Behavior2/5

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

No annotations are provided, so the description carries full burden for behavioral traits. It does not disclose that the tool is read-only, nor does it explain pagination behavior (cursor, limit) or that it returns a list of tagged elements from different entity types. The description is too brief to inform an agent about side effects or response characteristics.

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 a single, short sentence (5 words) with no unnecessary words. It is front-loaded and efficient. However, it could be slightly expanded to cover essential usage context without becoming verbose.

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?

Given the tool's complexity (5 parameters, including enums and pagination cursor) and lack of annotations or output schema, the description is incomplete. An agent would not know how to construct a proper query, what results to expect, or how to handle pagination. The description fails to provide enough context for accurate invocation.

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 description coverage is 100% – each parameter (slug, limit, direction, cursor, entityType) has a brief description. The tool description adds no additional semantic meaning beyond what the schema already provides, so it meets the baseline but does not elevate the score.

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?

Description 'Get elements by tag' clearly indicates a verb+resource pattern, and the tool's name and schema suggest it retrieves typed elements (api, collection, workspace) associated with a tag. It distinguishes from sibling tools like get_api_tags which get tags for an API instead. However, 'elements' is somewhat vague without reading the schema.

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 guidance on when to use this tool versus alternatives such as list_apis or get_collection. The description does not mention when to filter by entityType or how pagination works. No exclusions or sibling tool references are provided.

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