Worked on enhancing the elastic/ingest-docs repository by documenting a known issue affecting ECS fields in {agent} integrations across the 8.13.x release series. Focused on providing clear, actionable guidance for developers and customer-support teams, the work involved authoring detailed asciidoc documentation that outlined the impact of changes in the ecs@mappings component template. The documentation included upgrade recommendations to 8.14.0 and practical workarounds for environments unable to upgrade immediately. This effort prioritized reducing customer disruption and improving onboarding by expanding the knowledge base, leveraging skills in technical writing and documentation to address real-world upgrade and compatibility challenges.
