We use Claude Code at work, but the useful part is not asking it to write a lot of code quickly. The useful part is putting it inside a workflow where its changes can be inspected, tested, and rejected when they do not meet the requirements.
Loop mode is a workflow, not a shortcut
Loop mode is most useful when the task has a clear definition of done and a reliable way to check it. The agent can make a change, run the checks, inspect the result, and continue. Without those boundaries, a loop just produces more activity.
Agents need a narrow job
We get better results when an agent has one responsibility and a concrete handoff. An agent that discovers the problem should not automatically be the agent that changes production configuration. Separating investigation, implementation, and review makes mistakes easier to see.
Guard rails are part of the design
Repository instructions, allowed tools, protected environments, review requirements, and tests are not obstacles around the workflow. They are the workflow. The goal is to make the safe path the easy path and the risky path obvious.
TDD by design
Tests are especially valuable when an agent is involved because they turn an ambiguous request into an executable constraint. We try to establish the expected behavior first, then let the implementation change until the tests pass. That does not eliminate judgment, but it gives the agent a feedback signal better than prose alone.
The recurring lesson is simple: give the agent enough autonomy to make progress, but not enough ambiguity to invent the project.
Current as of September 2026. This describes our engineering practice, not a universal Claude Code configuration.
