10 Prompt Skills for ChatGPT, Claude, and Gemini
A brief guide presenting 10 reusable AI prompt 'skills' designed for ChatGPT, Claude, and Gemini. Each skill is delivered as a standalone .md prompt that encodes a concrete methodology (named frameworks like SCQA, PAS, AIDA), measurable constraints (for example: "first sentence must be under 12 words"), and structured output formats. The approach aims to change model output structure through completion criteria and strict constraints so outputs require less editing. The skills span writing, copywriting, research, video production, code review, competitive analysis, and workflow planning, and are intended to be copy-paste ready into major LLMs.
Practical guide for prompt engineering that can improve creative and operational workflows using LLMs, but it is a how-to resource with limited direct, immediate impact on the AdTech/MarTech industry at large.

Key Takeaways & Evidence Grounding
- The author publishes 10 AI prompt skills provided as self-contained .md files for use with ChatGPT, Claude, and Gemini.
- Skills encode named frameworks such as SCQA, PAS, and AIDA, measurable constraints (e.g., sentence length rules), and structured output formats.
- The prompt skills target multiple use cases including writing, copywriting, research, video production, code review, competitive analysis, and workflow planning.
- The methodology emphasizes completion criteria and strict constraints (e.g., severity ratings, evidence grades, "done when" criteria) to produce more usable model outputs.

ChatGPT Prompt Engineering Guide for Freelancers
This how-to article explains ChatGPT prompt engineering for freelancers, covering goals, prompt structures, refinement techniques, and monetization opportunities. It defines prompt engineering as crafting inputs that produce specific, accurate responses from ChatGPT and recommends a three-step workflow: (1) define the objective, (2) choose a prompt structure (zero-shot, few-shot, chain-of-thought), and (3) refine prompts by adding examples, output format specifications, and constraints. The piece includes practical code examples (a Python function to compute a rectangle area and a NumPy variant) and suggests freelancers can monetize prompt-engineering skills by automating tasks, generating content, and offering services to clients.
15 ChatGPT Prompts to Save Time
OnlineMarketing.de surveys 15 ChatGPT prompts designed to boost productivity by saving time across marketing and content tasks. The prompts span categories such as explaining complex topics to lay audiences, Critique mode for rigorous feedback, Expert Interview simulations, Meeting Preparation, Reverse Briefs, Research Synthesis, Decision Matrices, Jargon Translation, Email drafting, Code explanations, Idea stress tests, Content repurposing for multiple formats, Learning paths, Analogies generation, and Second-Order Thinking. Each prompt explains its function and why it enhances efficiency—reducing unnecessary detail, surfacing risks earlier, and enabling multi-format outputs from a single source. The article notes that context and iterative tuning improve results (per zmilesbruce) and suggests adapting examples for other chatbots like Claude and Gemini. It also references Agentic Workflows with ChatGPT, implying potential time savings of about 10 hours per week. The piece was first published January 23, 2026, by OnlineMarketing.de.
Prompts to Teach LLMs Your Writing Style
t3n published a how-to article describing two prompt templates (a short and a detailed variant) to help users analyze and transfer their personal writing tone to AI chatbots such as ChatGPT and Claude. The piece references a t3n MeisterPrompter podcast episode that provides the templates and instructions — including attaching 3–5 documents for analysis and exporting the AI's tonality analysis as a reusable PDF. Co-host Susanne Renate Schneider recommends a quick prompt: “Please analyze my tonality and describe it in five words.” The article also notes that the publisher used its internal AI tool to produce the text and includes third-party promotional content from TargetVideo GmbH and Podigee GmbH.
