🤖Prompt Engineering: Prompting (Just the Quotes)

"A prompt is a piece of text - questions, thoughts, ideas, or phrases - that you give to the model as a starting point for generating text. A prompt can be a short question, or it can be paragraphs in length." (TJ Books, "Create Highly Effective Prompts, Strategies, and Best Practices to From Novice to Expert", 2023)

"As the tech industry moves from non-generative models to generative models, it is shifting away from feature engineering, or creating features to model the data and experimenting with different hyperparameters to optimize performance. Generative models, and specifically LLMs, do not require feature engineering. Today, the core requirements are usually prompt engineering or building a RAG pipeline - skills that lie within the domain of AI engineers." (Abi Aryan, "LLMOps: Managing Large Language Models in Production", 2025)

"In prompt engineering, we customize the prompts or questions we give the model to get more accurate or insightful responses. The way a prompt is structured has a massive impact on how well a model understands the task at hand and, ultimately, how well it performs. Given LLMs’ versatility, prompt engineering has become an important skill for getting the most out of these models across different domains and tasks. The key is to understand how different prompt structures lead to different model behaviors. There are various strategies - ranging from simple one-shot prompting to more complex techniques like chain-of-thought prompting - that can significantly improve the effectiveness of LLMs." (Abi Aryan, "LLMOps: Managing Large Language Models in Production", 2025)

"[...] prompt engineering, the science and art of crafting the text inputs that are sent to the models. Prompt updates can significantly improve or degrade the user experience. But prompt engineering is iterative and can be difficult to master and document, especially with closed-source LLMs." (Abi Aryan, "LLMOps: Managing Large Language Models in Production", 2025)

"Professional software developers must know how to use AI tools strategically.  This involves mastering advanced prompting techniques and working with AI across various files and modules. We must also learn how to manage context wisely. This is a new concept for most, and it is vitally important with code generation. AI-generated code requires the same scrutiny and quality checks as any code written by humans." (Jeremy C Morgan, "Coding with AI: Examples in Python", 2025)

"Prompt engineering is a crucial aspect of working with large language models (LLMs) like OpenAI's GPT, Google's PaLM, and others in the space of AI and machine learning. It involves the art and science of designing inputs (prompts) in a way that maximizes the quality, relevance, and accuracy of the AI-generated output. As the capabilities of AI continue to improve, the task of crafting effective prompts has become an essential skill for anyone leveraging these tools for real-world applications, including natural language understanding, translation, summarization, code generation, and more." (Code Planet, "Python for Large Language Models", 2025)

"Prompt injection is a security vulnerability that is specific to AI systems, especially LLM systems, in which malicious users try to manipulate prompts to make a model behave in a certain unintended way. They may try to get it to leak data, execute unauthorized tasks (especially with agentic systems), or ignore constraints. This is possible because LLMs are typically encapsulated inside applications using metaprompts, which are developer-created instructions that define the model’s behavior. Metaprompts usually contain safeguard instructions, such as 'do not use curse words', and placeholders where the input submitted by the user is pasted. The user’s input is combined with the metaprompts into a larger prompt that then goes to the model." (Abi Aryan, "LLMOps: Managing Large Language Models in Production", 2025)

"Recursive prompting is a systematic approach to achieving higher-quality outputs through iterative refinement. Rather than accepting the first response, it uses a step-by-step process of evaluation and improvement, making it particularly valuable for complex tasks such as code development, writing, and problem-solving. Our example demonstrated how a basic factorial function evolved from a simple implementation to a robust, optimized solution through multiple iterations of targeted refinements." (Jeremy C Morgan, "Coding with AI: Examples in Python", 2025)

"The simplest form of an agent is little more than a wrapped prompt. It takes an input, does some local reasoning, returns an output, and exits. There’s no memory, no iteration, no 

feedback loop. These are useful when the task is bounded, like generating a SQL query, converting a paragraph to a tweet, or answering a direct question. But single-step agents 

are brittle. They assume everything is known up front. They can’t handle surprises or partial failures. You’ll quickly outgrow them when tasks involve multiple actions or require state tracking." (Abi Aryan, "LLMOps: Managing Large Language Models in Production", 2025)

"With MCP, a model no longer has to guess what’s possible. Instead, it can discover tools, query data sources, and select prompts - all in real time, all through a shared protocol. This means a model doesn’t just generate responses; it acts, it calls tools, it gathers context, and it learns how to interact with the outside world in a modular,controlled way." (Abi Aryan, "LLMOps: Managing Large Language Models in Production", 2025)
