      summary: GitHub Get All Repository Topics
      description: This GET endpoint retrieves all topics associated with a specific GitHub repository. Topics are labels that help categorize and organize repositories, making them more discoverable to users searching for projects with particular technologies, frameworks, or subject matters. By calling this endpoint with the repository owner's username and the repository name, you can fetch the complete list of topics currently assigned to that repository. The response includes an array of topic names that have been added by repository maintainers to describe the repository's purpose, technology stack, or relevant themes. This endpoint is useful for applications that need to display repository metadata, build topic-based navigation systems, or analyze repository categorization across multiple projects.

      summary: GitHub Replace All Repository Topics
      description: The Replace All Repository Topics operation is a PUT request to the GitHub Repos API endpoint /repos/{owner}/{repo}/topics that allows you to completely replace the existing list of topics associated with a specific repository. Unlike adding or removing individual topics, this operation overwrites all current topics with the new set provided in the request body. You must provide the repository owner's username and the repository name in the URL path, along with authentication credentials that have the necessary permissions to modify repository settings. The request body should contain a JSON object with a "names" array listing all the topics you want to assign to the repository, where topics are short descriptive keywords that help categorize and improve discoverability of the repository on GitHub.
