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

With no annotations provided, the description carries the full burden. It discloses that the data is public, which implies no authentication, and lists the specific scope. However, it does not explicitly mention absence of side effects, potential errors, or return type details, leaving some behavioral aspects unstated for a simple read operation.

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, well-structured sentence that front-loads the action and resource, then lists specific content. Every word adds value, with no redundancy or filler.

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 zero-parameter tool with no output schema, the description gives a reasonable overview of what to expect: statement, games, development status, and links. It lacks exact field names or format details, but the scope is clear enough for a simple GET.

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 baseline is 4. The empty schema is fully covered, and the description appropriately focuses on the return content rather than parameter syntax, which is irrelevant 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 uses the specific verb 'Get' and clearly identifies the resource as the public House Duck studio, listing the distinct content items (statement, current games, development status, canonical links). This differentiates it from sibling tools like get_post and list_posts, which are about blog posts.

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 implies the tool is for studio-related information, while sibling tools are for posts, providing clear context without explicit exclusions. It would be stronger with an explicit 'use this instead of get_post/list_posts' note, but the content list makes the intended use obvious.

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