Suggest fresh example domain

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

No annotations provided, so description carries full burden. It mentions returning an unused or least-recently-used domain, indicating a read-like operation. However, it doesn't disclose any side effects, permissions, or response format, leaving some gaps.

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 two sentences, concise and to the point. However, the second sentence is a bit cryptic; could be structured more clearly. No wasted words, but front-loading could be better.

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 has no parameters and no output schema, the description provides adequate context for its simple purpose. It explains the domain rotation context (Maths-specific) and the selection criterion (unused or least-recently-used), which is sufficient.

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?

No parameters, so schema coverage is 100%. The description adds meaning by specifying 'unused or least-recently-used' and 'Maths-specific rotation', which clarifies what the tool returns beyond the empty schema.

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 states the verb 'suggest' and resource 'fresh domain', with clear purpose of rotating object families for chapters. It differentiates from siblings like 'domain_usage' by specifying 'Maths-specific (example-domain rotation)', but the phrasing could be less ambiguous.

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?

Implied usage is for getting a domain for chapter rotation, but no explicit when-not or alternatives. Sibling 'domain_usage' might serve a different purpose, but the description doesn't clarify when to choose this over others.

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