Tool Parameter Normalizer

Software componentTools & IntegrationOrchestration & Toolsarc:ToolParameterNormalizer

A pre-invocation component that maps user or domain terminology variants extracted from requests to canonical tool parameter values before the tool call is executed.

Responsibility. Normalises extracted argument values to the canonical vocabulary a tool expects.

Also known as: Entity Normalizer, Parameter normalization, Entity canonicalization

Design guidance

SHOULD normalize common aliases to canonical parameter formats before tool invocation, as an alternative or complement to prompting the agent to convert them.

Quantitative guidance

As stated by the sources; verify before use.

Schema enrichment, normalisation and validation cut parameter errors 28->8 (71%) and raised task success 82%->89% (Ch3.4).

Classification

Patterns: Canonical value mapping
Quality attributes: Functional suitability: correctness and validity (ISO/IEC 25010 | NIST AI RMF: valid)Reliability (ISO/IEC 25010 | NIST AI RMF: valid and reliable)
Risks mitigated: Parameter errors from lexical variation (e.g., 'third quarter top-line expansion')Parameter format violations causing tool validation failures
