iulaan_categories

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

No annotations are provided, so the description carries the burden of behavioral disclosure. 'List' implies a read-only operation, but the description does not detail any pagination, sorting, or error behavior. For a simple listing tool, this minimal transparency is adequate but not rich.

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, short sentence that fully states the tool's purpose. No wasted words, and the content is appropriately sized for a simple parameterless list operation.

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?

Given the tool's simplicity (no parameters, no output schema, no annotations), the description is sufficient to tell an agent what it does. It does not describe the return value format, but that may be inferred from the word 'categories' and sibling tool patterns. Complete enough for its low complexity.

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?

The tool has zero parameters, so the schema is trivially covered (100%). The description does not need to add parameter semantics, and the baseline of 4 for zero-param tools applies. No missing information here.

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 Iulaan categories.' uses a specific verb ('List') and a specific resource ('Iulaan categories'), clearly distinguishing it from sibling tools like 'gazette_categories'. No ambiguity about what the tool does.

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 provides a clear context: use when you need a list of Iulaan categories. However, it does not explicitly mention when not to use it or point to alternatives like 'search_iulaan' or 'browse_gazette' for more complex needs. The usage is implied rather than explicit.

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