Prompt engineering guides
Practical, no-fluff guides to writing prompts that work — and keep working. From the fundamentals to structured outputs, evals, reasoning models, and running prompts in production.
Fundamentals
Prompt engineering best practices
The core habits: be specific, give structure, show examples, and constrain the output.
Designing system prompts
Set role, rules, and format once so every call behaves consistently.
Few-shot prompting
Teach the pattern with examples — how many, how to pick them, and when to stop.
