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

The annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is known. The description adds one genuinely useful behavioral fact beyond them: deleting the webhook also removes its history, which is a wider blast radius than an agent would assume. It does not say whether the operation is irreversible or requires confirmation, or whether it affects deliveries in flight.

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 one short, front-loaded sentence with no filler; the deletion scope is stated first. It is under-specified rather than bloated, so this dimension holds up, although the French phrasing is inconsistent with the rest of the toolset.

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?

This is a destructive, irreversible-looking mutation with no output schema and a wholly undocumented identifier. The description never says what the id refers to, whether the deletion can be undone or rolled back, or what happens to in-flight deliveries. For the risk profile of this tool, that leaves important gaps.

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?

There is a single required parameter, 'id', and schema description coverage is 0%, so the schema supplies no meaning at all. The description must therefore explain whether the id is the webhook id or the form id, but it says nothing about the parameter. An agent has to guess which identifier to pass.

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 delete verb ('Supprimer') and a scope ('le point d'entrée et son historique'), which is more than a tautology. But it calls the resource 'le point d'entrée' (the endpoint) rather than the webhook, so an agent must infer the resource from the tool name, and it does not distinguish this from sibling delete-style tools or from update_form_webhook. The French wording in an otherwise English toolset adds friction.

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 or when-not-to-use guidance. It never points to the obvious alternatives, such as update_form_webhook to keep the webhook and change it, or list_form_webhooks or describe_form_webhooks to confirm which webhook to remove. The only implied usage is 'when you want to remove one', which the name already conveys.

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