C2.9/5.0

Behavior2/5

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

The annotations already declare readOnlyHint=true and destructiveHint=false, so the prominent safety profile is covered. However, the description itself exposes no behaviors beyond those, such as whether system-generated fields are included, how pagination works with pageToken, or any default-capacity implications. No contradiction, but the description adds minimal behavioral value beyond the annotations.

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 clean sentence with no filler or repetition; it is fully front-loaded with the core verb and resource. Even though the tool is complex at the schema level, the description itself is not verbose, and every word earns its place in the sentence.

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

Completeness3/5

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

With an output schema present, return values need not be explained in the description. However, the domain of 'fields' is never clarified (entity fields? datatable fields? custom fields?), and the dense filter schema with enums and nested properties calls for more orientation. The presence of no required parameters allows an empty invocation, but a user needing to filter correctly would have to reverse-engineer the schema.

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

Parameters2/5

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

Schema description coverage is 0% in the description text. The phrase 'with filtering and pagination' crudely maps to the 'filter', 'pageSize', and 'pageToken' parameters, but the nested filter object is highly complex with enums for types, valueModes, visibilities, and an includeOptions flag. The description does not compensate for the schema's lack of parameter-level explanations.

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

Purpose4/5

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

The description states a clear verb-resource operation ('List fields') and explicitly mentions filtering and pagination. It is distinguishable from direct siblings like field_get_field and field_get_list_field_options by resource granularity, though the term 'fields' alone is generic and could be ambiguous; explicit sibling differentiation is not provided.

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?

There is no guidance on when to use this tool versus alternatives such as field_get_field for fetching a single field or field_get_list_field_options for options belonging to a field. The description implies its own purpose but never states selection criteria, exclusions, or preconditions relative to other field-related tools.

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