1. Chain-of-Thought Prompting

Forcing LLMs to produce step-by-step reasoning before delivering a final verdict dramatically reduces logic errors. Include explicit instructions such as: "Think step by step in XML tags before providing the output."

2. Role Framing & Persona Definition

Establish exact expert parameters to calibrate tone, vocabulary, and depth. Contrast standard queries with calibrated role prompting:

Role: Senior Principal Cybersecurity Auditor.
Task: Review the following AWS IAM policy for privilege escalation vulnerabilities.
Output format: Markdown table with Severity, Resource, Vector, and Remediated JSON snippet.

3. Few-Shot Contextual Formatting

Provide two to three clean examples directly inside the system message to enforce strict output schemas without depending solely on instruction descriptions.
