(abacus-react): add new bead animation system"
+
+# For bug fixes (patch version bump)
+git commit -m "fix(abacus-react): resolve gesture detection issue"
+
+# For breaking changes (major version bump)
+git commit -m "feat(abacus-react)!: change callback signature"
+```
+
+**Important**: Use the `(abacus-react)` scope in commit messages to trigger package releases. Regular commits without this scope only affect the monorepo versioning.
+
+📖 **Full details**: See [CONTRIBUTING.md](./CONTRIBUTING.md#package-specific-publishing) for complete workflow documentation.

-## Advanced Customization
+## Advanced Features

-### Granular Styling
+### Place-Value Based Targeting
+
+Target beads by mathematical place value instead of visual column position:
+
+```tsx
+// Target beads by place value (recommended)
+const placeValueHighlights = [
+  { placeValue: 0, beadType: 'earth', position: 2 },  // Ones place, 3rd earth bead
+  { placeValue: 1, beadType: 'heaven' },              // Tens place, heaven bead
+  { placeValue: 2, beadType: 'earth', position: 0 }   // Hundreds place, 1st earth bead
+];
+
+// Legacy column-index targeting (still supported)
+const columnHighlights = [
+  { columnIndex: 2, beadType: 'earth', position: 2 }, // Rightmost column
+  { columnIndex: 1, beadType: 'heaven' },             // Middle column
+  { columnIndex: 0, beadType: 'earth', position: 0 }  // Leftmost column
+];
+
+<AbacusReact highlightBeads={placeValueHighlights} />
+```
+
+### Progressive Tutorial Steps
+
+Create multi-step interactive tutorials:
+
+```tsx
+const tutorialSteps = [
+  {
+    placeValue: 0,
+    beadType: 'earth',
+    position: 0,
+    stepIndex: 0,
+    direction: 'activate',
+    order: 1
+  },

+
+### Commit Message Format
+
+Use these prefixes for commits that affect the `packages/abacus-react` directory:
+
+```bash
+# New features (minor version bump)
+feat(abacus-react): add gesture recognition system
+
+# Bug fixes (patch version bump)
+fix(abacus-react): resolve animation timing issues
+
+# Performance improvements (patch version bump)
+perf(abacus-react): optimize bead rendering performance
+
+# Breaking changes (major version bump)
+feat(abacus-react)!: redesign callback API
+# or
+feat(abacus-react): change component interface
+
+BREAKING CHANGE: callback functions now receive different parameters
+```
+
+### Release Process
+
+1. **Automatic**: Releases happen automatically when changes are pushed to `main` branch
+2. **Dual publishing**: Package is published to both npm and GitHub Packages simultaneously
+3. **Manual testing**: Run `pnpm release:dry-run` to test release without publishing
+4. **Version tags**: Releases are tagged as `abacus-react-v1.2.3` (separate from monorepo versions)
+
+### Development Commands
+
+```bash
+# Build the package
+pnpm build
+
+# Run tests
+pnpm test:run
+
+# Run Storybook locally
+pnpm storybook
+
+# Test release process (dry run)
+pnpm release:dry-run
+```
