getDocumentCategories

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

Annotations declare readOnlyHint=true, and the description's 'List' verb is consistent with that, so no contradiction. However, the description adds no behavioral context beyond what the annotation already provides—it doesn't mention that the format parameter controls serialization output (json vs xml), response structure, or any constraints.

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?

Three words with zero fluff and the key purpose front-loaded. It is appropriately brief for a simple list operation, though it borders on under-specification by being the entirety of the behavioral guidance.

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?

With no output schema, no pagination info, no description of what a 'document category' contains, and no explanation of how the format parameter alters the response, the definition is incomplete. The single sentence leaves an agent guessing about return values and format semantics.

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 0%, so the description carries the burden of explaining the format parameter but provides nothing. The only parameter, format (enum json/xml), is self-documenting via its enum values, but the description still fails to clarify how format affects the result or why it exists.

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 'List document categories' provides a clear verb ('List') and specific resource ('document categories'), distinguishing it from sibling category tools like getIssueCategories by the 'document' qualifier. It states what the tool does unambiguously, though it doesn't explicitly differentiate itself from similar category-listing siblings.

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?

No guidance is given on when this tool should be used versus alternatives. There are no usage conditions, prerequisites, or exclusions mentioned, and no sibling alternatives are referenced. An agent must infer usage entirely from the name.

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