Bots

Bot and Agent implementations.

Only the base hierarchy is imported eagerly — AbstractBot, BaseBot, BasicAgent and Agent — so import parrot.bots stays cheap and never drags optional satellites (ai-parrot-server, ai-parrot-tools, google-genai…) into the process. Every concrete bot class is still reachable as from parrot.bots import X but is resolved lazily on first access.

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
name	Name of the bot. TYPE: str DEFAULT: 'Nav'

status property writable

status: AgentStatus

Get the current status of the agent.

system_prompt property writable

system_prompt: str

Get Current System Prompt Template.

prompt_builder property writable

prompt_builder: Optional[PromptBuilder]

Get the composable prompt builder, if set.

is_configured property

is_configured: bool

Return whether the bot has completed its configuration.

context_budget property

context_budget: Optional[ContextBudget]

The bot's per-turn compaction budget, or None when compaction is disabled.

Resolution (FEAT-525, spec G3/C3):

• context_budget=False (constructor kwarg) or the PARROT_COMPACTION_DISABLED=1 environment kill switch ⇒ None — every render/save goes through FEAT-524's plain path, byte for byte.
• An explicit :class:ContextBudget instance ⇒ used as given, except its max_turns is overridden by self.max_context_turns when that is set.
• None/True (the default) ⇒ auto-built from :func:~parrot.memory.compaction.budget.build_default_budget using self._llm_model, with max_turns=self.max_context_turns. When the model is unknown (falls back to the 32k window), this is logged once per bot at INFO — not once per call.

RETURNS	DESCRIPTION
Optional[ContextBudget]	The resolved budget, or None when compaction is disabled.

memory_key_id property

memory_key_id: str

Stable per-agent segment of the conversation storage key (FEAT-524).

Every conversation history is keyed by (chatbot, user, session), and the same value is stamped onto ConversationTurn.chatbot_id so attribution and storage location always agree.

The value is the explicit chatbot_id when one was supplied (as a constructor kwarg, or loaded from the database by Chatbot), and self.name otherwise. It is deliberately not the auto-generated self.chatbot_id: that default is a fresh uuid4().hex per process, so keying by it would silently start a new history on every restart for any bot that never declared an id — scripts, tools, tests and most ad-hoc BaseBot instances.

Consequence accepted for v1 (spec §7): two different bots created without a chatbot_id but with the same name share a history. That is strictly better than today, where they share the completely un-segmented key.

RETURNS	DESCRIPTION
str	The key segment, never empty.

Persist one conversation turn — the single writer (FEAT-524, FEAT-525).

Every bot entry point routes its turn through here. The turn is always stored under self.memory_key_id; the chatbot_id parameter this method used to accept was removed on purpose, so no caller can write into a different agent's history by accident.

PARAMETER	DESCRIPTION
user_id	Owner of the conversation. TYPE: str
session_id	Conversation session. TYPE: str
turn	The turn to persist. Its chatbot_id MUST equal self.memory_key_id — attribution and storage key are two views of the same fact and must not disagree. TYPE: ConversationTurn
compaction	This round's :class:CompactionCommit (FEAT-525), built via :meth:build_compaction_commit. When given, the memory folds it into metadata["compaction"] (calibration EWMA, boundary, stage2_needed) in the same write as the turn. None for writers that do not participate in the budget round-trip (e.g. an ask_stream partial save on error). TYPE: Optional[CompactionCommit] DEFAULT: None

RAISES	DESCRIPTION
ValueError	If turn.chatbot_id does not match self.memory_key_id.

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

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

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]'
js_bundles_available	List of JSBundle instances the LLM may reference. TYPE: 'List[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.

            user input. Default True. Set False on bots whose inputs are
            short imperative commands the detector tends to misclassify.
        injection_probability_threshold (float): Minimum pytector
            probability (0.0-1.0) required to treat input as an injection.

            prompt layers. When set, uses PromptBuilder instead of legacy
            system_prompt_template. Default is None (legacy behavior).
        event_bus: Optional ``EventBus`` instance for dual-emit lifecycle
            subscribers.  When ``None`` (default), the per-bot registry
            forwards to the global registry only.

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)
