PromptFragmentationsverteilung

PromptFragment is a descriptive term used in the field of prompt engineering to denote a fragment of a prompt that can be combined with other fragments to form a complete instruction or query for a language model. A prompt fragment typically contains one or more of the following elements: role guidance, stylistic constraints, background or context, and task instructions. By composing a library of fragments, practitioners can assemble prompts quickly, reuse proven guidance, and experiment with different formulations without rewriting from scratch.

Design and use: Fragments are often stored as templates with placeholders such as {topic} or {audience}, enabling dynamic substitution. They can be categorized as instruction fragments, which tell the model what to do; context fragments, which provide background; and constraint fragments, which limit scope, length, or tone. Effective use requires alignment among fragments so that combined prompts remain coherent and do not conflict.

Benefits and considerations: The modular approach improves consistency, reduces cognitive load, and accelerates iteration. However, fragmentation can introduce contradictions if fragments are not synchronized, and over-segmentation may hinder global coherence. It also increases reliance on token budgets and requires careful maintenance of the fragment library to avoid stale or biased guidance.

Example: A simple fragment might read "You are a concise, helpful assistant." Another fragment might read "Explain the topic in lay terms suitable for a beginner." These can be mixed to tailor prompts.
