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.

Strategy 1: Hardcoded System Prompts (Static)

  • 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.

Example:

summarizer_prompt = "You are a professional summarizer. Always produce concise, accurate summaries."
llm_summarizer = LLM(prompt=summarizer_prompt)

Strategy 2: Dynamic Prompts (Context-Aware)

  • 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.

Example:

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))

Hybrid Strategy: Static Core + Dynamic Augmentation

  • Combine a stable role definition with runtime context injection.
  • Keeps behavior interpretable while increasing flexibility.

Example:

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))
