Choose an agent for the task
Compare the work you need done, the tools available and the result you can verify.
Start with the work
A small UI change, a repository investigation and a multi-file refactor need different levels of context and review. Write down the expected result before choosing an agent or model.
Check the actual connection
An installed coding agent and an API model are different connections. File, terminal and browser tools depend on the selected execution environment and integration. Check readiness and project access in VECTA before starting.
Compare one bounded task
Use a small, representative change with the same acceptance criteria. Review the changes and checks alongside reported tokens, cost and time. A faster reply is not necessarily a finished task.
