Whether it's delegating frontend tasks, fixing bugs, or building internal tools, Devin works in all the tools where we collaborate with the rest of the team. Here are some examples of good ways to work with Devin: * Tag Devin on a [Slack](/integrations/slack) or [Teams](/integrations/microsoft-teams) thread about a bug you're discussing with coworkers * Delegate a task like a refactor in your IDE to save you from context switching (something you would have normally just added to your backlog) * Kick off multiple sessions with the long tail of your todo list at the beginning of the day and return to draft PRs waiting for review around lunch * Tag Devin on feature requests or issues raised by customers in your shared Slack or Teams channels ### Devin 2.0 IDE Walkthrough
