Narumi Mitchell enhanced the security incidents documentation in the 18F/handbook repository, focusing on improving clarity and maintainability for incident response processes. She updated the Markdown-based security-incidents.md file by removing a redundant link, streamlining the content for easier onboarding and consistent security practices. To optimize documentation workflows, Narumi leveraged content management and documentation skills to add 'TTS's' to the cSpell ignore list, reducing false positives during spell checks and lowering review overhead. The work addressed targeted improvements rather than broad changes, reflecting a focused approach to documentation quality and maintainability within the scope of a single feature update.
