RulePaste

Backend

Laravel rules file

A Laravel app on Composer and Pest. Controllers stay thin, validation is a form request, and env() is not called from a controller. The frontend stack you already have stays put.

Change this stack in the generator

The files

Same rules, wrapped for each tool. Use the file your editor lists. Legacy files are there for older builds.

---description: "Project rules for PHP, Laravel, Pest, Composer. Generated by RulePaste."alwaysApply: true--- # Project rules Stack: PHP, Laravel, Pest, Composer. Follow these rules on every task. If a rule disagrees with existing code, match the code and mention the difference. If a rule disagrees with a direct user instruction, follow the user. ## Working agreement - Read the files you will change before editing them. Do not invent the project layout from memory.- Change only what the task needs. No drive-by refactors, renames, or formatting of untouched lines.- Match the patterns already in the repo over a generic style guide.- Do not add dependencies, config files, or abstractions the task did not ask for.- Do not commit secrets, and do not paste `.env` values, tokens, or private keys into code or chat.- If a requirement is ambiguous, choose the smallest reading, state that assumption, and continue. ## Commands - Install PHP dependencies with `composer install`. Commit `composer.lock`.- Composer is the package manager. A package.json, if present, is only for frontend assets.- Prefer `composer run dev` when that script exists. Otherwise use `php artisan serve` for a local API.- Tests: `php artisan test`. Format changed PHP with `vendor/bin/pint` when Pint is installed.- Do not run `migrate` against a shared database unless the user asked for that. ## PHP - Match the PHP version in `composer.json`. Type new properties, parameters, and return values.- Keep `declare(strict_types=1);` if the file has it, and add it to new files when the package uses it.- PSR-12 formatting. Autoload through Composer. Do not `require` class files by path.- Do not hide errors with `@`. Queries use the query builder or bound parameters, never interpolated request data. ## Laravel - Follow the routing style this repo uses (`routes/*.php` or `bootstrap/app.php`). Do not invent a third style.- Controllers stay thin. Validate with a Form Request, not a long controller method.- Define Eloquent relationships on the model and eager-load with `with()` when a loop touches a relation.- Migrations are append-only. Create a new one with Artisan. Do not edit a migration that has run in production.- Call `config()` in application code. Call `env()` only inside config files.- Stay on the frontend already installed (Blade, Inertia, or Livewire). Use the auth starter already installed. Do not add a second one.- Put slow work on the queue if the project has one. Format changed PHP with Pint when `vendor/bin/pint` exists. ## Pest - Write `it()` or `test()` closures. Feature tests belong in `tests/Feature` and hit HTTP. Unit tests do not boot the whole framework for a pure class.- Create records with factories. Do not depend on rows that happen to exist locally.- Run `php artisan test`. Do not add PHPUnit classes beside Pest for the same area. ## Composer - Install PHP dependencies with `composer install`. Add packages with `composer require`. Commit `composer.lock`.- Do not load classes by hand. Autoload through Composer. ## Testing expectations - When you fix a bug, add a test that fails before the fix and passes after, in the repo's current test style.- When you change behavior a caller can observe, update or add a test for that behavior.- Do not test private helpers, framework internals, or third-party libraries. ## Code style - Keep strict type and lint settings on. Do not weaken them to get a green build.- No new `any`, and no empty catch blocks. Prefer `unknown` and narrowing. Handle every fallible call.- Give exported functions an explicit type when the inferred type is not obvious.- Follow the repo formatter. Do not hand-format files the formatter owns.- Do not add comments that restate the code.- Comment only a constraint, invariant, or tradeoff the code itself cannot show.- No file-header banners and no changelog comments. ## Safety - Never commit `.env`, keystores, or credential files. When a new variable is required, add an empty placeholder to the example env file.- Do not disable authentication, authorization, or TLS checks to make a test pass.- Do not force-push, `reset --hard`, drop a database, or delete a directory tree unless the user asked for that exact action.- Do not edit vendored or generated output (`node_modules`, `dist`, `.next`, `vendor`, `Library`, `.godot`). Change the source and regenerate. ## Done when - The change does what was asked and nothing extra.- New or changed behavior is covered at the level in Testing expectations.- The commands in this file that apply to the touched files have been run, or you say which command you could not run.- The diff has no unrelated files, lockfile churn, or secrets. 

Install

  1. Create `.cursor/rules/` in the project root if it does not exist.
  2. Save this file as `.cursor/rules/project.mdc`. The `.mdc` extension and the frontmatter are required. A plain `.md` file in that folder is ignored.
  3. Commit it. Open a new Cursor chat. Check Settings, Rules, and confirm the rule is listed as Always Apply.
  4. Keep a single rule under a few hundred lines. Split later files by topic and set `alwaysApply: false` plus `globs` when a rule is only for some files.

Install

  1. Save as `.cursorrules` in the project root only if you are on an older Cursor build that still lists this file.
  2. Current Cursor uses `.cursor/rules/*.mdc`. If you keep both, they will drift unless you regenerate them together.

Install

  1. Save as `CLAUDE.md` in the project root. `.claude/CLAUDE.md` also works if you want the root left clear.
  2. Commit it. Start a new Claude Code session. The file loads at session start, not in the middle of an old one.
  3. When the file gets long, move a topic into `.claude/rules/<topic>.md`. Add a `paths` list only if that topic should load for certain files.

Install

  1. Create `.devin/rules/` and save this file as `.devin/rules/project.md`. Devin Desktop (formerly Windsurf) prefers this path. `.windsurf/rules/` still works as a fallback.
  2. `trigger: always_on` loads it in every chat. Keep the file under 12,000 characters or it can be truncated with no error.
  3. Commit it and start a new chat. If you also keep `.windsurfrules`, make sure the two files do not disagree.

Install

  1. Create `.github/` if needed and save this file as `.github/copilot-instructions.md`.
  2. Commit it. Copilot picks up repository instructions for Chat and, on supported plans, code review and the cloud agent.
  3. For rules that should only affect some files, add `.github/instructions/<name>.instructions.md` with `applyTo` frontmatter instead of growing this file.

Do not hand-format files the formatter owns.- Do not add comments that restate the code.- Comment only a constraint, invariant, or tradeoff the code itself cannot show.- No file-header banners and no changelog comments. ## Safety - Never commit `.env`, keystores, or credential files. When a new variable is required, add an empty placeholder to the example env file.- Do not disable authentication, authorization, or TLS checks to make a test pass.- Do not force-push, `reset --hard`, drop a database, or delete a directory tree unless the user asked for that exact action.- Do not edit vendored or generated output (`node_modules`, `dist`, `.next`, `vendor`, `Library`, `.godot`). Change the source and regenerate. ## Done when - The change does what was asked and nothing extra.- New or changed behavior is covered at the level in Testing expectations.- The commands in this file that apply to the touched files have been run, or you say which command you could not run.- The diff has no unrelated files, lockfile churn, or secrets. 

Install

  1. Save as `AGENTS.md` in the project root. Codex, Cursor, Copilot CLI, Devin, and many other agents look for this name.
  2. The file is plain Markdown. Do not add frontmatter.
  3. In a monorepo, add a nested AGENTS.md next to a service that needs different commands. Do not leave an empty `AGENTS.override.md` beside it. Codex treats that empty file as the instructions for the folder.
  4. Commit it and start a new agent session.

What each section does

Working agreement

The habits that keep an agent from rewriting the repo while it solves a small task.

Commands

The install, dev, test, and lint commands for this stack, so the agent runs the project's tools instead of guessing.

PHP

Typed signatures and prepared queries for new PHP.

Laravel

Keeps validation in form requests and environment reads inside config files.

Pest

Feature and unit tests in the Pest style Laravel ships with.

Composer

Composer is the PHP package manager. The lockfile stays committed.

Testing expectations

How much test coverage this project wants from the agent, separate from which test runner is installed.

Code style

How strict the types, lint, and comments should be. This is the knob most people actually want to change.

Safety

Hard stops: secrets, destructive git commands, and generated folders.

Done when

The checklist the agent should satisfy before it calls the task finished.

Questions

Does this force Inertia or Livewire?

No. It tells the agent to stay on Blade, Inertia, or Livewire, whichever the repo already uses.

Where should a new validation rule live?

In a Form Request created for that action, not inline in a long controller method.
