Google Prompting Essentials Course Highlights (Prompt Framework / 4 Iteration Methods / Prompt Chaining / High-Frequency Scenario Playbooks)
A self-contained bilingual highlight of Google’s official Prompting Essentials course. The core is the 5-element prompt framework TCREI (Task / Context / References / Evaluate / Iterate, with the mnemonic Thoughtfully Create Really Excellent Inputs), which frames writing prompts as equivalent to writing a clear brief for a new hire. It covers: 4 iterative fix methods (return to the framework / split long prompts / switch to a similar task / add constraints) and chain-of-density summarization; prompt chaining, which uses the previous step’s output as the next step’s input, distinguished from simple iteration, including chain-of-thought / tree-of-thought variants; reusable prompt skeletons for 6 high-frequency office scenarios (brainstorming / table trackers / meeting notes / data visualization / text-to-image / presentation speaker notes), plus email writing / summarization / tone and style / multimodal prompts / meta-prompts / decoding formulas and jargon; and a human-in-the-loop checklist for responsible AI use (preventing hallucinations / preventing bias / protecting data). It complements [[newtype-prompt-engineering]]: while Lao Huang’s piece takes the contrarian stance that “prompt engineering doesn’t need to be studied” and covers product-grade prompt orchestration, this article provides Google’s official standardized framework and scenario templates, suitable for non-technical PMs to use immediately as a starting point.
