+title: Project Architecture Sniffer
+last_updated: Jan 7, 2024
+---
+
+The [Project Architecture Sniffer](https://github.com/spryker/project-architecture-sniffer) is a powerful tool designed specifically for Spryker projects, leveraging the capabilities of the [PHP Mess Detector](https://phpmd.org) to maintain and enforce architectural standards.
+
+The tool includes:
+
+* Adapted PHPMD rules tailored to the needs of Spryker projects.
+* [Architecture Sniffer](https://github.com/spryker/architecture-sniffer) rules for enforcing core-specific conventions.
+* Newly designed rules created specifically to address challenges unique to Spryker projects.
+
+We recommend using this tool to ensure that your project's architecture aligns with Spryker's best practices and guidelines.
+
+## Priority Levels
+- `1`: Сritical
+- `2`: Major
+- `3`: Medium
+
+We recommend minimum priority `3` by default for local and CI checks.
+
+## Usage
+
+Make sure you include the sniffer as `require-dev` dependency:
+```
+composer require --dev spryker/project-architecture-sniffer
+```
+
+### Running
+
+Find [command line option](https://phpmd.org/documentation/index.html).
+
+You can run the Project Architecture Sniffer from CLI by using:
+```
+vendor/bin/phpmd src/Pyz/ text vendor/spryker/project-architecture-sniffer/src/ruleset.xml --minimumpriority 3
+```
+
+### Baseline
+
+Existing projects and demo-shops may contain rule violations.
+The decision to refactor existing violations may be at the discretion of each project individually.
+It is recommended to approach this in a differentiated manner.
+To integrate rules into the project immediately, there recommended to generate a [baseline](https://phpmd.org/documentation/#baseline) and move forward.
+It is also permissible to [suppress rules](https://phpmd.org/documentation/suppress-warnings.html) on a case-by-case basis.
+
+{% info_block infoBox %}
+
+Spryker demo shops may contain violations when analyzed with the Architecture Sniffer, as the tool includes more specific rules by default. 
+It is recommended to generate a baseline during the initialization phase of your project development. 
+This allows you to focus on addressing violations related to project-level integrations.
