Prompt engineering across the ecosystem.

Start with the versioned-template workflow to define an evaluation before editing a prompt. Then use structured outputs to make the consumer contract explicit. Tool calling completes the path by showing how a model-generated object becomes a proposal that your application must validate and authorize.

Use this collection to compare how the same design question changes across tasks. Read the source-backed explanation before adapting an example. Identify which assumptions apply to your environment, which information is unavailable, and which checks must remain in ordinary application code. A reference pattern is a starting point for that review, not evidence that a connected service or deployment already exists.

Keep a small set of difficult cases as you explore: an incomplete input, conflicting evidence, a changed permission, and an operation whose result is uncertain. Record what should happen in each case. When you finish a guide, revisit those expectations instead of judging the design only by its most fluent answer. The linked articles offer complementary perspectives, so a useful reading order follows the consequences of your task rather than the publication date alone.
