AbstractBot.

This class is an abstract representation a base abstraction for all Chatbots. Inherits from ToolInterface for tool management and VectorInterface for vector store operations.

Initialize the Chatbot with the given configuration.

PARAMETER	DESCRIPTION

block_on_threat	Block responses on detected threats. TYPE: bool DEFAULT: False
injection_detection	Run the prompt-injection detector on user input. Default True. Set False on bots whose inputs are short imperative commands the detector tends to misclassify. TYPE: bool DEFAULT: True

Bind a RequestContext to the current asyncio task for the block's lifetime.

Replaces the removed retrieval() method. Absorbs PBAC enforcement and concurrency limiting. Anything awaited beneath this block can call current_context() and get the same RequestContext object without explicit parameter threading.

Delegates access control entirely to the PDP evaluator (PBAC). When no PDP is configured (e.g. during development or when policies/ dir is absent), this method is fail-open and allows all requests.

Superuser bypass is handled by policies/defaults.yaml:allow_superuser_all at priority=100 — no hardcoded superuser check here.

clone_for_user async

clone_for_user(user_context: 'UserContext') -> 'AbstractBot'

Return an independent agent instance scoped to a single user.

Used by integration wrappers when singleton_agent is disabled so each user gets a fully isolated agent (no shared mutable state, no swap-and-restore dance around the shared ToolManager). This is heavier than cloning only the ToolManager but removes the need for a cross-user lock and supports tools that keep state on self.

The default implementation raises NotImplementedError because reconstructing an agent faithfully requires knowledge its base class does not have (LLM config, vector store, memory backend, system prompt, toolkits). Subclasses that want per-user agent isolation must implement this method — typically by calling self.__class__(**self._init_kwargs) if they captured their construction kwargs, or by delegating to a factory registered with the BotManager.

PARAMETER	DESCRIPTION
user_context	Channel-agnostic identity snapshot. TYPE: 'UserContext'

'AbstractBot'	invoking await new_agent.post_login(user_context) once

Generate a structured infographic response.

Uses a template to instruct the LLM to return an InfographicResponse with typed blocks (title, hero_card, chart, summary, etc.).

Content negotiation is controlled by the accept parameter: - "text/html" (default): renders a self-contained HTML document with inline CSS and ECharts JS — backward compatible. - "application/json": returns the raw InfographicResponse JSON.

PARAMETER	DESCRIPTION
question	The topic, query, or data description for the infographic. TYPE: str
template	Template name from the registry (e.g., 'basic', 'executive', 'dashboard', 'comparison', 'timeline', 'minimal'). Pass None to let the LLM decide the block structure freely. TYPE: Optional[str] DEFAULT: None
session_id	Session identifier for conversation history. TYPE: Optional[str] DEFAULT: None
user_id	User identifier. TYPE: Optional[str] DEFAULT: None
use_vector_context	Whether to retrieve context from vector store. TYPE: bool DEFAULT: True
use_conversation_history	Whether to use conversation history. TYPE: bool DEFAULT: False
theme	Color theme hint ('light', 'dark', 'corporate', 'vibrant'). TYPE: Optional[str] DEFAULT: None
accept	Content type for the response. Defaults to "text/html" for backward compatibility. TYPE: str DEFAULT: 'text/html'
ctx	Request context. TYPE: Optional[RequestContext] DEFAULT: None
**kwargs	Additional arguments passed to ask(). DEFAULT: {}

RETURNS	DESCRIPTION
AIMessage	AIMessage with structured_output containing InfographicResponse.
AIMessage	When accept is "text/html", response.content contains
AIMessage	the rendered HTML and response.output_mode is OutputMode.HTML.

RAISES	DESCRIPTION
KeyError	If the template name is not found in the registry.

enhance_infographic(*, skeleton: str, brief: str, data_context: 'Dict[str, Any]', js_bundles_available: 'List[Any]') -> str

Enhance a deterministic infographic skeleton with LLM-generated JS.

The LLM is instructed to add interactivity using only the bundles in js_bundles_available. The returned HTML is validated by the toolkit's validate_enhanced_html helper before being persisted.

PARAMETER	DESCRIPTION
skeleton	Complete HTML document from the deterministic render pass. TYPE: str
brief	Short description of the desired interactive enhancement. TYPE: str
data_context	JSON-serialisable dict of DataFrames (as records). TYPE: 'Dict[str, Any]'

RETURNS	DESCRIPTION
str	Enhanced HTML string. The caller is responsible for validation.

RAISES	DESCRIPTION
Exception	Any LLM completion error is propagated to the caller.

Note

This method is intentionally simple — it is the caller's responsibility to validate the returned HTML and fall back to the skeleton on InfographicValidationError(code='ENHANCE_OUTPUT_INVALID').

Bases: AbstractBot

Base Bot implementation providing concrete implementations of abstract methods defined in AbstractBot.

This is the recommended base class for creating custom bots. It provides full implementations of ask, ask_stream, invoke, and conversation methods with support for: - Vector store context retrieval - Knowledge base integration - Conversation history management - Tool usage (agentic mode) - Multiple output formats - Security and prompt injection detection

Subclasses can override these methods to customize behavior or use them as-is for standard bot functionality.

        block_on_threat (bool): Block responses on detected threats.
        injection_detection (bool): Run the prompt-injection detector on
            user input. Default True. Set False on bots whose inputs are
            short imperative commands the detector tends to misclassify.

Chatbot

Chatbot(name: str = 'Nav', system_prompt: str = None, human_prompt: str = None, from_database: bool = True, tools: List[Union[str, AbstractTool]] = None, **kwargs)

Bases: BaseBot

Represents an Bot (Chatbot, Agent) in Navigator.

This class is the base for all chatbots and agents in the ai-parrot framework.

This class can be used in two ways

1. Manual creation: bot = Chatbot(name="MyBot", tools=[...])
2. Database loading: bot = Chatbot(name="MyBot", from_database=True)

Initialize the Chatbot with manual creation or database loading support.

PARAMETER	DESCRIPTION
name	Bot name TYPE: str DEFAULT: 'Nav'
system_prompt	Custom system prompt TYPE: str DEFAULT: None
human_prompt	Custom human prompt TYPE: str DEFAULT: None
from_database	Whether to load configuration from database TYPE: bool DEFAULT: True
tools	List of tools for manual creation TYPE: List[Union[str, AbstractTool]] DEFAULT: None
**kwargs	Additional configuration DEFAULT: {}

Bases: Chatbot, NotificationMixin

Represents an Agent in Navigator.

Agents are chatbots that can access to Tools and execute commands. Each Agent has a name, a role, a goal, a backstory, and an optional language model (llm).

These agents are designed to interact with structured and unstructured data sources.

Features: - Built-in MCP server support (no separate mixin needed) - Can connect to HTTP, OAuth, API-key authenticated, and local MCP servers - Automatic tool registration from MCP servers - Compatible with all existing agent functionality - Notification capabilities through various channels (e.g., email, Slack, Teams)

Bases: BasicAgent

An agent specialized in performing web searches.

By default, it is equipped with several search tools: - GoogleSearchTool - GoogleSiteSearchTool - DdgSearchTool - BingSearchTool - SerpApiSearchTool

If use_builtin_search is True, it will fallback to using Gemini's built-in Google Search functionality via tool_type='builtin_tools'.

If contrastive_search is True, performs a two-step search: first the original query, then a contrastive analysis of competitors/alternatives based on the initial results.

If synthesize is True, an additional LLM call (with use_tools=False) analyzes and synthesizes the search results using a synthesis prompt.

Initialize the WebSearchAgent.
