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

With no annotations, the description carries the behavioral burden. It clearly discloses the output scope and what is deliberately excluded, which is meaningful context beyond the tool name. It does not state obvious operational details like read-only status or return shape, but for a zero-parameter get tool this is a minor gap.

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 compact and every sentence adds relevant scope or exclusion information. The phrasing is dense and somewhat jargony, but it is not padded and the core result is front-loaded.

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?

With no output schema and no annotations, the description must explain the return value and scope. It does so by specifying the exact set of entries and listing what is not included. It is adequate for an agent to decide whether to call this tool, though it could be stronger by naming relevant sibling alternatives.

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 input schema is empty, so there are no parameters for the description to clarify. Per the baseline for zero-parameter tools, this is appropriate; the description need not add parameter-level semantics.

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 identifies a specific result: 'exact visible, ratified language entries absent from the latest published public-domain bundle.' This is clear about the resource and scope, though it does not explicitly distinguish itself from sibling tools by name.

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 when to use the tool: when you need the exact visible, ratified entries missing from the bundle. It mentions exclusions ('required bundle-field checks, evidence summaries, optional flagship-explanation status and not-shortlisted status remain separate') but does not name alternative tools or give explicit when-not-to-use guidance.

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