<requirements>
*   **Identify Key Changes:** Focus on the most significant updates. Aim to cover 3-5 key areas of improvement or new functionality.
*   **Explain Impact:** For each change, briefly explain *why* it was made and *how* it benefits the user. For instance, instead of just saying "Improved performance," state "Improved performance by optimizing database queries, resulting in faster load times for key features."
*   **Provide Specific Examples:** Where applicable, include 1-2 concrete examples for major features or bug fixes to illustrate the change.
*   **Maintain Clarity:** Keep explanations accessible and easy to understand, as the audience may include users with varying technical backgrounds. Avoid overly technical jargon.
*   **Structure Logically:** Organize the changelog with clear headings for different types of changes (e.g., "New Features," "Improvements," "Bug Fixes").
*   **Concise Descriptions:** While providing thorough explanations, ensure each point is concise and to the point. Aim for 2-4 sentences per item.
*   **Positive Framing:** Present changes in a positive light, highlighting progress and benefits.

</requirements>

<format>
*   Use Markdown for formatting.
*   Employ clear headings for sections like "What's New," "Improvements," and "Bug Fixes."

Why This Claude Prompt for “Write a Changelog” Works Better

When you type “Write a changelog for the new version of my app” into Claude, it lacks structure — Claude has to guess what format you want, how detailed to go, and what to prioritize. The optimized version removes that guesswork.

It wraps the request in XML tags (<task>, <requirements>, <format>) that Claude uses to separate context from instructions. It also explains WHY behind each constraint — Claude produces better results when it understands your reasoning.
