## Summary by CodeRabbit

- **New Features**
  - Enhanced project endpoints with dedicated support for creating and retrieving projects. Project creation now requires an associated team ID, and project listings feature improved pagination and sorting.
  - Expanded authorization controls to include project-related actions for standard users.

- **Refactor**
  - Redesigned project data structures for clearer representation of team and leader associations.
  - Streamlined validations and error handling for project operations.

- **Tests**
  - Introduced comprehensive tests to ensure robust functionality for project creation and retrieval.

<summary>src/main/kotlin/org/rucca/cheese/model/GetProjects200ResponseDataDTO.kt (1)</summary>

`12-12`: **Consistent renaming improves API structure.**

The renaming from `ProjectsGet200ResponseDataDTO` to `GetProjects200ResponseDataDTO` follows a more action-oriented naming convention, which aligns with the refactoring effort mentioned in the PR summary.

</details>
<details>
<summary>src/main/kotlin/org/rucca/cheese/model/CreateProject200ResponseDataDTO.kt (1)</summary>

`9-9`: **Improved naming convention enhances API clarity.**

The renaming from `ProjectsPost200ResponseDataDTO` to `CreateProject200ResponseDataDTO` is more descriptive of the action being performed and consistent with the other naming changes in the PR.

</details>
<details>
<summary>src/main/kotlin/org/rucca/cheese/user/UserService.kt (1)</summary>

`85-87`: **Good addition for consistent error handling.**

This utility method enhances validation by ensuring user existence before operations that require a valid user ID, providing a clean error message when a user isn't found. This matches the pattern mentioned in the AI summary for similar validation in TeamService.

</details>
<details>
<summary>src/main/kotlin/org/rucca/cheese/model/CreateProjectRequestExternalCollaboratorsInnerDTO.kt (1)</summary>

`8-8`: **Consistent naming improves code readability.**

The renaming from `ProjectsPostRequestExternalCollaboratorsInnerDTO` to `CreateProjectRequestExternalCollaboratorsInnerDTO` is part of the consistent pattern of improving naming throughout the codebase, making it clearer that this DTO is related to the project creation process.

</details>
<details>
<summary>src/main/kotlin/org/rucca/cheese/user/RolePermissionService.kt (1)</summary>

`172-177`: **Project permissions implementation looks good.**

The addition of project permissions for standard users is well-structured and follows the established pattern of other permission entries in the service. This enables users to create and enumerate projects, which aligns with the PR objective of implementing project functionality.

</details>
<details>
<summary>src/main/kotlin/org/rucca/cheese/project/ProjectEntity.kt (2)</summary>

`6-7`: **Good migration to cursor-based pagination.**

The import change supports the repository interface update to use cursor-based pagination, which is more efficient for large datasets than offset-based pagination.

---

`37-37`: <details>
<summary>✅ Verification successful</summary>

**Empty repository interface.**

While changing to `CursorPagingRepository` is good, consider adding custom query methods if needed for project-specific operations.


---

🏁 Script executed:

```shell
#!/bin/bash
# Check if any custom queries are defined elsewhere that might need to be moved here
rg -A 1 -B 1 "projectRepository\." --glob "!*ProjectRepository*"
```

Length of output: 1248

---



</details>

**Repository Interface: Minimal Implementation Accepted**

The current design extending `CursorPagingRepository` covers the necessary methods (as evidenced by its usage in `ProjectService` for operations such as `findById`, `save`, and `findAllWithIdCursor`). There's no evidence of custom query requirements elsewhere in the codebase. If, in the future, project-specific operations demand additional queries, consider expanding this interface accordingly.

<summary>src/main/kotlin/org/rucca/cheese/team/TeamService.kt (1)</summary>

`237-239`: **Good addition of team validation method.**

The `ensureTeamIdExists` method enhances error handling by providing a clear way to validate team existence before performing operations. This is more efficient than the existing `getTeam` method when you only need to check existence without retrieving the entire entity.

</details>
<details>
<summary>src/main/kotlin/org/rucca/cheese/model/ProjectDTO.kt (2)</summary>

`15-16`: **Documentation updated to match new properties.**

The documentation parameters have been correctly updated to reflect the new `team` and `leader` properties that replaced the previous `leaderId`.

---

`41-48`: <details>
<summary>❓ Verification inconclusive</summary>

**Good enhancement to ProjectDTO with full objects.**

Replacing `leaderId` with complete `team` and `leader` objects improves the API by providing more comprehensive data in a single response. The validation annotations are correctly applied, ensuring data integrity.

🏁 Script executed:

```shell
#!/bin/bash
# Check if the ProjectController properly handles these new DTO fields
rg -A 5 "ProjectDTO" --glob "*Controller.kt"
```

Length of output: 44

</details>

**Enhancement Verified – Manual Confirmation Needed for Controller Logic**

The updates in `ProjectDTO.kt` (i.e. replacing `leaderId` with full `team` and `leader` objects along with proper validation) look good. However, our automated search for references to these new fields in the controller files produced no output. To ensure that the `ProjectController` (and any relevant endpoints) correctly handles these DTO changes, please verify manually that:
  
- **ProjectController Usage:** The controller(s) correctly reference and process the updated `ProjectDTO` fields.
- **Mapping Adjustments:** Any logic formerly based on `leaderId` now properly handles the full `leader` object.
- **Data Integrity:** The API responses include the expected comprehensive details for both `team` and `leader`.

Once manual confirmation is done, we can be assured that the enhancement integrates seamlessly across the codebase.

</details>
<details>
<summary>src/main/kotlin/org/rucca/cheese/model/CreateProject200ResponseDTO.kt (2)</summary>

`13-13`: **Class name aligns well with updated naming convention.**  
Renaming the data class to `CreateProject200ResponseDTO` makes it clearer and more consistent with the overall project naming scheme.

---

`23-23`: <details>
<summary>❓ Verification inconclusive</summary>

**Ensure all references to `CreateProject200ResponseDataDTO` are updated.**  
Please verify that the old type `ProjectsPost200ResponseDataDTO` is no longer referenced anywhere in the codebase.

---

🏁 Script executed:

```shell
#!/bin/bash
# Check for references to the old type

</details>

**Manual Verification Required: Confirm Removal of Legacy Type Reference**

The grep command for `"ProjectsPost200ResponseDataDTO"` did not return any matches. However, since no output was produced—and this result is somewhat inconclusive—it’s best to manually verify that the old type is not referenced anywhere in the codebase. Please double-check that all instances have been updated to use the new type, `CreateProject200ResponseDataDTO`, including in files or test cases that might not be covered by the initial search.

- Verify across the repository that no files reference `"ProjectsPost200ResponseDataDTO"`.
- Double-check the implementation in **src/main/kotlin/org/rucca/cheese/model/CreateProject200ResponseDTO.kt** at line 23.
- Confirm that both production and test code have been updated accordingly.

`15-15`: **New parameter documented: `teamId`.**  
Including `@param teamId` in the docstring is good practice to keep the documentation up to date.

---

`23-23`: **Renaming class enhances readability.**  
Changing the data class name to `CreateProjectRequestDTO` better conveys its purpose for project creation requests.

---

`41-43`: **Validate `teamId` to avoid invalid input.**  
Since `teamId` is required, consider adding business logic or validation rules to ensure it isn’t zero or negative.  
[refactor_suggestion_good_to_have, verify]
Would you like a quick code snippet to implement this validation at the service or controller layer?

<details>
<summary>src/main/kotlin/org/rucca/cheese/api/ProjectsApi.kt (9)</summary>

`13-15`: **Imports updated for new DTOs.**  
The new imports (`CreateProject200ResponseDTO`, `CreateProjectRequestDTO`, `GetProjects200ResponseDTO`) match the updated model classes.

---

`33-34`: **Operation metadata updated for project creation.**  
Renaming the summary to "Create Project" and the operationId to "createProject" is more intuitive.

---

`44-44`: **Points to the correct response schema.**  
Referencing `CreateProject200ResponseDTO` ensures accurate schema generation in OpenAPI.

---

`52-52`: **Switching to POST method for creation.**  
This aligns with REST best practices for creating resources.

---

`55-55`: **Consumes JSON explicitly.**  
Specifying `consumes = ["application/json"]` helps clarify request format requirements.

---

`68-69`: **Renamed operation to getProjects.**  
This re-labeling avoids confusion and better reflects the API’s purpose.

---

`79-79`: **Response schema references `GetProjects200ResponseDTO`.**  
This is consistent with the newly introduced data class for project retrieval.

---

`87-87`: **Adopts GET method for listing resources.**  
Switching to GET for retrieving projects aligns with standard REST conventions.

---

`91-112`: <details>
<summary>❓ Verification inconclusive</summary>

**Extended query parameters for getProjects.**  
Ensure that these parameters (`parent_id`, `leader_id`, `member_id`, etc.) are documented and tested for edge cases (e.g., negative or null values).

---

```shell
#!/bin/bash
rg -A10 'fun getProjects'
```

</details>

**Attention: Extended Query Parameters Documentation & Edge Case Testing for getProjects**

- The `getProjects` endpoint in `src/main/kotlin/org/rucca/cheese/api/ProjectsApi.kt` is properly annotated with Swagger documentation for parameters like `parent_id`, `leader_id`, `member_id`, etc.
- The implementation in `src/main/kotlin/org/rucca/cheese/project/ProjectController.kt` confirms these parameters are used consistently.
- Please ensure that comprehensive tests are added (or verified) to cover edge cases—such as negative values and null scenarios—for all these query parameters.

</details>
<details>
<summary>src/main/kotlin/org/rucca/cheese/project/ProjectService.kt (5)</summary>

`3-5`: **Relevant imports for date-time and pagination.**  
These imports match the new approach, ensuring the service can handle time calculations and pagination.

---

`21-21`: **Transactional annotation is appropriate.**  
Wrapping project creation in a transaction ensures data consistency.

---

`29-61`: **createProject method ensures ID existence before creation.**  
Calling `teamService.ensureTeamIdExists` and `userService.ensureUserIdExists` helps prevent foreign key errors. Watch for potential performance overhead if called frequently in tight loops.

---

`63-69`: **getProjectDto method ensures NotFoundError is thrown.**  
Throwing a `NotFoundError` is a clear way to handle missing IDs. Good defensive programming.

---

`90-93`: **Enums used for sorting are self-explanatory.**  
Defining separate enum values for `CREATED_AT` and `UPDATED_AT` keeps the code maintainable if more sorting criteria are added in the future.

`29-61`: **Well-structured project creation with proper validation.**

The method properly validates the existence of team and user before proceeding with project creation. The `@Transactional` annotation ensures data consistency.

Two minor suggestions for improvement:


```diff
- return projectRepository.save(project).id!!
+ val savedProject = projectRepository.save(project)
+ return savedProject.id ?: throw IllegalStateException("Project ID should not be null after save")
```

This would make the code more robust by explicitly handling the unlikely case where the ID is null after saving.

`3-20`: **Comprehensive import additions support new functionality.**

The imports demonstrate a well-structured approach to adding pagination, error handling, and service dependencies that align with the new functionality.

---

`24-27`: **Good addition of service dependencies.**

The addition of team and user services as dependencies allows for proper validation of related entities.

---

`63-69`: **Good implementation of project retrieval with proper error handling.**

The method appropriately throws a `NotFoundError` when the project doesn't exist, providing a clear error message.

---

`90-93`: **Appropriate sorting criteria.**

The enum clearly defines the available sorting options for projects.

---

`95-145`: <details>
<summary>❓ Verification inconclusive</summary>

**Well-implemented pagination and filtering.**

The method effectively combines filtering, sorting, and cursor-based pagination. The use of Specification provides a clean way to build complex queries.

There's a potential issue with the member filter:

---

🏁 Script executed:

```shell
#!/bin/bash
# Check implementation of the isMember function used in the specification
echo "Checking for isMember function definition..."
grep -r "fun.*isMember" src/main/kotlin/org/rucca/cheese/

# Check if Project has a members field
echo "Checking if Project has a members field..."
grep -r -A 30 "class Project" src/main/kotlin/org/rucca/cheese/project/ | grep -i "members"
```

Length of output: 345

---

🏁 Script executed:

```shell
#!/bin/bash
# Re-verify isMember function definition using a looser search pattern
echo "Searching for any occurrence of 'isMember(' in the repository..."
rg "isMember\(" -n .

# Re-verify if the 'members' property exists in the Project class
echo "Searching for 'members' property in the Project class file..."
rg "var members" -n src/main/kotlin/org/rucca/cheese/project/Project.kt
rg "val members" -n src/main/kotlin/org/rucca/cheese/project/Project.kt
```

Length of output: 781

---



</details>

**Action Required: Verify the definition of the 'members' attribute in the Project entity.**

The pagination and filtering implementation in `ProjectService.kt` is well-constructed, effectively combining filtering, sorting, and cursor-based pagination via JPA Specifications. The usage of `cb.isMember` leverages the standard CriteriaBuilder functionality. However, our searches did not locate a file named `Project.kt` in the expected directory, so it’s unclear whether the Project entity properly defines the `members` attribute as assumed by the query. Please manually verify that the Project entity exists (potentially in another location) and that it includes a collection property named `members`. If the attribute is defined elsewhere or under a different name, update the specification accordingly.

---

`71-88`: <details>
<summary>❓ Verification inconclusive</summary>

**Well-implemented DTO conversion.**

The extension function provides a clean way to convert a Project entity to its DTO representation.

The repeated null assertions (!!) could potentially be a concern:

---

🏁 Script executed:

```shell
#!/bin/bash
# Check if any of these fields can be null in the database
echo "Checking Project entity for nullable fields..."
grep -r -A 30 "class Project" src/main/kotlin/org/rucca/cheese/project/
```

Length of output: 14195

---



</details>

**Attention: Review the Use of Null Assertions in DTO Conversion**

The extension function for converting a Project to a ProjectDTO is implemented clearly and maps fields appropriately. However, the repeated use of `!!` (null assertions) across several fields (e.g., `id`, `name`, `description`, `colorCode`, `startDate`, `endDate`, etc.) remains a potential risk. Although your JPA annotations (such as `@Column(nullable = false)`) suggest these fields should not be null in the database, the Kotlin types are still declared as nullable. This mismatch could lead to runtime exceptions if any field unexpectedly remains null.

**Recommendations:**
- **Consider safer alternatives:** Instead of using `!!`, you might use `requireNotNull` with informative error messages to help diagnose issues earlier in case any field is unexpectedly null.
- **Revisit entity nullability:** Evaluate whether it’s feasible to update the Kotlin entity’s field types to non-nullable to align with the database constraints, reducing the need for null assertions.

Please verify that these adjustments align with the overall design and error-handling strategy for the codebase.

`29-61`: **Consider using a builder pattern or data class for createProject parameters**

The method signature is quite lengthy with 11 parameters, which can make it difficult to maintain and call. Consider using a builder pattern or a dedicated DTO/data class to handle these parameters more elegantly.

```kotlin
// Example using a Kotlin data class
data class ProjectCreationParams(
    val name: String,
    val description: String,
    val colorCode: String,
    val startDate: LocalDateTime,
    val endDate: LocalDateTime,
    val teamId: IdType,
    val leaderId: IdType,
    val content: String,
    val parentId: IdType? = null,
    val externalTaskId: IdType? = null,
    val githubRepo: String? = null,
)

@Transactional
fun createProject(params: ProjectCreationParams): IdType {
    teamService.ensureTeamIdExists(params.teamId)
    userService.ensureUserIdExists(params.leaderId)
    // Rest of the implementation
}
```

Using GET is aligned with the standard for read (list) endpoints.

---

`91-111`: **Refined getProjects function signature.**  
The parameters now accurately capture optional filters (parentId, leaderId, memberId) and pagination data.

</details>
<details>
<summary>design/API/NT-API.yml (6)</summary>

`2484-2484`: **New operationId for project creation.**  
Defining `create-project` clearly separates it from other operations.

---

`2499-2499`: **Added required field `teamId`.**  
Ensuring `teamId` is mandatory strengthens the relationship between a project and its team.

---

`2518-2520`: **Team ID property definition.**  
Declaring `teamId` as a 64-bit integer is consistent with other ID fields.

---

`2567-2567`: **New operationId for listing projects.**  
Giving a distinct `get-projects` operationId clarifies the endpoint's function.

---

`4151-4152`: **Added `team` and `leader` to Project’s required fields.**  
Teachers clarity that these relationships must be present for a valid project.  

Do you confirm that these fields are always guaranteed to be non-null from the data layer?

---

`4177-4180`: **Introduced references to `Team` and `User` in Project schema.**  
Changes the project model to strongly reference related entities.

</details>
<details>

All necessary fields (e.g., `teamId`, `leaderId`) are mapped to `projectService.createProject`.

---

`37-38`: **Guard annotation for enumerating projects.**  
The `@Guard("enumerate", "project")` clarifies role-based access for reading projects.

---

`42-44`: **Defined optional filter parameters and page sizing.**  
The function parameters align with the new getProjects request specification.

---

`45-46`: **Potential redundancy flagged previously.**  
These local vars (`sortBy`, `sortOrder`) might move into `enumerateProjects` or be constants.

---

`48-56`: **Refined call to `enumerateProjects`.**  
Parameters match the newly introduced filters and sorting logic.

---

`59-61`: **Returning new GetProjects200ResponseDTO structure.**  
Demonstrates a clear, typed response with relevant pagination info.

</details>
<details>
<summary>src/main/kotlin/org/rucca/cheese/project/ProjectService.kt (4)</summary>

`95-142`: **Ensure proper pagination and sorting with the cursor-based approach**

The implementation of cursor-based pagination with sorting seems well-structured, but you should verify that the sorting correctly respects the provided direction and that the cursor behavior works as expected, especially with different sort orders.

---

`43-44`: **Good validation practice for team and user existence**

Using dedicated service methods to validate the existence of related entities before proceeding is a good practice for maintaining data integrity.

---

`29-29`: **Appropriate use of @Transactional annotation**

The `@Transactional` annotation ensures that database operations are atomic, consistent, isolated, and durable, which is essential for methods that modify data.

---

`123-123`: <details>
<summary>✅ Verification successful</summary>

**Verify the cb.isMember() method usage**

The `cb.isMember()` method doesn't appear to be a standard method in the JPA Criteria API. Please verify if this is a custom extension or if there's an alternative standard approach.

---

🏁 Script executed:

```shell
#!/bin/bash
# Check for custom implementations of isMember
rg "def.*isMember" --type kotlin

# Check for imports or usages of criteria-related classes
rg "import.*criteria" --type kotlin
```

Length of output: 2625

---



</details>

**Subject: Validated Standard Usage of `cb.isMember()`**

After running the verification scripts, no custom implementation of `isMember` was found. The method is indeed part of the standard Jakarta Persistence Criteria API and is correctly used in the provided context.

**Potential type conversion issue with leaderId.toInt()**

Converting `leaderId` (of type `IdType`) to `Int` might lead to data loss if `IdType` is a `Long` or another numeric type that can exceed the range of `Int`. Consider using a safer conversion method or restructuring the model to avoid this conversion.

---

🏁 Script executed:

```shell
#!/bin/bash
# Check the definition of IdType
rg "typealias IdType" -A 1

# Check if User's id field is Int in the model definition
rg "class User" -A 10
```

Length of output: 10979

---



</details>

**Action Required: Address Unsafe Conversion from Long to Int**

- The code converts `leaderId` (an alias for `Long`) to an `Int` with `toInt()` without validating that the value fits within the `Int` range.
- This pattern is consistent in other parts of the code (e.g., in `UserService.kt`), but it introduces a risk of data loss or runtime issues if `leaderId` exceeds `Int` limits.
- Consider either:
  - Adding a validation check to ensure `leaderId` is within `Int` bounds before converting (e.g., using a conditional check and throwing an exception for out-of-range values);
  - Or updating the model to use `Long` consistently for user identifiers if the overall system design permits.

**Excessive use of non-null assertions (!!) may lead to runtime exceptions**

The extension function uses multiple non-null assertions that could lead to NullPointerExceptions if any of the properties are null. Consider using safe calls (?.) with default values or explicit null checks.

## Walkthrough
This pull request refactors the project-related API and backend code. The OpenAPI spec for the `/projects` endpoint has been updated with new operation IDs, mandatory parameters (including `teamId`), and revised schema relationships. The Projects API interface, controller, service, repository, and model (DTO) classes have been modified to separate project creation from project retrieval, with refined parameter handling and response structures. Additionally, new methods for validating team and user existence and for paginating projects have been added, along with corresponding tests.

## Changes

| File(s) | Change Summary |
|---------|----------------|
| `design/API/NT-API.yml` | Updated OpenAPI spec: Added `create-project` for POST, `get-projects` for GET, included required `teamId` in request body, and replaced `leaderId` with `leader` and `team` in `Project` schema. |
| `src/main/kotlin/org/rucca/cheese/api/ProjectsApi.kt` | Refactored API: Removed `projectsGet`, added `createProject`, and renamed `projectsPost` to `getProjects` with updated DTO usage. |
| `src/main/kotlin/org/rucca/cheese/model/*` | Renamed and updated DTO/model classes: Updated class names (e.g., `ProjectsPost200ResponseDTO` → `CreateProject200ResponseDTO`, `ProjectsGet200ResponseDTO` → `GetProjects200ResponseDTO`), added `teamId` to request DTOs, and replaced `leaderId` with `leader` and `team` in `ProjectDTO`. |
| `src/main/kotlin/org/rucca/cheese/project/ProjectController.kt`, `ProjectEntity.kt`, `ProjectService.kt` | Controller and service refactor: Updated method signatures for project creation and retrieval; modified repository inheritance to use `CursorPagingRepository`; added new methods (`getProjectDto`, `enumerateProjects`, conversion extension) and a new sorting enum. |
| `src/main/kotlin/org/rucca/cheese/team/TeamService.kt`, `src/main/kotlin/org/rucca/cheese/user/RolePermissionService.kt`, `src/main/kotlin/org/rucca/cheese/user/UserService.kt` | Added validations and permissions: Introduced `ensureTeamIdExists` in TeamService, `ensureUserIdExists` in UserService, and a new project-related permission in RolePermissionService. |
| `src/test/kotlin/org/rucca/cheese/api/ProjectTest.kt` | Added new test class for validating project creation and retrieval endpoints under test conditions. |

### Chat

There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai?utm_source=oss&utm_medium=github&utm_campaign=SageSeekerSociety/cheese-backend-nt&utm_content=172):

- Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  - `I pushed a fix in commit <commit_id>, please review it.`
  - `Generate unit testing code for this file.`
  - `Open a follow-up GitHub issue for this discussion.`
- Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples:
  - `@coderabbitai generate unit testing code for this file.`
  -	`@coderabbitai modularize this function.`
- PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  - `@coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.`
  - `@coderabbitai read src/utils.ts and generate unit testing code.`
  - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.`
  - `@coderabbitai help me debug CodeRabbit configuration file.`

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

### CodeRabbit Commands (Invoked using PR comments)

- `@coderabbitai pause` to pause the reviews on a PR.
- `@coderabbitai resume` to resume the paused reviews.
- `@coderabbitai review` to trigger an incremental review. This is useful when automatic reviews are disabled for the repository.
- `@coderabbitai full review` to do a full review from scratch and review all the files again.
- `@coderabbitai summary` to regenerate the summary of the PR.
- `@coderabbitai generate docstrings` to [generate docstrings](https://docs.coderabbit.ai/finishing-touches/docstrings) for this PR.
- `@coderabbitai resolve` resolve all the CodeRabbit review comments.
- `@coderabbitai configuration` to show the current CodeRabbit configuration for the repository.
- `@coderabbitai help` to get help.

### Other keywords and placeholders

- Add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed.
- Add `@coderabbitai summary` to generate the high-level summary at a specific location in the PR description.
- Add `@coderabbitai` anywhere in the PR title to generate the title automatically.

### CodeRabbit Configuration File (`.coderabbit.yaml`)

- You can programmatically configure CodeRabbit by adding a `.coderabbit.yaml` file to the root of your repository.
- Please see the [configuration documentation](https://docs.coderabbit.ai/guides/configure-coderabbit) for more information.
- If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: `# yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json`

### Documentation and Community
