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

Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=false, so the write/idempotency profile is covered. The description adds genuine value by disclosing PATCH semantics (only provided fields are modified), disambiguating it from a full replacement, but omits permission requirements and any side effects.

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, completely front-loaded: the verb+resource leads and the update semantics follow. Every word earns its place with no filler.

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 an output schema present, the description needn't explain return values, and annotations cover the safety profile. The PATCH clarification plus a required id make the call mechanically clear; only usage routing between sibling product tools is left implicit.

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 100%, so all eight parameters are already documented in the schema. The description adds nothing param-specific beyond the general PATCH note, so the baseline of 3 applies when the schema does the heavy lifting.

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?

"Modifie un produit existant" states a specific verb (update) and resource (product), and "existant" scopes it to existing entities. It does not explicitly name sibling tools like create_product or get_product, but the operation is unmistakably an edit, so an agent can place it correctly.

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 implies PATCH-style usage by signaling that only supplied fields change, which helps an agent decide which parameters to pass. However, there is no explicit when-to-use guidance, no mention of prerequisites, and no routing to alternatives such as create_product or get_product.

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