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

Annotations already declare readOnlyHint=false and destructiveHint=false, so the mutation/safety profile is covered and the description does not need to restate it. The description does add a real behavioral dependency (field shapes come from describe_resources), but it says nothing about validation of the free-form `data` object, whether unknown fields are rejected, or what happens on an invalid `type`.

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?

Two short sentences, front-loaded with the action and followed by the one operational instruction that matters. Nothing is padded, though the switch to French while sibling tools and the schema use English slightly hurts scanability.

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 generic write tool spanning dozens of resource types with no output schema, the description leans entirely on describe_resources for field shapes and never states what a successful call returns (e.g., the created record identifier) or how `data` is validated. The describe_resources pointer is the essential piece and it is present, but the definition is only minimally complete for a tool of this breadth.

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 0% for two required parameters, one of which is a 50-value enum and the other a free-form nested object, so the description carries real weight here. The pointer to describe_resources is a meaningful compensation for the opaque `data` payload, but the `type` enum is never explained and the referenced `name` is not a top-level parameter, which leaves the parameter model only partly resolved.

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 gives a clear verb and a generic resource ("Créer un élément du catalogue"), so an agent knows it is a create operation. However, it never mentions the `type` discriminator that actually defines what kind of catalog element is being created, and it does not distinguish this generic creator from the many specific siblings such as create_page, create_project, or create_workspace.

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 second sentence is genuine usage guidance: it tells the agent to supply `name` and to derive the remaining fields from describe_resources, which is an actionable pre-call step. There is no guidance on when to prefer this generic tool over the resource-specific create_* siblings, and no exclusions or error conditions are stated.

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