Give your coding agent a finish line
Background coding tools are getting more capable. The brief still determines whether their work is useful.
Beyond autocomplete
GitHub’s February 2026 coding-agent update describes model selection, self-review, security scanning, custom agents, and handoff between cloud and local workflows. The product is built around delegated work returning as a pull request. That changes the interaction: you are defining a piece of work another process can complete, rather than accepting suggestions one line at a time.
Make completion observable
A useful task explains the trigger, the expected behavior, and the constraints. “Fix the settings page” leaves too many decisions open. “Saving a changed display name should update the account header, preserve the other fields, and show an inline error if the request fails” gives the implementation something observable to satisfy. Point to an existing pattern and say which checks should prove the result.
Our take
Begin with bounded changes that a person can review in one sitting. Keep access to production systems separate from the coding task, and review the actual diff and test evidence. Agent self-review is useful feedback, but it is not independent approval. The practical measure is the time from a clear request to a change your team understands and accepts, including the corrections along the way.
Put it into practice.
Write the acceptance criteria before starting the agent. Require an explanation of the changed behavior and the checks performed alongside the code.
