Valery focused on enhancing developer-facing documentation for the JetBrains/koog repository, updating guidance to reflect recent API changes around agent-to-tool conversions. By replacing references to AIAgent.asTool with AIAgentService.createAgentTool, Valery ensured that onboarding materials and technical instructions accurately matched the current codebase. The work, conducted entirely in Markdown and leveraging technical writing skills, aimed to reduce support friction and streamline the onboarding process for new users. Although the contribution was limited to a single feature over one month, the update provided clear, traceable documentation improvements, aligning user guidance with implementation and supporting maintainability for both developers and support teams.
