repository_object_search

Search for non-document repository objects by class and property filters. Returns object details with properties.

Instructions

PREREQUISITES IN ORDER: To use this tool, you MUST call two other tools first in a specific sequence.

  1. determine_class tool to get the class_name for search_class.

  2. get_searchable_property_descriptions to get a list of valid property_name for search_properties

Description: This tool retrieves repository objects other than Document instances.

:param search_parameters (SearchParameters): parameters for the searching including the object being searched for and any search conditions.

:returns: A the repository object details, including: - repositoryObjects (dict): a dictionary containing independentObjects: - independentObjects (list): A list of independent objects, each containing: - properties (list): A list of properties, each containing: - label (str): The name of the property. - value (str): The value of the property.

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must convey behavioral traits. It states the tool retrieves objects, implying a read operation. However, it does not mention permissions, idempotency, or what happens if prerequisites are not met.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is somewhat verbose and repetitive, with redundant sections ('PREREQUISITES IN ORDER' and then the description). It could be streamlined by integrating prerequisites and the main description more concisely.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity (nested objects, multiple siblings, no annotations), the description covers purpose, prerequisites, and return structure. It lacks examples but is otherwise adequate for a search tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents parameters well. The description adds the return structure (independentObjects, properties) and clarifies AND logic for search_properties, adding value beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool retrieves repository objects other than Document instances, distinguishing it from document_search. It also lists detailed prerequisites that define its purpose.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly requires calling determine_class and get_searchable_property_descriptions first, providing clear workflow guidance. It implies this tool is for non-Document objects, but does not explicitly state when not to use it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
