Function injectSessionState

Injects session state values into an instruction template.

This method is intended to be used in InstructionProvider based instruction and global_instruction which are called with readonly_context.

Example:

import { injectSessionState } from './utils/instructions-utils';

async function buildInstruction(readonlyContext: ReadonlyContext): Promise<string> {
  return await injectSessionState(
    'You can inject a state variable like {var_name} or an artifact ' +
    '{artifact.file_name} into the instruction template.',
    readonlyContext
  );
}

const agent = new LlmAgent({
  model: "gemini-2.0-flash",
  name: "agent",
  instruction: buildInstruction,
});
