When designing agent specialization through system prompts, the choice between hardcoding prompts at setup and dynamically generating them at runtime often depends on the required flexibility, interpretability, and control.
- Use Case: When agents serve stable, well-defined roles.
- Advantages:
- Easy to audit and debug.
- Predictable behavior.
- Simpler deployment.
- Disadvantages:
- Less adaptive to user-specific or context-specific needs.
summarizer_prompt = "You are a professional summarizer. Always produce concise, accurate summaries."
llm_summarizer = LLM(prompt=summarizer_prompt)
- Use Case: When the agent’s role or task details shift based on runtime data, user input, or evolving goals.
- Advantages:
- Highly adaptable to complex or fluid task environments.
- Enables intelligent task personalization.
- Disadvantages:
- Harder to predict behavior.
- Requires careful input sanitization and prompt engineering.
def generate_prompt(user_goal):
return f"You are an expert assistant helping the user achieve the goal: '{user_goal}'. Provide actionable and concise guidance."
llm_agent = LLM(prompt=generate_prompt(user_input))
- Combine a stable role definition with runtime context injection.
- Keeps behavior interpretable while increasing flexibility.
base_prompt = "You are a legal advisor."
def contextualize(base, context):
return base + f" The current topic is: {context}"
llm_legal_agent = LLM(prompt=contextualize(base_prompt, user_topic))

This diagram illustrates how a prompt-generation system can choose between static and dynamic prompt construction paths before routing the prompt to the specialized agent.
