This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

Whisper Money is a privacy-first personal finance app. Your data is never shared with third parties—you are the owner. It uses Laravel 12 (PHP 8.4) backend with React 19 frontend via Inertia.js v2.

Commands

Development

composer run dev          # Start full dev environment (PHP server, queue, Vite, logs)
bun run dev               # Vite dev server only

Build & Quality

bun run build             # Production build (don't run automatically - ask user)
bun run format            # Format code with Prettier
bun run lint              # ESLint with auto-fix
vendor/bin/pint --dirty   # PHP code formatting

Testing

php artisan test --exclue-testsuite=Browser     # Run all tests
php artisan test tests/Feature/ExampleTest.php  # Run specific file
php artisan test --filter=testName              # Filter by test name

CI Requirements (must pass before finalizing changes)

bun install --frozen-lockfile
composer install --no-interaction --prefer-dist --optimize-autoloader
bun run build
./vendor/bin/pest
vendor/bin/pint --test
bun run format
bun run lint

Architecture

Backend (Laravel 12)

• Streamlined structure: No middleware files in app/Http/Middleware/, configuration in bootstrap/app.php
• Commands auto-register: Files in app/Console/Commands/ are automatically available
• Form Requests: Always use for validation instead of inline controller validation
• Eloquent: Prefer Model::query() over DB::, use eager loading to prevent N+1

Frontend (React 19 + Inertia v2)

• Pages: resources/js/pages/ - Inertia page components
• Components: resources/js/components/ - Reusable UI components
• Services: resources/js/services/ - Sync services with IndexedDB (Dexie) for offline support
• Wayfinder: Type-safe routes generated in resources/js/routes/ and resources/js/actions/

Wayfinder Usage

// Import controller methods (tree-shakable)
import { show, store } from '@/actions/App/Http/Controllers/PostController'

show(1)           // { url: "/posts/1", method: "get" }
show.url(1)       // "/posts/1"

// With Inertia Form component
<Form {...store.form()}><input name="title" /></Form>

Navigation

• Use router.visit() from @inertiajs/react or <Link> component
• Never use traditional <a> tags for internal navigation

Key Conventions

• PHP: Use constructor property promotion, explicit return types, curly braces for all control structures
• TypeScript: Strict mode enabled, use proper type annotations
• Tailwind v4: CSS-first configuration with @theme directive, use gap utilities instead of margins for spacing
• Dark mode: All new components must support dark mode using dark: variants
• Tests: Write Pest tests for all changes, use factories for model creation

Database

• Eloquent relationships with return type hints
• User model uses UUID primary keys
• Privacy-focused: no data shared with third parties

Skills Activation

This project has domain-specific skills available. You MUST activate the relevant skill whenever you work in that domain—don't wait until you're stuck.

• cashier-stripe-development — Handles Laravel Cashier Stripe integration including subscriptions, webhooks, Stripe Checkout, invoices, charges, refunds, trials, coupons, metered billing, and payment failure handling. Triggered when a user mentions Cashier, Billable, IncompletePayment, stripe_id, newSubscription, Stripe subscriptions, or billing. Also applies when setting up webhooks, handling SCA/3DS payment failures, testing with Stripe test cards, or troubleshooting incomplete subscriptions, CSRF webhook errors, or migration publish issues.
• pennant-development — Use when working with Laravel Pennant the official Laravel feature flag package. Trigger whenever the query mentions Pennant by name or involves feature flags or feature toggles in a Laravel project. Tasks include defining feature flags checking whether features are active creating class based features in app/Features using Blade @feature directives scoping flags to users or teams building custom Pennant storage drivers protecting routes with feature flags testing feature flags with Pest or PHPUnit and implementing A B testing or gradual rollouts with feature flags. Do not trigger for generic Laravel configuration authorization policies authentication or non Pennant feature management systems.
• wayfinder-development — Activates whenever referencing backend routes in frontend components. Use when importing from @/actions or @/routes, calling Laravel routes from TypeScript, or working with Wayfinder route functions.
• pest-testing — Use this skill for Pest PHP testing in Laravel projects only. Trigger whenever any test is being written, edited, fixed, or refactored — including fixing tests that broke after a code change, adding assertions, converting PHPUnit to Pest, adding datasets, and TDD workflows. Always activate when the user asks how to write something in Pest, mentions test files or directories (tests/Feature, tests/Unit, tests/Browser), or needs browser testing, smoke testing multiple pages for JS errors, or architecture tests. Covers: it()/expect() syntax, datasets, mocking, browser testing (visit/click/fill), smoke testing, arch(), Livewire component tests, RefreshDatabase, and all Pest 4 features. Do not use for factories, seeders, migrations, controllers, models, or non-test PHP code.
• inertia-react-development — Develops Inertia.js v2 React client-side applications. Activates when creating React pages, forms, or navigation; using , , useForm, or router; working with deferred props, prefetching, or polling; or when user mentions React with Inertia, React pages, React forms, or React navigation.
• tailwindcss-development — Always invoke when the user's message includes 'tailwind' in any form. Also invoke for: building responsive grid layouts (multi-column card grids, product grids), flex/grid page structures (dashboards with sidebars, fixed topbars, mobile-toggle navs), styling UI components (cards, tables, navbars, pricing sections, forms, inputs, badges), adding dark mode variants, fixing spacing or typography, and Tailwind v3/v4 work. The core use case: writing or fixing Tailwind utility classes in HTML templates (Blade, JSX, Vue). Skip for backend PHP logic, database queries, API routes, JavaScript with no HTML/CSS component, CSS file audits, build tool configuration, and vanilla CSS.
• fortify-development — Laravel Fortify headless authentication backend development. Activate when implementing authentication features including login, registration, password reset, email verification, two-factor authentication (2FA/TOTP), profile updates, headless auth, authentication scaffolding, or auth guards in Laravel applications.

Conventions

• You must follow all existing code conventions used in this application. When creating or editing a file, check sibling files for the correct structure, approach, and naming.
• Use descriptive names for variables and methods. For example, isRegisteredForDiscounts, not discount().
• Check for existing components to reuse before writing a new one.

Verification Scripts

• Do not create verification scripts or tinker when tests cover that functionality and prove they work. Unit and feature tests are more important.

Application Structure & Architecture

• Stick to existing directory structure; don't create new base folders without approval.
• Do not change the application's dependencies without approval.

Frontend Bundling

• If the user doesn't see a frontend change reflected in the UI, it could mean they need to run npm run build, npm run dev, or composer run dev. Ask them.

Documentation Files

• You must only create documentation files if explicitly requested by the user.

Replies

• Be concise in your explanations - focus on what's important rather than explaining obvious details.

=== boost rules ===

Laravel Boost

• Laravel Boost is an MCP server that comes with powerful tools designed specifically for this application. Use them.

Artisan Commands

• Run Artisan commands directly via the command line (e.g., php artisan route:list, php artisan tinker --execute "...").
• Use php artisan list to discover available commands and php artisan [command] --help to check parameters.

URLs

• Whenever you share a project URL with the user, you should use the get-absolute-url tool to ensure you're using the correct scheme, domain/IP, and port.

Debugging

• Use the database-query tool when you only need to read from the database.
• Use the database-schema tool to inspect table structure before writing migrations or models.
• To execute PHP code for debugging, run php artisan tinker --execute "your code here" directly.
• To read configuration values, read the config files directly or run php artisan config:show [key].
• To inspect routes, run php artisan route:list directly.
• To check environment variables, read the .env file directly.

Reading Browser Logs With the browser-logs Tool

• You can read browser logs, errors, and exceptions using the browser-logs tool from Boost.
• Only recent browser logs will be useful - ignore old logs.

Searching Documentation (Critically Important)

• Boost comes with a powerful search-docs tool you should use before trying other approaches when working with Laravel or Laravel ecosystem packages. This tool automatically passes a list of installed packages and their versions to the remote Boost API, so it returns only version-specific documentation for the user's circumstance. You should pass an array of packages to filter on if you know you need docs for particular packages.
• Search the documentation before making code changes to ensure we are taking the correct approach.
• Use multiple, broad, simple, topic-based queries at once. For example: ['rate limiting', 'routing rate limiting', 'routing']. The most relevant results will be returned first.
• Do not add package names to queries; package information is already shared. For example, use test resource table, not filament 4 test resource table.

Available Search Syntax

1. Simple Word Searches with auto-stemming - query=authentication - finds 'authenticate' and 'auth'.
2. Multiple Words (AND Logic) - query=rate limit - finds knowledge containing both "rate" AND "limit".
3. Quoted Phrases (Exact Position) - query="infinite scroll" - words must be adjacent and in that order.
4. Mixed Queries - query=middleware "rate limit" - "middleware" AND exact phrase "rate limit".
5. Multiple Queries - queries=["authentication", "middleware"] - ANY of these terms.

=== php rules ===

PHP

• Always use curly braces for control structures, even for single-line bodies.

Constructors

• Use PHP 8 constructor property promotion in __construct().
  • public function __construct(public GitHub $github) { }
• Do not allow empty __construct() methods with zero parameters unless the constructor is private.

Type Declarations

• Always use explicit return type declarations for methods and functions.
• Use appropriate PHP type hints for method parameters.

protected function isAccessible(User $user, ?string $path = null): bool
{
    ...
}

Enums

• Typically, keys in an Enum should be TitleCase. For example: FavoritePerson, BestLake, Monthly.

Comments

• Prefer PHPDoc blocks over inline comments. Never use comments within the code itself unless the logic is exceptionally complex.

PHPDoc Blocks

• Add useful array shape type definitions when appropriate.

=== tests rules ===

Test Enforcement

• Every change must be programmatically tested. Write a new test or update an existing test, then run the affected tests to make sure they pass.
• Run the minimum number of tests needed to ensure code quality and speed. Use php artisan test --compact with a specific filename or filter.

=== inertia-laravel/core rules ===

Inertia

• Inertia creates fully client-side rendered SPAs without modern SPA complexity, leveraging existing server-side patterns.
• Components live in resources/js/pages (unless specified in vite.config.js). Use Inertia::render() for server-side routing instead of Blade views.
• ALWAYS use search-docs tool for version-specific Inertia documentation and updated code examples.
• IMPORTANT: Activate inertia-react-development when working with Inertia client-side patterns.

Inertia v2

• Use all Inertia features from v1 and v2. Check the documentation before making changes to ensure the correct approach.
• New features: deferred props, infinite scroll, merging props, polling, prefetching, once props, flash data.
• When using deferred props, add an empty state with a pulsing or animated skeleton.

=== laravel/core rules ===

Do Things the Laravel Way

• Use php artisan make: commands to create new files (i.e. migrations, controllers, models, etc.). You can list available Artisan commands using php artisan list and check their parameters with php artisan [command] --help.
• If you're creating a generic PHP class, use php artisan make:class.
• Pass --no-interaction to all Artisan commands to ensure they work without user input. You should also pass the correct --options to ensure correct behavior.

Database

• Always use proper Eloquent relationship methods with return type hints. Prefer relationship methods over raw queries or manual joins.
• Use Eloquent models and relationships before suggesting raw database queries.
• Avoid DB::; prefer Model::query(). Generate code that leverages Laravel's ORM capabilities rather than bypassing them.
• Generate code that prevents N+1 query problems by using eager loading.
• Use Laravel's query builder for very complex database operations.

Model Creation

• When creating new models, create useful factories and seeders for them too. Ask the user if they need any other things, using php artisan make:model --help to check the available options.

APIs & Eloquent Resources

• For APIs, default to using Eloquent API Resources and API versioning unless existing API routes do not, then you should follow existing application convention.

Controllers & Validation

• Always create Form Request classes for validation rather than inline validation in controllers. Include both validation rules and custom error messages.
• Check sibling Form Requests to see if the application uses array or string based validation rules.

Authentication & Authorization

• Use Laravel's built-in authentication and authorization features (gates, policies, Sanctum, etc.).

URL Generation

• When generating links to other pages, prefer named routes and the route() function.

Queues

• Use queued jobs for time-consuming operations with the ShouldQueue interface.

Configuration

• Use environment variables only in configuration files - never use the env() function directly outside of config files. Always use config('app.name'), not env('APP_NAME').

Testing

• When creating models for tests, use the factories for the models. Check if the factory has custom states that can be used before manually setting up the model.
• Faker: Use methods such as $this->faker->word() or fake()->randomDigit(). Follow existing conventions whether to use $this->faker or fake().
• When creating tests, make use of php artisan make:test [options] {name} to create a feature test, and pass --unit to create a unit test. Most tests should be feature tests.

Vite Error

• If you receive an "Illuminate\Foundation\ViteException: Unable to locate file in Vite manifest" error, you can run npm run build or ask the user to run npm run dev or composer run dev.

=== wayfinder/core rules ===

Laravel Wayfinder

Wayfinder generates TypeScript functions for Laravel routes. Import from @/actions/ (controllers) or @/routes/ (named routes).

• IMPORTANT: Activate wayfinder-development skill whenever referencing backend routes in frontend components.
• Invokable Controllers: import StorePost from '@/actions/.../StorePostController'; StorePost().
• Parameter Binding: Detects route keys ({post:slug}) — show({ slug: "my-post" }).
• Query Merging: show(1, { mergeQuery: { page: 2, sort: null } }) merges with current URL, null removes params.
• Inertia: Use .form() with <Form> component or form.submit(store()) with useForm.

=== pint/core rules ===

Laravel Pint Code Formatter

• If you have modified any PHP files, you must run vendor/bin/pint --dirty --format agent before finalizing changes to ensure your code matches the project's expected style.
• Do not run vendor/bin/pint --test --format agent, simply run vendor/bin/pint --format agent to fix any formatting issues.

=== pest/core rules ===

Pest

• This project uses Pest for testing. Create tests: php artisan make:test --pest {name}.
• Run tests: php artisan test --compact or filter: php artisan test --compact --filter=testName.
• Do NOT delete tests without approval.

=== inertia-react/core rules ===

Inertia + React

• IMPORTANT: Activate inertia-react-development when working with Inertia React client-side patterns.

=== laravel/fortify rules ===

Laravel Fortify

• Fortify is a headless authentication backend that provides authentication routes and controllers for Laravel applications.
• IMPORTANT: Always use the search-docs tool for detailed Laravel Fortify patterns and documentation.
• IMPORTANT: Activate developing-with-fortify skill when working with Fortify authentication features.
