+# GitHub Copilot instructions for plugins-sdk-php
+
+This guidance file helps Copilot generate code aligned with project standards and domain design for the Staffbase Plugin SDK for PHP.
+
+## General Copilot goals
+- Follow project coding style and PSR-4 namespace conventions.
+- Prefer using and extending the existing src/SSOToken, PluginSession, and RemoteCall infrastructure.
+- When creating new code, integrate with provided interfaces, traits, and classes (see src/SSOData, src/RemoteCall, src/Exceptions).
+- All code should work with PHP 8.3, strict_types, and Composer autoloading.
+- When suggesting test code, match the structure of test/ files and use PHPUnit 10+ only.
+
+## Style and static analysis
+- Conform to rules in .php-cs-fixer.dist.php (array_syntax short, strict_types, remove unused imports, use strict parameters).
+- Code should pass `composer run cs-fixer:check` and `composer run lint` on commit.
+- Code should pass PHPStan at level 4 (phpstan.neon.dist), including for new types, traits, and test cases.
+
+## Domain guidance
+- For SSO authentication, use and extend SSOToken, PluginSession, and SSODataTrait as the foundation — avoid duplicating token logic.
+- Remote call support should use AbstractRemoteCallHandler or interfaces from src/RemoteCall if you need plugin event handling (e.g., deletion).
+- When handling sessions, use PluginSession and its methods for SSO data. Avoid manual $_SESSION logic except for advanced cases.
+- Exceptions should inherit src/Exceptions base classes as relevant.
+
+## Recommended code generation practices
+- Prefer composition and interface-driven design (see src/SSOData, src/RemoteCall, src/Exceptions).
+- Follow README.md example patterns for token creation, session management, and error handling.
+- Place new classes in src/ with Staffbase\plugins\sdk\ namespace; place tests in test/ with Staffbase\plugins\test\ namespace.
+
+## Copilot DON'Ts
+- Do not add new dependencies unless absolutely required and justified in code comments.
+- Do not use deprecated PHP practices or legacy global state.
+- Do not bypass static analysis rules for quick fixes.
+- Do not create code outside of src/ and test/ unless explicitly requested. Never create example or playground code that is not integrated into the SDK or its tests.
+
+## Documentation
+- Consult CLAUDE.md at project root for further architectural guidance and standard commands.
+- Reference README.md and inline docblocks for API documentation style.

+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+
+## Quick commands
+
+- Install dependencies: composer install
+- Run unit tests: composer test (runs phpunit)
+- Run tests with coverage: composer run test:coverage
+- Run static analysis: composer run phpstan (phpstan analyse --memory-limit=1G)
+- Run code style checks: composer run cs-fixer:check
+- Auto-fix code style: composer run cs-fixer:fix
+- Full check: composer run check (runs cs-fixer check, phpstan, and test coverage)
+- Lint (style + static analysis): composer run lint
+
+To run a single PHPUnit test (by file):
+- ./vendor/bin/phpunit path/to/TestFile.php
+
+To run a single test method:
+- ./vendor/bin/phpunit --filter testMethodName path/to/TestFile.php
+
+
+## Project overview — high level
+
+This repository provides a small PHP SDK for Staffbase plugin Single Sign-On (SSO) token parsing and validation.
+
+High-level structure:
+
+- src/: Core library code. Primary classes:
+  - src/SSOToken.php — main JWT parsing & validation wrapper for plugin SSO tokens (uses lcobucci/jwt)
+  - src/SSOTokenGenerator.php — utility to generate test tokens for unit tests
+  - src/PluginSession.php — session wrapper for persisting SSO data between requests
+  - src/RemoteCall/* — handlers and interfaces for app-initiated remote calls (delete-instance, etc.)
+  - src/SSOData/* — data interfaces/traits for shared and SSO specific claims
+  - src/Exceptions/* — domain exceptions (SSOAuthenticationException, SSOException, ...)
+  - src/Validation/* — custom validation constraints used by php-jwt/token validation
+  - src/AbstractToken.php — base token parsing/verification logic used by SSOToken and others
+
+- test/: PHPUnit test suite for the library. Tests instantiate SSOToken, SSOTokenGenerator and validate behavior.
+
+- composer.json: Composer metadata and scripts (lint, phpstan, tests, cs-fixer). Key runtime deps: lcobucci/jwt, lcobucci/clock.
+
+- phpstan.neon.dist: phpstan configuration (analyse src and test at level 4 by default).
+
+- README.md: user-facing documentation and examples (installation, usage examples, remote calls).
+
+
+## CI and hooks
+
+- GitHub Actions: a workflow badge exists in README, check .github/workflows for exact CI steps if needed.
+- Composer hooks: composer.json registers post-install and post-update hooks for composer-git-hooks. Pre-commit hooks in composer.extra.hooks run "composer fix" and "composer phpstan".
+
+
+## Notes for future Claude Code instances
+
+- Use Composer scripts defined in composer.json for all common operations (tests, lint, phpstan, cs-fixer). Prefer the scripts so local project configuration is respected.
+- When adding or editing PHP code, run CS Fixer and PHPStan locally (composer run fix; composer run phpstan) before running tests.
+- Tests are run with phpunit (vendor/bin/phpunit). For debugging a single test, prefer running vendor/bin/phpunit --filter.
+
+Key files to inspect for behavior changes:
+- src/SSOToken.php: constructor, token parsing and validation flow
+- src/AbstractToken.php: core token parsing/verification logic
+- src/Validation/HasInstanceId.php: custom constraint used by SSOToken
+- README.md and doc/api.md: user-visible behavior and API
+
+
+## When editing code
+
+- Prefer editing existing files rather than creating new ones unless a new module is required.
+- Follow PSR-4 autoloading in composer.json (namespace Staffbase\plugins\sdk\ -> src/)
+- Keep phpstan.neon.dist level consideration in mind
