- Write clear prompts with explicit completion criteria — the clearer the task, the higher the success rate, especially for complex work.

- Make tasks easy to verify — e.g. checking that CI passes or testing an automatic deployment.

- For harder tasks, break them into well-scoped steps and provide relevant context or examples.

- Follow our best practices and pre-task checklist.

- Tagging Devin on a Slack or Teams thread about a bug you’re discussing with coworkers

- Delegating a more complex task via the web application and taking over in Devin’s IDE once it gives you a good first draft.

- Running Devin for Terminal in your local environment for quick fixes, code exploration, and interactive coding right from the command line — then using /handoff to send longer tasks to cloud Devin.

/handoff

- Carving out tasks from your todo list at the start of your day and returning to draft PRs waiting for review.
