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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the '[read]' tag is redundant. The description does add useful context: the endpoint path and the default value applied to the article type, which tells the agent what happens when the optional param is omitted.

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?

One compact sentence that front-loads the read nature and aggregation dimensions. Nothing wasteful, though the bracketed tag and raw endpoint path are of marginal value to an agent.

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?

A simple read-only reporting tool with annotations covering the safety profile, so not much is required. However, with no output schema and no enum on the parameter, the description leaves the agent guessing about the response shape and the allowed article-type values.

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 coverage is 0%, so the single parameter seliee_article_type is undocumented in the schema. The description names it and confirms the default PUBLISH, but never explains what other values are valid or what the type actually means (status? content category?), so it only partially compensates.

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 and aggregation dimensions (articles grouped per website and day) plus the underlying endpoint, which lets an agent distinguish it from other report tools like get_website_report or get_metric_report. It stops short of explicitly naming a sibling alternative.

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?

Nothing says when to call this versus the many other report tools (get_website_report, get_leads_report, get_social_report). The only usage hint is the implicit 'articles per website and day' framing, with no exclusions or prerequisites.

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