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

Annotations already declare readOnlyHint and idempotentHint, so the safety profile is established. The description adds behavioral context by stating the result is 'a paged structured response,' which is useful beyond the annotations. No contradictions, but it does not explain pagination mechanics like page size or cursor handling.

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 concise sentence that immediately states the action and result format, with no filler or redundancy. It front-loads the purpose and efficiently conveys the key information.

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 simple list tool with no parameters and an existing output schema, the description covers the core purpose and mentions paging. It does not specify ordering or filtering, but these are likely handled by the output schema. The only notable gap is the title/description mismatch, but the tool is otherwise adequately described.

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?

There are no parameters in the input schema, so schema coverage is 100%. Per the rubric, 0 parameters yields a baseline of 4. The description appropriately does not add parameter-specific details because none exist.

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 'List' and clearly identifies the resource ('translators available in the system'). It distinguishes from the sibling 'translate-tool' by focusing on enumeration rather than translation. The title says 'translations' but the description says 'translators', which is a minor inconsistency, but the intended purpose is unambiguous.

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 over alternatives. There is no mention of the sibling 'translate-tool' or any conditions or exclusions for use. The usage is implied at best, but no explicit context is given.

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