Yes, you can run frontend and backend agents simultaneously when their tasks are scoped clearly and their changes are isolated. This is one of the most natural uses for parallel AI coding because frontend and backend work often move in related but separable paths.
A safe setup starts with a shared contract. Define the API shape, data model, validation rules, and expected UI states before launching both agents. Then one agent can build or update backend logic while another implements the frontend integration. Tests or mocks should verify that both sides still match.
Verdent is well suited to this pattern because Plan Mode can define the task split before execution, and Workspace Isolation can keep each worker's changes separate. The final step is human review: compare diffs, run integration checks, and merge only once the contract holds.
