    • canonicalInstruction

      public io.reactivex.rxjava3.core.Single<Map.Entry<String,Boolean>> canonicalInstruction(ReadonlyContext context)
      Constructs the text instruction for this agent based on the instruction field. Also returns a boolean indicating that state injection should be bypassed when the instruction is constructed with an Instruction.Provider.

      This method is only for use by Agent Development Kit.

      Parameters:
      context - The context to retrieve the session state.
      Returns:
      The resolved instruction as a Single wrapped Map.Entry. The key is the instruction string and the value is a boolean indicating if state injection should be bypassed.

    • canonicalGlobalInstruction

      public io.reactivex.rxjava3.core.Single<Map.Entry<String,Boolean>> canonicalGlobalInstruction(ReadonlyContext context)
      Constructs the text global instruction for this agent based on the globalInstruction field. Also returns a boolean indicating that state injection should be bypassed when the instruction is constructed with an Instruction.Provider.

      This method is only for use by Agent Development Kit.

      Parameters:
      context - The context to retrieve the session state.
      Returns:
      The resolved global instruction as a Single wrapped Map.Entry. The key is the instruction string and the value is a boolean indicating if state injection should be bypassed.

    • canonicalTools

      public io.reactivex.rxjava3.core.Flowable<BaseTool> canonicalTools(Optional<ReadonlyContext> context)
      Constructs the list of tools for this agent based on the tools() field.

      This method is only for use by Agent Development Kit.

      Parameters:
      context - The context to retrieve the session state.
      Returns:
      The resolved list of tools as a Single wrapped list of BaseTool.

    • canonicalTools

      public io.reactivex.rxjava3.core.Flowable<BaseTool> canonicalTools()
      Overload of canonicalTools that defaults to an empty context.

    • canonicalTools

      public io.reactivex.rxjava3.core.Flowable<BaseTool> canonicalTools(ReadonlyContext context)
      Convenience overload of canonicalTools that accepts a non-optional ReadonlyContext.
