<verification> Run the existing changelog generation script or tool to ensure the new entry is correctly formatted and appended. Verify that the changelog accurately reflects the changes introduced in the new version, including new features, bug fixes, and breaking changes. </verification> <outcome> A comprehensive and well-formatted changelog entry for the new application version is created and added to the existing CHANGELOG.md file. The entry should clearly detail all significant changes since the last release. </outcome> <context> Review the existing entries in CHANGELOG.md to understand the established format, tone, and level of detail. Examine the commit history and recent pull requests to identify all user-facing changes, bug fixes, and improvements that need to be documented. </context> <constraints> Do not alter the existing format or structure of the CHANGELOG.md file. Ensure the changelog entry is clear, concise, and accurate. Focus on user-visible changes; avoid documenting purely internal refactors unless they have a direct impact. Maintain backward compatibility with the existing changelog structure. </constraints> <git> Commit the updated CHANGELOG.md file to the current branch. </git>
Why This Claude Code Prompt for “Write a Changelog” Works Better
When you type “Write a changelog for the new version of my app” into Claude Code, it lacks structure — Claude Code has to guess what format you want, how detailed to go, and what to prioritize. The optimized version removes that guesswork.
It starts with verification criteria (what 'done' looks like), describes the desired outcome rather than implementation steps, and scopes the task to specific files — matching Claude Code's agentic workflow.
