GlobalInstructionPlugin
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.
val company = GlobalInstructionPlugin("You work for Acme.")
val rules = GlobalInstructionPlugin({ context -> loadRules(context.userId) }, name = "rules")
InMemoryRunner(agent = agent, plugins = listOf(company, rules))Constructors
Creates a plugin that applies globalInstruction, filling in session state placeholders such as {user_name} for each request, as an agent's text instruction does. An instruction that resolves to an empty string leaves the request unchanged. If a placeholder names a missing state variable, beforeModel throws IllegalArgumentException unless the placeholder is marked optional, as in {nickname?}.
Creates a plugin that applies the instruction instructionProvider returns for each request, with no placeholders filled in. A null or empty instruction leaves the request unchanged.
