Kotlin DSL - type-safe builders, Gradle DSL, @DslMarker
Build type-safe DSLs using Kotlin's @DslMarker, type-safe builders, and Gradle DSL patterns. Use this when creating configuration builders, Gradle convention plugins, or domain-specific languages that need proper scope control and compile-time safety.

@ConfigDsl
class ServerConfig private constructor(val host: String, val port: Int) {
class Builder {
var host = "localhost"
var port = 8080
fun build() = ServerConfig(host, port)
}
}
fun serverConfig(block: ServerConfig.Builder.() -> Unit) =
ServerConfig.Builder().apply(block).build()
// Usage
val config = serverConfig { host = "api.example.com"; port = 443 }
| Issue | Resolution |
|---|---|
| Scope pollution | Add @DslMarker annotation |
| Gradle cache stale | Run ./gradlew --stop |
Skill("kotlin-dsl")
This skill should be used when the user asks to "create a slash command", "add a command", "write a custom command", "define command arguments", "use command frontmatter", "organize commands", "create command with file references", "interactive command", "use AskUserQuestion in command", or needs guidance on slash command structure, YAML frontmatter fields, dynamic arguments, bash execution in commands, user interaction patterns, or command development best practices for Claude Code.
This skill should be used when the user asks to "create an agent", "add an agent", "write a subagent", "agent frontmatter", "when to use description", "agent examples", "agent tools", "agent colors", "autonomous agent", or needs guidance on agent structure, system prompts, triggering conditions, or agent development best practices for Claude Code plugins.
This skill should be used when the user asks to "create a hook", "add a PreToolUse/PostToolUse/Stop hook", "validate tool use", "implement prompt-based hooks", "use ${CLAUDE_PLUGIN_ROOT}", "set up event-driven automation", "block dangerous commands", or mentions hook events (PreToolUse, PostToolUse, Stop, SubagentStop, SessionStart, SessionEnd, UserPromptSubmit, PreCompact, Notification). Provides comprehensive guidance for creating and implementing Claude Code plugin hooks with focus on advanced prompt-based hooks API.
