Skills Activation

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

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.

Laravel Boost

Tools

• Laravel Boost is an MCP server with tools designed specifically for this application. Prefer Boost tools over manual alternatives like shell commands or file reads.
• Use database-query to run read-only queries against the database instead of writing raw SQL in tinker.
• Use database-schema to inspect table structure before writing migrations or models.
• Use get-absolute-url to resolve the correct scheme, domain, and port for project URLs. Always use this before sharing a URL with the user.
• Use browser-logs to read browser logs, errors, and exceptions. Only recent logs are useful, ignore old entries.

Searching Documentation (IMPORTANT)

• Always use search-docs before making code changes. Do not skip this step. It returns version-specific docs based on installed packages automatically.
• Pass a packages array to scope results when you know which packages are relevant.
• Use multiple broad, topic-based queries: ['rate limiting', 'routing rate limiting', 'routing']. Expect the most relevant results first.
• Do not add package names to queries because package info is already shared. Use test resource table, not filament 4 test resource table.

Search Syntax

1. Use words for auto-stemmed AND logic: rate limit matches both "rate" AND "limit".
2. Use "quoted phrases" for exact position matching: "infinite scroll" requires adjacent words in order.
3. Combine words and phrases for mixed queries: middleware "rate limit".
4. Use multiple queries for OR logic: queries=["authentication", "middleware"].

Artisan

• Run Artisan commands directly via the command line (e.g., php artisan route:list). Use php artisan list to discover available commands and php artisan [command] --help to check parameters.
• Inspect routes with php artisan route:list. Filter with: --method=GET, --name=users, --path=api, --except-vendor, --only-vendor.
• Read configuration values using dot notation: php artisan config:show app.name, php artisan config:show database.default. Or read config files directly from the config/ directory.

Tinker

• Execute PHP in app context for debugging and testing code. Do not create models without user approval, prefer tests with factories instead. Prefer existing Artisan commands over custom tinker code.
• Always use single quotes to prevent shell expansion: php artisan tinker --execute 'Your::code();'
  • Double quotes for PHP strings inside: php artisan tinker --execute 'User::where("active", true)->count();'

=== php rules ===

PHP

• Always use curly braces for control structures, even for single-line bodies.
• Use PHP 8 constructor property promotion: public function __construct(public GitHub $github) { }. Do not leave empty zero-parameter __construct() methods unless the constructor is private.
• Use explicit return type declarations and type hints for all method parameters: function isAccessible(User $user, ?string $path = null): bool
• Follow existing application Enum naming conventions.
• Prefer PHPDoc blocks over inline comments. Only add inline comments for exceptionally complex logic.
• Use array shape type definitions in PHPDoc blocks.

=== deployments rules ===

Deployment

• Laravel can be deployed using Laravel Cloud, which is the fastest way to deploy and scale production Laravel applications.

=== 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 v3

• Use all Inertia features from v1, v2, and v3. Check the documentation before making changes to ensure the correct approach.
• New v3 features: standalone HTTP requests (useHttp hook), optimistic updates with automatic rollback, layout props (useLayoutProps hook), instant visits, simplified SSR via @inertiajs/vite plugin, custom exception handling for error pages.
• Carried over from v2: 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.
• Axios has been removed. Use the built-in XHR client with interceptors, or install Axios separately if needed.
• Inertia::lazy() / LazyProp has been removed. Use Inertia::optional() instead.
• Prop types (Inertia::optional(), Inertia::defer(), Inertia::merge()) work inside nested arrays with dot-notation paths.
• SSR works automatically in Vite dev mode with @inertiajs/vite - no separate Node.js server needed during development.
• Event renames: invalid is now httpException, exception is now networkError.
• router.cancel() replaced by router.cancelAll().
• The future configuration namespace has been removed - all v2 future options are now always enabled.

=== 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.

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.

URL Generation

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

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

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

=== 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}.
• The {name} argument should not include the test suite directory. Use php artisan make:test --pest SomeFeatureTest instead of php artisan make:test --pest Feature/SomeFeatureTest.
• 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.

Behavioral guidelines to reduce common LLM coding mistakes. Merge with project-specific instructions as needed.

Tradeoff: These guidelines bias toward caution over speed. For trivial tasks, use judgment.

1. Think Before Coding

Don't assume. Don't hide confusion. Surface tradeoffs.

Before implementing:

• State your assumptions explicitly. If uncertain, ask.
• If multiple interpretations exist, present them - don't pick silently.
• If a simpler approach exists, say so. Push back when warranted.
• If something is unclear, stop. Name what's confusing. Ask.

2. Simplicity First

Minimum code that solves the problem. Nothing speculative.

• No features beyond what was asked.
• No abstractions for single-use code.
• No "flexibility" or "configurability" that wasn't requested.
• No error handling for impossible scenarios.
• If you write 200 lines and it could be 50, rewrite it.

Ask yourself: "Would a senior engineer say this is overcomplicated?" If yes, simplify.

3. Surgical Changes

Touch only what you must. Clean up only your own mess.

When editing existing code:

• Don't "improve" adjacent code, comments, or formatting.
• Don't refactor things that aren't broken.
• Match existing style, even if you'd do it differently.
• If you notice unrelated dead code, mention it - don't delete it.

When your changes create orphans:

• Remove imports/variables/functions that YOUR changes made unused.
• Don't remove pre-existing dead code unless asked.

The test: Every changed line should trace directly to the user's request.

4. Goal-Driven Execution

Define success criteria. Loop until verified.

Transform tasks into verifiable goals:

• "Add validation" → "Write tests for invalid inputs, then make them pass"
• "Fix the bug" → "Write a test that reproduces it, then make it pass"
• "Refactor X" → "Ensure tests pass before and after"

For multi-step tasks, state a brief plan:

1. [Step] → verify: [check]
2. [Step] → verify: [check]
3. [Step] → verify: [check]

Strong success criteria let you loop independently. Weak criteria ("make it work") require constant clarification.

These guidelines are working if: fewer unnecessary changes in diffs, fewer rewrites due to overcomplication, and clarifying questions come before implementation rather than after mistakes.
