AI agent skills for Kotlin

A collection of AI agent skills useful for projects using the Kotlin language. Skills are following the Agent Skills standard, see agentskills.io for more information.

How do Skills work?

In practice, skills are self-contained folders that package instructions, scripts, and resources together for an AI agent to use on a specific use case. Each folder includes a SKILL.md file with YAML frontmatter (name and description) followed by the guidance your coding agent follows while the skill is active.

Skill naming conventions

All skills in the repository should follow the following naming convention: kotlin-<category>-<functional-name>.

<category> here is one of predefined categories. Current categories are:

backend - server-side development skills, such as correct use of Spring, JPA, and other backend frameworks with Kotlin
tooling - any tooling related skills, for example build tooling one

Please open an issue to add additional categories.

<functional-name> should be a short, descriptive name of the skill, using kebab-case naming convention.
