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

With no annotations, the description carries the full burden, and it does disclose meaningful behavioral traits: content is cleaned of site pages, rank change vs. prior day, new entries, week-long regulars, and automated surges are flagged separately, plus the underlying data source (Wikimedia pageviews, CC0). Missing are auth/invocation traits, but for a public read-only tool this is solid disclosure.

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?

Three sentences, front-loaded with the core resource and scope before the secondary signals and provenance. Efficient and well-ordered, though the middle list is dense and could be tightened.

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?

No output schema exists, so the description appropriately describes return content (rank change, new entries, regulars, surge flags). For a 2-param read-only tool with full schema coverage this is nearly complete; default lang behavior and the meaning of the limit scale are the only gaps.

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?

Schema description coverage is 100%, so both parameters (lang, limit) are documented in the schema. The prose adds no parameter-level meaning, so the baseline 3 applies.

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?

States a specific resource (yesterday's most-viewed Wikipedia articles) and a specific scope (any language, cleaned of site pages). It is concrete enough to distinguish from generic search tools, but it never names or contrasts with the closely related siblings attention_topic and attention_spikes, so sibling differentiation is left implicit.

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 phrase 'A daily read of what people are paying attention to' implies the intended cadence and context, but there is no explicit when-to-use, when-not-to-use, or alternative routing, despite multiple attention_* siblings that overlap in intent.

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