Get Catalog Category Details

get_catalog_category

Retrieve details of a service catalog category using its sys_id, including the count of items within that category.

Instructions

Get details of a specific service catalog category by sys_id, including the count of items in that category.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
instanceNoThe ServiceNow instance auth alias to use. This is the alias configured via `now-sdk auth --add` (e.g., "myinstance", "prod", "test"). The user will typically refer to this by name when saying things like "on my myinstance instance". If not provided, falls back to the SN_AUTH_ALIAS environment variable.
sys_idYesThe sys_id of the catalog category.
Behavior2/5

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

No annotations are provided, so the description must fully disclose behavioral traits. It mentions the count inclusion but does not specify read-only nature, authentication requirements, rate limits, or error behavior (e.g., handling of invalid sys_id).

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

Conciseness5/5

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

Single sentence, front-loaded with the key action and resource. No redundant words.

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?

For a simple get-by-id tool with two parameters, the description is mostly adequate. It mentions the count inclusion. However, it omits return format and error handling details. Nonetheless, the simplicity reduces the need for extensive completeness.

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

Parameters3/5

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

Schema coverage is 100% with well-described parameters. The description adds context about including item count but does not enhance understanding beyond the schema. Baseline score of 3 applies.

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 verb 'Get details', the specific resource 'service catalog category', and the unique addition of 'including the count of items'. This distinguishes it from sibling tools like list_catalog_categories.

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

Usage Guidelines2/5

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

No explicit guidance on when to use this tool versus alternatives such as list_catalog_categories or get_catalog_item. The description does not mention context, prerequisites, or when-not scenarios.

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