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

Annotations provide openWorldHint=true and idempotentHint=true, indicating the tool can handle unknown inputs and repeated operations safely. The description adds no behavioral details beyond this, such as permission requirements, side effects, or rate limits, but doesn't contradict the annotations either.

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, direct sentence that efficiently conveys the core action without unnecessary words. It's front-loaded with the main purpose, making it easy to parse and understand quickly.

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 moderate complexity (2 required parameters, no output schema) and annotations covering idempotency and open-world handling, the description is minimally adequate. However, it lacks details on error conditions, response format, or integration with sibling tools, which would enhance completeness for an agent.

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%, with clear parameter descriptions in the schema. The tool description doesn't add any semantic context beyond what the schema provides, such as explaining the relationship between realm and themeIdentifier or usage examples, but the schema adequately covers the basics.

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 the action ('Set') and the resource ('a theme as the default for a realm'), making the purpose understandable. However, it doesn't explicitly distinguish this tool from sibling tools like 'updateTheme' or 'setVariable', which could handle similar operations in different contexts.

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 no guidance on when to use this tool versus alternatives. With sibling tools like 'updateTheme' and 'setVariable' available, there's no indication of prerequisites, specific scenarios, or exclusions for using setDefaultTheme, leaving usage context ambiguous.

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