PROFILE
Marko Marinkovic
Worked extensively on the JetBrains/koog repository, delivering a series of documentation-driven features that improved onboarding, integration, and maintainability for AI agent systems. Focused on clarifying agent communication protocols, LLM parameter configuration, and multi-provider support, the work included comprehensive guides, code samples, and automated documentation tooling. Leveraged Kotlin, Java, and Python scripting to implement dynamic API reference linking and ensure documentation accuracy through verification scripts. Emphasized clear technical writing and protocol specification, enabling faster adoption and reducing support overhead. The approach prioritized traceability, version-controlled updates, and cross-language integration, resulting in a robust knowledge base for developers working with AI agents.

Jan 1, 2026In January 2026, delivered enhanced Planner Agents documentation for JetBrains/koog, clarifying functionality, usage, iterative planning cycles, and introducing simple LLM-based planner examples. The work focused on improving developer onboarding, reducing integration ambiguity, and accelerating adoption of Planner agents in projects. Key contribution is post-review modifications to Planner agent docs (commit b7ddf1a48b0083937f237e40ce5a91d1871112d2) (#1301). While no major bugs were fixed this month, documentation improvements directly support reliable usage and faster issue resolution in production by clarifying expectations and workflows. Overall, the effort strengthens the team's ability to plan iteratively with LLMs, improving developer velocity and reducing support load. Technologies demonstrated include documentation best practices, version-controlled docs, and clear examples for LLM-based planning.
