The short answer
Abdul Osama is not saying to stop giving AI instructions. His point is to stop starting every task from zero. Context engineering means selecting relevant project information and making it available to an AI agent so it can interpret a request in light of that information, rather than relying on a polished prompt alone.
Instead of starting every conversation from scratch, there should be full context for the project. — Abdul Osama
From writing prompts to preparing context
Prompt engineering is the practice of shaping instructions for an AI model. An AI agent is a system that uses a model to carry out tasks with the instructions, context and resources available to it. Abdul says an agent becomes more useful when it already has the project information needed to solve a problem, write an email or draft a marketing plan.
| Approach | What informs the response | | --- | --- | | A chat started from scratch | The current request and whatever you explain in that conversation | | An agent equipped with project context | The current request plus relevant project information |
Depending on the task, Abdul suggests providing project documentation, brand information, target-audience details and past customer conversations. For software projects, he adds the code, project structure, previous problems and how they were solved. Market, competitor, pricing and goal information can also help make a response specific to the business.
His distinction is that context engineering does not mean giving an agent everything you have. It means choosing what is relevant, so a short instruction such as “write this email” can produce work grounded in the project rather than a generic template.
In numbers
- Abdul contrasts the prompt-writing approach common in 2024 or 2025 with the approach he advocates in 2026.
- He says some models' context windows can reach a million tokens or more; this is not a fixed capability of every model.
Background
A context window is the amount of text and other information a model can handle within its technical limits for a request. A large window does not automatically give an agent access to your files or customer conversations. That information must be made available with appropriate permissions and attention to privacy.
What to do next
Define the task, then select only the documents and details it needs. Abdul mentions ChatGPT, an AI chat assistant, and Claude, another AI assistant, as examples when discussing where to learn context engineering.
