Tool

relationalai.agent.cortex.tool

Abstract base class for RAI-powered tools that can be used by Cortex agents.

A Tool provides semantic data exploration capabilities through a consistent interface:

• Discovery: What models and concepts are available?
• Verbalization: Detailed model structure and relationships
• Explanation: Business rules and semantics for specific concepts
• Querying: Execute structured queries against the data model

Implement this interface to create custom tools, or use DefaultTool for standard RAI model-based tools.

Methods

.description()

Tool.description() -> str

Return a human-readable description of this tool’s purpose.

Returns:

• str - A description of the tool.

.concepts()

Tool.concepts() -> List[str]

Return list of key concept names available in this tool’s domain.

Returns:

• list of str - Concept names available in this tool.

.verbalize()

Tool.verbalize() -> str

Return detailed structure and relationships for the entire model.

Returns:

• str - A natural language description of the model structure.

.explain()

Tool.explain(concept: str) -> str

Return detailed explanation of business rules for a specific concept.

Parameters:

• concept

  (str) - The name of the concept to explain.

Returns:

• str - A natural language explanation of the concept.

.queries()

Tool.queries() -> QueriesMeta

Return a typed view of the available pre-defined queries.

Returns:

• QueriesMeta - Typed view exposing QueriesMeta.mode, QueriesMeta.catalog_entries, and the raw underlying dict. When no Queries provider is configured, mode is None and QueriesMeta.message carries a human-readable note.

.query()

Tool.query(params: dict) -> Union[rai.Fragment, pandas.DataFrame]

Execute a query against this tool’s model and return results.

Parameters:

• params

  (dict) - Query parameters including "id" (query identifier) and "args" (query arguments).

Returns:

• relationalai.semantics.Fragment or pandas.DataFrame - Query results.

Raises:

• ValueError - If queries capability is not configured.
• KeyError - If query ID is not found.
