List custom field definitions

list_custom_fields

Retrieve all custom field definitions for your Karbon tenant, including names, types, list options, and applicable entities.

Instructions

List all custom field definitions for the Karbon tenant — field names, types (Text, Number, Date, Boolean, Colleague, ListSingleSelect, ListMultipleSelect), list options, and which entities they apply to.

TDQS

A4/5.0
Behavior4/5

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

With no annotations, the description carries the full burden. It transparently describes the output content (field names, types, list options, applicable entities) and implies a read-only, non-destructive operation. No contradictions or hidden behaviors are present.

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?

The description is a single, well-structured sentence that front-loads the main purpose and lists key output details. No redundant or extraneous information.

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 low complexity (0 params, no output schema, no annotations), the description provides sufficient detail about the return content. It could note potential pagination or ordering, but that is not critical for this simple list 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?

There are zero parameters and schema coverage is 100%. The description adds meaning by detailing what the output includes, which is beyond the empty schema. Baseline for 0 params is 4, and this is met.

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 explicitly states 'List all custom field definitions for the Karbon tenant' and enumerates the included fields, types, list options, and applicable entities. It clearly distinguishes from sibling tools like create_custom_field or delete_custom_field.

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?

The description does not provide any guidance on when to use this tool versus alternatives such as get_custom_field_values or set_custom_field_values. No when-not-to-use or contextual usage hints are given.

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