Coordinate sub-agents to monitor PRs and fix prod bugs
A Cursor Projects coordinator agent delegates to sub-agents, watches new PRs and production bugs, spins up agents to fix issues, and surfaces questions to the user.
Lumos used Devin for routine tasks like MUI-to-Tailwind conversion, which went well, and its unit-test feedback loop reduced rewrites.
Lumos used Devin for routine tasks like MUI-to-Tailwind conversion, which went well, and its unit-test feedback loop reduced rewrites.
Lumos engineers gave Devin a short prompt to convert React MUI components to Tailwind using their own styles, and it opened a PR. Before that, they let it run unit tests and filled its Knowledge feature with codebase-specific guidance. Engineers then reviewed the PR.
The conversion went quite well, but the PR wasn't ready to merge as-is. They think linting and pre-commit hooks might have fixed that. Overall, Devin pushed 44 PRs in 48 days, and 19 were merged.
Typical Devin PRs cost $5 to $40, averaging about $20. Each command is capped at 10 ACUs (about $20), and a simple deletion PR cost about $5.
In [repo name], convert the React components in [folder path] from [current styling library, e.g. MUI] to [target, e.g. Tailwind], keeping the look and behavior the same. Run the existing unit tests after each component and fix failures before moving on. Open a PR when all tests pass, with a short list of components converted and anything you couldn't convert.

Ran a Cursor agent continuously for 24 hours to build a project management tool; the app fully works but is not production ready.
