B3.1/5.0

Behavior2/5

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It confirms a read operation via 'List' but fails to specify what 'basic information' includes, whether pagination is supported, or any rate limiting concerns.

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?

Single sentence of 9 words is appropriately concise and front-loaded with the action verb. However, given the lack of annotations and output schema, the extreme brevity leaves significant gaps that additional context could have filled.

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?

While adequate for a zero-parameter tool, the description lacks sufficient detail given the absence of an output schema and annotations. It fails to clarify what constitutes 'basic information' or how this differs from the more detailed data returned by 'get_endpoint_schema'.

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?

The input schema contains 0 parameters, establishing a baseline of 4. The description does not need to compensate for missing parameter documentation, though it confirms the parameter-less nature by implying an unfiltered 'list all' operation.

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 uses a specific verb ('List') and clear resource ('registered APIs'), and specifies scope ('all' with 'basic information'). It implicitly distinguishes from 'search_endpoints' by suggesting unfiltered enumeration versus targeted search, though it doesn't explicitly clarify this distinction.

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 provided on when to use this versus siblings like 'search_endpoints' (for filtering) or 'get_endpoint_schema' (for detailed specification). No prerequisites or conditions mentioned.

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