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

No annotations are provided, so the description carries the full behavioral burden for a mutation. It does not say whether the cancellation is reversible, what happens if the request is already confirmed, whether permissions are required, or what the result looks like.

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, front-loaded sentence with no filler, so it reads efficiently. It is concise to a fault, though, leaving no room for the behavioral and parameter context the tool needs.

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 mutation tool with no annotations, no output schema, and an undocumented identifier parameter, the description is too thin. An agent cannot determine preconditions, side effects, or error behavior before invoking it.

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 one required parameter, action_id, with 0% schema description coverage, so the schema explains nothing beyond the name and integer type. The description never clarifies what an action_id refers to, how to obtain it, or how it maps to "une demande preparee".

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?

States a specific verb ("j'annule") and a specific resource ("une demande preparee non confirmee"), so the agent knows this cancels an unconfirmed/prepared request rather than an arbitrary action. It implicitly contrasts with the sibling confirmer_action but never names it.

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 qualifier "non confirmee" implies the tool only applies to requests that have not yet been confirmed, which gives a usable usage boundary. However there is no explicit when-to-use/when-not-to-use guidance and no mention of confirmer_action as the alternative for confirmed flows.

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