How to use Claude Code subagents to parallelize development

Slightly off topic but I would really like agentic workflow that is embedded in my IDE as well as my code host provider like GitHub for pull requests.

Ideally I would like to spin off multiple agents to solve multiple bugs or features. The agents have to use the ci in GitHub to get feedback on tests. And I would like to view it on IDE because I like the ability to understand code by jumping through definitions.

Support for multiple branches at once - I should be able to spin off multiple agents that work on multiple branches simultaneously.

Would that be solved by having several clones of your repo, each with a IDE and a Claude working on each problem? Much like how multiple people work in parallel.
