Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install kotlin-nullable-types-safe-calls

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent applies Kotlin's nullability system: nullable types, safe calls, the Elvis operator, smart casts, not-null assertions and platform types, then designs null-safe APIs. You get code where the absence of a value is explicit.
