Kotlin AI skills
Kotlin AI skills are reusable instructions that help AI agents perform Kotlin-specific tasks more reliably.
A skill gives an AI agent the context it needs before it starts executing a task. For example, a skill can point to a relevant API, define prerequisites, or provide step-by-step workflow guidance.
Kotlin AI skills help agents produce more accurate results and reduce the time you spend explaining the task yourself. For teams, skills also provide a shared framework for common tasks, so everyone gets consistent results.
Kotlin AI skills follow the Agent Skills standard, so you can use them with compatible AI agents, for example, Junie, Claude Code, OpenAI Codex, Google Gemini, and GitHub Copilot.
