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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the read-only behavior is established. The description adds useful context by noting the resources are 'public' and enumerating categories, but it does not disclose return format, pagination, or any other behavioral detail. Given annotation coverage, a 3 is appropriate.

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

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

The description is a single, front-loaded sentence with no filler. Every part contributes meaning, naming the resource type and its categories without unnecessary elaboration.

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

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

For a simple list tool with one optional parameter and read-only annotations, the description is mostly sufficient. However, it does not clarify what counts as a 'resource,' how results are returned, or how this differs from the sibling overview tool, leaving an agent to fill in those gaps.

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

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

Schema description coverage is 100%, and the category parameter already has a clear enum and description. The description lists several categories but also mentions 'discovery,' which is not present in the schema enum, creating slight ambiguity. With the schema carrying the parameter meaning, a baseline 3 is fair.

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

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

The description clearly states a specific action ('List') and a specific resource ('Genvernium's public developer, auth, pricing, and discovery resources'), making the tool's purpose understandable. It does not explicitly contrast itself with the sibling get_public_documentation_overview, so it loses a point on differentiation.

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

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

The description gives no guidance on when to use this tool versus get_public_documentation_overview, nor does it state any exclusions or prerequisites. The category filter is mentioned only indirectly through the resource list, so an agent must infer the intended use case.

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