Create Knowledge Category

create_kb_category

Create a new category in a knowledge base by providing a label and knowledge base sys_id. Optionally assign a parent category to create subcategories.

Instructions

Create a new category in a knowledge base. Requires a label and the knowledge base sys_id. Optionally set a parent category for subcategories.

IMPORTANT: This creates a new category on the instance.

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.
labelYesThe display label for the new category.
knowledge_base_sys_idYesThe sys_id of the knowledge base to create the category in.
parent_categoryNoOptional parent category sys_id for creating subcategories.
activeNoWhether the category is active (default true).
Behavior2/5

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

No annotations are provided, so the description must disclose behaviors. It only states 'This creates a new category on the instance,' which is obvious. It does not discuss permissions, side effects, rate limits, or failure states.

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

Conciseness4/5

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

The description is concise, with two short sentences covering purpose and a single sentence warning. It is front-loaded with the most important information.

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

Completeness2/5

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

Despite having 5 parameters and no output schema, the description does not mention return values or error handling. For a creation tool, this leaves the agent uncertain about what to expect.

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 descriptions for all parameters. The description reiterates the required parameters and adds optional parent context, but does not provide meaning 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 verb 'Create' and the resource 'a new category in a knowledge base'. It distinguishes from sibling tools like create_kb_article by specifying the resource type.

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

Usage Guidelines3/5

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

The description mentions required parameters and optional parent, which implies when to use, but it does not provide guidance on when not to use this tool or how it compares to alternatives like list_kb_categories or update_kb_category.

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