🤖 Agent 接口 ¶

CustomizeAgent provides a flexible framework for creating specialized LLM-powered agents without writing custom code. It enables the creation of agents with well-defined inputs and outputs, custom prompt templates, and configurable parsing strategies.

Attributes:

Name	Type	Description
`name`	`str`	The name of the agent.
`description`	`str`	A description of the agent's purpose and capabilities.
`prompt`	`str`	The prompt template that will be used for the agent's primary action. Should contain placeholders in the format `{input_name}` for each input parameter.
`llm_config`	`LLMConfig`	Configuration for the language model.
`inputs`	`List[dict]`	List of input specifications, where each dict (e.g., `{"name": str, "type": str, "description": str, ["required": bool]}`) contains: - name (str): Name of the input parameter - type (str): Type of the input - description (str): Description of what the input represents - required (bool, optional): Whether this input is required (default: True)
`outputs`	`List[dict]`	List of output specifications, where each dict (e.g., `{"name": str, "type": str, "description": str, ["required": bool]}`) contains: - name (str): Name of the output field - type (str): Type of the output - description (str): Description of what the output represents - required (bool, optional): Whether this output is required (default: True)
`system_prompt`	`str`	The system prompt for the LLM. Defaults to DEFAULT_SYSTEM_PROMPT.
`output_parser`	`Type[ActionOutput]`	A custom class for parsing the LLM's output. Must be a subclass of ActionOutput.
`parse_mode`	`str`	Mode for parsing LLM output. Options are: - "title": Parse outputs using section titles (default) - "str": Parse as plain text - "json": Parse as JSON - "xml": Parse as XML - "custom": Use a custom parsing function
`parse_func`	`Callable`	Custom function for parsing LLM output when parse_mode is "custom". Must accept a "content" parameter and return a dictionary.
`title_format`	`str`	Format string for title parsing mode with {title} placeholder. Default is "## {title}".
