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

Annotations already declare readOnlyHint, destructiveHint=false, and openWorldHint=false, so safety is covered. The description adds almost nothing beyond that: it does not say what period the statistics cover, whether variants are A/B tests or page versions, or what the payload looks like, despite there being no output schema.

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?

It is a single short sentence with no waste, but it is under-specified rather than concise; the brevity removes information an agent needs, and it is in French while the rest of the tool surface is English.

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, a 0%-covered parameter, and a crowded sibling namespace of page/stats tools, the description should explain the returned metrics, the time window, and which id is expected. It covers none of this.

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% and there is one required parameter 'id' with no description in the schema. The description never clarifies that 'id' is a page identifier (as opposed to a site, project, or revision id), leaving the single parameter's meaning to inference.

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 states a resource (a page) and a vague verb ('Statistiques de visite et variantes'), so an agent can guess it returns visit metrics and variant info for one page. However, 'variantes' is undefined and the wording does not distinguish it from nearby siblings such as get_newsletter_stats, get_site_activity, or get_page_version.

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?

There is no guidance on when to call this versus alternatives like get_page, get_page_version, get_site_activity, or get_newsletter_stats. The agent must infer the selection criteria entirely from the name.

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