When doing Coze, it's normal for many people to tune the prompt first at the beginning. But when there is more and more information and the answers are more and more likely to deviate, the question is no longer whether the prompt is long enough, but whether it is time for you to go to the knowledge base. For Coze, the knowledge base is not an "advanced decoration", but a key step in getting agents to really rely on your data to answer.
Simply put: prompts are more suitable for writing rules, tone, and characters; Knowledge bases are more suitable for documents, materials, FAQs, product descriptions, and internal knowledge. The two are not substitution relationships, but different divisions of labor.
When to always consider the knowledge base
- You want it to answer your own information first, rather than relying on models in general.
- You already have a batch of documents, manuals, instructions, course materials, or business materials.
- You find the same question, and it doesn't answer consistently every time.
Don't rush to add it first
If your Coze is mainly about idea generation, light chat, and character interaction, the knowledge base may not be the first priority. Because at this time, the focus is not on accurate citation of information, but on output style and dialogue experience.
The most common misconceptions
Many people will stuff everything into prompts, and as a result, the prompts become longer and longer, and the control is getting worse and worse. Others in turn use the knowledge base as a panacea, uploading a bunch of information without organizing the structure, and finally still missing the key points. The really effective way is: put the prompt in the rules and the facts in the knowledge base. The more information, the more important this division of labor is.
From the perspective of user experience, the knowledge base also has a practical advantage: when the data is updated later, you change the information itself, instead of rewriting the entire prompt every time. This is much easier for Coze for long-term maintenance.
Summary in one sentence
If you want Coze to answer more like "know your data" rather than "guess okay", then the knowledge base is usually worth opening. Continuing to pile prompts can solve some problems, but in data-based scenarios, knowledge bases are a more stable way.
