KernelFunctionFromPrompt(function_name: str, plugin_name: str | None = None, description: str | None = None, prompt: str | None = None, template_format: Literal['semantic-kernel', 'handlebars', 'jinja2'] = 'semantic-kernel', prompt_template: PromptTemplateBase | None = None, prompt_template_config: PromptTemplateConfig | None = None, prompt_execution_settings: PromptExecutionSettings | Sequence[PromptExecutionSettings] | Mapping[str, PromptExecutionSettings] | None = None)

Parameters

Name	Description
function_name Required	str The name of the function
plugin_name	str The name of the plugin Default value: None
description	str The description for the function Default value: None
prompt	<xref:Optional>[str] The prompt Default value: None
template_format	<xref:Optional>[str] The template format, default is "semantic-kernel" Default value: semantic-kernel
prompt_template	<xref:Optional>[<xref:KernelPromptTemplate>] The prompt template Default value: None
prompt_template_config	<xref:Optional>[<xref:PromptTemplateConfig>] The prompt template configuration Default value: None
prompt_execution_settings	Optional instance, list or dict of PromptExecutionSettings to be used by the function, can also be supplied through prompt_template_config, but the supplied one is used if both are present. prompt_template_config (Optional[PromptTemplateConfig]): the prompt template config. Default value: None

Methods

from_directory	Creates a new instance of the KernelFunctionFromPrompt class from a directory. The directory needs to contain: A prompt file named skprompt.txt A config file named config.json
from_yaml	Creates a new instance of the KernelFunctionFromPrompt class from a YAML string.
rewrite_execution_settings	Rewrite execution settings to a dictionary. If the prompt_execution_settings is not a dictionary, it is converted to a dictionary. If it is not supplied, but prompt_template is, the prompt_template's execution settings are used.
update_arguments_with_defaults	Update any missing values with their defaults.

from_directory
