open override fun call(input: String, context: ToolCallContext): Tool.Result

Canonical entry point for decorator logic. Override this method to add behavior while preserving context propagation to delegate.

requireType

inline fun <T : Any> Tool.requireType(message: String? = null): Tool

Wrap this tool to require a value of type T before execution (reified).

fun <T : Any> Tool.requireType(type: Class<T>, messageProvider: (String) -> String? = { null }): Tool

Wrap this tool to require a value of type T before execution.

toSpringToolCallback

fun Tool.toSpringToolCallback(): <Error class: unknown class>

Extension function to convert an Embabel Tool to a Spring AI ToolCallback.

toString

open override fun toString(): String

unwrapAs

inline fun <T : Tool> Tool.unwrapAs(): T?

Unwrap a tool to find a specific type, or return null if not found.

withAwaiting

fun Tool.withAwaiting(decider: AwaitDecider): Tool

Wrap this tool to conditionally await before execution.

withConfirmation

fun Tool.withConfirmation(messageProvider: (String) -> String): Tool

fun Tool.withConfirmation(message: String): Tool

Wrap this tool to always require confirmation before execution.

withDescription

open fun withDescription(newDescription: String): Tool

Create a new tool with a different description. Useful for providing context-specific descriptions while keeping the same functionality.

withEventPublication

fun Tool.withEventPublication(agentProcess: AgentProcess, action: Action?, llmOptions: <Error class: unknown class>): Tool

Extension function to wrap a Tool with event publication.

withName

open fun withName(newName: String): Tool

Create a new tool with a different name. Useful for namespacing tools when combining multiple tool sources.
