C2.8/5.0
Behavior2/5

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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and openWorldHint=false, so the safety profile is fully covered without the description. Beyond that, the description adds nothing — it does not explain what 'latest' means when today's edition is unpublished, whether a stale edition is returned, or how freshness is determined.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences, front-loaded with the resource. The second sentence is close to redundant with the required `persona` parameter already documented in the schema, but nothing is bloated.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema, full annotation coverage and 100% schema description coverage, most of the burden is carried elsewhere and the tool is simple (one required enum parameter). The only meaningful gap is that 'latest' semantics and the absence-of-edition case remain unexplained.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so both parameters (including the `fields` projection list) are fully documented in the schema. The description's 'such as founder' actually understates the enum's closed set of founder/investor, so it adds no meaning and is slightly less precise than the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names the resource ('latest published daily edition of one page'), but 'one page' is vague and the phrasing largely restates the title verbatim. It never distinguishes this tool from the sibling ud_get_edition, which appears to return an edition by a different selector, so an agent must open the schema to tell them apart.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The only guidance is 'Pass `persona` (such as founder)', which is a parameter instruction rather than a when-to-use rule. There is no mention of when to prefer this over ud_get_edition, no note about what happens if no edition has been published yet, and no exclusions at all.

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