+### Avoid circular dependencies
+
+As part of a future effort to use correct and idempotent build tools we need our code to be
+able to be represented as a directed acyclic graph. We must avoid having circular dependencies 
+both on code and type imports to achieve that. One of the most critical parts is the plugins 
+code. We've developed a tool to identify plugins with circular dependencies which 
+has allowed us to build a list of plugins who have circular dependencies 
+between each other. 
+
+When building plugins we should avoid importing from plugins 
+who are known to have circular dependencies at the moment as well as introducing 
+new circular dependencies. You can run the same tool we use on our CI locally by 
+typing `node scripts/find_plugins_with_circular_deps --debug`. It will error out in 
+case new circular dependencies has been added with your changes 
+(which will also happen in the CI) as well as print out the current list of
+the known circular dependencies which, as mentioned before, should not be imported 
+by your code until the circular dependencies on these have been solved. 
+
 ## SASS files
 
 When writing a new component, create a sibling SASS file of the same name and import directly into the **top** of the JS/TS component file. Doing so ensures the styles are never separated or lost on import and allows for better modularization (smaller individual plugin asset footprint).

 - A project must emit its type declaration. It's not always possible to generate a type declaration if the compiler cannot infer a type. There are two basic cases:
 
 1. Your plugin exports a type inferring an internal type declared in Kibana codebase. In this case, you'll have to either export an internal type or to declare an exported type explicitly.
@@ -30,6 +30,8 @@ This architecture imposes several limitations to which we must comply:
 Since project refs rely on generated `d.ts` files, the migration order does matter. You can migrate your plugin only when all the plugin dependencies already have migrated. It creates a situation where commonly used plugins (such as `data` or `kibana_react`) have to migrate first.
 Run `node scripts/find_plugins_without_ts_refs.js --id your_plugin_id` to get a list of plugins that should be switched to TS project refs to unblock your plugin migration.
 
+Additionally, in order to migrate into project refs, you also need to make sure your plugin doesn't have circular dependencies with other plugins both on code and type imports. We run a job in the CI for each PR trying to find if new circular dependencies are being added which runs our tool with `node scripts/find_plugins_with_circular_deps`. However there are also a couple of circular dependencies already identified and that are in an allowed list to be solved. You also need to make sure your plugin don't rely in any other plugin into that allowed list. For a complete overview of the circular dependencies both found and in the allowed list as well as the complete circular dependencies path please run the following script locally with the debug flag `node scripts/find_plugins_with_circular_deps --debug` .
