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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is covered. The description usefully discloses that the tool yields a link rather than report content, which is behavior beyond the annotations, but adds nothing about auth needs, rate limits, or failure modes (e.g., missing slug).

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?

A single front-loaded sentence with no padding. It is efficient, though the phrasing ('Lien vers un exemple de rapport') is slightly ambiguous about exactly what is returned.

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 carries the return-value burden; it says a link is returned but not the format or behavior when slug/service is invalid. For an optional-parameter lookup tool with annotations covering safety, this is minimally adequate but leaves the agent guessing on output and error handling.

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?

With 67% schema coverage, the description compensates for the undocumented 'service' enum by explaining that 'test' maps to the example page and 'sml' to the ScanMyLove demo report. The slug and locale semantics are already well documented in the schema, so the added value centers on the service parameter.

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 the resource (a link to an example report) and distinguishes two variants: a test's example page and the ScanMyLove demo report. However, it largely restates the title 'Exemple de rapport' without a crisp verb (does it return a URL string, open a page, or fetch the report?) and never distinguishes itself from siblings like get_test or get_article.

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?

No when-to-use guidance or alternatives are given. The mention of 'pour un test' vs 'le rapport de démonstration ScanMyLove' hints at which service value to pick, but that is parameter mapping, not usage guidance for selecting this tool over siblings.

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