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

Annotations already declare readOnly=false, destructive=false, idempotent=false, openWorld=false, so the safety profile is covered. The description adds nothing further: it doesn't say what is created, what defaults are applied to status/priority, or whether duplicates are permitted.

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?

One short sentence with no wasted wording and the core action front-loaded, which is good. But for a 9-parameter mutation tool the brevity crosses into under-specification rather than economy.

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?

A creation tool with 9 parameters, three enums, and no output schema needs more than a one-liner; the agent gets no defaults, no field guidance, and no indication of what a successful creation returns. Relative to the tool's complexity, the description leaves major 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?

Schema description coverage is only 56% across 9 parameters, and the description contributes nothing beyond the examples, which loosely gesture at the 'category' enum. Nothing explains status values, priority, target_price, reminder_at, or planned_date semantics, so the uncovered half stays unexplained in both places.

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 concrete verb+resource ('Créer une envie') and clarifies the domain with examples ('achat, voyage, expérience…'), so the agent knows this records a wish/desire item. It does not differentiate from the many sibling create_* tools (goal, project, list, note) beyond the resource name itself.

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 explicit when-to-use or when-not-to-use guidance, and no mention of prerequisites or relationship to sibling creators. Usage is only implied by the parenthetical examples of wish types.

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