Types

class DebugLoggingPlugin(outputPath: String = "adk_debug.yaml", includeSessionState: Boolean = true, includeSystemInstruction: Boolean = true, val name: String = "debug_logging_plugin") : Plugin

A plugin that captures complete debug information to a file.

GlobalInstructionPlugin

class GlobalInstructionPlugin : Plugin

Prepends an app-wide instruction (such as a common identity or set of rules) to the system instruction of every model request so all agents in the app share it. Mirrors Python ADK's GlobalInstructionPlugin.

LoggingPlugin

class LoggingPlugin(val name: String = "logging_plugin") : Plugin

A plugin that logs a high volume of requests and responses handled by the agent at each callback point.

Plugin

interface Plugin : AutoCloseable

Interface for creating plugins.

PluginManager

class PluginManager(val plugins: List<Plugin> = emptyList(), val skipClosingPlugins: Boolean = false) : AutoCloseable

Manages the pre-aggregation of typed functional callbacks.

ReflectAndRetryToolPlugin

class ReflectAndRetryToolPlugin(val maxRetries: Int = 3, val throwExceptionIfRetryExceeded: Boolean = true, val trackingScope: ReflectAndRetryToolPlugin.TrackingScope = TrackingScope.INVOCATION, val resultErrorExtractor: ReflectAndRetryToolPlugin.ResultErrorExtractor? = null, val retryPredicate: ReflectAndRetryToolPlugin.RetryPredicate? = null, val name: String = DEFAULT_NAME) : Plugin

Answers a failed tool call with guidance for the model to reflect on the error and retry, allowing up to maxRetries consecutive failures per tool.

SaveFilesAsArtifactsPlugin

class SaveFilesAsArtifactsPlugin @JvmOverloads constructor(attachFileReference: Boolean = true, val name: String = "save_files_as_artifacts_plugin") : Plugin

Saves files attached to user messages as artifacts, replacing each with a placeholder that names the artifact so agents can load it later, such as with LoadArtifactsTool. Each file is saved under its display name, where a user: prefix shares it across the user's sessions, or under a generated name if it has no display name; files over 20 MB are replaced with an error note instead. Mirrors Python ADK's SaveFilesAsArtifactsPlugin.
