Who this page is for
The useful test is practical, not theatrical. A small team needs evidence it can review later: what was checked, which source supported it, what stayed uncertain, and who owned the final decision. For this coding agent workflow, the section focus is fit. Write the result in plain language. Do not hide weak evidence behind a confident paragraph. If the vendor page, help article or repository does not answer the question, mark that as an open item for the demo or procurement call.
The point is not to crown a winner. The point is to reduce the chance that a glossy AI answer, demo video or social thread becomes a buying decision without a trail. Keep the check small enough to repeat: one task, one owner, one evidence note, one decision. If the result cannot be explained in two minutes, the team has not finished the evaluation.
