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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description contributes the word "récentes", implying a bounded time window rather than the full history, but it does not say how many notifications are returned, whether a window is configurable, or how unread items are flagged.

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 short phrase, front-loaded with the verb and free of boilerplate — nothing extraneous. Its terseness is the only weakness, though the missing depth is better attributed to completeness than to structure.

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?

For a zero-parameter read tool with rich annotations and no output schema, the description is close to sufficient but leaves "récentes" undefined — no count, no time window, no indication of what a notification record contains. A single clause on recency and volume would make it complete.

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?

The tool takes no parameters and the input schema is an empty object, so there is no parameter semantics for the description to add. Baseline 4 applies for a zero-parameter tool with nothing to mis-document.

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?

"Voir les notifications récentes" gives a specific verb (voir) and resource (notifications) with a scope qualifier (récentes), making it distinguishable from the sibling dandori_mark_notifications_read. It stops short of explicitly naming that sibling or stating what is excluded, so it does not reach a 5.

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 when-to-use guidance: nothing says when to fetch notifications versus when to mark them read (dandori_mark_notifications_read), or how this relates to other read tools in the family. The only implied usage is that it surfaces recent items, which the agent must infer.

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